Fractional CTO
Senior technology leadership for a day or two a week, until you're ready for a full-time CTO, and then we'll help you hire one.
About us
Dyfiant is two senior technologists based in Cardiff, working as one small, experienced team.
Between us we've run engineering, operations and product at a telecoms business that grew from nothing to over 100 people and £150m turnover, serving 250 service providers from small operators to Vodafone, Sky Business and Deutsche Telekom. We've built data platforms for AI drug discovery and virtual hospital wards, and for the last few years we've run technology for a regulated investment platform.
That mix is the point. We're comfortable in the boardroom and in the codebase, and we know what changes when the system you're building carries emergency calls or other people's money. That includes AI: we use it where it earns its place, and we'll tell you plainly where it doesn't.
We take on a small amount of work at a time, so you always get us, not someone we've hired.
Our services
Most technology problems aren't really about technology. They're about how the platform, the team and the business fit together. We look at all three, tell you plainly what we see, and help you fix it, for as long as you need us and no longer.
Technical review
An independent, plain-English assessment of a platform, team or plan, in two to three weeks.
Platform engineering
Hands-on engineering for the hard parts: cloud platforms, delivery pipelines, data platforms and migrations.
