We typically reply within 1–2 business days. You're welcome to review our services, products, and open-source projects first, but sending the brief directly is the fastest path.

Common questions

How do engagements typically work?
Two models: one-off project builds with a fixed scope, or monthly retainer partnerships for ongoing product work. We'll recommend which fits after hearing what you need.
What's the typical timeline for a project?
Depends on scope. Small integrations ship in weeks; full product builds run 2–4 months. We scope before committing to a timeline so the estimate is real.
Do you work with early-stage teams?
Yes — startups through growth-stage companies. What matters is a clear problem and willingness to ship, not company size.
What tech stack do you use?
TypeScript and Swift are our defaults. We also work across Python, Rust, and C when the project calls for it. Stack decisions are driven by the problem, not preference.
What should I include in my first email?
What you're building (or fixing), your timeline, current stack if relevant, and any constraints. A few sentences is enough — we'll ask follow-ups.
