Hankin Associates,led by Sebastian Wilson. Twenty years of experience in some of the world's most complex organisations

Most advisors have observed complexity from a distance. Sebastian Wilson has operated inside it — across twenty years, at institutions like HSBC and Dixon Carphone, leading programmes that others were unwilling to commit to at the scale and pace they required. That is a different kind of counsel.

At HSBC, Sebastian authored the group's first AIOps strategy and led its largest IT transformation — a programme spanning multiple banking functions, 36,000 employees, and £1.5bn in identified savings. He also led the bank's multi-cloud strategy via Google Cloud Platform, producing templates that were adopted across the wider group.

He founded Hankin Associates after concluding that real impact requires senior-led, contingency-based engagement — not retainer theatre. The advisory model that followed is structured around that conviction: Sebastian leads every engagement personally, fees are tied to outcomes, and no junior is placed between client and counsel.

He continues to advise CEOs and MDs across mid-market financial services, retail, and PE-backed portfolio companies — bringing the same discipline to a single-engagement diagnostic as to a multi-year transformation programme.
