Why we started Adaire.

A note from David Kemmerer, co-founder

Most tax firms still run the way they did twenty years ago. The software is old, the process is manual, and the client experience is an afterthought: a folder of PDFs, a flurry of emails in March, an invoice in April. The people inside those firms are often excellent. The systems around them are not.

I’ve spent the last ten years building consumer tax software at CoinLedger, a product more than a million people around the world use to make sense of their taxes. That work taught me what modern technology can do for a return: read every document, reconcile every number, catch what a tired pair of eyes would miss, and give the client a clear view of where things stand at any moment. It also left me genuinely shocked at how far behind the accounting profession has fallen in putting any of it to use.

Over time, that shock became frustration, and the frustration became a question. What would a tax firm look like if you built it today, from the ground up, around the capabilities that now exist? Not software bolted onto an old practice. A practice designed around the software, with AI, careful system design, and the engineering discipline of a modern technology company at its core, and with licensed tax professionals doing what only people can do: understanding your situation, exercising judgment, and signing their name to the result.

That question became Adaire.

Adaire is a technology-forward, AI-native tax preparation firm. We are building it to give the people who trust us with their returns an experience that is an order of magnitude better than what they’ve come to expect. Faster, clearer, more accurate, and more human, because the technology does the reading and the people do the thinking.

When I started down this path, I heard the same thing from accountants and partners who had been preparing returns for decades. “This is just how it’s always been done.”

Well, “how it’s always been done” isn’t good enough. Not for returns this complicated, not for clients this busy, and not when the tools to do it better already exist.

Welcome to Adaire. Modern tax, human expertise.
