AI & LLM products
Practical AI features and agents, built on your data and measured before they ship.
- Copilots, search and chat over your own data
- Evaluation and guardrails, not vibes
- Model and vendor choices that age well
For ideas that earn a head tilt.
Head Tilt Labs is a small software studio. We help founders and teams turn promising ideas into AI products, web apps and MVPs — with senior judgment from first sketch to production.
01 — What we do
Four ways to work together.
Scoped to the problem: a two-week prototype, a quarter of building, or a standing seat at your table. Mix and match as you go.
02
Custom web apps
Fast, durable web applications, designed and engineered end to end.
- Product design through deployment
- Well-chosen, boring-in-a-good-way stacks
- Built for the team that inherits it
03
MVPs & rapid prototypes
From idea to clickable prototype in days, and to a working MVP in weeks.
- Clickable prototypes for users and investors
- Tightly scoped MVPs with a launch plan
- Learn fast, then decide what to build
04
Fractional CTO
Senior technical leadership on your schedule, without a full-time hire.
- Architecture, roadmap and build-vs-buy calls
- Hiring, vendors and team setup
- Due diligence and second opinions
02 — How we work
Small team. Short loops. No surprises.
The same rhythm whether it's a two-week prototype or a year of building.
01
Listen
We start with the problem, the people and the constraints — not the stack.
02
Prototype
Something you can click within days, so decisions get made on real things.
03
Build
Weekly releases and demos. You always know where things stand.
04
Hand off
Clean code, clear docs and a team ready to run it. Or we stay on.
03 — From the lab
Small things, built properly.
Two pieces running live on this page, written from scratch in plain JavaScript. No libraries, nothing sent anywhere. The owl at the top is watching too.
01
Fit the pieces
The owl is built from circles and tangent arcs. Drag each part into place, or press Assemble. The last piece is the tilt.
This piece needs JavaScript.
02
Watch it learn
A small neural network trains in your browser as you watch. Add points to the grid and it redraws its boundary. The score is measured on points it never trained on.
This piece needs JavaScript.
04 — About
Hi, I'm Sam.
I started Head Tilt Labs to work on the kind of ideas that make people lean in. I partner with founders and teams to scope, architect and build software that ships — and I stay close to the work from the first conversation to launch.
When you work with Head Tilt Labs, you work with me.
Sam Feder
CEO / Founder
