AI Software Studio · Delray Beach, FL

We build software that
builds itself

Zontak LLC designs AI-powered tools that turn ideas into deployed web applications — autonomously, affordably, and fast.

Pricing

Fixed scope, fixed price

Every engagement starts with a Discovery Sprint, then ships in one of four build tiers. Real source code on Cloudflare — yours to keep, modify, or migrate.

Start here · Tier 0 3–5 days

Discovery Sprint

$2,500
