“Can a tax-credit automation platform become the financial operating layer that systematically unlocks government money for startups and SMBs?”
MainStreet was founded in 2019 in San Jose, California, as a platform focused on helping startups and small businesses discover and claim tax credits (notably R&D credits) and government incentives. The company raised a Series A in 2021 led by SignalFire at a $440M pre-money valuation and has since grown to 101-250 employees. The embedded finance angle centers on integrating with payroll/HRIS systems (via Finch) to automate the data collection needed to substantiate tax credit claims, essentially turning a compliance workflow into an automated financial benefit for SMBs.
MainStreet is founded in 2019 and headquartered in San Jose, California, USA.
