01 The founder

Nikola Radošević, founder of Catapult

Principal engineer · Belgrade

Nikola Radošević

Founder, Catapult

LinkedIn

Your product is built by a former CTO — not sold by a senior and handed to a junior team.

Fourteen years across two extremes of software: government-grade security systems where mistakes aren't an option, and startup products where speed decides everything. AI agents multiply the output — the judgment, architecture, and accountability stay with one person.

CTO & board member

Led engineering across a fintech / blockchain portfolio for a Bloomberg-listed group. Bloomberg profile

Tech lead

Podcast-studio booking platform — grown to hundreds of paying studios.

02 The record

Seven products. One builder. All real, most live.

Every entry has a full case study — the problem, the build, and what shipped.

03 The protocol

Three steps. One accountable founder.

01

Scope in writing.

Day 0 · free

Send the problem, users, and must-have workflow — the 60-second estimator gives you feasibility, stack, and a price band. Then you get a written scope and a fixed quote.

02

Build in your accounts.

Day 1 → launch

Code lands in your GitHub from day one. Infrastructure and data stay under your ownership. Daily proof of progress — a link, not a status report.

03

Launch and hand off.

Handoff + warranty

Live URL, tests, setup docs, a recorded walkthrough, and post-launch support with a defect warranty. The clock starts once scope and access are confirmed.

04 The edge

Direct, not bureaucratic. Fast, not rushed.

I

Senior judgment. AI-native speed.

No project managers, no handoffs, no sales-to-delivery gap. The founder who scopes your product architects and ships it — with an AI-native delivery engine multiplying the output.

II

Gov-grade engineering habits.

A background in national security systems — ePassports, HSM-backed signatures — shows up in every build: tenant isolation, audit trails, review gates, and tested deploys. Even on a 24-hour MVP.

III

You own everything.

Code lands in your GitHub. Infrastructure and data stay in your accounts. Documentation and a recorded walkthrough on handoff — no lock-in, no dependency on Catapult to keep running.

05 The terms

Fixed price. Fixed timeline. No surprises.

Every engagement is a fixed quote, scoped to your product — from 24-hour launches to multi-week builds, plus audits and fractional-CTO work. Once scope is signed off the number is final: if the estimate runs over, Catapult absorbs the overrun. Full source in your GitHub, deployment, docs, and a recorded handoff are always included.

06 Questions

Asked before every launch.

Not seeing yours? Ask directly.

Yes — for tightly-scoped products: one user type, one critical workflow. Larger MVPs ship in a fixed week; complex products in 2–4 weeks. The free 60-second estimator tells you upfront which one your idea is. No surprises after we start.

07 The launch window is open

Your product, live this week.

No sales handoff — Nikola personally reviews every request and tells you whether it fits a 24-hour launch, a one-week MVP, or a bigger build. Fixed price, full source in your GitHub.
