Helps startups and small businesses identify and claim R&D tax credits and government incentives using AI-driven technology MoreLess
MainStreet is a financial technology startup that operates in the business finance sector. The company specializes in identifying and claiming tax credits for businesses, leveraging artificial intelligence (AI) technology to streamline the process. MainStreet's primary clients are businesses of all sizes that are looking to maximize their savings through tax credits.
The company's business model revolves around using its proprietary AI technology to search through over 200 tax credits to find those that best suit a client's business. Once a business qualifies for certain tax credits, MainStreet takes over the process of claiming these credits, thereby saving the client time and effort. The company generates revenue by charging a fee for its services.
MainStreet's team of experts, which includes in-house Certified Public Accountants (CPAs), tax code specialists, and business founders, provides support throughout the tax credit claiming process. The company prides itself on its compliance with Internal Revenue Service (IRS) guidelines, ensuring that all tax credit claims are accurate.
The company has a strong track record, with none of the thousands of companies it has helped having been audited. MainStreet's services are designed to provide businesses with peace of mind, freeing them up to focus on building their businesses while MainStreet handles their tax credits.
