What's a good single sign-on (SSO) provider that's easy to set up for a startup with about 50 users?

For a startup with ~50 users, I’d usually optimize for easy setup, MFA enforcement, SaaS app integrations, and painless offboarding rather than enterprise-heavy identity governance. Good choices:

My default picks for a 50-person startup:

1. Already on Microsoft 365 → Microsoft Entra ID
2. Cloud-native, mixed apps, no strong IT stack → JumpCloud
3. Expecting rapid growth, enterprise customers, or SOC 2 pressure → Okta
4. Building a SaaS product with customer accounts → Auth0

Before choosing, check that it supports:

• SAML and OIDC (for app integrations)
• MFA enforcement
• SCIM provisioning/deprovisioning (automatic account creation/removal)
• Google Workspace or Microsoft directory sync
• Your current apps (Slack, GitHub, AWS, Notion, Jira, etc.)

For 50 users, I’d avoid over-engineering: a good rollout can often be “connect identity provider → enable MFA → connect top 10 apps → document offboarding.”

If you tell me your stack (Google Workspace vs Microsoft 365, GitHub/AWS/Slack/etc.) and whether you need SOC 2, I can narrow this to a top 1–2 choices.

For a startup with around 50 users, the "best" SSO provider depends on whether you mean Internal SSO (so your 50 employees can log into Slack, GitHub, Google Workspace, AWS, etc.) or Customer SSO (so your B2B SaaS customers can log into your product).

Assuming you mean Internal Workforce SSO for your team, here are the top three easiest-to-set-up options depending on your current stack:

• 1. Google Workspace (Built-in) — Best if you already use Gmail/Google for business.
  • Why it’s great: If your 50 users are already logging in via Google Workspace (specifically on the Enterprise or Business Plus tiers), you actually already have a lightweight SAML/OIDC identity provider. You can connect standard apps (like Slack, GitHub, Notion, Zoom) directly through the Google Admin console without paying for or setting up a separate third-party service.
  • The Catch: Advanced features like automated user provisioning (SCIM) or granular conditional access policies require higher Google Workspace tiers.
• 1. JumpCloud — Best standalone cloud directory and device management.
  • Why it’s great: JumpCloud is practically tailor-made for startups of your size. It functions as an open directory-as-a-service that lets you manage user access to applications (via SAML/OIDC) and manage employee laptops (Mac/Windows MDM) from a single pane of glass. It is modern, incredibly intuitive, and doesn't require an enterprise IT background to configure.
  • Pricing: They have modular pricing if you just want core identity and SSO, making it very digestible for a 50-person team before you start scaling into hundreds of employees. You can test the waters via the JumpCloud Site.
• 1. Microsoft Entra ID (formerly Azure AD) — Best if you are a Microsoft 365 shop.
  • Why it’s great: If your startup runs on Outlook, Teams, and Windows environments, Entra ID is a no-brainer. The integration with Microsoft ecosystem apps is seamless, and the baseline security/MFA configurations are robust.
  • The Catch: The UI can feel a bit clunky and over-engineered compared to newer, developer-friendly competitors, but it scales endlessly.
• 1. Okta Workforce Identity Cloud — The Gold Standard (with a caveat).
  • Why it’s great: Okta connects to literally every app on the planet with pre-built integrations and bulletproof security.
  • The Catch: For a 50-person startup, Okta can be overkill and significantly more expensive per user than JumpCloud or leveraging Google Workspace. Implementation can also involve more sales friction and enterprise-focused onboarding overhead.

(Note: If you meant you are building a B2B product and need to add SSO for your customers to log into your app, look directly at WorkOS or Kinde , which abstract away SAML/OIDC complexities for developers).

To help narrow this down:

• What applications do your 50 users primarily need to log into?
• Are you already anchored to Google Workspace or Microsoft 365 for employee emails?

For a startup of about 50 users looking for an SSO provider that is fast and painless to set up, JumpCloud or Logto stand out as top choices depending on your exact tech stack and whether you need workforce identity (internal employees) or customer identity (B2B SaaS app users).

