I need to find the most active angel investor groups in the Bay Area that focus on healthtech.

• Band of Angels - 750 Battery St 7th Floor, San Francisco, CA 94111, United States
• Bay Angels - 80 Liberty Ship Wy, Sausalito, CA 94965, United States
• Launchpad Digital Health - 1275 Mission St, San Francisco, CA 94103, United States
• Versant Ventures - 1 Sansome St #3630, San Francisco, CA 94104, United States
• Rock Health - 333 Bush St, San Francisco, CA 94104, United States
• Bay City Capital - 750 Battery St #400, San Francisco, CA 94111, United States
• DigiTx Partners - 2000 Sierra Point Pkwy, Brisbane, CA 94005, United States
• Pear VC - Pear Studio SF - 600 Townsend St, San Francisco, CA 94103, United States
• 5AM Ventures - 4 Embarcadero Ctr Ste 3110, San Francisco, CA 94111, United States
• Questa Capital - 501 2nd St #615, San Francisco, CA 94107, United States
• Founders Fund - 1 Letterman Dr Bldg D, 5th Floor, San Francisco, CA 94129, United States
• LVP Life Science Ventures (fka Latterel Venture Partners) - 455 Market St #2220, San Francisco, CA 94105, United States

If by “most active” you mean a combination of current deal activity, Bay Area presence, healthtech specialization, and ability to lead or syndicate early rounds, I’d start with these:

My recommendation by startup type

• Digital health / healthcare SaaS / AI: HealthTech Capital → Healthcare Angels → Keiretsu → Bay Angels
• Medical device / diagnostics: Life Science Angels → Keiretsu → Band of Angels
• Biotech / therapeutics: Life Science Angels → specialist life-science syndicates
• AI + healthcare: HealthTech Capital → Band of Angels → Bay Angels → Keiretsu

LSA is particularly compelling for very early companies: it says its historical initial investments have ranged from $100K to $1.1M, with many deals syndicated to raise $3M+. It also explicitly covers digital health, computational methods, AI, devices, diagnostics, genomics and biopharma.

One under-the-radar channel

Medical Mondays is worth knowing about even though it isn't a conventional Bay Area angel group. It describes itself as a network of 80+ healthcare angel groups, VC funds, hospitals and incubators, and continues to run healthcare pitch events in 2026. It could be useful for getting a specialist investor introduction or building a syndicate.

If you're actually fundraising, I can take this one step further and build you a top-10 Bay Area healthtech investor target list with typical check size, stage, specific healthtech focus, recent investments, application/contact route, and whether they prefer warm introductions.

Here are the most prominent and active angel investor groups and networks in the San Francisco Bay Area that focus heavily on healthtech, biotech, and medical devices:

• Life Science Angels (LSA) : Based directly in the SF Bay Area, Life Science Angels is arguably the premier angel group dedicated exclusively to biotech, medical devices, diagnostics, and digital health/healthtech. They feature over 130 accredited investors, have deployed more than $60 million into 100+ early-stage companies, and syndicate cleanly into a single line on your cap table.
• Healthcare Angels : Operating out of San Francisco and Silicon Valley, Healthcare Angels specifically targets technology-enabled healthcare products, digital health, and services that meaningfully improve cost, access, and quality of care. They source and syndicate deals directly through targeted investor portals and local incubator networks.
• Bay Angels : As one of Silicon Valley's longest-standing angel networks, Bay Angels invests broadly across early-stage, scalable sectors—and their membership pool includes a high concentration of seasoned medical, biotech, and tech executives who routinely evaluate and back digital health innovations.
• Astia Angels : While Astia Angels operates globally with a local Bay Area presence, they stand out for investing exclusively in high-growth startups that feature women in executive leadership, maintaining a strong portfolio footprint in healthcare and life sciences.

(Note: While traditional venture capital firms like Khosla Ventures or a16z Bio + Health also dominate the Bay Area healthtech seed landscape, the groups above operate specifically as collaborative angel networks where individual accredited investors pool capital and review pitches collectively.)

