Otta's take on MainStreet

Theo Margolius headshot

Theo Margolius

COO of Otta

The US tax code is so complex that even many accountants are unable to fully identify and take advantage of the rebates and credits available to early stage technology businesses. These credits can be worth tens of thousands of dollars to even small businesses, so there's a strong incentive to seek them out.

MainStreet takes on this burden for businesses by connecting to startups’ payroll and scanning the data on a monthly basis for potential federal, state, and local tax credits. It then advances 80% of the credit due to the startup so it can use the funds right away, and charge a 20% commission fee for its time.

With more than half a million new startups being created every year, MainStreet certainly has a flourishing market at its fingertips. In recent years, local governments and states are looking to attract businesses to their specific region with rebates and incentives, making the market for a platform like MainStreet bigger than ever.

The founders are ex-Google employees and successful technology entrepreneurs themselves. Founder Doug Ludlow was motivated to start the company due to his experience growing up in a city greatly impacted by the decline of big business. If smaller businesses are able to flourish, he believes that communities can continue to thrive.
