Stellation Capital Research
Investment Thesis
Stellation Capital, founded in 2021 by Peter Boyce II, is a solo GP fund dedicated to co-leading first-check investments behind "philomath founders" building mission-critical software. The firm believes that intellectually voracious founding teams with deep domain expertise are best positioned to solve complex problems in software. Stellation's name—derived from the Latin root meaning "extending the boundaries of an original shape, producing a new, star-like figure"—reflects their approach of extending the reach of visionary founders through access to top-notch networks, community, and capital.
Stage and Check Size
Stellation invests as early as possible, with a primary focus on seed-stage investments:
- Check Size Range: $250K - $4M
- Sweet Spot: ~$1M
- Stage Focus: Pre-seed and seed (co-leads first checks)
- Lead Tendency: Typically leads or co-leads first institutional rounds
The firm deployed from their debut fund (Fund I, $40M, 2021) and has made 24 total investments with 16+ on record.

Founder Profile & Preferences
Stellation's portfolio reveals strong preferences:
-
Intellectual Rigor: The firm explicitly targets "philomath founders"—lovers of learning and intellectual pursuits. Portfolio companies feature founders from top universities (MIT, Harvard, Oxford) and research institutions.
-
Diverse Backgrounds: Portfolio includes women founders, founder teams from underrepresented backgrounds, and co-founder models emphasizing complementary skills.
-
Domain Expertise: Founders typically have deep technical or operational background in their domain—e.g., computer vision PhDs building vision AI, Apple alumni building computing experiences, fintech experts with institutional experience.
-
Mission-Driven: Portfolio includes founders focused on social impact (Block Party's Tracy Chou on harassment prevention, climate tech, family operations).
-
First-Institutional Round: Stellation explicitly co-leads "first checks," suggesting they seek founder teams at inflection point—product working, some early traction, but pre-institutional funding.
