Three senior engineers. No juniors. No outsourcing. Direct Slack. We design and ship production-grade web products for startups and scale-ups in the US.
Trusted by teams shipping to millions
Same three founders, end to end. No project managers translating between disciplines, no juniors learning on your dime.
Marketing sites that convert
Marketing teams stuck waiting on engineers. We ship visually-managed sites your team can update without breaking anything.
Series A–C startups, SaaS, agencies.
Every line is written by a senior engineer with 6+ years shipping production web software. No agency-style bait and switch after the SOW is signed.
You get a shared channel with the actual builders. Decisions in minutes, not next Tuesday's status call.
We optimize for momentum. You always see what's real, running, and deployed — never a Figma pretending to be progress.
We rebuild if it's off by 2px. Typography, spacing, motion — the details are the product, and we treat them that way.
LCP under 1.2s, CLS at 0, TTFB from the edge. Fast sites convert. Fast apps retain. We won't ship anything that isn't.
Maintenance, performance audits, feature work. Your codebase gets better every month, not slowly rots.
60-min call. We diagnose the real problem, not the requested feature.
Whiteboard your goals, users, and constraints. Leave with a shared understanding — no slide decks, no jargon.
Scope, stack, milestones. A one-page plan you can actually decide on.
We pick the smallest technology surface that can win. Signed scope, fixed timeline, no hidden change orders.
High-fidelity design in Figma. Motion prototypes for the important moments.
Pixel-perfect frames, real content, live prototypes. You approve motion before we write a line of code.
Two-week sprints. Live preview URL updated every push.
Direct Slack channel, GitHub PRs, and a preview URL that reflects what shipped 30 seconds ago.
Cross-browser, accessibility, performance. Real devices, not simulators.
Lighthouse budgets, axe accessibility, real iPhones and Androids. Ship a green scorecard, not a green checkbox.
Zero-downtime cutover. DNS, monitoring, analytics wired in.
Runbook, rollback plan, and an engineer on call for launch day. We hit publish together.
Monthly performance reviews. Iterate on what the data says.
We keep shipping. Weekly digest, monthly business review, quarterly roadmap — until you tell us to stop.
We don't chase frameworks. We use what compounds — proven runtimes, well-typed contracts, edge-first infrastructure. Your codebase should still make sense in three years.

“They shipped in four weeks what our previous agency couldn't finish in six months. And the code is actually good.”
No account managers, no juniors learning on your budget. The people you pitch are the people writing code, shaping brand, and answering at 11pm.
"Every engagement has one accountable human. That is the entire product."
Owns partnerships, scope, and delivery end-to-end. Runs discovery, keeps commitments honest, and answers on Slack before your coffee is cold.
