Company Description: Foundy.com — an AI-native M&A advisory platform building a world-first matching engine for business sales.

Job Description: You will architect a novel algorithmic engine to match business sellers with buyers using dual conversational AI agents. As a fractional technical leader, you will audit existing no-code infrastructure, design a scalable scoring system, and draft technical specs for execution. This role combines high-level architecture with long-term strategic engineering management.

Why this role is remarkable:

  • Architect a world-first product applying conversational AI agents to the $50B+ M&A industry, turning relationship-driven brokering into an algorithmic science.
  • High-impact fractional equity stake (1.2%) in a funded startup with a £2M+ pipeline and proven product‐market fit.
  • Flexibility to lead high-level technical strategy and team building without the daily grind of full-time execution, while owning essential industry infrastructure.

What you will do:

  • Conduct a technical audit of current Supabase and Vapi integrations to define a production-ready roadmap and scalable data model.
  • Design the proprietary matchmaking scoring algorithm that weights buyer‐seller signals to deliver surgical targeting and valuation uplifts.
  • Create detailed technical specifications and a hiring scorecard to recruit and manage the mid-level engineering team through to exit.

The ideal candidate:

  • Proven experience building multi-agent conversational AI or voice systems (Vapi, Retell, LangGraph) in production environments.
  • Background designing complex two-sided matching engines or scoring systems for marketplaces, recruiting platforms, or financial services.
  • Senior leadership experience at post‐seed / Series A startups with the ability to translate non-technical founder vision into robust engineering architecture.
