Built by one person. On purpose.
Kynth is a one-person product company run by Isaiah Kim, a staff software engineer in New York. Every product here is a live AI agent doing real work in production — not a waitlist, not a prototype.
Who's building this
Isaiah Kim — staff software engineer, eight years in, based in New York. Before Kynth: sole web engineer for SS&C's Private Markets division, where an AI-assisted code generation system he designed compressed 12+ months of work into 2–3 across 2,000+ of SS&C's clients. Before that, uscis.gov.
How one person ships all this
One shared design system (100+ typed components), one multi-tenant production spine — one Stripe account, one signed webhook router, row-level security enforced at the database — and a capability layer where every app calls the same email, payments, and AI rails. The catalog is the output; the platform is the work.
Whose money is behind it
Nobody's. Kynth is 100%-owned and independent — no investors, no growth targets that end with your data being the product. Products stay up because people pay for them, which is the most honest incentive structure software can have.
Where the AI sits
The AI layer runs on Claude, with per-task model routing. It drafts, ranks, chases, and reconciles — and in anything high-stakes, you review and approve before anything leaves the building. Your data is never used to train models.
