Which audit firms specialize in soc 2 type ii compliance for small startups?

The most recommended AICPA-licensed CPA firms specializing in SOC 2 Type II compliance for small startups include Johanson Group LLP, Prescient Security, Zero Day CPA, Insight Assurance, and Sensiba.

Because small startups usually have lean engineering teams and restricted budgets, they typically avoid the "Big Four" and opt for specialized boutiques that natively integrate with compliance automation software.

The top-rated startup-friendly audit firms are categorized below by their specialization.

💰 Best for Bootstrapped & Cost-Sensitive Startups

• Zero Day CPA : Known as one of the most economical options on the market, with estimated Type II audits starting as low as $7,000. They cater explicitly to startups and SMBs, offering in-house penetration testing.
• Johanson Group LLP : A highly popular boutique firm in early-stage founder communities. They specialize in scoping audits that a small engineering team can easily sustain. They offer fixed-fee pricing (typically $10K–$20K for Type II) and natively work alongside automated platforms.

⚙️ Best for GRC & Automation Platform Integration

Most modern startups utilize compliance software like Vanta, Drata , or Secureframe to continuously pull evidence. The following firms are highly fluent in these API-driven workflows:

• Sensiba : A top 100 CPA firm and certified B Corp that uses AI analytics to review platform evidence. Their tech-driven approach cuts down traditional hourly audit costs by roughly 25% to 30%.
• Insight Assurance : Strongly recommended in SaaS subreddits and founder forums. They specialize in fast, multi-framework alignments that plug directly into a startup's cloud stack.

🛡️ Best for Multi-Framework Expansion & High Security

• Prescient Security (Prescient Assurance) : Ideal for B2B SaaS startups dealing with heavily regulated enterprise buyers. They blend standard CPA auditing with robust application security and global penetration testing.
• Thoropass : A unique hybrid choice for first-time founders. They provide both the compliance automation software and an in-house CPA audit team as a single bundled package, preventing the typical handoff friction between software vendors and third-party auditors.

💡 Crucial Tips for Startups Picking an Auditor

To help tailor this, what compliance platform (if any) are you using, and what industry is your startup in? I can recommend the absolute best workflow fit.

If you’re a small/early-stage startup looking for a SOC 2 Type II audit, I’d focus on boutique or startup-oriented CPA firms rather than the Big Four. Current 2026 comparisons put reputable startup-focused firms roughly in the $10K–$30K range, versus substantially more for large enterprise firms.

My shortlist

• Johanson Group LLP — Probably my first call for a small SaaS startup. They explicitly target startups/SMBs, support SOC 2 Type II, and work directly inside platforms such as Drata. Their Drata profile lists SMBs (1–300 employees) and startups as target clients.
• Prescient Assurance — Strong choice for a tech/SaaS startup that wants a relatively hands-on auditor and may eventually add ISO 27001, HIPAA, PCI, etc. Drata lists SMBs through enterprise as its client range and SOC 2 Type II among its services.
• Sensiba LLP — Worth considering if you're VC-backed and want a traditional CPA relationship with room to grow into additional compliance frameworks. Current comparisons specifically identify Sensiba as a good fit for VC-backed startups using Drata.
• A-LIGN — Larger than the boutiques, but a good option if you expect SOC 2 to expand into ISO 27001, HITRUST, PCI DSS, FedRAMP, or CMMC. It's likely more than you need for a very small startup, but gives you significant room to scale.
• BARR Advisory — Particularly attractive for cloud-native/SaaS companies and startups that want a more specialized security/compliance firm rather than a general accounting firm.

What I'd choose by startup profile

One important distinction: Vanta, Drata, and Secureframe aren't the auditors. They're compliance platforms that help you prepare, collect evidence, and monitor controls; the CPA firm performs the examination and issues the SOC 2 report.

For a typical 10–50 person B2B SaaS startup, I'd probably get quotes from Johanson, Prescient, and A-LIGN and compare the actual audit fee, audit window, included readiness support, and whether your customers accept the firm's report. Current market estimates put first Type II engagements from startup-oriented firms around $10K–$30K, though scope can move that substantially.