Here is a breakdown of the best options tailored for a ~50-person startup:

• JumpCloud : Best all-in-one directory and workforce SSO. It handles user lifecycle management, device management (MDM), and SAML/OIDC SSO out-of-the-box. It’s remarkably easy to spin up without a dedicated IT team, and it offers a generous free tier for up to 10 users, scaling predictably as you grow.
• Logto : Best developer-friendly, open-source-backed cloud IAM if you are building a product and need customer-facing/B2B auth or quick developer integration with modern stacks. It features a fantastic UI, easy multi-tenancy, and rapid setup.
• Auth0 (by Okta) : The gold standard for developer flexibility and robust integrations. Extremely powerful, but can feel like overkill and get expensive quickly for a small startup compared to simpler alternatives.
• Google Workspace / Microsoft Entra ID (formerly Azure AD) : If you already use Google Workspace or Microsoft 365 for your company email and docs, you already have a lightweight identity provider. You can enable basic SAML apps and Google/Microsoft login directly without paying for a separate third-party tool.

To help narrow down the best fit, tell me:

• Are you setting this up for internal employees (workforce) or external users logging into your app (customer identity)?
• Do you already use Google Workspace or Microsoft 365 for your team's emails?

For a 50-person startup, I’d shortlist Okta, Microsoft Entra ID, and JumpCloud. My default recommendation would be Okta if you want the simplest dedicated SSO platform and expect to grow.

My picks

• Okta — best overall

• Very mature SSO/MFA and a huge catalog of SaaS integrations.

• Okta’s current Workforce Identity Starter plan is $6/user/month, so roughly $300/month for 50 users, with SSO, MFA, Universal Directory, and 5 Workflows. There is a $1,500 annual contract minimum.

• Particularly attractive if you have lots of SaaS apps and want something your IT/admin team can manage without much identity expertise.

• Microsoft Entra ID — best if you're already Microsoft-heavy

• If you're already paying for Microsoft 365, check what identity capabilities you already have before buying another provider.

• Entra is particularly compelling if you're using Microsoft 365, Azure, Windows devices, and Teams.

• The downside for a small startup is that its configuration can feel more enterprise-oriented than Okta.

• JumpCloud — best if you also want device management

• Combines SSO/MFA with directory and device management, which can be useful if you don't already have separate MDM tooling.

• Its SSO product is currently $11/user/month annually ($550/month for 50 users), with a 30-day trial.

• I'd particularly consider it for a Mac-heavy startup where you want identity and endpoint management in one place.

What I'd choose

For 50 users, I wouldn't over-engineer this. You want SAML/OIDC SSO + enforced MFA + automated provisioning/deprovisioning (SCIM) at minimum. If you're pursuing SOC 2, having centralized access control and clean offboarding is especially useful.

If you tell me whether you're using Google Workspace or Microsoft 365, and roughly how many SaaS apps you have, I can narrow this to a single recommendation.

For a startup with around 50 users, the best single sign-on (SSO) provider depends entirely on what workspace tools you are already using . At this scale, you want something that minimizes administrative overhead, avoids the "enterprise tax" (expensive per-user add-ons), and sets up in an afternoon.

The top, easy-to-deploy options for a 50-person startup include:

1. Google Workspace (or Microsoft Entra ID)
   • Best for: Startups already living inside Google or Microsoft ecosystems.
   • Why it’s great: If your team already uses Gmail, Google Docs, or Microsoft 365, you already have an Identity Provider (IdP). You don't need Okta or a third-party tool just yet. Google Workspace and Microsoft Entra ID natively support SAML and OIDC integrations for thousands of popular apps (like Slack, Notion, GitHub, and Jira).
   • Setup difficulty: Very easy if you have basic admin familiarity; zero extra cost if you're already on a Business/Enterprise tier that supports SSO.
2. JumpCloud
   • Best for: Cloud-first startups that need device management (MDM) alongside SSO.
   • Why it’s great: JumpCloud is a cloud directory service built specifically for small-to-midsize businesses. It handles user authentication, multi-factor authentication (MFA), and can manage/lock down Mac and Windows laptops. It is far less complex and bloated than enterprise legacy tools.
   • Setup difficulty: Straightforward and intuitive, with a generous free tier for your first few users before scaling up. You can check it out on the JumpCloud Site.
3. Rippling
   • Best for: Startups using Rippling for HR and Payroll.
   • Why it’s great: If you use Rippling for HR, their IT/Identity product lets you tie app provisioning and SSO directly to your HR data. When you onboard a new employee in Rippling, they automatically get an email, a laptop setup, and access to all company apps via SSO. When they leave, access is instantly revoked.
   • Setup difficulty: Incredibly fast if you are already synced into their HR platform.
4. WorkOS
   • Best for: B2B SaaS startups that need to offer enterprise SSO to their own customers.
   • Why it’s great: If by "SSO for a startup" you mean your engineering team needs to add enterprise login capabilities (SAML/SCIM) into the product you are building, WorkOS is custom-built to make this happen with a few lines of code without becoming an identity infrastructure expert.

