What are we building? An AI Executive Assistant
In 1930, the economist John Maynard Keynes predicted that we’d only be working 15 hours a week by 2030. Despite automation in agriculture and industry, that hasn’t happened.
Why? The service sector. Walk around the average office and you’ll see people’s days taken up by emails, Slack and meetings instead of real work.
People in client facing roles - think sales, professional services firms, recruiters - feel this pain most acutely. Instead of advising and connecting with clients, they spend hours doing admin. Following up. Scheduling meetings, then taking notes on them. Answering questions they’ve been asked a thousand times. Sorting through the mess that is their inbox.
We’ve built an AI executive assistant that looks at all your emails, messages and meetings, and uses that knowledge to answer your email, schedule meetings, take next steps from meetings and organise your inbox. We turn every employee into a top performer, effortlessly.
Unlike other startups, we’re a pure-play applied AI company, not a SaaS company with AI features hastily bolted on! We make use of the best techniques (fine tuned open source models, tool use, and retrieval augmented generation) and as a result, users send 53% of the email drafts we generate.
How has it been going?
We launched our product in March 2024. Since then we’ve gone from $0 to $4.5m in revenue, across thousands of paid users. We’ve done this with a team of just 4, without using any paid marketing until the start of November 2024.
What do we value?
We’re very intentional about adding new people. We think a small team of exceptional people working hard at a problem they care about will always beat a larger, more unfocused team. That does mean you’ll need to bring an intensity to this role that might not be asked at other companies. But it also means you will be fast tracked into more senior roles and responsibilities far earlier. We predict we’ll reach $20m in revenue by the end of 2025 - there will be plenty of opportunities for you!
We also believe in hiring people who want ownership and autonomy in their work, and giving it to them. We only hire product engineers. What that means is instead of just being given tickets to implement, you’ll be owning a whole product: shaping the roadmap by thinking from first principles, looking at usage data and speaking to customers, then architecting and implementing your ideas.
What does our ideal hire look like?
We are looking for a Cybersecurity Engineer with at least 2 years of hands-on experience to support our cybersecurity initiatives and help safeguard our digital assets. You will work closely with senior engineers to detect, prevent, and respond to threats while also contributing to the development and enforcement of security best practices. This is a great opportunity for someone who has moved beyond entry-level tasks and is ready to take on more responsibility.
- 2+ years of professional experience in cybersecurity, IT security, or a related technical
- role.
- Familiarity with cybersecurity frameworks and standards (e.g., NIST, CIS Controls, ISO
- 27001).
- Working knowledge of networking, operating systems (Windows/IOS), and security
- protocols.
- Experience with one or more security tools (e.g., Splunk, Nessus, CrowdStrike, Palo Alto,
- Wireshark).
- Basic understanding of cloud security concepts (AWS, Azure, or GCP is a plus).
- Ability to analyse logs, spot anomalies, and investigate potential threats.
- Strong troubleshooting and documentation skills.
- Security certifications such as Security+, CEH, or CySA+ are preferred but not required.
- Exposure to scripting (Python, PowerShell, Bash) for automation tasks.
- Experience participating in tabletop exercises or incident simulations.
- Awareness of emerging cybersecurity threats and attack techniques.
A bit more about what you will be doing:
