About
Cornerstone is Will Lammers and Ben Thompson. We started it in 2026 to give people their time back. We’re forward-deployed software engineers: we work inside a business, in any industry, and build the custom software and AI that take the busywork off its people.
You’ll work directly with Will and Ben. The people in your first meeting are the people doing the work, and we’ll come to you to see how it runs.
Co-founder, engineering
Before Cornerstone, Will was a forward-deployed engineer inside Fortune 500 companies, some of North America’s largest retailers and manufacturers. He built automation and internal tools for their operations, including the ones that pay bills and collect what’s owed. He leads our engineering and builds our custom AI.
Co-founder, finance
Ben builds full-stack, from the database to the screen. He trained in finance and accounting and leads our finance work: the books, payroll and the monthly close.
Our meetings and email go into our own company brain, and AI keeps the record current. Nothing about money or people changes without one of us, and every change can be undone.
We use it every day, from our phones and inside the AI tools we work in.
The first visit is free, and you’ll leave it knowing what we’d start with.
The code, your data and the accounts are in your name, with plain-English notes any good developer or bookkeeper could pick up. All we keep is the know-how.
It’s the two of us. If that ever changes, you’ll hear it from us first.
We come from forward-deployed engineering, building automation and internal tools inside the operations of some of North America’s largest retailers and manufacturers. A growing business has the same kind of complexity, with people, customers and real money moving through it, and usually no software team of its own. We bring one, in person.
A cornerstone is the first stone set in a building’s foundation. Every stone after it is laid in line with it. That’s the job we want to do for a business: the first piece you set, the one the rest of the work lines up with.
There’s a second reason for the name: our business has a cornerstone too.
Christ Jesus himself being the cornerstone.
