The problem with traditional agencies
Most software costs more after launch than before it. Every update needs a developer, knowledge leaves with people who quit, and the maintenance invoice grows every year. We design every project so that routine support (watching that everything works, installing updates, catching bugs early) is handled by AI, with a senior engineer accountable for the result.
What we build
- Web platforms & marketplaces: for rentals, bookings and business client portals.
- Subscription software (SaaS): from the first version to a growing base of paying customers.
- Internal tools & CRMs: replace spreadsheets and disconnected apps with one system.
- Integrations: connect your CRM, payments, accounting and messaging.
- Taking over existing products when your current vendor misses deadlines or has disappeared.

FAQ
How much does custom software development cost?
It depends on scope, integrations and timeline. We give you the price for a clearly defined first stage before we start, and it stays the same. See How pricing works.
Why are you cheaper than other agencies?
AI handles a large share of routine work, such as tests, documentation, monitoring and updates, so a small senior team delivers what usually takes a bigger one.
Can you take over a project another team started?
Yes. We start with a short review of what's already built, tell you honestly what's worth keeping, and take it from there.
Do you sign an NDA?
Yes, before the first detailed conversation.
