Iterus is an AI-native software studio from Prague. We build production web and AI applications — Next.js, TypeScript, PostgreSQL/Supabase, Claude and OpenAI API integrations. Delivery is accelerated with Claude Code and Codex; quality is secured by human oversight, automated tests and independent code review.

Case studies
Iterus has no client references — everything here is our own product, which we scoped, built and paid for ourselves. Three products have a case study with the architecture, numbers from the repository and what the human did versus the AI — two live, one pre-launch; projects still in progress get one sentence about what they are built on.

Innea
Czech AI support between therapy sessions — text and voice chat, mood tracking and a crisis layer that points to the 116 123 helpline.

Innea Pro
Practice operations for Czech therapists on the same core as Innea — self-booking calendar, AI session notes, invoicing under Czech rules and health-insurer billing documents.

How we work
How do we work?
We work AI-native: delivery is accelerated with Claude Code and Codex, and quality is secured by automated tests, independent code review and specialists on demand.
Introductory call
A free 30-minute call — we cover the goal, the scope, and whether we're a good fit.
Discovery (optional)
A paid discovery for 25,000 CZK — scope, architecture and estimate. The fee is deducted from the price of the follow-up project.
Validation pilot
A working version in production: authentication, database, one or two integrations, tests, deployment. Takes 3-6 weeks.
Production version
Roles and permissions, payments, admin, more integrations, e2e tests, CI and monitoring. Takes 6-14 weeks.
Handover
The client owns 100% of the source code and documentation on payment — on a standard stack another team can pick up.
Iterus
Why “in loops”?
The name Iterus comes from iteration — a repeated step forward. Good software isn't a leap; it's a path walked in loops: build, test, listen, improve. Again. With AI tools, iterations are cheaper and faster than ever — we turn that into a method, and have given it a name.

Pricing
What does each band cost?
Custom development pricing: a validation pilot from 90,000 CZK, a production application from 250,000 CZK, AI integration and on-prem LLM from 180,000 CZK (on-premise from 350,000 because of hardware). All prices exclude VAT and scale with scope, not with estimated hours.
Idea validation
from 90,000 – 250,000 CZK
3–6 weeks
A working pilot in production: authentication, database, one or two integrations, tests, deployment.
Production application
from 250,000 – 700,000 CZK
6–14 weeks
Roles and permissions, payments, admin, multiple integrations, e2e tests, CI and monitoring.
AI integration and on-prem LLM
from 180,000 CZK
4–12 weeks
Connecting a model to company data, answer-quality controls and a transparency layer. On-premise deployment starts higher because of hardware and operations; hardware is not included.