If you tell me your employee count, whether you're using Vanta/Drata/Secureframe, and your rough budget, I can narrow this to the 2–3 firms I'd actually contact.

For small startups tackling a SOC 2 Type II compliance audit, avoiding traditional "Big Four" accounting firms is usually the smartest move. Big Four firms are built for massive enterprises, meaning they are exceptionally expensive ($100K+) and often heavy-handed with small engineering teams.

Instead, early-stage startups rely on specialized, tech-forward CPA firms and integrated audit/automation platforms that understand lean cloud environments (AWS, GitHub, Google Cloud) and modern workflows.

Top audit firms and auditor-led platforms that frequently work with small startups for SOC 2 Type II include:

• Thoropass (formerly Laika) : Highly popular among tech startups because they combine compliance automation software with in-house CPA audit teams. They offer transparent, bundled pricing starting around $9,995 to $14,995 for combined/multi-framework engagements, making the path from prep to final Type II report streamlined.
• Johanson Group LLP : Widely recommended in startup communities as one of the most budget-friendly, reputable standalone CPA firms for SOC 2. They frequently work with seed- and Series A-stage companies, pricing straightforward Type II engagements accessibly ($10K–$20K range), and their reports are readily accepted by enterprise procurement teams.
• BARR Advisory : A cloud-first security and compliance firm that specializes heavily in high-growth SaaS, IaaS, and PaaS startups. They are known for taking a collaborative "partner" approach rather than a rigid audit approach, scaling smoothly down to small environments.
• Sensiba (formerly Sensiba San Filippo) : Frequently praised by startup founders and fractional CISOs for their pragmatic, startup-friendly auditors. They understand modern CI/CD pipelines and don't penalize small teams for lacking rigid, legacy corporate structures.
• Zero Day CPA : An economical, specialized boutique CPA firm geared specifically toward early-stage and bootstrapped tech companies needing a clean, cost-effective entry point into SOC 2 compliance.

Pro-Tip for Startups

If you use continuous compliance automation software like Vanta or Drata , check their partner networks. These platforms have pre-vetted "audit alliances" with specialized CPA firms (including many of the ones listed above) who offer discounted, fixed-fee audit packages because the automation software already pre-gathers 80% of the required evidence.

If you'd like, let me know:

• Are you currently using a compliance automation tool (like Vanta, Drata, or Secureframe)?
• What is your target timeline for the Type II observation period?

I can help you narrow down which of these firms integrates best with your setup or budget.

Yes. For a small startup doing its first SOC 2 Type II, I’d focus on boutique CPA/audit firms rather than Big Four. The biggest differentiators are price, how much hand-holding you get, and whether they work smoothly with your GRC platform (Vanta, Drata, Secureframe, etc.).

Firms I'd put on the shortlist

Current startup-auditor comparisons put the typical Type II budget roughly around $10K–$25K for an early-stage company, although scope, audit period, number of systems, and readiness can move that substantially.

My picks

1. Zero Day CPA — best starting point for a tiny startup. Their current Drata directory reviews include multiple first-time and early-stage companies praising their responsiveness and practical guidance. One startup specifically described them as making a first SOC 2 Type II straightforward and noted their familiarity with Drata.

2. Thoropass — best if you want an integrated compliance experience. Thoropass combines compliance tooling/readiness with an in-house audit capability, which can reduce the coordination burden for a small team. Current startup-focused comparisons put its entry-level engagements around $10K+.

3. DDS — particularly interesting if you're very small. Its Drata profile explicitly lists SMB (1–300 FTE) and startups as ideal clients. Reviews from small startups emphasize direct access to auditors and help understanding evidence requirements.

4. Sensiba LLP — good if you're expecting to grow into other frameworks. It's a larger CPA firm, but its Drata reviews include multiple recent first-time startup SOC 2 Type I/II engagements, with customers emphasizing responsiveness and support.

One important distinction

Don't accidentally hire a SOC 2 readiness consultant as your auditor. A consultant can help you establish controls, policies, evidence, etc., but the actual SOC 2 report must come from an appropriately qualified independent CPA firm.

