The Opportunity

In the past few years, 20+ new state and federal leave laws have emerged in the US. By 2030, US employers are expected to spend over $40B annually on employee leave protection. While this is a win for employees, it creates massive complexity for employers and insurance carriers.

Today’s leave administration processes are fragmented, slow, and painful. We are building the next-generation Data infrastructure for HR and Insurance to:

  • Orchestrate data between HR and insurance systems
  • Simplify the leave of absence experience for employees
  • Reduce the operational burden for employers, carriers, and TPAs

We are backed by Diagram and are working alongside insurance carriers as co-design partners to launch our MVP. We are now looking for an exceptional technology leader to join as CTO & Co-Founder. This is a unique chance to co-found a company with major early traction and the support of one of the world’s most successful venture studios.

Note: This is not an employment opportunity at Diagram, but a co-founding role within a new company launched through the Diagram venture studio.

What You’ll Do

As CTO & Co-Founder, you will own technology and engineering from day one. Expect to:

  • Lead as a co-founder — share full accountability with the founding team for growth, scale, and long-term success.
  • Build the team — recruit top technical talent and create a strong, high-performance engineering culture.
  • Code and ship — roll up your sleeves, architect, and write code in the early stages.
  • Move fast — thrive in ambiguity, embrace speed, and focus on outcomes over process.
  • Drive AI-native thinking — embed intelligent automation into every layer of the product.

Who You Are

You’re a builder and entrepreneur with the grit to thrive in an early-stage startup.

  • Proven builder — you’ve taken a company, product, or major business unit from 0→10 with full technical ownership.
  • Integration expert — strong background in connector/integration products, ideally with leading SaaS/cloud players (e.g., MuleSoft, Boomi, Informatica, Zapier, Fivetran, Finch, Merge, etc.).
  • Hands-on technologist — you are excited to code, prototype, and push products forward directly.
  • Fast mover — comfortable with limited process, high ambiguity, and rapid iteration.
  • Talent magnet — experience hiring, developing, and leading world-class technical teams.

What’s In It For You

Joining us as CTO & Co-Founder is a rare chance to step into a high-upside venture without the “starting from scratch in a basement” hassle.

  • High equity compensation — meaningful ownership in the company.
  • Leadership from day one — co-found alongside other high-caliber founders with a validated roadmap.
  • De-risked startup ride — traction already in place:
    • Pipeline of partners, investors and clients
    • Product roadmap validated through extensive research during Diagram incubation
    • Other strong co-founders already on board
  • Unfair advantage — leverage Diagram’s deep insurance network and relationships with carriers.
  • Proven venture studio model — Diagram has one of the best track records in the industry: out of 25+ ventures launched thus far, 80% make it at least to Series A, with several exits including 1 IPO in less than 10 years.
