Loved by finance teams and founders

“I cancelled my accountants mid-project, paid them for their time, and started fresh with ClaimKit. It was still cheaper and faster than letting them finish.”
Kyel Steensma · COO, Edexia
“The R&D evidence finding was excellent. This addressed a massive pain point for us, and the ROI was very very good. Would recommend to anyone!”
Geraldine · CEO, Lewi Software
“Enjoyed every bit of using this, it is happy to work with raw data and we didn't need to write the report ourselves. It saved a lot of time compared to traditional consultants.”
Sayan · COO, Fluer
“Efficient, effective with an emphasis on details.”
Rizal Evans · CEO, Evimien

What you can claim

Much more than engineering salaries, with state credits on top of federal.

Engineering and Technician Wages

Plus the people directly supervising and supporting the work.

Prototype Materials and Supplies

Parts and materials consumed in R&D, reviewed invoice by invoice.

Contract R&D and Test Labs

65% of what you pay US contractors and labs.

Cloud and Simulation Computing

Compute for simulation, modeling and testing. AI tokens and infrastructure costs count too.

State R&D Credits

Typically 5–24%, and up to 30% in some states.
