Fellowship Program

The Thirdpath Fellowship is a highly selective program for exceptional engineers, investors, and builders who want to work at the intersection of technology, data, AI, and private markets.

Fellows don’t observe from the sidelines. They embed directly inside Thirdpath teams, working on real problems that shape how modern private market portfolios are built, analyzed, and managed. This is not a traditional internship. It’s a launchpad.

Public markets are enormous, more than $100 trillion in value, but they increasingly reflect the past, not the future. Public markets tell us how the world is doing. Private markets determine what the world becomes.

Over the last decade, private markets have grown far faster than public ones, compounding at nearly 20% annually and on track to exceed $30 trillion by 2030. What used to be a corner of finance is now the engine of innovation, infrastructure, and economic growth.

Companies stay private longer. More value is created before an IPO. Entire industries: AI, biotech, energy transition, transportation, digital infrastructure are being funded not by governments, not by banks, but by private capital. There are 25 times more private companies backed by institutional capital than public ones. This is where the real work is happening.

This shift is accelerating.

Private markets are enormous, and increasingly complex, but the tools, systems, and workflows supporting them are decades behind.

Thirdpath was founded to change that.

We believe the next generation of investment firms will be engineered, not just managed. The Fellowship exists to bring together people who want to build that future. Side by side with practitioners doing the work every day.

Fellows are embedded in real teams and real workflows. Depending on your background and interests, you will:

• Work side by side with investment professionals and engineers
• Build internal tools across data, AI-assisted diligence, portfolio analytics, and reporting
• Contribute to live investment processes including manager diligence and co-investments
• Help design systems that make private markets more transparent and scalable

• Small, highly selective cohorts
• Paired with senior investment and technical leaders
• Project-based, outcome-oriented work
• Flexible duration with potential for extended engagement

• Direct mentorship from Thirdpath partners and builders
• Access to founders, CEOs, and senior leaders across investing and AI
• Exposure to real decision-making and strategy

As a Fellow, you join a lifelong network of trusted investors, engineers, founders, and operators across finance and technology.

• Engineers interested in private markets and AI
• Investors who want to deeply understand technology, primary fund investments, co investments, and secondaries
• Builders who want ownership, not hypotheticals
• First-principles thinkers who like hard problems

Thirdpath is employee-owned, collaborative, and built for long-term impact. Fellows don’t just see the future being built, they help build it.
