The research happened. Now find the records.
An engineering team tests a new design, changes the software and records what failed. Months later, someone has to reconstruct that work for an R&D tax-credit claim.
The records are spread across code repositories, project tools, reports, payroll and accounting systems. ClaimKit gathers them into the claim as the work happens. [1]
ClaimKit is building an AI-native tax firm, starting with R&D credits. Its software collects and organizes the records; R&D tax specialists review the activities, costs and final claim. [1][2]
Build the file throughout the year
ClaimKit connects to engineering and business tools, including repositories, project-management systems, shared files and accounts. It finds records associated with the company’s research projects. [1]
Commits, tickets, test reports, purchase orders and payroll can then be organized around the relevant business components. Monthly collection keeps the file closer to the work the engineers actually did. [1]
The team can see which projects and costs are being considered while the supporting material stays attached. A specialist checks the research activities and expense eligibility before the claim is finalized. [1][2]
For US claims, ClaimKit prepares the R&D study and filing materials, including Form 6765 and relevant state forms. Audit support stays with the service. [1]
Keep the engineer close to the engineering
Consider a team developing a battery-management system. The technical story may sit across firmware changes, failed tests, component purchases and design notes.
ClaimKit can bring those records into the same project file. A technical lead can explain the uncertainty being worked through while the underlying tests and development history remain available for review. [1]
The tax specialist then assesses that work and the associated costs. The engineer supplies the technical facts without having to become the person rebuilding the entire tax file. [1][2]
Less reconstruction for the customer
At Fluer, COO Sayan highlighted the work ClaimKit took off the team’s hands: moving from raw data to a report without the company having to write it itself. [1]
Edexia COO Kyel Steensma brought ClaimKit in after changing accountants partway through a project. He found the service faster and less expensive, even after accounting for time already paid to the previous provider. [1]
Those experiences centre on the same job: collect the material, explain the research and prepare a claim without pulling the operating team into weeks of reconstruction. [1]
Tax experience meets engineering
Co-founder and CEO Rachel Huang worked as an R&D tax specialist at KPMG and has built companies herself. Co-founder and CTO William Mahon brings engineering experience from Google. [2][3]
The team pairs that software background with tax specialists responsible for review and sign-off. ClaimKit joined Y Combinator’s Fall 2026 batch. [2][3]
Its starting product is R&D tax credits, with services for US and Australian businesses. Companies can book a conversation to review their projects and the applicable process. [1][2]
The broader ambition is a tax firm where records stay connected to the business all year, instead of appearing for the first time at the filing deadline. [1][2]
Where ClaimKit ranks
ClaimKit isn't in a numbered ranking yet. Products get a position once enough companies compete on the same task.
Current rankings. Positions come from public evidence, and no company can pay for a place. How we rank
The bigger picture
R&D teams should be able to explain what they built and why the work was difficult. The supporting records should already be there. [1]
ClaimKit is building the software and specialist service that put those two parts of the claim together. [1][2]
