ClaimKit

Reconstructing a year of engineering work from memory, git logs and payroll is how many finance leads and CTOs prepare an R&D tax credit claim, and the founders of ClaimKit built their service to stop that. It captures the evidence while the work happens instead.

## Evidence gathered as work happens

Customers link repositories, project tools, Google Drive and accounting software. The company's AI ties activity to each business component and sorts the costs, and a specialist then checks every component and expense against the four-part test. The site's demo shows commits, tickets, test reports and purchase invoices matched to one component, and puts the customer's own time at around two hours a year.

## What a claim covers

The site lists engineering and technician wages, prototype materials and supplies, contract research and test labs at 65 percent of what is paid to US contractors, and cloud and simulation computing. State credits are typically 5 to 24 percent, up to 30 percent in some states. The output is Form 6765, the state credit and an R&D study for each component, and the company says it helps defend a claim if it is audited.

## Beyond the United States

The launch post notes that more than 70 governments reward R&D spending and says ClaimKit serves 80 or more clients in three countries, figures it states itself. The site shows a United States edition. Rachel, a former KPMG R&D tax specialist, started it with Will, a former Google engineer.

Not yet independently verified: No maker launch date, so it is dated from the Y Combinator launch listing. The 80 clients in three countries, the reviewer and founder backgrounds and the time estimate are the company's own; no pricing is published, and neither page gives its location or surnames. We will update this when it can be confirmed, and remove this note.
