Hayden Simmons is the Founder and General Partner of Rally Cap, which he launched in 2020 to back global fintech founders at inception.

Prior to founding Rally Cap, Hayden spent over a decade operating at the forefront of emerging-market and cross-border fintech, with deep experience across payments, credit, and financial infrastructure. He held senior strategy and business development roles at Facebook’s Novi/Diem project, where he worked on global go-to-market strategy for a blockchain-based payments ecosystem, as well as at Juvo and Migo, where he helped scale inclusive financial products across Latin America, sub-Saharan Africa, and Southeast Asia. Earlier in his career, Hayden focused on remittances and payment transparency across the U.S.–Mexico and U.S.–Philippines corridors.

In addition to operating roles, Hayden has been deeply embedded in the venture ecosystem. He served as a Venture Partner at Lateral Capital, a pan-African fund, and advised IDEO’s Last Mile Money initiative, giving him sustained exposure to early-stage underwriting, founder support, and fintech adoption in high-growth markets.

Hayden’s investing perspective is grounded in lived experience. He studied Latin American Economic Development at Colorado College, where he wrote his thesis on collectivized remittances in Mexico, and is fluent in Spanish. This combination of operating depth, global market fluency, and early-stage investing experience underpins Rally Cap’s ability to identify non-obvious founders, underwrite conviction early, and build meaningful ownership in globally scalable fintech companies.

Born and raised in San Francisco, California, he enjoys rock climbing, trail running, playing guitar and tending to his mezcal farm. He lives with his wife Melissa and kids (Hayes, 4; Lucia, ~0; and Eddy, goldendoodle) in Marin County.
