After 18 years in technical recruitment and hundreds of placements into defense programs, Sam Harrison built the verification engine the industry was missing.
18 years in technical recruitment. London to New York to Miami — from boutique agencies to building and scaling teams as Managing Director at Sourcechain.
People often ask me what the secret sauce of recruiting is. After nearly two decades, I realised it's an innate human skill — built up from thousands of micro-decisions, gut reactions, and pattern recognition. At its core, it's a chemical reaction: is this person telling me the real story?
I was deliberating with a CTO friend about why we always seemed to be on the same page about the right hires. We'd both developed this instinct independently — him from the engineering side, me from the recruiting side. We just knew. But we couldn't explain it, and we certainly couldn't scale it.
That conversation became something I couldn't stop thinking about. What if you didn't need 15 years of interviewing experience and some indescribable sixth sense to spot the real candidates? What if you could verify what someone says about themselves against their actual digital footprint — before you ever pick up the phone?
Not "does this resume have the right keywords." But: has this person actually done what they claim? Is their GitHub real? Are their certifications active? Do their employers exist? Is the story they're telling on paper backed up by independently verifiable evidence — or did they write this resume specifically to get past your filters?
That's where Alloy was born. 100+ deterministic checks across public registries, professional platforms, and government databases. No AI opinions. No keyword matching. Every point in the score traces to a verifiable fact. The incentive is to be transparent, not to perform.
We didn't set out to replace recruiters. We set out to give every recruiter — regardless of experience — the same instinct that takes years to develop. Except this version is evidence-based, and it works on the first day.
