Tools and SaaS built to ship — by senior engineers.
Internal tools, dashboards, MVPs and full SaaS products engineered with modern stacks, type safety and a bias for outcomes.
Overview
We're a senior product engineering team that ships. From 8-week MVPs to multi-year platform builds — TypeScript, modern infra, and a process honed across 180+ launches.
The problem
You probably came here because…
These are the patterns we see across the teams that engage us — and the ones we fix in the first 90 days.
- 01MVPs that take a year to ship
- 02Internal tools held together with spreadsheets
- 03Tech debt blocking every new feature
- 04Hiring a founding engineer takes 6+ months
- 05AI features stuck in 'eternal prototype'
Outcomes
What changes after working with us.
Ship fast, ship well
MVPs in 8–12 weeks without the tech debt that kills v2.

Type safety, tests, CI/CD, observability — not a hackathon prototype.
Modern stack
TypeScript, React, Postgres, edge runtimes, and the AI/LLM stack done right.
Owned by your team
Clean code, docs and handover — so your team can extend without us.
Results & impact
Numbers our clients see, not vanity charts.
What's included

System design, data model, infra and security decided before code ships.

Launch & Hand Off
Production rollout, docs, runbooks and optional ongoing support.
Industries
Teams we know how to grow.
Why Tenvix
Senior operators. Skin in the game.
We earn trust the same way you do — by shipping outcomes, week after week. No juniors disguised as strategists, no rebadged decks, no surprises in the invoice.
Senior-only delivery
Every engagement is led by an operator with 10+ years in their craft.
Outcome-aligned
We scope to measurable KPIs and report against them weekly.
Transparent process
Shared Linear board, weekly demos, async updates — no black box.
Bias for shipping
We optimize for what's live this week, not what looks great in a deck.
FAQ
Answers before you ask.
What stack do you build on?+
TypeScript-first. React/Next.js/TanStack, Node, Postgres, Supabase, Vercel and Cloudflare are our defaults. We adapt when projects require it.
Do you do AI / LLM work?+
Yes. RAG, agents, evals and shipping LLM features into production — including the unsexy work of latency, cost and guardrails.
Will we own the code?+
Always. Repo, infra accounts and IP transfer to you from day one.
Can you work with our existing team?+
Yes — augmentation, embedded or fully outsourced. We've done all three.
