Infinity Systems

Infinity Systems builds custom AI-powered software for US and EU companies at a fixed price and a fixed date.

A senior engineer owns every project from the first call to production. AI coding agents do the volume, and specialists join when a job needs them. You get one price, one date and the scope in plain language before any work starts.

Three fixed-price tiers:

Feature Sprint, $10,000 to $25,000, 2 to 4 weeks: one AI feature, workflow automation or internal tool, in production.

Product Sprint, $25,000 to $50,000, 4 to 8 weeks: a full MVP with several roles, payments, admin and one or two AI workflows.

Platform Sprint, $50,000 to $100,000, 8 to 12 weeks: a multi-tenant platform or legacy replacement with several AI workflows and data migration.

Guarantees: the price is the price. Stop after the first weekly demo and pay only the deposit. Repository, cloud and model accounts are in your name from day one.

Infinity Systems LLC is registered in Wyoming, USA. Engineering is done in Serbia on Central European Time, with a daily overlap with US Eastern mornings.
