What Calyptus does
Calyptus is a London-headquartered, bootstrapped AI talent platform founded in 2022 by Dan Jones (CEO, ex-deeptech VC) and Callum Crombie (CCO, HRtech background). The company connects employers with pre-interviewed, video-screened candidates across sales, marketing, and technology roles, with particular focus on hiring professionals who are demonstrably fluent in AI and automation tools. Its customer base of 150+ employers spans high-growth AI, tech, and Web3 companies including Aragon, Avara/Aave, IBM, Optimism, Unravel, and Goodtime.
The platform's core technology layers AI candidate sourcing (scanning public profiles from LinkedIn and GitHub) with a structured screening pipeline. Inbound candidates interact with Alex, an AI interviewer that conducts 10–20 minute video conversations and produces five-dimension scored profiles (communication, AI fluency, skills, cultural fit, experience). Outbound candidates are vetted by human recruiters using the same scoring framework. AI output is reviewed monthly by Warden AI for bias and alignment with NYC Local Law 144, California employment AI rules, and the EU AI Act. The platform integrates Day 1 with Greenhouse, Lever, Workable, Ashby, Slack, and email; video infrastructure is provided by HeyMilo (SOC 2, GDPR), technical assessments by Coderbyte, and global payroll/compliance for 140 countries by Deel.com.
Calyptus operates on a primarily transaction-based revenue model: 18% of first-year base salary for the first hire, 20% for subsequent hires, with a 100-day replacement guarantee and a 12-week sliding refund if a placement leaves early. Secondary streams include a margin on hourly contract work and a per-qualified-lead subscription billed quarterly or annually. Go-to-market is direct sales with co-founder-led demo calls and a content engine (Coffee with Calyptus podcast, blog, referral program), targeting mid-market and enterprise employers globally with a deliberately lean team of roughly 15–20 employees.
