Mercor Head of Product on Revenue Concentration from Frontier Labs

Osvald Nitski is the Head of Product at Mercor, the AI-training and expert-data marketplace powering frontier-model development. Mercor last raised a $350 million Series C at a $10 billion valuation, and is reportedly in discussions for a new round at a $20 billion valuation. Mercor crossed $2BN in ARR in June; doubling from $1 billion in only four months. ----------------------------------------------- Timestamps: 00:00 Intro 01:12 Does Open-Source Cannibalize Mercor's Core Business? 02:29 Why 90% of Enterprise Workflows Can't Be Done With Open Models 07:47 Do We Have an Enterprise AI ROI Problem? 09:05 Balancing Token Spend vs Performance 10:07 Salesforce Spends $300M on Anthropic 12:13 AI Makes the PM Role Harder, Not Easier 14:55 The Biggest Product Mistake 22:42 Why RL Environments Are the Fastest-Growing Data Type Right Now 28:28 How Mercor's Product Teams Are Structured 33:54 The Three Secrets to Scaling Supply on the Marketplace 38:04 Mercor Has High Revenue Concentration 43:47 Why Data Projects for Enterprises Are So Operationally Intense 51:02 Why Cybersecurity Data Will Never Hit the 90% Sufficiency Ceiling 52:15 Hiring in SF: Brutal Talent War & What Mercor Looks For 54:15 Quick-Fire Round ---------------------------------------------------------------------------------------------- Subscribe on Spotify: https://open.spotify.com/show/3j2KMcZTtgTNBKwtZBMHvl?si=85bc9196860e4466 Subscribe on Apple Podcasts: https://podcasts.apple.com/us/podcast/the-twenty-minute-vc-20vc-venture-capital-startup/id958230465 Follow Harry Stebbings on X: https://twitter.com/HarryStebbings Follow Osvald Nitski on X: https://twitter.com/OsvaldNitski Follow 20VC on Instagram: https://www.instagram.com/20vchq Follow 20VC on TikTok: https://www.tiktok.com/@20vc_tok Visit our Website: https://www.20vc.com Subscribe to our Newsletter: https://www.thetwentyminutevc.com/contact ----------------------------------------------- #20vc #harrystebbings #founder #entrepreneur #mercor #ai

WHAT IT’S REALLY ABOUT

Mercor CPO on data moat, enterprise ROI, and revenue concentration

  1. Open-source model gains raise the baseline but don’t eliminate demand for frontier data, because customers still pay for datasets that close specific capability gaps at the edge of performance.
  2. The popular claim that “90% of enterprise workflows are solved” misses latent demand—especially long-horizon agent workflows—and overuses a binary sufficiency framing where many tasks have uncapped, continuous improvement value.
  3. Mercor argues there isn’t an enterprise AI ROI crisis yet; most companies are still experimenting while token prices and model capabilities shift, but spend discipline is emerging and must be tied to outcomes.
  4. AI increases product-management difficulty by accelerating engineering output while making focus, simplification, and experiment quality the true bottlenecks—driving a higher PM-to-engineer ratio over time.
  5. Mercor’s high revenue concentration in frontier labs is addressed by moving downmarket via self-serve tooling and “AI project managers” that make operationally intense human-data projects easier for enterprises.

IDEAS WORTH REMEMBERING

5 ideas

Open source raises the floor, but frontier customers still buy the edge.

Mercor sees open models as eliminating demand only for capabilities that are already commoditized; the most valuable datasets remain those that push specific frontier gaps for labs with unique objectives.

The “90% of workflows” narrative undercounts what enterprises will attempt next.

Osvald argues many calculations ignore latent demand—especially long-horizon agentic automation (e.g., procurement agents running for weeks)—which expands the addressable market for eval and training data.

Binary ‘can it do it’ thinking breaks down in uncapped-reward work.

For tasks like legal reasoning, medical advice, and cybersecurity, performance can always improve and incentives remain strong, so adoption and spend should be modeled as continuous optimization rather than a completion percentage.

Enterprise AI ROI is not ‘broken’—it’s still in a volatile exploration phase.

Because performance and token costs are changing quickly, companies tolerate ambiguity while testing; Mercor expects more rigorous outcome-linked accounting and differentiated spend profiles by team function over time.

Token spend strategy should match whether usage drives growth or unit economics.

High spend can be rational for compounding productivity (e.g., coding agents) even if it’s not classic COGS, but customer-support agents with token costs exceeding served revenue signal a broken model.

WORDS WORTH SAVING

5 quotes

I wouldn't say that open source model improvements cannibalize our core business because data is most valuable on the frontier of model performance.

Osvald Nitski

I don't think there's an ROI problem right now. I think we're in a period of exploration and experimentation where there's more, uh, tolerance, more patience to get that ROI calculation right now.

Osvald Nitski

I think this paradigm makes the job of product management a lot harder because we're trying not to build 10X more product surface area. It makes things incredibly chaotic.

Osvald Nitski

Don't delegate your decision-making, like, your actual job to a model, because you're gonna, you're gonna lose that ability, and then you're gonna get psychosis.

Osvald Nitski

We end every week with so much more money in the bank. Like, the business is, is very healthy, and we can't, we can't spend money fast enough. So what people, you know, wanna, uh, call it is, you know, up to them, but, like, the, the cash flow is insane.
