Careers at Catapult

Catapult is the agent built to handle your most ambitious knowledge work.

By the time you give it your first task, Catapult has already spent hours building an understanding of you and everything you've worked on, across your emails, messages, meetings, documents, and tools.

So it knows how you write. How you decide. What you're building and why. Every project's backstory and what needs to happen next. All as if it had been with you from day one.

That understanding deepens as you work, compounding from one task to the next. No explaining yourself. No markdown files to maintain. No skills to write.

In our internal tests, Catapult outperforms the highest-tier models in Claude Cowork and ChatGPT Work on most knowledge work tasks (See examples).

We’re a deliberately small, obsessed team of repeat founders, researchers and engineers from Meta, Amazon Research, G-Research, Oxford, Cambridge and Imperial.

We will transform how the world works. If that excites you, join us.

What you'll work on with us

Every day, we're solving problems at the frontier of AI. Here are just three of many we're working on:

How do we build a complete understanding of an entire person and company?

We don't use MCPs to pull in user information at inference time. We continually ingest data, allowing us to pre-process it and build a far richer representation than any alternative. As we do, we build memory systems, learn abstract patterns, and construct high-level theories of the user and their data. And that's just the beginning. No one goes deeper than we do, and it shows.

How do we leverage our understanding to take action in the real world?

Building agents that can act in the real world requires understanding a user’s world. That world is particular and complex. It spans sophisticated sources such as databases, spreadsheets, CRMs and many others that cannot simply be “pulled into context.” This requires building an abstract understanding and creating agents that can use it to intelligently—and safely—write and execute programs that read from those sources and take action. How do we build that bespoke understanding? And how do we use it to create the smartest coding agents? Anthropic and others have been struggling with this for good reason.

How do we manage context over long horizons?

This famous open problem, with billions invested in solving it, comes down to building highly effective compaction systems. These systems mimic human memory, predicting what can be forgotten during a conversation and what will matter later. It's an enormously complex process in humans and remains unsolved across AI. Our end-to-end approach, particularly our context engine, opens up unique and promising ways to tackle it.

If you want to work on these problems with us, we want to hear from you.

Why you should not join Catapult

We care deeply about the culture we're building. A culture where exceptional people can do the best work of their lives, have fun doing it, and solve problems that genuinely matter. That requires making deliberate choices about how we work. And it means Catapult won't be for everyone.

If you're more excited after reading the above, we want to hear from you.

FAQs

How will you beat Anthropic and OpenAI?

Claude and OpenAI are building increasingly intelligent general models. We are solving a different problem: giving AI a deep, persistent understanding of your work.

Their connectors and MCPs retrieve a few emails, messages or documents after you ask a question. Catapult already understands how those conversations, people, projects and decisions connect, and keeps that understanding current as your work changes.

Models will keep improving and we can use whichever one is best. Our advantage compounds separately: a living model of you, your company and how work actually gets done. Better intelligence helps everyone. Better context makes Catapult better for our users.

In our internal tests, Catapult outperforms the highest-tier models in Claude Cowork and ChatGPT Work on most knowledge work tasks. Examples include:

  • Answering complex questions across your work by tracking down the data, decisions and history scattered across meetings, messages, documents and tools.
  • Drafting emails in your voice after reading the whole thread, understanding the relationship and checking every promise still outstanding.
  • Creating social posts from work you had forgotten about, finding the strongest product progress, customer proof, conversations and lessons before writing them in your voice.
  • Turning meetings into next steps by working through what was decided, updating the plans and drafting every follow-up people promised.
  • Building board packs and investor updates by pulling together the latest financials, company metrics, progress, risks and commitments from previous meetings.
  • Spotting which leads to contact after every release, matching what shipped to what each person previously asked for and drafting the messages.
  • Drafting PRDs after reading the codebase, listening to user calls and tracing the decisions that shaped the product.
  • Preparing you for customer meetings by remembering the full relationship, what each person cares about, what you promised and what remains unresolved.
  • Drafting proposals and statements of work by turning customer conversations, pricing, product capabilities and implementation requirements into a finished document.
  • Completing RFPs, RFIs and due diligence by finding the latest answers from across the company and filling in every spreadsheet and document.
  • Answering questions about company performance by finding the right numbers, checking where they came from and explaining what changed.
  • Creating tickets for recurring problems by pulling together the user reports, internal conversations and evidence engineers need to ship the fix.
  • Updating the sales pipeline from what actually happened across meetings, emails, proposals, product usage and promised next steps.
  • Turning recurring customer feedback into product priorities by finding the patterns across calls, support threads, usage data and internal conversations.
  • Finding commitments that are about to be dropped, working out who is waiting on what and drafting the messages needed to close each loop.
  • Planning renewals and expansions by bringing together product usage, customer requests, support history and recently shipped features.
  • Working out why a project is late by retracing the original plan, changed requirements, dependencies, blockers and decisions behind it.
  • Bringing new joiners up to speed on the product, its history, why decisions were made, who owns what and how work actually gets done.
  • Writing stand-ups, performance reviews and progress updates from the work people actually did, including contributions nobody remembered to record.
  • Completing security questionnaires by finding current answers across your architecture, policies, controls, vendor records and previous responses.
  • Evaluating candidates by reading the job spec, CV, application, interview history and how you assessed similar candidates.
  • Updating financial models with actuals and new assumptions, preserving the formulas and showing you exactly what changed.
  • And many more.
What makes Catapult technically difficult?

Real work is messy. A single decision might begin in a meeting, continue in Slack, appear in an email and eventually change a document or customer plan.

Catapult must understand those connections across millions of pieces of information, keep that understanding current, respect permissions and reliably select the right context for each task. We are also solving evaluation, safety, document understanding and agent execution across wildly different customer environments.

What is your interview process?

Our typical process is:

  1. A founder interview focused on your background, ambition and how you think.
  2. A follow-up conversation about problem-solving and judgment.
  3. A deeper session where you present something you know exceptionally well and work through a real Catapult problem on a whiteboard.
  4. A paid work trial in our office.
  5. References & offer extended.

We do not rely on generic coding tests. We care more about how you reason, communicate and work on a difficult problem with the team.

Do you sponsor visas?

Yes. We sponsor visas for exceptional people and already have the infrastructure to do it.

We care about finding the best person, not where they were born or which passport they hold. If there is a strong mutual fit, we will work with you on the appropriate UK visa route and cover the company side of the process.

What compensation and benefits do you offer?

We offer competitive salaries and meaningful stock options because we want everyone at Catapult to share in the upside they help create.

Our UK benefits include:

  • Bupa private healthcare
  • A wellbeing allowance
  • A tax-efficient pension scheme
  • 34 days of paid holiday, including public holidays
  • A workplace nursery benefit
  • All the equipment you need to do your best work
What should I expect in my first few months?

You'll contribute from day one and take ownership of meaningful problems within your first month, turning them into something users rely on. Expect direct support, fast feedback and broad responsibility, not layers of management or a narrow box.