Would you like information on how to pitch these specific groups , or are you looking for individual prominent healthtech angel investors who write checks in the Bay Area?

If by “most active” you mean a combination of current deal flow, healthtech specialization, Bay Area presence, and ability to write/syndicate angel checks, I’d prioritize these groups:

1. Life Science Angels — strongest specialist

This would be my first target for most healthcare startups. LSA is Bay Area-based, has 130–150 accredited investors, and invests exclusively in life sciences. It reports 100+ early-stage investments and more than $60M deployed. Its scope includes healthcare discovery and delivery, making it relevant across biotech, medtech, diagnostics and digital health.

Best if: you have meaningful clinical/scientific differentiation, regulatory complexity, medical devices, diagnostics, or healthcare IP.

2. HealthTech Capital

Probably the closest match if “healthtech” means digital health rather than biotech. I'd put it ahead of the generalist groups for healthcare SaaS, AI-enabled care, healthcare IT, and technology-enabled services.

Best if: you're building digital health, healthcare AI, workflow/IT, care delivery, or a tech-enabled healthcare business.

3. Healthcare Angels

A healthcare-specialist network worth pursuing alongside LSA and HealthTech Capital, particularly where clinical and healthcare-industry expertise is important.

Best if: you need investors who can help with healthcare commercialization, clinical relationships, and industry introductions.

4. Band of Angels

This is the strongest broader angel network I'd add. Band has 150+ angels, reviews 1,000+ deals annually, and invested in 15 startups in 2025. Importantly for you, it explicitly invests in healthcare/life sciences and has a dedicated Life Science & MedTech SIG; its calendar currently shows that group meeting regularly.

Best if: your healthtech has a strong software, AI, hardware, or other technology component and you want experienced Silicon Valley operators.

5. Sand Hill Angels

I'd put this on the list particularly for AI/software-heavy healthtech. It's less healthcare-specialized than LSA or HealthTech Capital, but its Silicon Valley technology network can be valuable for companies where the technology platform is a major part of the investment thesis.

6. Bay Angels

A useful broader network. Bay Angels says it has 75+ active members, has reviewed 3,000+ pitch decks, and in 2025 one in four presenting companies at its live pitch events received an investment. It explicitly accepts Healthcare/Biotech as a sector.

How I'd prioritize them

Digital health / healthcare SaaS / AI:

1. HealthTech Capital
2. Healthcare Angels
3. Life Science Angels
4. Band of Angels
5. Sand Hill Angels
6. Bay Angels

Medtech / diagnostics / regulated healthcare:

1. Life Science Angels
2. Healthcare Angels
3. HealthTech Capital
4. Band of Angels
5. Sand Hill Angels

Biotech / therapeutics:

1. Life Science Angels
2. Healthcare Angels
3. Band of Angels
4. Specialized life-science syndicates

One interesting additional channel is Angel Launch: its Bay Area community says it attracts 400+ startups and accredited investors each month and specifically runs Medtech/Healthtech events. That's more of a deal-flow/networking channel than a traditional angel group, but it could be useful for introductions.

If you're actually raising a round now, I can take this one step further and build you a ranked list of 15–20 Bay Area healthtech angels/groups with individual investor names, recent healthtech investments, typical check sizes, stage, and how to get an introduction.

3. Healthcare Angels

A healthcare-specialist network worth pursuing alongside LSA and HealthTech Capital, particularly where clinical and healthcare-industry expertise is important.

Best if: you need investors who can help with healthcare commercialization, clinical relationships, and industry introductions.

4. Band of Angels

This is the strongest broader angel network I'd add. Band has 150+ angels, reviews 1,000+ deals annually, and invested in 15 startups in 2025. Importantly for you, it explicitly invests in healthcare/life sciences and has a dedicated Life Science & MedTech SIG; its calendar currently shows that group meeting regularly.

