Taihill Venture Research
Investment Thesis
Taihill Venture is a Boston-area, industry-agnostic pre-seed deeptech fund. Its stated mission is to pioneer breakthrough technologies that tackle longstanding challenges, and to empower scientific founders to turn research into tangible, real-world products. The firm describes itself as a bridge between top universities, frontier research labs and the scientists working in them, and the industrial and commercial world that needs their technology. Its pitch to founders is early support: resources, mentorship and help incubating ideas into viable businesses before founders realize they are ready.
Sector Focus
Although the firm calls itself industry-agnostic, the portfolio clusters heavily in science-driven categories:
- Biotech and life sciences tools and therapeutics (Concerto Bio, Immusoft, Signet Therapeutics, Proteowise, Valitor, Sylvatica Biotech, Acrobat Genomics)
- AI for drug discovery and materials (XtalPi, Deep Principle, Galixir, Kebotix)
- Semiconductors, photonics and hardware (Lightelligence, Finwave Semiconductor, Pointcloud, ChEmpower)
- Robotics, autonomy and advanced manufacturing (Bot Auto, Cyberdontics, Pantheon, Relativity Space)
- Synthetic biology and advanced materials (Modern Synthesis, Manus Bio, SanaHeal, Anthology, Kula Bio)
- A secondary cluster of fintech/payments and consumer companies, many with a China-North America bridge (Citcon, SnapPay, Snaplii, EasyTransfer, WeTravel, WeBox, Velotric)
Stage Focus
Pre-seed is the stated focus. Third-party data shows the firm also participating in later rounds as a co-investor, for example Series A rounds in Deep Principle (Nov 2025) and Collov AI (Apr 2026), and a seed round in Fortitude Biomedicines (Jan 2026).
Check Size
The firm does not publish check sizes. Its $20M fund (closed July 2023) implies small pre-seed checks. No check size range is recorded here because none is sourced.
Lead Tendency
Caplight lists the firm as a co-investor on every recent round it tracks. The firm publishes no lead-investor claims, so lead tendency is recorded as follows: more often a participant or co-investor than a lead, but not conclusively.
Recent Activity
- April 2026: Collov AI (Series A, co-investor per Caplight; CB Insights lists a Series B)
- January 2026: Fortitude Biomedicines (Seed, co-investor)
- November 2025: Deep Principle (Series A, co-investor)
- October 2025: Cookiy AI (Pre-Seed, co-investor)
- September 2025: AheadForm (VC round, co-investor)
- November 2023: announced a $20M fund, closed July 2023 after a first close in July 2022
The firm appears to be actively investing.
Portfolio Highlights
The firm says it has invested in over 130 startups across 3 funds since its 2017 inception; the website lists about 49 companies. Notable names include Lightelligence and XtalPi (both described by the team as unicorns), Relativity Space, Databento, Bot Auto, UniUni, Axoft and Finwave Semiconductor. Revela is described by the team as a 10x exit within two years.

Decision Process
Not published. The founding trio of Tianyi Yu, Hongkai He and Jingjing Chai are described as the general partners who started the firm after managing a family office for early-stage investments, which suggests a partnership model. This is an inference.
Founder Preferences
The firm backs scientific founders, typically academic or lab-origin technologists, and says it invests in people as much as in technology. It emphasizes early hands-on support before a company is formally ready to raise.
Geographic Focus
Based in Cambridge, MA (35 Willard St), with a strong US footprint in Boston-area science and a visible China-North America network across its team and portfolio (XtalPi, Deep Principle, Citcon, SnapPay, UniUni in Canada). No explicit geographic restriction is stated.
