Piton Labs

Build financial products with engineers who speak accounting.

Build your ledger, connect to your payment providers, or turn a flow of funds diagram into a working app. We’ll work with your finance and engineering teams to get the details right and ship a product your team can keep building.

A few of the teams we’ve worked with

When the numbers don’t add up

A payment succeeds, but the balance is wrong. A refund gets processed twice. Your finance team spends hours matching and reconciling records by hand. This is what makes Fintech hard.

Connecting an API is only part of the job. Your software modeled to understand each transaction, handle failures, and give your finance team a way to investigate what happened. That takes an understanding of both the business and the code.

The Piton Labs way

Work with engineers who can discuss the accounting with finance, the tech tradeoffs with engineering, and plan ahead what happens when things go wrong.

We’ve rebuilt a small-business loan application for Accion Opportunity Fund, worked on Twisp’s ledger platform, and integrated Twisp into ROH’s payment system. You get that experience on your project, from the first technical decisions through launch.

Get your financial product built and launched.

Work out the requirements together

You don’t need a finished specification. We’ll work with your product, engineering, and finance teams to understand the problem, resolve the open questions, and agree on what to build.

We speak engineering and finance

We can work with non-technical and technical team members alike to make sure your product is accounting for every dollar that flows through it.

Keep building with your own team

Your team gets the source code, documentation, and training to maintain the product. We can also help you hire engineers or keep working alongside you as the product grows.

Accion Opportunity Fund / Small-business lending

Loan applications and financial data platforms.

We re-architected, rebuilt, and launched AOF’s loan-application system, integrating with their existing loan origination and management systems.

Our work also included financial data platforms, Alloy KYC integration, and a variety of data feeds supporting AOF’s custom scorecard.

After the initial launch, AOF extended the engagement to keep building with Piton Labs.