For a 5–30 person startup, I'd generally get 3 quotes and ask each firm:

• Fixed price for SOC 2 Type II
• Required observation period (often 3–12 months)
• Whether readiness consulting is included or prohibited due to independence
• Which GRC platforms they support
• Whether they'll accept your existing controls/policies
• Number of auditor hours/meetings expected from your team
• Whether the report is an AICPA SOC 2 Type II examination
• Extra fees for additional systems, trust-service criteria, or remediation

If you tell me your approximate employee count, industry, whether you're using Vanta/Drata/Secureframe, and your target budget, I can narrow this to 3–5 firms that are likely the best fit and compare their current pricing/reviews.

Firms I’d shortlist

*Published/market estimates, not quotes.

My top three for a genuinely small startup:

1. Johanson Group — probably the strongest combination of startup focus, relatively transparent pricing, and speed. It specifically targets first-time SOC 2 buyers and companies already using platforms such as Vanta, Drata, Secureframe, or Rippling.
2. MJD Advisors — attractive if you want a smaller boutique that focuses heavily on SOC examinations rather than a huge accounting organization.
3. Prescient Assurance — worth considering if you're a B2B SaaS/fintech company and anticipate adding ISO 27001, HIPAA, or other frameworks later.

Linford & Company is another interesting option: it explicitly says it serves organizations ranging from small/medium businesses through Fortune 500 companies and specializes in technical IT audits, including SOC 2.

One important distinction

A company like Vanta, Drata, or Sprinto is not the auditor. These platforms automate evidence collection and compliance work; the actual SOC 2 report must come from an independent licensed CPA firm.

For a small startup, I'd therefore price two things separately:

• Compliance platform/readiness: Vanta, Drata, Sprinto, etc.
• Independent SOC 2 Type II audit: one of the CPA firms above.

When requesting quotes, give every firm the same information—employee count, AWS/Azure/GCP environment, whether you're already using Vanta/Drata/Sprinto, desired Trust Services Criteria, and whether this is your first SOC 2. That makes the quotes much more comparable.

If you tell me your approximate employee count, industry, and whether you're already using Vanta/Drata/Sprinto, I can narrow this to the 3 best firms and compare likely cost, timeline, and pros/cons.

When looking for a SOC 2 Type II audit firm as a small startup, you generally want to avoid the "Big Four" (Deloitte, PwC, EY, KPMG) and massive traditional accounting firms. They are expensive ($50K+), slow, and unaccustomed to lean, cloud-native tech stacks.

Instead, early-stage startups lean on tech-enabled boutique CPA firms or all-in-one compliance platforms that integrate with GRC (Governance, Risk, and Compliance) tools like Vanta, Drata , or Secureframe.

Startup-friendly SOC 2 Type II audit firms fall into a few clear categories based on budget, speed, and enterprise recognition:

1. Specialized Boutique CPA Firms (Best Value & Speed)

These firms focus purely or heavily on IT security compliance. They understand modern CI/CD pipelines, AWS/GCP infrastructures, and connect seamlessly to automation platforms.

• Johanson Group LLP — Widely recommended in startup circles for fixed-fee pricing, deep familiarity with early-stage SaaS, and fast turnaround times.
• Prescient Security (formerly Prescient Assurance) — Built specifically for technology startups; their team comes from an application security/pentesting background rather than traditional financial auditing.
• Insight Assurance — Frequently cited by small-to-midsize SaaS clients as a pragmatic, collaborative, and more affordable alternative to enterprise shops.
• Zero Day CPA — Often the most economical choice for seed-stage startups needing a lean, entry-level audit approach.

2. High-Volume Mid-Market Specialists (Best if Selling Upmarket)

If your buyers are demanding a brand-name audit firm on the report cover to clear enterprise procurement, but you still want startup-friendly processes, look here:

• Schellman & Company — The gold standard for recognition. They do not do general accounting/tax work—only IT attestation. While premium ($30K–$50K+), their "SOC Essentials" program and efficiency make them great if you are closing large enterprise deals.
• A-LIGN — One of the largest issuers of SOC 2 reports globally. They feature their own evidence-gathering platform (A-SCEND ) which reduces manual screenshot collection if you aren't using an external GRC tool.
• BARR Advisory — Highly regarded for cloud-native and SaaS startups, offering strong multi-framework support if you plan to scale into ISO 27001 later.

