About the role

Key responsibilities & impact

Receive a GTM hypothesis and translate it into a precise list of target companies and contacts
Use Clay, Apollo, or similar tools to source, filter, and enrich leads
QA your own output: validate contact accuracy, remove bad fits, flag ambiguous cases with reasoning
Refine lists based on feedback from the sales team after each experiment run
Document your methodology per hypothesis so lists are reproducible without starting from scratch each time
Suggest improvements to hypothesis definitions when you notice patterns in the data

Requirements

What you’ll need

Deep, hands-on experience with Clay, Apollo or similar tools — not just awareness of it
Comfortable pulling and combining data from multiple sources: Apollo, LinkedIn Sales Nav, Clearbit, Crunchbase, funding databases, intent data providers
Strong judgment about what makes a good fit — volume is not the goal, quality is
Solid understanding of the VC-backed startup ecosystem (funding stages, hiring signals, growth indicators) and mid-market enterprise buying dynamics
Able to work from a loosely defined hypothesis and ask the right clarifying questions to tighten it
Background in sales research, SDR, or data enrichment at a B2B SaaS company is ideal — doesn't need to be a full engineer
