The decisions a full-time CTO would own, at the time you can give it. ### Technical roadmap What to build, in what order, and what to leave out for now. ### Architecture decisions System design choices made and written down, so the team is not guessing. ### AI and Web3 calls Whether AI or blockchain fits a feature at all, and how much autonomy it should have. ### Build versus buy Custom development compared with existing tools before money is committed. ### Team and hiring Roles defined, candidates assessed and engineering practices set. ### Vendor and agency oversight Proposals reviewed, estimates challenged and delivery checked against what was agreed. ### Security and compliance Access, data handling and audit trails planned in, not patched on. ### Investor and board support Clear technical answers for due diligence, board updates and fundraising. ### Handover to a full-time CTO Documentation and context ready for the person you hire next. ## Delivered work behind our advice.

Leadership from people who ship. ### Honest, not sales-driven We will say "do not build this yet" when that is the accurate read. ### Grounded in delivered work Advice informed by AI and Web3 systems we have shipped, not theory. ### A team behind the role One senior lead, with engineers across AI, Web3 and software to draw on when a question needs depth. ### AI and Web3 under one roof One team that can compare both, rather than favouring the one it sells. ### Clear written output Every engagement ends with a recommendation you can act on or hand over. ### No lock-in The roadmap, documents and decisions are yours. You can hire a full-time CTO or another partner at any point. ## Engagement models. Pick the shape that fits where you are. Part-time leadership ### A set number of days each month Ongoing technical ownership for a founder or small team. Interim CTO ### Until you hire Cover between CTOs, plus help hiring and handing over to the next one. Leadership with delivery ### Advice and a team A fractional CTO plus a project-based or dedicated team to build what the roadmap calls for. ## What our clients say.

A senior technology leader who works with you part time, owning the technical roadmap, architecture and engineering decisions without being a full-time employee. ### When does a fractional CTO make sense? When you need senior technical judgement but not a full-time executive yet: before a first build, between CTOs, while managing an outside agency, or ahead of fundraising. ### How much time does a fractional CTO spend with us? It depends on what is waiting. We agree a monthly allocation up front and adjust it as the company changes. ### Do we have to build with you? No. The fractional CTO can oversee your own team or another agency. If you want us to build as well, that is a separate delivery engagement. ### Can you help us hire a full-time CTO? Yes. We can help define the role, assess candidates and hand over the roadmap and documentation. ## Ready to turn your vision into reality? Tell us where the company is and what decisions are waiting. We'll tell you honestly whether a fractional CTO is the right fit.