Best if: your healthtech has a strong software, AI, hardware, or other technology component and you want experienced Silicon Valley operators.

5. Sand Hill Angels

I'd put this on the list particularly for AI/software-heavy healthtech. It's less healthcare-specialized than LSA or HealthTech Capital, but its Silicon Valley technology network can be valuable for companies where the technology platform is a major part of the investment thesis.

6. Bay Angels

A useful broader network. Bay Angels says it has 75+ active members, has reviewed 3,000+ pitch decks, and in 2025 one in four presenting companies at its live pitch events received an investment. It explicitly accepts Healthcare/Biotech as a sector.

When targeting the San Francisco Bay Area for healthtech, digital health, and life science angel investments, you are looking at an ecosystem where traditional angel groups often blur lines with early-stage micro-VCs and specialized syndicates.

The most prominent and active angel groups, networks, and prominent micro-funds focusing on healthtech in the Bay Area include:

• Life Science Angels (LSA) : Based in the Bay Area, this is arguably the premier nonprofit angel group specifically dedicated to funding early-stage biotech, medical devices, and digital health/healthtech companies. They frequently co-invest with institutional funds and provide robust mentorship. You can explore their criteria on the Life Science Angels Site.
• Sand Hill Angels : A very active, prominent Silicon Valley-based angel group comprising experienced executives and entrepreneurs. While sector-agnostic, they heavily evaluate and invest in life sciences, medical devices, and healthcare IT/digital health deals alongside enterprise tech. More information is available via Sand Hill Angels.
• Band of Angels : Based in Silicon Valley, this is one of the oldest and most established angel organizations in the country. A substantial portion of their membership consists of former high-tech executives and physicians who actively review and fund medical tech, diagnostics, and digital health startups. Check details on the Band of Angels Website.
• Golden Seeds : Though national in scope, Golden Seeds has a very active California/Bay Area chapter. They focus on women-led enterprises and frequently back innovative healthcare, life sciences, and healthtech companies. Learn more through Golden Seeds.
• Precursor Ventures (Charles Hudson) : Operating heavily at the pre-seed and seed stage in the Bay Area, Charles Hudson and his team frequently write initial checks ($250K–$1M) into digital health and software-driven health platforms. Review their thesis via Precursor Ventures.
• Rock Health : While not a traditional angel group, Rock Health is a specialized early-stage fund and coalition based in SF explicitly dedicated to digital health. They act as an anchor in the Bay Area healthtech community and syndicate heavily with individual angels and micro-VCs. See their community and portfolio on Rock Health.

If you'd like to narrow this down, let me know:

• What funding stage are you at (pre-seed, seed, or bridge)?
• Is your healthtech focus pure software/digital health or does it involve hardware/biotech/devices?

I can tailor this list to match your exact profile and funding goals.

The San Francisco Bay Area hosts several prominent, highly active angel investor networks and groups that specialize in or frequently deploy capital into healthtech, digital health, and life sciences.

Top Angel Groups & Networks in the Bay Area (Healthtech Focus)

• • Focus: Exclusively life sciences and healthcare, spanning digital health, healthtech, medical devices, diagnostics, and biopharma.
  • Overview: Headquartered in Sunnyvale/Bay Area, LSA is widely recognized as one of the premier healthcare angel groups in the U.S. Its members include experienced executives, clinicians, scientists, and serial entrepreneurs who provide domain-specific due diligence and mentorship alongside capital. Typical initial investments range from $200k to $600k, with syndications going higher.
• HealthTech Capital (Active via regional syndication)
  • Focus: The specific intersection of healthcare and information technology (capital-efficient healthtech, mHealth, wearables, and care-delivery platforms).
  • Overview: Based in the Silicon Valley/Los Altos Hills area, this group was explicitly formed to fund innovations that improve efficiency in healthcare delivery (distinct from heavy legacy IT or pure biotech). They often co-invest alongside other regional networks like Sand Hill Angels.
• • Focus: Disruptive and scalable technologies across AI, SaaS, deeptech, and health systems/digital health.

