Patrick Collison

Background

Patrick Collison (born September 9, 1988) is an Irish-American entrepreneur and the co-founder and CEO of Stripe, the payments infrastructure company he started with his brother John Collison in 2010 ¹². He grew up in the village of Dromineer in County Tipperary, Ireland, and began learning computer programming at age ten ¹. He won the 41st Young Scientist and Technology Exhibition in Ireland in 2005 at age sixteen ¹.

Collison attended MIT to study mathematics but dropped out to pursue entrepreneurship ¹². Before Stripe, he co-founded Auctomatic, an e-commerce platform that was acquired by Live Current Media in 2008 ¹. In 2010, Collison co-founded Stripe, which received early investment from PayPal co-founders Elon Musk and Peter Thiel, and from Sequoia Capital, Andreessen Horowitz, and SV Angel ¹. Stripe’s mission, as Collison describes it, is “to grow the GDP of the internet” ³.

Beyond Stripe, Collison co-founded the Arc Institute in 2021, a nonprofit biomedical research organization ⁴. In 2020, he co-founded Fast Grants with economist Tyler Cowen, distributing over $200 million to accelerate COVID-19 research ⁴. He also co-founded the intellectual movement Progress Studies with Cowen in 2019 ⁵. In April 2025, Collison joined Meta’s board of directors ⁶.

As an angel investor, Collison has made approximately 50+ investments across a portfolio of 30+ companies, focusing on foundational technology and infrastructure rather than consumer applications ⁷⁸.

Stated Thesis

(Self-reported: These represent what Collison says publicly about his investing approach. See Inferred Thesis for analysis of actual investment behavior.)

Collison has not published a formal investment thesis, but his investing approach can be inferred from public statements and his Stripe experience:

• Infrastructure compounds: Collison and his brother consistently back companies building foundational technology that other businesses depend on, believing that infrastructure investments compound in value as more businesses build on top of them ⁴.

• Developer-first, global, and long-term: Their portfolio thesis is described as “developer-first, global, and long-term: fund platforms that unlock new business models and compound over decades” ⁴.

• Product over marketing: Collison has stated that among startups he has observed, “the vast majority of overperformers focused almost to the exclusion of PR and marketing on product in the early days, while the bottom-performing companies almost all got distracted by PR and marketing, particularly in the first year or two” ⁴.

• Progress and scientific advancement: Collison has publicly stated: “I don’t understand why everyone isn’t obsessed with this. Are we on track for the flying cars or not? And if we’re not, what can we do to fix it?” ⁹. His investments in Arc Institute, Fast Grants, Pacific Fusion, and Terraform Industries reflect a deep interest in accelerating scientific and technological progress.

Inferred Thesis

The analysis below is based on 22 verified angel investments where Patrick Collison’s participation could be confirmed through press coverage, company announcements, or investor database listings. This represents a partial view—various sources report his total investments at 50+ deals.

Sector distribution (19 verified investments with confirmed sector data): - Developer tools / software infrastructure: 7 of 19 (37%) — Retool, Cortex, Linear, Anysphere (Cursor), Antithesis, Crosby, PostHog - AI / machine learning: 2 of 19 (11%) — Cognition, Conjecture - Climate / energy / deep tech: 3 of 19 (16%) — Pacific Fusion, Terraform Industries, MatX - Robotics / hardware: 3 of 19 (16%) — Matic, Rain, The Bot Company - Fintech / business software: 3 of 19 (16%) — Gusto, Airtable, Slack - Talent / venture platforms: 1 of 19 (5%) — Entrepreneurs First

Note: Each company is counted once in its primary category. Companies spanning multiple categories (e.g., Anysphere spans dev tools and AI) are placed in the category that best represents the product.

Stage distribution: Collison invests across stages, from seed (Gusto seed, Terraform Industries seed) to Series A (Retool Series A, Airtable Series A, Linear Series A) to later stages (Slack Series C, Entrepreneurs First Series C, Cortex Series C). The portfolio skews early-stage but includes opportunistic later-stage positions in high-conviction companies.

Geographic patterns: Predominantly US-based (San Francisco Bay Area), with some UK/European exposure (Entrepreneurs First in London, Conjecture in UK).

Key patterns: - Deep infrastructure bias: Roughly a third of verified investments are developer tools and software infrastructure companies, consistent with Collison’s Stripe experience building developer-facing infrastructure. - Frontier technology appetite: Investments in nuclear fusion (Pacific Fusion), autonomous drones (Rain), home robotics (Matic), synthetic fuels (Terraform Industries), and AI research (Cognition, Conjecture) show willingness to back deep-tech companies with long time horizons. - Co-investment with brother John: Many investments appear to be made jointly with John Collison; press coverage frequently references “the Collison brothers” rather than attributing investments individually ¹⁰¹¹. - No board seats taken: As a full-time CEO of Stripe, Collison does not appear to take board seats at portfolio companies (with the exception of Arc Institute and Pacific Fusion, which he co-founded or co-leads).

What Founders Say

No independently sourced founder testimonials specific to Patrick Collison’s role as an angel investor found. The “Collison installation” is a widely cited Y Combinator concept referring to the aggressive early-user-acquisition technique the Collison brothers used at Stripe, but this relates to their work as founders rather than as investors ¹⁶.
