What they build

The product, in plain terms

Quantum Leap builds observability priced for teams that log everything. The company started in Seattle in 2019. We backed it at pre-seed and have worked with the team through Series B.

  1. 01

    A product engineers adopt on their own before anyone signs a contract.

  2. 02

    Performance treated as a feature, with benchmarks published rather than claimed.

  3. 03

    A commercial layer that begins where a team stops being one person and becomes an organisation.

Why we invested

The note from the first meeting

We met Quantum Leap in 2019, back when developers loved things they would not pay for, and that gap was where most of these companies stalled. Two other firms passed in the same month. We thought they were solving for the wrong risk, and we were happy to be alone on the cap table for a while.

  • Signed its first design partner before the program ended.
  • Shipped the enterprise tier without hiring a single sales engineer.
  • Turned down an acquisition offer in year two and was right to.

Founders

Who is building it

Both founders were in the room the day we wrote the check, and both still run the company.

  • Ama Adeyemi

    Co-founder and CEO

    Ran the team that owned this problem inside a company large enough to feel it properly.

  • Viktor Sokolov

    Co-founder and CTO

    Published the research the first version of the product was built on.

Timeline

How it has gone

The version we would give another investor, including the years where nothing looked like progress.

  1. 2019

    Founded

    Ama Adeyemi and Viktor Sokolov start Quantum Leap in Seattle around a single wedge: observability priced for teams that log everything.

  2. 2019

    We invested

    We wrote the pre-seed check. David Chen has worked with the team ever since.

  3. 2020

    Paid customers

    Contracts replaced pilots, and the company stopped selling a roadmap and started selling a product.

  4. 2021

    Series B round

    Raised at $480M, led by an investor we introduced during diligence. We took our full pro rata.

  5. 2026

    Where it stands

    146 people, selling in more markets than it started in, still run by the two people who wrote the first version.