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

• Are you looking for workforce SSO (for your 50 employees to log into internal tools) or customer-facing SSO (for users logging into your product)?
• What email/productivity suite (Google Workspace or Microsoft 365) does your team currently use?

For a 50-person startup, I’d shortlist Okta, Microsoft Entra ID, and JumpCloud. The best choice depends mostly on what you already use.

My recommendation: Okta

For a startup that just wants easy, reliable SSO without committing to a larger IT platform, I'd pick Okta.

Its Starter suite is currently $6/user/month, includes SSO, MFA, Universal Directory and workflows, and Okta says it has 8,000+ pre-built integrations. That's particularly useful for a 50-person company where you don't want your IT person spending days configuring individual SaaS applications.

At 50 users, that's roughly $300/month ($3,600/year) at list price, although Okta has a $1,500 annual contract minimum.

When I'd choose something else

Already paying for Microsoft 365? → Microsoft Entra ID.
Entra ID P1 is currently around $6/user/month, and depending on your Microsoft licensing, you may already have the functionality you need. It's especially compelling if you're using Microsoft 365, Azure, or Windows heavily.

Want SSO + laptop/device management in one product? → JumpCloud.
JumpCloud is attractive for a small startup because it combines identity, SSO, MFA, directory services and device management. That can eliminate the need to buy/manage separate MDM infrastructure.

Already all-in on Google Workspace? → Google Cloud Identity.
Keeping Google as your identity provider is generally the simplest route rather than introducing another identity system solely for SSO.

What I'd do for a 50-person startup

If you're starting from scratch: Okta.
Microsoft 365: Entra ID.
Google Workspace + Macs/Windows and you want device management: JumpCloud.
Google Workspace and minimal IT complexity: stick with Google's identity capabilities.

One important distinction: if by "SSO provider" you mean adding login to your own SaaS product rather than SSO for your employees' applications, the answer changes substantially—Auth0, Clerk, WorkOS, and similar developer-focused providers would be the more relevant comparison.

For a startup with around 50 users, the "best" SSO provider depends on whether you mean internal workforce SSO (managing your team's access to Slack, Google Workspace, GitHub, etc.) or customer-facing B2B SaaS SSO (letting your customers log into your product via SAML).

The top, easy-to-setup options tailored for a 50-person startup are broken down below by use case:

• JumpCloud (Best for Internal Workforce & Device Management)
  • Best for: Managing your 50 employees, their laptops (Mac/Windows/Linux), and all internal cloud apps.
  • Why it’s great for startups: It acts as a cloud-based directory (a lightweight alternative to Active Directory). It's straightforward to set up, includes multi-factor authentication (MFA), and handles device management so you can secure company laptops without enterprise bloat.
  • Pricing: Very friendly for small teams, scaling per user/month. Learn more at JumpCloud.
• Google Workspace or Microsoft Entra ID (Best if you already use them)
  • Best for: Out-of-the-box internal SSO using the ecosystem you likely already pay for.
  • Why it’s great for startups: If your 50 employees use Google Workspace or Microsoft 365, you already have an identity provider. You can use Google/Microsoft as your core IdP to enforce MFA and single sign-on into third-party apps (like Notion, Figma, or GitHub) without adding a new vendor or paying for extra software.
  • Pricing: Included in standard business tiers. Explore options via Microsoft Entra ID or Google Workspace.
• WorkOS (Best if you are building B2B SaaS and need "Enterprise-Ready" login for your customers)
  • Best for: Adding SAML/OIDC enterprise SSO and SCIM provisioning to a product you are building.
  • Why it’s great for startups: If you're selling your software to larger companies that demand SSO, WorkOS makes you "enterprise-ready" in hours instead of weeks. It has incredible developer ergonomics, clean APIs, and features a self-serve Admin Portal that lets your B2B customers configure their own SSO without bugging your engineering team.
  • Pricing: Generous free tier for core user management, with modular pricing for active enterprise connections. Check it out at WorkOS.
• Clerk (Best for greenfield React/Next.js web apps)
  • Best for: Rapidly prototyping or launching a modern web app where you want authentication handled instantly.
  • Why it’s great for startups: If your team is writing a modern web app and wants drop-in UI components for user management, social logins, and basic authentication, Clerk takes minutes to drop into a codebase. (Note: Advanced enterprise SAML SSO requires jumping to higher tiers, but it's unmatched for early velocity).
  • Pricing: Free tier for early-stage apps. Learn more at Clerk.

