The team
Operators who have shipped financial products to real SMB customers
All four co-founders have direct experience building financial products for the SMB market — from restaurant-tech SaaS to fintech infrastructure to SMB lending at scale.
Four years as VP of Product at a restaurant management SaaS, where Devon watched 3,000 restaurant operators lose hours each week to manual reconciliation work. That direct exposure to the problem drove the founding of Mainstreetspine in 2023. Devon leads product strategy and platform partnerships.
Previously built fintech infrastructure at Stripe and Dwolla, where Yael designed and maintained payment routing systems processing millions of ACH transactions per month. At Mainstreetspine, Yael leads the treasury engine, banking API layer, and platform integrations architecture.
Background in SMB lending at Kabbage and American Express Business, where Kwame underwrite working capital products for small businesses using alternative data models. At Mainstreetspine, Kwame leads the credit engine, underwriting models, and risk framework for revenue-based merchant credit lines.
Spent a decade in strategic partnerships at vertical SaaS and marketplace companies, building channel programs that scaled to nine-figure GMV. At Mainstreetspine, Bridget leads design-partner acquisition, platform onboarding, and the revenue-share economics that align Mainstreetspine with its platform partners.
