People

The people who do the work.

Four partners, a small operating bench, and a single principle: only invest where you can be useful — and only with the kind of founder whose attention runs the way ours does. We are unlikely to grow.

Partners

  • 01

    Daniel Reiss

    Founding Partner

    With a10 since 2021

    Before a10, Daniel was a partner at a generalist seed firm for seven years, where he led the early-stage technical practice. Earlier, he founded an analytics company acquired by an infrastructure firm in 2014 and spent two years inside it.

    He writes the firm's annual letter and reads almost every cold email. He is interested, somewhat narrowly, in compilers, formal methods, and the people who care about them.

    Mira Iskandar

    Partner

    With a10 since 2022

    Mira was a research engineer at a frontier AI lab and, before that, a member of technical staff at a systems-software company. She co-authored two of the most-cited papers on training-time interpretability and started two of her own companies before joining a10.

    She covers the firm's work in applied AI and is the partner most likely to ask, on a first call, what the founder thinks is wrong with their approach. She has a low tolerance for meetings that perform interest rather than hold it.

    Henrik Søderberg

    Partner

    With a10 since 2022

    Henrik spent eight years as a principal engineer at infrastructure companies, including a stretch as the second engineering hire at a content delivery network. He has, by his own count, started a string of failed companies; he considers each of them a useful education.

    He covers the firm's work in systems software and developer tools. He prefers conversations that do not stop until the problem stops moving, and he is responsible, over a partners' lunch in 2023, for the rule that no investment memo may exceed five pages.

    Quinn Adeyemi

    Partner, Operations

    With a10 since 2023

    Quinn built engineering teams at three category-defining companies before joining a10. She is the partner the firm's founders speak to first when they are hiring, restructuring, or trying to recover from a difficult quarter.

    She runs the firm's recruiting practice and reads the code reviews of every portfolio company on a rotation. She holds, like everyone here, a faint suspicion of people who claim to context-switch easily, and keeps the firm's only spreadsheet.

Operating bench

Anonymous, on purpose.

A small group of operators and researchers we keep on retainer for the firm's portfolio. They are not advertised because their employers would prefer it that way. All six are, by self-description, the kind of person who has never quite stopped working on the same problem. Our founders know who they are.

  • An applied cryptographer

    Security & infra

  • A formerly-public CTO

    Hiring & technical leadership

  • A research mathematician

    Frontier AI & evaluation

  • A clinical neuroscientist

    Bio & applied research

  • A staff compiler engineer

    Languages & runtimes

  • A regulatory counsel

    Health, finance, defense
