AI-Native Software Development vs Traditional Software House

Why a solo Fractional CTO + AI ships in days what a traditional software house ships in months — at one-tenth of the price.

A traditional software house multiplies billable hours: a business analyst runs discovery, a CTO makes the technology calls, a product owner carries the vision, and a four-to-eight-person dev team writes the code. Each role has its own rate, its own calendar and its own interpretation of the problem. The final project lands at 200,000–500,000 PLN and stretches across months.

AI-Native Software Development inverts this model: a single senior with 20 years of experience holds all the roles (BA, CTO, PO) while the latest LLM coding tools (Claude Code, Codex CLI) generate production code under supervision. Cost drops by an order of magnitude while quality stays production-grade.

Below is a head-to-head comparison of the two models across seven dimensions: time, cost, roles, code ownership, stack, evolvability, risk.

Often licensed / vendor lock-in
100% yours, no royalties, no SaaS lock-in
Tech stack
Whatever the team picks, sometimes exotic
Next.js + TypeScript + Supabase — thousands of devs on the market
Security
Depends on the senior in the squad
Security by design, RLS, deps audit, Playwright
Post-launch
Mandatory maintenance retainer with the house
Optional support, hand off to any team you want

What you actually get

Pricing is public. You pay for actual work time, not for billable hours of a team you never see.