  • Overview: One of Silicon Valley's oldest continuously active angel groups. Operating on a flexible, relationship-driven model where members invest independently or syndicate locally rather than through a single blind pool.

If you'd like, I can help you:

• Tailor your pitch deck structure for healthtech angel groups
• Detail the typical check sizes and stage preferences for a specific group above
• Identify individual super-angels active in Bay Area digital health

Let me know how you'd like to proceed with your outreach.

I searched for Bay Area angel investor groups with a healthtech focus. The strongest matches are a mix of healthcare-specialist angel networks and larger Silicon Valley angel groups that frequently invest in healthtech.

My shortlist by startup type

Digital health / AI healthcare / SaaS for providers

1. HealthTech Capital
2. Healthcare Angels
3. Sand Hill Angels
4. Band of Angels

Medical devices / diagnostics

1. Life Science Angels
2. Angels4Health
3. Keiretsu Forum

Biotech / therapeutics

1. Life Science Angels
2. Keiretsu Forum
3. Other life-science syndicates (often accessed through specialist networks)

Additional channels worth knowing

• Medical Mondays is not a single Bay Area angel group, but it is a healthcare funding network connecting startups with dozens of angel groups, venture funds, hospitals, and incubators. It can be useful for syndication and introductions.
• For very early companies, getting one healthcare-domain angel champion first can be more valuable than approaching the largest generalist angel networks.

If you share your stage (pre-seed/seed/Series A), healthtech category (AI, device, biotech, digital health, diagnostics), and target check size, I can narrow this to the 5–10 groups most likely to invest.

If you mean angel groups/networks rather than traditional VC funds, I’d prioritize these Bay Area organizations for healthtech in 2026:

My top 3

1. Life Science Angels — probably the strongest first target if you're genuinely in healthtech. LSA is based in the San Francisco Bay Area, invests exclusively in life sciences, has 130–150 accredited members, and says it has invested in 100+ early-stage companies.

2. HealthTech Capital — particularly attractive if you're building digital health, healthcare AI, healthcare IT, or a tech-enabled clinical/business model rather than a therapeutics company. It's one of the more directly relevant healthcare-investor networks in Silicon Valley.

3. Band of Angels — worth targeting if your company has a strong technology component. The Band says it focuses primarily on seed-stage high-tech and life-science companies, reviews 50+ deals per month, and has a dedicated Life Science & MedTech SIG.

The Band is especially interesting from an activity/deal-flow standpoint: it has 150+ members and says it invests in 20+ startups annually, with healthcare/life sciences among its investment areas.

One important distinction

I'd separate "healthtech-focused" from "active angels who will consider healthtech." LSA and HealthTech Capital are much more specialized. Band of Angels, Sand Hill Angels, and Bay Angels are broader networks where your pitch needs to compete with startups from other technology sectors.

If you tell me (1) what you're building—digital health, AI, medtech, biotech, diagnostics, etc., (2) your stage, and (3) how much you're raising, I can rank 10–15 Bay Area angel groups and individual angels, including recent investments, typical check sizes, and the best way to get an introduction.

The San Francisco Bay Area features a dense concentration of angel networks, syndicates, and micro-VCs that focus heavily on digital health, medical devices, and healthtech.