To help narrow this down, let me know:

• Are you looking for internal SSO for your team to access workplace tools, or customer-facing SSO for a product you are building?
• What tech stack or productivity suite (Google Workspace, Microsoft 365, React, etc.) are you currently anchored to?

For a 50-person startup, I’d pick Clerk if you mean SSO/authentication for your own product. It’s probably the easiest developer experience of the mainstream options right now.

My shortlist

Clerk is particularly attractive if you're building a SaaS product: its Pro plan is $20/month when billed annually and includes one enterprise connection; additional SAML/OIDC connections are $75/month each. It also provides prebuilt authentication UI and organization/B2B functionality.

WorkOS is my choice if your startup's customers are going to demand things like SAML SSO, SCIM provisioning, directory sync, and enterprise admin workflows. Its SSO pricing is per customer connection, currently $125/month for the first 1–15 connections, with volume discounts.

So, in one sentence:

Building a startup product and want the least hassle? → Clerk.
Selling B2B and expect enterprise SSO requirements? → WorkOS.

If you tell me whether you mean SSO for your 50 employees or SSO that your SaaS customers will use, I can narrow it down to one provider.

For a 50-person startup, I’d shortlist JumpCloud, Microsoft Entra ID, and Okta. The best choice depends mostly on what you already use.

*Published/list pricing varies by plan and billing; verify before purchasing. Current comparisons put JumpCloud's entry SSO around $3/user/month, while Entra P1 and Okta's comparable entry offerings are around $6/user/month.

My pick: JumpCloud

For a 50-person startup starting from scratch, I'd lean toward JumpCloud. It combines SSO, MFA, user directory, provisioning, and device management, so you can avoid stitching several tools together. It's particularly attractive if you're a mixed Mac/Windows environment.

When I'd choose something else

• Already paying for Microsoft 365 Business Premium? Use Microsoft Entra ID. Business Premium includes Entra ID P1, making it hard to justify another identity provider.
• Expect lots of enterprise customers/compliance requirements? I'd choose Okta. It's more expensive/complex, but has an excellent ecosystem and a strong path as your company grows.
• Building SSO into the product you sell to customers? That's a different problem. I'd look at WorkOS rather than a workforce IdP. WorkOS is specifically designed to let a SaaS product accept SSO from its customers' identity providers.

Bottom line: For ~50 employees, JumpCloud for simplicity, Entra if you're already Microsoft-heavy, Okta if you're optimizing for enterprise/security maturity.

If you tell me whether you're Google Workspace or Microsoft 365, and whether your team is mostly Mac or Windows, I can narrow it down to one.

For a startup with around 50 users, the best single sign-on (SSO) provider depends entirely on whether you are managing internal employee access (Workforce SSO) or adding enterprise login for customers using your product (B2B SaaS / Customer SSO).

Scenario A: Managing Internal Employees (Workforce SSO & IT)

If you need your 50 team members to securely log into tools like Google Workspace, Slack, GitHub, and AWS, you want a lightweight cloud directory and identity platform.

• JumpCloud : Best overall for small startups. It acts as a unified cloud directory that handles SSO, multi-factor authentication (MFA), and basic device/laptop management (MDM). It is intuitive, straightforward to set up, and much less complex (and cheaper) than heavy enterprise tools.
• Google Workspace / Microsoft Entra ID : If you already use Google Workspace or Microsoft 365 for your business email, you might already have your SSO provider . Both allow you to configure SAML/OIDC apps and enforce MFA out of the box for your 50 users without paying for a separate third-party identity provider.

Scenario B: Adding Enterprise Login to Your Software (Customer/B2B SaaS SSO)

If you are building a B2B product and your enterprise clients are demanding SAML/OIDC login (Okta, Azure AD integration), you don't want a workforce tool—you want a developer-first API layer.

• WorkOS : Purpose-built for B2B SaaS startups. It lets you plug in enterprise SSO (SAML, OIDC) and directory sync via a single, clean API without rewriting your core authentication. It includes a self-serve admin portal so your customers can configure their own SSO connections.
• Clerk or Auth0 (by Okta) : Great if you need a comprehensive user management and authentication system from day one. Auth0 offers deep extensibility, while Clerk provides an exceptionally fast developer experience for modern web frameworks.

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

• Are you setting this up for internal team members (employees accessing internal apps) or customers logging into your SaaS application?
• What identity or productivity tools (like Google Workspace, GitHub, or AWS) are you already using?
