What SOSV SF & NY (Fka IndieBio) does
SOSV SF & NY (formerly IndieBio) is the deep tech venture capital arm of SOSV Investments LLC, founded in 1995 by Sean O'Sullivan. The firm operates three deeply resourced accelerator locations: SOSV SF (San Francisco, est. 2015) and SOSV NY (New York City, est. 2020), which together absorbed the legacy IndieBio biotech program, plus SOSV HAX (Newark, est. 2011, focused on hardware and physical sciences). Each location offers on-site wet labs (BSL1/BSL2), chemical and mechatronics labs, and embedded technical staff including location-specific CSOs and CTOs. As of early 2026, SOSV manages $1.5B in assets under management across funds, with Fund V ($306M) being the largest core vehicle.
The firm invests at pre-seed through Series A+, executing approximately 60 pre-seed deals of up to $550K per year and roughly 150 follow-on investments annually. Pre-seed founders join GP-led teams on-site for intensive product development, regulatory strategy, and fundraising preparation. SOSV's revenue model relies on standard venture capital mechanics: 2% management fees on committed capital plus carried interest on portfolio exits. SOSV also contributes 10% of firm profits to charity. The firm operates additional platforms including VC-Founder Matchups (15 events and 14,800+ 1:1 meetings since 2022), the annual Deep Tech Summit, the Deep Tech 100 portfolio showcase, the RETVRN exit preparation program, the new HAX Plasma Forge (plasma science startups at SRI Princeton), and the Genesis Consortium co-investment vehicle.
SOSV serves two primary customer segments: deep tech founders (scientists, engineers, and entrepreneurs in therapeutics, physical AI, climate tech, and advanced manufacturing) who receive capital, lab access, and operating support; and institutional limited partners (wealth platforms, sovereign wealth funds, corporates, family offices such as Credit Suisse, the Irish Strategic Investment Fund, Pfizer Ventures, and Honda) who provide fund capital. SOSV also supports 2,700+ co-investors through portfolio syndications. The portfolio spans 800+ companies that have collectively raised $7.3B and reached $18.2B in aggregate valuation, with 44% of founders holding PhDs and operations across 58 countries.

SOSV SF & NY (Fka IndieBio) competitors and assessment
Company assessmentDirect peers
- Y Combinator: The largest and most influential pre-seed/seed accelerator, running twice-yearly batches with standardized $500K checks. Directly comparable to SOSV as both operate batch-based accelerator programs targeting early-stage founders with global reach.
- Techstars: Global accelerator network running 50+ programs annually across verticals with mentor-driven cohorts. Closely comparable to SOSV's multi-location accelerator model (SOSV NY/SF/HAX), although Techstars lacks SOSV's deep lab infrastructure.
- Bolt (formerly Bolt.io hardware accelerator): Hardware-focused startup accelerator providing prototyping tools, mentorship, and seed capital. Directly comparable to SOSV HAX, which targets hardware founders with on-site labs and supply chain support.
- Plug and Play Tech Center: Silicon Valley-based accelerator and venture fund running industry-specific programs (health, fintech, retail, etc.) with corporate partnerships. Comparable to SOSV for running vertical-specific accelerator batches with corporate LP backing.
Broad incumbents
- Khosla Ventures: Established deep tech venture firm with significant biotech, climate, and frontier tech exposure. Comparable as a deep tech specialist but operates without SOSV's lab/infrastructure model and at much larger AUM scale.
- Andreessen Horowitz (a16z): Large multi-stage VC with dedicated bio/health and American Dynamism practices. Overlaps with SOSV in deep tech investing but does not run accelerator-style programs with on-site labs.
Emerging players
- Antler: Global pre-seed VC running residency programs across 25+ cities. Comparable to SOSV's pre-seed, GP-led team model but with lighter infrastructure footprint and broader stage range.
- Creative Destruction Lab: Science-based accelerator affiliated with top research universities, focused on commercializing academic research. Comparable to SOSV for science-founder focus and structured program model.
- Breakthrough Energy Ventures: Climate-tech-focused deep tech fund backed by Bill Gates and ultra-high-net-worth LPs. Comparable as a deep tech specialist targeting one of SOSV's core verticals (climate tech) but operates later stage with $1B+ check sizes.
- DCVC (Data Collective): Deep tech and computational sciences VC that has co-invested with SOSV in portfolio companies like unspun. Comparable for deep tech thesis focus and co-investment relationship, though stage and check size differ.
