9x Dev

One AI-native team for custom software, fractional CTO, applied AI and tech recruitment. Shipped in weeks.

Most agencies talk about AI. We build with it every day, and you can see it in the timeline. 9x Dev is one team spanning engineering, product, design and QA. You get the depth of a full department at the pace of a small one: four to eight people who own a product end to end, embedded with your team from day one, and handing over clean when we leave. What we do • Custom software: product platforms, internal tools and integrations, owned entirely by you. • Fractional CTO: technical leadership without the full-time hire, including the hard calls. • Applied AI: retrieval, agents and evaluations built to survive production. • AI transformation: changing how a company works, which takes more than buying licenses. • Legacy modernization: replacing a system without a big-bang cutover weekend. • Tech recruitment: engineers we'd hire ourselves. How we work • We release weekly. Tests, CI and observability are what make that calm. • Agents are in the loop for everything: code, tests, research, reporting. You're paying for judgment, not typing. • Handover starts in week one: documentation, runbooks and access, so your team can carry on without us.
