Rav
Co-founder & CEO
2x startup founder and former EMEA Lead at Meta, where his team helped roll out new products and scale engagement. Previously built the "Netflix for News", where he brokered deals with the world's leading media companies.
We're building agents with a deep understanding of you and the complete context of your work. So, they already know what you're working on, the backstory behind it, and what's next. And as you work, Catapult continually learns, remembers, and improves, taking more and more meaningful work off your plate.
It's still early, but Catapult already outperforms Claude Fable 5 and comparable OpenAI models on most knowledge work tasks when connected to Gmail, Drive, Notion, Granola, and Slack. It does so at a fraction of the cost, and we're just getting started.
We're a deliberately small, obsessed team of repeat founders, researchers, and engineers from Meta, Amazon Research, G-Research, Oxford, Cambridge, and Imperial.
We have many seemingly impossible challenges ahead of us as we transform the way the world works. If that excites you, join us.

Why you should not join Catapult
- This is not a nine-to-five job. We're obsessed with the problem we're solving and determined to build the best product in the world. Nobody tracks your hours, but everyone thinks deeply about the work and takes real ownership of the outcome. If you're not thinking about the problem in the shower, you're not going to make the progress you need to.
- If solving something seemingly impossible scares you rather than excites you, we're the wrong place for you. At Catapult we frequently deal with problems that no one (not Google, Anthropic, OpenAI, or the research community) has a handle on, and tackle them head on with enthusiasm.
- We work together in person from our office in London. We believe difficult, ambiguous problems are solved faster when you can talk directly, use a whiteboard and keep moving. We are flexible for genuine personal needs, but we are not a remote or hybrid company.
- We have no room for ego. We care about finding the right answer, not defending our own ideas or proving who is smartest. We make mistakes, challenge each other directly and change direction quickly when the evidence says we should.
FAQs
What is your interview process?
Our typical process is:
- A founder interview focused on your background, ambition and how you think.
- A follow-up conversation about problem-solving and judgment.
- A deeper session where you present something you know exceptionally well and work through a real Catapult problem on a whiteboard.
- A paid work trial in our office.
- 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.
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, workplace nursery benefit, and all the equipment you need to do your best work. We can also sponsor UK work visas for exceptional candidates.
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.
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 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.
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.
Connectors 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.
