B2B SaaS operator. Four exits. Growth-stage advisor, fractional executive and NED. Based in London.

Andrew Wyatt has spent thirty years building, running and selling B2B software companies. Four successful exits: Lotus to IBM ($3.5B), Paragon Software to Phone.com ($500M, European record exit on $10M revenues), Apertio to Nokia ($240M), and Clearswift to Lyceum Capital ($50M).
Most recently, Chief Growth Officer at Sapio Sciences and Sigmatic Sciences (GHO Capital), the life sciences informatics and AI platform. Before Sapio, Chief Operating Officer at Lumeon, the deterministic care-orchestration platform used at NYC Health + Hospitals, Kaiser Permanente, USC Keck, BUPA and Nuffield.
Ortent Advisory Ltd is the vehicle for the next stage. Advisory, fractional executive and board work with growth-stage life sciences and AI SaaS companies. Selective. Named engagements. Written outputs.
Every advisory engagement produces something written. Named deliverables. No slide theatre. Written outputs a board can act on. The audience is narrow: growth-stage B2B SaaS, life sciences informatics, digital health, and AI SaaS. Between £5m and £30m ARR, post-Series B or PE-backed.
Every advisory engagement produces something written. A Sprint delivers a board-ready answer to one question. A 90-day Diagnostic delivers twenty answered questions and a target operating model. Advisory produces working notes, board-pack reviews and quarterly summaries. Nothing lives only in someone's head after Andrew has left the room.
The work is grounded in what a growth-stage board actually needs. Not consulting frameworks that describe the problem. Working artefacts that resolve it. The five interactive diagnostics on this site are drawn directly from that operating experience. They are free because they are the thinking, not the engagement.
The audience is narrow. Growth-stage B2B SaaS. Life sciences informatics, digital health, and the AI SaaS companies serving both. Between £5m and £30m ARR, post-Series B, or PE-backed. This is where thirty years of pattern recognition lands the hardest.
The framework is public. The verdict is the work.

WeeklyBoard-facing commentary on growth-stage SaaS, life sciences and AI. Published on Substack and inside LinkedIn.
"The partner program Andrew built at Sapio set a new bar for what life sciences software ecosystems can look like. He made it easy for global services partners like Cognizant to invest, deliver, and grow alongside the platform, which is rarer than it should be."
