Mica Creek Capital
Mica Creek Capital is the Collison family office deploying Stripe wealth into venture and growth-stage technology companies from San Francisco.
Mica Creek Capital
Mica Creek Capital emerged from the wealth generated by Stripe, the payments infrastructure company co-founded by Patrick and John Collison in 2010. The firm is named after a creek in the brothers' native Ireland, signaling its ties to the Collison family rather than a generic institutional brand. It functions as the family's primary investment vehicle, managing capital for the Collisons and a circle of early Stripe executives who accumulated significant wealth as the company's valuation rose past $95 billion at its peak. The firm invests across early-stage venture, growth equity, and liquid crypto markets, with a preference for developer-tooling, fintech infrastructure, and climate-adjacent software. Public record shows Mica Creek has backed companies including Ramp, the corporate card and spend-management platform, and remote-work tool Deel, both of which share Stripe's DNA in payments and global compliance. The office also makes fund commitments to venture firms with overlapping theses, and has been an active direct participant in Series B through D rounds where Stripe itself is a commercial partner. Mica Creek maintains a lean structure, consistent with the operational philosophy of its founders. The team includes dedicated investment professionals drawn from the Stripe ecosystem, with a dual mandate to preserve purchasing power for the principals while backing frontier technology. The firm does not publish headcount or deployment figures, but its check sizes in known deals range from $10 million to $75 million, placing it in the middle-weight tier of tech family offices. The structural differentiator is proximity: Mica Creek's principals built Stripe's global payments network, giving the office a proprietary lens on which fintech and enterprise-software startups have genuine product-market fit. This operator-turned-investor edge—combined with the Collisons' direct relationships across Y Combinator and the venture ecosystem—produces a sourcing funnel that conventional allocators cannot replicate.
