“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
