About:

LH2 Data Labs (lh2.ai) licenses proprietary datasets and verified expert networks to frontier AI labs and enterprise buyers. We source rights-cleared data - code, co ops data, multilingual audio, medical - from populations and domains underrepresented in public corpora, and pair it with vetted domain experts.

The role:

HIGH-AGENCY BUILDERS - everything else can be learnt.

We're hiring someone to own the supply side of one of our verticals end-to-end. You take a clear spec of what we need to acquire - coverage, formats, quality bar, rights - and you go build it: find the supply partners, sign them, and manage those relationships to deliver against the spec. Each vertical at LH2 runs like its own small business, with its own supply economics, quality bar, and growth roadmap. The buyer conversations sit with the founders. Your mandate is supply: build the moat and keep it producing. That means originating relationships with companies, archives, publishers, institutions, and individual contributors - then operating a portfolio of those relationships so the data and experts keep flowing at the standard our buyers demand.

Key responsibilities:

- Build the supply network

- Take the acquisition spec for your vertical and turn it into a sourcing plan - who to approach, in what order, and on what terms.

- Originate net-new supply relationships: companies, archives, publishers, institutions, and individual contributors.

- Recruit, credential, and retain domain experts where the vertical calls for an expert bench.

- Negotiate acquisition terms with each partner and close them.

- Run the supply portfolio

- Own a portfolio of supply partners and manage each relationship over its life - onboarding, throughput, renewals, and issue resolution.

- Hold the quality bar: assess incoming data and experts against the spec and reject what doesn't clear it.

- Track coverage against the spec and chase down the gaps.

- Protect margin - keep acquisition economics inside the targets set for the vertical.

- Operate the engine

- Keep projects moving from sourced to shipped, on time and at standard.

- Feed supply reality back to the founders - what's available, at what cost, and where the constraints are.

What we're looking for:

- 2-5 years in operating, sales, partnerships, or program roles - ideally where you've owned a target or a P&L line, not just a project.

- A track record of originating and managing many partner relationships at once, against numbers, without hand-holding.

- Comfortable negotiating non-standard, bespoke terms - not just working a fixed price list.

- Resilient and process-disciplined - you can run the grind of multi-partner management and keep quality high.

- Sharp judgment on quality - you can tell what clears the bar and what doesn't.

- High ownership; comfortable in fast, ambiguous environments.