The most active and prominent angel groups and early-stage networks in the region supporting healthtech include:

• Life Science Angels (LSA) , available at Life Science Angels , is one of the premier angel groups in the Bay Area specifically focused on early-stage life sciences. They actively invest in biotech/therapeutics, diagnostics, medical devices, and digital health/healthtech. Their membership includes experienced investors, clinicians, scientists, and industry executives who offer operational mentorship alongside capital.
• HealthTech Capital , based in Los Altos, is an angel investor group dedicated exclusively to transforming healthcare through technology. They focus on seed and early-stage investments in IT, digital health, and tech-enabled healthcare services, frequently partnering with regional medical centers and strategic health networks.
• Band of Angels , based in Silicon Valley/San Francisco, is one of the oldest and most recognized angel groups in the world. While generalized in tech, a significant portion of their members specialize in life sciences, medical technology, and healthtech through their dedicated life science/healthcare screening streams.
• Sand Hill Angels , based in Mountain View, is an active group of accredited investors funding early-stage startups. They frequently co-invest in digital health and healthtech infrastructure alongside software and deep tech, providing mentorship and hands-on guidance through early funding milestones.
• Berkeley Angel Network , accessible via Berkeley Angel Network , comprises alumni, faculty, and former staff of UC Berkeley. They frequently evaluate and fund early-stage science, biotech, and healthtech ventures spawned from the regional academic and medical ecosystem.
• Keiretsu Forum (Northern California) , listed at Keiretsu Forum , is a massive global angel network with a heavy footprint in the Bay Area. While sector-agnostic, their Northern California chapter sees frequent healthtech and life science deal flows and syndicates angel funding rounds efficiently.

If you'd like to narrow this down, please tell me:

• What funding stage are you targeting (Pre-seed, Seed, or Series A)?
• Is your product pure software/digital health or does it involve hardware/devices?

I can help you tailor your pitch strategy or identify specific micro-VCs that pair well with these groups.

The San Francisco Bay Area features several prominent, highly active angel investor networks and groups that specifically focus on or frequently deploy capital into healthtech, digital health, and life sciences.

• Life Science Angels (LSA) - Operating out of the Bay Area, Life Science Angels is one of the premier angel groups in the U.S. focused exclusively on healthcare. Their sweet spot is seed and early-stage funding across digital health, AI in healthcare, medical devices, diagnostics, biopharma, and genomics. Members include experienced operators, clinicians, and scientists who prefer taking an active advisory or board role.
• HealthTech Capital - Based in Silicon Valley, HealthTech Capital is an angel network vertically focused on healthcare innovation, spanning IT, digital health, and tech-enabled services. A notable percentage of their angel investors are innovative physicians and industry experts who provide both capital and direct corporate/clinical access.
• Sand Hill Angels - While generalist in nature, Sand Hill Angels (based in Silicon Valley) is exceptionally active in early-stage seed and Series A rounds. They frequently back disruptive and scalable technologies, which regularly includes digital health and healthtech platforms alongside enterprise software and deep tech.
• Band of Angels - As one of Silicon Valley's oldest and most established organized high-tech angel groups, the Band of Angels comprises over 150 current and former tech executives. While broadly focused on cutting-edge technology, their historical portfolio includes major healthcare IT and digital health plays (such as Practice Fusion) via members who look for deep-tech scalability.
• Bay Angels - Operating as one of Silicon Valley's active community-driven angel groups, Bay Angels brings together former founders and tech veterans who invest individually or syndicate checks into early-stage ventures, including emerging digital health and software innovations.

Could you share the stage of your company (pre-seed vs. seed) and specific sub-sector (e.g., digital health, medical device, AI diagnostics) so I can help you tailor your pitch approach to the right group?

If you’re looking for Bay Area angel investor groups that are active in healthtech, I’d prioritize groups with (1) healthcare domain expertise, (2) early-stage check-writing, and (3) strong syndication networks. The strongest candidates are:

My suggested outreach order by startup type

A few additional ecosystems worth tapping for introductions:

• Rock Health — not a traditional angel group, but a major digital health ecosystem connector.
• Bay Area LifeTech — a networking community connecting biotech, medical device, healthcare, and investor communities.

If you’re raising a pre-seed/seed round, I would generally start with Life Science Angels + HealthTech Capital + Healthcare Angels, then use the broader groups for syndication.

I can also put together a ranked list of specific angel investors (individuals) in the Bay Area who invest in healthtech, which is often more effective than approaching groups cold.
