Building at Unicorn Scale: Fresha CTO on Data, AI and Developer Velocity

Chris Greeno, CTO at Fresha, joins Andy Davis to discuss how Fresha approaches real-time data streaming, engineering productivity, AI adoption, Claude in practice, and what it takes to build technology at serious scale.Chris shares a practical view of what it takes to scale technology inside a high-growth product business, covering Fresha’s approach to near real-time data streaming, architecture decisions, cost trade-offs, and the move from traditional reporting infrastructure towards more responsive data products.The conversation also explores how AI is changing software engineering. Chris discusses Fresha’s adoption of tools like Claude, Cursor and other AI coding assistants, why developer adoption is often harder than expected, and how engineering leaders need to rethink productivity, safety, observability and platform tooling in an AI-enabled environment.A particularly strong theme is mindset. Rather than seeing AI as a threat to engineering craft, Chris argues that engineers need to learn how to express their craft differently moving from writing every line of code themselves to guiding, reviewing and orchestrating AI-enabled systems.
