Documented cause
MainStreet automated the discovery and filing of government tax credits and incentives for small businesses — R&D credits, hiring credits, state-level incentives — that most SMBs left unclaimed due to complexity. Despite genuine utility and $60M raised including from a16z, the company struggled to build a sustainable revenue model around a one-time or infrequent transaction. It shut down operations in 2023 after failing to reach profitability.
Lesson
“Transaction frequency is the hidden variable in fintech business models. A product used once a year at tax time is a services firm, not a SaaS platform — and cannot be valued or funded like one.”
