Harry Clancy.
Founder.
AI engineer and consultant. Anthropic-certified. Runs every halcroft audit, scope, and build personally — no junior team, no offshore implementation pool.
He spent his early career as an AI engineer and consultant inside a growth consultancy, building the systems most of the market still talks about hypothetically. A lead intelligence pipeline that took 15 hours of manual screening out of one company's week, lifted qualified leads 3×, and pushed conversion rates up 20%. Multi-source marketing dashboards for €1m+ businesses, consolidating channels that previously lived across spreadsheets. The work paid for itself inside the first quarter.
Where halcroft started
Halcroft started where the patterns sharpened. Two early engagements made the case obvious — a UK accountancy practice and a US business broker. Different industries, same problem shape: fee-earners and partners losing hours to admin that didn't need a qualified human.
At the accountancy, the highest-impact workflow was the year-end document chase. In three weeks halcroft shipped a system that handed the firm 18 fee-earner hours a week, lifted on-time client submissions from 62% to 88%, and recovered £15,500 of billable advisory capacity in the first cycle alone.

Meanwhile the market was full of vendors selling those same partners GPT-wrapped chat boxes that broke within a month. Most AI consultancies aren't consultancies. They're prompt wrappers with a sales pipeline, and the work doesn't survive contact with real operations. That's the gap halcroft was built to fill.
Anthropic-certified — currently the only AI lab whose certifications carry weight — and invited to closed AI industry events. Harry runs every halcroft engagement personally. There is no junior team, no offshore implementation pool. The audit you book is the audit he delivers. The system he scopes is the system he ships.
