Introducing Kepler

The Problem

High-stakes industries are falling behind on AI adoption. Their workflows can’t afford wrong answers. And AI can’t be trusted to give right ones because of hallucinations. The barrier isn’t that the models aren’t smart enough. It’s that no one can verify what they produce. The fix isn’t a better model, it’s a trust layer: every output traceable, every calculation auditable, every answer reproducible.

What Kepler Is

Kepler is the agent harness - the infrastructure layer that wraps around AI models to make their outputs reliable, traceable, and verifiable. The model is a replaceable component. The harness is the product.

In Kepler's architecture, the LLM orchestrates - it decides what data to gather, what to compute, how to structure the output. But every actual data point, every extracted value, every calculation flows through deterministic code pipelines. The LLM never touches the data itself. Every value carries provenance metadata back to its exact source. Every computation is auditable and reproducible. Verification loops cross-check outputs before users ever see them.

We started in finance because the stakes are highest and the tolerance for error is zero. We’ve built a finance research product that lets analysts supercharge their workflow: pulling comparables, building models and researching filings. No more double-checking every number AI spits out. Every number tracing back to the source, every time.

But the architecture - provenance, deterministic computation, verification - applies anywhere trust in AI output matters: chemicals, legal, healthcare. Models are commoditizing fast. The trust layer is what's missing and the market is massive.

The Team

The founding team spent a combined 40+ years at Palantir building the type of large-scale data infrastructure that Kepler requires. Our founding engineers led Foundry's core systems - Ontology, Fusion, Workshop, FoundryML, created Palantir's first AI platform and scaled data products at Meta to 1B+ users.

We’ve paired this deep technical foundation with a repeat founder profile. Our CEO built and scaled a data company to $15M ARR before successfully selling it. He then became Citadel's first Head of Business Engineering, experiencing first hand the problems we are now solving. We have a team who’ve been on both sides: building systems like this at massive scale and selling it into the buyers who need it most.

We’re backed by investors who built the modern AI and data stacks, plus the builders of iconic commercial businesses. This includes founders of OpenAI, Meta AI Research, MotherDuck, dbt Labs and Square as well as PebbleBed, Company Ventures and Mantis VC firms.

The Role

What You'll Own

You'll own how we get in the room with the investment teams we want to work with: who we meet, where we meet them, and how a first conversation turns into a working relationship. The people we work with are portfolio managers, CIOs, CTOs, and heads of data and AI at hedge funds, private equity firms, and allocators. Most of them don't answer cold email. The conversations that matter start with an introduction, a dinner, or ten minutes at a conference, and they go somewhere when the person across the table feels understood.

A lot of the job is teaching. Most firms are still working out what AI should do inside their walls, and many of their engineers are trying to build it themselves. You'll explain how our system works, why we split the work between code and the model, how it fits the data and tools a firm already has, and what deploying on their data actually involves. You'll often do that for a PM and a CTO in the same meeting, so you'll need to understand the technical side in real depth.

This is a senior individual contributor role with no quota or territory. You'll be the person a PM treats as a peer: someone who has sat in a seat like theirs, talks about their workflow in their language, and leaves a meeting with a sharper read on what they need than they gave. Our CEO stays close to our most important relationships. Your job is to make sure there are more of them, at the firms that matter most to us.

Some of this you'll do alongside other members of the team, but all of it is yours to elevate and make stronger.

In the first few weeks you might:

In the longer term, you'll build how we grow our relationships with investment firms: the events, the partner channels, the advisors, how we run a deal from first meeting to signature, and, when the volume calls for it, the team. You're the first person here whose whole job is the market, so a lot of what the function becomes is going to be your call.

How We Work

We're a close team, working together in an office in New York (with Wagyu, our office dog). We use AI tools heavily: Claude, Cursor, whatever makes us faster. Fluency is assumed. Our engineers work directly with each customer on the customer's own data, and you'll often be in those rooms with them.

The pace is startup-fast but the bar is high. Our buyers have heard every pitch for AI in finance, and they remember the ones that didn't hold up. Our sales cycles are long: a deal often takes months of conversations, a scoping session, a security review, and an evaluation phase, with a PM, a CTO, and often someone above them weighing in before anyone signs. We'd rather have fewer conversations that turn into real work than a calendar full of meetings that go nowhere.

The team has strong backgrounds and low ego. We expect everyone to roll up their sleeves and handle the unglamorous problems: the follow-up note at 11pm after a conference dinner, the 7am breakfast before a client meeting, the meeting list that has to be rebuilt the day before an event. We move as a team, not as a collection of individuals.

Who You Are

You've worked on the buy side, or close enough to it that portfolio managers and CIOs treat you as one of their own. People take your calls because you've been useful to them for years. You'd rather be in the room than behind a screen, and you can tell a meeting that went well from a relationship that's going somewhere. You want to understand how things actually work, and you're happy to spend an afternoon with an engineer to get there. You're drawn to early stage because you want to build those relationships from the start, with a product you can stand behind.

From the craft side:

From the personal side:

Don't check every box? Apply anyway. We prioritize judgment about people, credibility with buyers, technical depth, and drive over a specific résumé shape.
