What are we building? An AI Executive Assistant

An AI Email & Meeting Assistant that eliminates the admin burden for professionals in client-facing roles. Think sales, consultants, recruiters, people spend hours on emails, scheduling, and follow-ups. Fyxer Al streamlines and automates these tasks by understanding your inbox, drafting replies in your own voice, and taking crisp meeting notes.

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 $18 million in revenue, serving tens of thousands of paying users. In February 2025, we raised a $10 million Series A to accelerate our path to $50 million in revenue and less than six months later, we raised our $30m Series B. Only the top 1% of companies have ever gone from A to B this quickly.

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 see it as farm to table - you nurture the crops, assemble the plates, we just loan you the land.

How will I feed into the Fyxer Growth engine?

We've scaled a pretty hefty "big-block" paid engine - rapid scaling on Meta, Google and alongside optimisation of onboarding sequences and lifecycle email took us from $1m to $18m ARR in 9 months. But we're not 100% sure if all that horsepower is translating to us moving as fast as we could be. We're absolutely not driving blind - but we'd appreciate the help in getting better visibility.



That's where hopefully you come in. Your mission would be to help us refine our analytics around our self-serve acquisition 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 you'd be trying to solve for this side of January:

Refining our fuel mix. Make sure attribution, incrementality testing and geo/MMM views are as good as possible so we never over-fuel or under-boost a channel.

Defining our acquisition LTV. We'd love it if you'd been at the coalface of this before. We have so much rich data which we could use to ensure our CAC:LTV is as defensible as possible, but also act as a goldmine for acquisition and retention optimisation.

Checking our signals. With $Xm going into paid media channels every month, the data we feed our advertising platforms is critical to solid returns; think Conversions API, automated audience parsing from Customer.io.

Getting under the hood. You'd be the go to person for acquisition and retention performance within our Growth Marketing stack. Owning weekly reporting and being the mouthpiece for week to week flags need to be your bread and butter
What does our ideal hire look like?

Must have:

4+ years owning acquisition or activation KPIs as an analyst, preferably in B2B SaaS
Fluent in experiment design, CAC/LTV maths and business storytelling
SQL is non-negotiable. Further languages (R, Python) feel very advantageous
Experience working with or building LTV models from scratch
Experience building multi-cell geo experiments or Media Mix Modelling projects
A sense of urgency and intensity in your work
Ideal:

Worked at an early-stage tech company (
