10,000 Days Capital Management

Tom Ryder and Megan Ryder serve as the decision-makers for the firm. Tom Ryder brings decades of operating and board experience from companies including Amazon, where he spent 17 years, and American Express. Megan Ryder, his daughter and partner, runs much of the day-to-day investing activity. The structure keeps the investment committee deliberately small and family-run, avoiding the consensus-building friction common to larger venture firms.

The structural differentiator is its rejection of a fixed fund life. By branding as a capital management company rather than a standard venture partnership, it can hold assets across decades rather than being forced to return capital to limited partners within a typical 10-year window. The father-daughter partnership between Tom and Megan Ryder also creates a built-in succession plan that most venture firms lack.

Tom Ryder's operating career spans a 17-year tenure at Amazon during its formative e-commerce and cloud infrastructure years, followed by board roles at American Express, Spotify, and Affirm. This network — combining enterprise sales, platform infrastructure, and regulated financial services — directly informs the firm's sourcing and diligence in enterprise and fintech software.

Yes, 10,000 Days frequently co-invests alongside larger institutional venture firms. Its participation in Modern Treasury rounds involved co-investors such as Benchmark and Altimeter Capital, while Anvil attracted participation from Gradient Ventures. The firm tends to take pro-rata follow-on rights and occasionally leads or co-leads seed rounds.