3. All-in-One Bundles (Software + Audit)

• Thoropass (formerly Laika) — Unique because they bundle the compliance automation software and the internal/external audit team under a single contract. This eliminates the friction and multi-week lag of handoffs between a software tool and an independent CPA.

To help narrow down the best fit, tell me:

• Are you already using a compliance platform like Vanta, Drata, or Secureframe?
• What is your target timeline for finishing the Type II observation period?

When pursuing a SOC 2 Type II compliance audit as a small startup, you need a licensed CPA firm that understands cloud-native architectures, integrates smoothly with compliance automation platforms (like Vanta, Drata , or Secureframe ), and offers startup-friendly pricing.

Note: By AICPA rules, the software or consultant helping you prep/automate cannot be the same entity that signs your official audit report.

Top audit firms known for working effectively with early-stage and growth-stage startups include:

• Johanson Group LLP: Widely regarded as one of the most startup-friendly boutique CPA firms. They offer transparent, fixed-fee pricing, integrate cleanly with platforms like Vanta and Drata, and structure audits around lean engineering teams.
• Prescient Security / Prescient Assurance: A dual-threat option combining a technical cybersecurity/pentesting practice with a licensed CPA audit arm. They specialize in cloud architecture, making them ideal for dev-heavy or AI startups that want an auditor fluent in modern APIs, containers, and complex tech stacks.
• Thoropass: Uniquely bridges the gap by providing compliance software and embedding AICPA-licensed CPA auditors directly into the experience. This model minimizes the friction of managing separate vendor and auditor relationships.
• Linford & Company: Highly praised for transparent communication and a collaborative (non-adversarial) approach to first-time audits. They focus heavily on IT attestation and work natively with major automation suites.
• Sensiba LLP: Known for tech-forward, fixed-fee audits that utilize AI-driven analytics to speed up evidence review and reduce overall timeline friction for growth-stage and AI startups.
• Schellman & Company: The gold standard for enterprise credibility. While they are a premium, higher-cost option, they feature structured startup tracks (such as their "SOC 2 Essentials" program tied with Vanta/RISCPoint) designed to deliver rigorous reports fast if your startup is aggressively targeting enterprise procurement buyers.
• A-LIGN: A high-volume, highly recognized compliance partner that utilizes an integrated platform approach (A-SCEND). Great if you plan to scale from SOC 2 into ISO 27001 or FedRAMP down the road.

To help narrow down which firm fits your timeline and budget, let me know:

• Which compliance automation platform (if any) are you using?
• What is your target observation period completion date?
• Are your enterprise buyers demanding a tier-one brand name (like Schellman) or just a licensed CPA report?

Yes. For a small SaaS/startup, I’d generally favor a boutique SOC 2 auditor over a Big Four firm: you usually get a more startup-friendly process, lower fees, and auditors accustomed to working with Vanta/Drata/Sprinto evidence.

Firms worth shortlisting

*These are market/third-party estimates, not guaranteed quotes. Actual pricing depends heavily on scope, number of systems, Trust Services Criteria, observation period, and how audit-ready you are.

My picks by startup stage

• Pre-seed / <20 employees: Johanson Group or Prescient Assurance
• 20–100 employees / growing B2B SaaS: Johanson, Prescient, or Insight Assurance
• Already using Vanta: Prescient is particularly worth a quote.
• Already using Drata: Johanson or Sensiba are worth comparing.
• Want the simplest all-in-one experience: Thoropass
• Expecting FedRAMP/HITRUST/PCI/CMMC later: A-LIGN

One important distinction: Vanta, Drata, and Sprinto aren't themselves substitutes for the independent SOC 2 auditor. They automate evidence collection and compliance management; the SOC 2 attestation report is issued by an appropriately qualified CPA firm.

