Building and Owning Software is Hard

We’re Thunk, and we build world-class software products. We help our clients truly own their software — from brainstorm, to development, to real life.

We don't just build apps from scratch  — we can take legacy systems down to the studs to rebuild them right. As your software general contractor, we handle it all: planning, design, engineering, deployment, maintenance — even hiring your internal team when the time is right.

Add fuel to the fire

Launches and Relaunches

Start fresh or start over.
Whether you're launching something new or ripping out the old stuff, we handle the full build: planning, design, code, and deployment — done right, and designed to be inherited easily by whoever comes next.

Product Consulting

Get unstuck, get aligned.
Whether you're between PMs or just need a sharper strategy or smoother process, we bring clarity and momentum to your roadmap and your team.

Devs for Hire

Plug us in. Get shipping.
Our engineers drop into your team and start pushing code fast — we're really good at providing value on day one, and when we're done you don't have a dev team to pay every month.

Thunk People

Our team is our differentiator. Everyone at Thunk is product-minded, communication-focused, and results-driven.

Don’t Just Take Our Word For It

We’ve made some great friends along the way. Here’s what they have to say about us.

Product Management

"John has been instrumental in helping us rethink and improve our software development processes. He's fantastic about asking the right questions, and has pushed us to throw away rituals that never really worked for us and truly commit to the ones that do."

Chris Morrell

CEO @ InterNACHI

Flexible Dev Team

"Working with the team at Thunk has been game changing for us. As a small bootstrapped company we don't have the same resources as our VC backed competitors, but having Thunk in our corner has allowed us to scale up our MVP at a speed we'd never achieve on our own.

We are excited to continue our relationship with Thunk and the flexible development resources they provide as we scale our company."

Jade Null

CEO @ GlitchSecure

A Strong Reputation

"I’ve worked with Daniel Coulbourne for almost a decade, and he’s a master of thinking deeply about difficult problems and coming up with creative solutions. Every project Daniel is on is a bit more fun and a lot more likely to succeed.

I don’t have a decade with him, but John Drexler is a hard working guy with a lot of fresh ideas. All in all, I love these guys."
