Growth Manager

This role pays £65k-£90k/year DOE & equity & other benefits. We work from our office in Chancery Lane, London, Monday to Thursday. Fridays are optional work-from-home days.

What are we building? An AI Executive Assistant. We’ve built an AI executive assistant that looks at your emails, messages, and meetings, and uses that knowledge to answer your emails, schedule meetings, take next steps from meetings, and organise your inbox. Unlike other startups, we’re a pure-play applied AI company and not a SaaS company with AI features hastily bolted on. We use 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? Since our launch in March 2024, we’ve grown from $0 to $8 million in revenue, serving thousands of paying users. In February 2025, we raised a $10 million Series A to accelerate our path to $50 million in revenue and are backed by top-tier investors including Marc Benioff (CEO of Salesforce) and 20VC.

What do we value? We’re very intentional about adding new people. We believe a small team of exceptional people working hard at a problem they care about will always outperform a larger, more unfocused team. That means you’ll need to bring an intensity to this role that might not be expected at other companies but it also means you’ll be fast-tracked into roles with greater responsibilities far earlier. We also believe in hiring people who want ownership and autonomy in their work and giving it to them. We hire T-shaped individuals who can own the entire growth lifecycle, end to end. Instead of just driving down CPA or improving conversion rate, you’ll look at the whole funnel and user experience: shaping the roadmap by thinking from first principles, looking at usage data, and speaking to customers then architecting and implementing your ideas. We look for adaptable people that will be able to turn their hand to the highest impact areas of our growth.

How will I feed into the Fyxer Growth engine? We’ve proved that a "big-block" paid engine works - rapid scaling on Meta, Google and cold email took us to $8 m ARR in 12 months. Now we’re finessing the power-train: a lean, hybrid system where every sensor, turbo spin and KERS element (read: PLG, content and referral loops) compounds growth at just the right fuel burn. Your mission is to refine and help drive that system for our self-serve funnel: get more business users to connect their work inbox, hit the "aha, draft sent" moment, and return daily - without ever talking to sales.

Types of projects we’re trying to solve for this month:

• Dial-in the sensors. Make sure attribution, incrementality testing and geo/MMM views are as good as possible so we never over-fuel or under-boost a channel.
• Refine the fuel mix. Forecasting 13-week channel plans for Meta & Google, explore new channels only when they can realistically reach ≥ 20 % of media mix.
• Spin the turbo. Build out our Lifecycle/CRM capabilities to tighten onboarding and monetisation flows (PostHog events → Customer.io triggers).
• Getting under the hood. Understanding our product growth loops. Long term growth comes from our product, not just marketing.

What does our ideal hire look like?

Must have:

• 4 - 8 yrs owning acquisition or activation KPIs, preferably in B2B SaaS.
• Fluent in experiment design, CAC/LTV maths and storytelling that earns budget.
• Enough SQL (or AI) and analytics knowledge to pull your own numbers (but you won’t live in the code).
• Experience moving beyond paid into lifecycle, referral or product-led loops.
• A sense of urgency and intensity in your work.

Ideal:

• Worked at an early-stage tech company.
