Rent an engineer for $399/mo. Satisfied or refunded.
Symbai is an AI startup building the agent stack that lets one senior engineer ship like a team. You rent that engineer for one flat monthly price, write what you need in plain words, and get it back done. No hiring, no meetings.
No job ads, no interviews, no waiting. Rent one senior engineer backed by Symbai's AI agents, for one flat price, working on your stuff this week.
Get StartedEverything, in one thread
Every request, update, and progress note lives in one conversation. Nothing gets lost, nothing needs a meeting.
No limits on what you ask
Bug fixes, new features, updates, big cleanups. Anything you'd hand an engineer. No counting tasks.
Work is performed by senior engineers using AI tooling. Scope, pace, and outcomes vary per engagement. Cancel anytime.
Customer support, daily chores, internal tools. Describe the job and you get a working agent, not a framework. Symbai builds it, hosts it, and tunes it every week, with a human reviewing everything it does. Flat monthly per agent. The first ones are already live.
Coming Soon
Not a 24/7 pager. Not a junior on-call. A senior engineer in your Slack channel inside an hour, for the three things that need it this week — launch days, things breaking, urgent moves. Enable Flash the month you need it, drop it the month you don't.
Coming Soon
You know the shape of the work, the deadline, and the ceiling you'd pay. We agree on all three, do the work, and get out — no retainer, no ongoing overhead. If the work doesn't match what we agreed, half comes back.
Coming Soon
Your engineer, backed by a second A-player review, answers questions about your tools, your setup, and day-to-day choices—so you have the guidance you need to build safely and grow.
We'd rather show you the offer than invent a crowd: a senior engineer in your inbox this week, a flat price, and a refund if you're not satisfied. The first public case studies go here as clients allow it — until then, judge us by the terms we put in writing.