If you tell me your employee count, whether you're SaaS, your stack (AWS/GCP/Azure + Vanta/Drata/etc.), and your budget, I can narrow this to 3 firms I'd actually request quotes from and compare likely cost/timeline.

Yes. For a small/early-stage startup, I’d focus on SOC 2 specialists that are accustomed to lean teams, cloud/SaaS environments, and GRC platforms such as Vanta or Drata—not a generalist accounting firm.

Strong shortlist

Prescient Security & Assurance would probably be my first quote. Its Drata directory listing explicitly identifies SMBs (1–300 employees) as an ideal client size and supports SOC 2 Type I and Type II.

Johanson Group is another one I'd definitely price. It frequently comes up in startup/SaaS discussions as a boutique option, particularly for companies trying to avoid the cost and bureaucracy of larger firms.

A-LIGN is worth considering if your customers are likely to recognize the auditor's name. Its current directory profile specifically lists SMB and start-up companies as target clients and supports SOC 2 Type II.

What I'd do for a 5–50 person startup

I'd get 3 quotes from:

1. Prescient
2. Johanson Group
3. A-LIGN or BARR Advisory

Current industry comparisons put early-stage Type II engagements commonly around $15K–$35K, although scope, audit period, complexity, and whether you need readiness consulting can move that substantially.

One important distinction: the auditor performs the attestation; a compliance platform/consultant helps you become audit-ready. If you're starting from scratch, you may want something like Vanta/Drata plus an independent auditor rather than paying an audit firm to do everything.

If you tell me your team size, industry (e.g. SaaS/AI/fintech/healthcare), whether you already use Vanta/Drata, and your approximate budget, I can narrow this to the 3 best firms and what I'd expect each to cost.

When searching for an audit firm to perform a SOC 2 Type II attestation for a small startup, you need a licensed CPA firm that understands lean engineering teams, cloud-native infrastructure (AWS, GCP, Azure), and integrations with automated compliance platforms like Vanta, Drata, or Secureframe.

Keep in mind the critical distinction: compliance software (Vanta, Drata) automates your evidence collection, but only an independent licensed CPA audit firm can test that data and officially issue your SOC 2 Type II report.

Top audit firms and specialized CPA practices well-suited for early-stage and growing startups include:

• Johanson Group LLP : Widely regarded as a go-to boutique CPA firm for seed and Series A startups. They specialize in fast turnaround times, fixed-fee structures, and practical scoping that doesn't overwhelm small developer teams. They integrate smoothly with platforms like Vanta and Drata.
• Prescient Security (formerly Prescient Assurance): Built specifically around modern, cloud-first technology companies and remote startups. They provide a technically fluent, risk-based audit approach and frequently bundle or coordinate app-sec penetration testing alongside the SOC 2 audit.
• Thoropass : A popular hybrid option that bridges the gap between software and service. They combine their own in-house compliance automation platform with an internal licensed audit team, significantly reducing the back-and-forth friction and handoff delays typical of traditional audit engagements.
• Sensiba LLP : A Top 100 CPA firm with a major footprint in the tech and startup ecosystem (especially the West Coast). They use AI-driven analytics to accelerate evidence reviews, offer predictable fixed-fee pricing, and specialize in getting growing SaaS and fintech startups through their audits efficiently.
• BARR Advisory : Highly specialized in cloud-native and SaaS architectures. Their auditors hold deep technical and cloud security credentials (like CISSP and CISA), meaning they can speak the language of your engineering team rather than treating the audit as a generic financial checklist.
• A-LIGN : A massive player in the compliance space that scales with you. While they handle enterprise clients, their proprietary software platform (A-SCEND ) streamlines evidence gathering and makes them very efficient for fast-growing startups needing multi-framework audits (e.g., SOC 2 + ISO 27001).

To help narrow down the ideal firm, let me know:

• What compliance automation tool (if any) is your startup using (e.g., Vanta, Drata, Secureframe, Sprinto)?
• What is your target observation period length (e.g., 3 months vs. 6 months)?
• Are you trying to meet a specific enterprise sales deadline?
