Built by a couple.

Ambit didn't begin as a product. It began with a couple realizing their tools were failing them.

He was a former banker. He'd built a budgeting spreadsheet in Excel — formulas nested four deep, a tab structure that made sense only if you'd watched it evolve. It grew across decades, accumulating new accounts, new bills, the inevitable surprises. Eventually it became a franken-spreadsheet even its author couldn't extend without breaking something.

She kept her budget in a notebook. By choice. Every month she sat down with a pen and wrote out what came in and what went out and what the family owed itself in savings. The act of writing it by hand was the point — slower, deliberate, harder to ignore than a screen. It worked beautifully for the budgeting she was doing.

But she'd started wanting more. Cross-account balance projections. Bill forecasts that updated as money moved. Savings goals that tracked themselves. The notebook couldn't do those things — and the more she described what she wanted, the more they realized the spreadsheet couldn't either.

When they sat down together to fix it, the conclusion was obvious: they needed a real app. But the apps they found all came with the same trade. Hand over your bank credentials to a third party. Pay a subscription forever. Accept that your financial data lives on someone else's servers, indexed for advertising. Both of them decided that was a step too far.

So they built one themselves. He wrote the code. She shaped the design and the priorities — what to forecast, what to surface first, what to leave out. They built it for the way they actually live, without any of the surveillance — and only then asked whether other people might want the same thing.
