Upwork is a marketplace: you post a job, compare proposals and manage whoever you pick. It works well for small, well-defined tasks. For an AI assistant, voice agent, data pipeline or MVP, the hard part is scoping and production quality, and that is where marketplace projects most often stall. Kortex Labs scopes it with you, quotes one fixed price within 24 hours, and ships it with tests, monitoring and a handover.

When the marketplace is the better choice

If you already have a technical lead, a clear backlog and need extra hands for months, hiring by the hour is simpler. We will tell you that on the first call.

When a fixed-price studio is the better choice

What we've shipped

20+ products in production, including a pipeline that turned 2,046 search queries across 27 countries into one queryable dataset and a voice-first platform where clinical notes write themselves. Read the case studies or estimate your project with the cost calculator.

Frequently asked questions

Is Kortex Labs cheaper than hiring a freelancer?

Not always per hour. It is predictable: one fixed price for the finished system, so overruns are our problem, not yours.

How fast can you start?

A fixed-scope quote within 24 hours of the first call; build slots usually open within one to two weeks.

Who owns the code?

You do. 100% of the source and IP transfers on delivery, with documentation and a deployment runbook.

Can I start small?

Yes. A 5-day prototype on your own data costs $1,000 and is credited in full if you go ahead with the build.
