The traditional agency model was built for a world where every line of code cost human hours. That world ended in 2024. Here's what changed — and where AI still needs a human to finish the job.
Traditional Agency — 9 months, $150k+

AI gets you 80%. A senior gets you shipped.
We won't pretend otherwise. Modern AI codegen is astonishing — it can produce a working prototype from a paragraph of intent in minutes. That's the 80%. The last 20% is where projects live or die: authentication edge cases, race conditions, data integrity, permission models, the specific quirks of your industry that no LLM has been trained on.
That 20% is what our seniors do. It's why our fixed price includes real human review, not just a prompt-and-pray pipeline. And it's why we're honest that RAD isn't a silver bullet — it's a leverage multiplier for experienced hands.
- ×Enterprise applications serving 10,000+ concurrent users with hard SLA requirements.
- ×Highly regulated systems requiring formal verification (medical devices, avionics, nuclear).
- ×Novel research problems where the solution itself is the unknown.
- ×Projects requiring 100+ dev-months of custom logic across many teams.
If any of the above describes your project, we'll tell you in the Discovery Sprint and refund you the $500.
