Founding Customer Success Manager (MarTech) in London

Fluent is a reporting platform built to truly fix reporting for agencies, going beyond pulling and displaying data to produce consistent, narrative-driven client reports, so account managers can spend their time adding value to accounts, not just reporting on them. Fluent was recently acquired by Opteo, and we're now rebuilding the team, bringing existing customers across thoughtfully, and turning our focus to growing adoption with both today's agencies and tomorrow's.

Alongside the Fluent and Opteo product suite, we also run the Agency Growth Programme, which supports agencies as they bring clients onto nascent channels. Supplying the tech to make getting started easier, with one-click account creation and optimisation across all their channels in one platform, while connecting them with opportunities like ad spend vouchers for their clients through Opteo's relationships with TikTok and Microsoft Advertising.

The Team

Across the organisation, we are a small team, around 16 of us in total, most based in London with a few working remotely from abroad. We work in offices within the Fora network, with our main office in Shoreditch and some of the team focusing their time at the Hammersmith location. You'd typically work in person 3 days a week across the two, likely spending most of your time in Hammersmith, so living within easy reach of West London is a real plus. We're the kind of team that genuinely enjoys spending time together. Small enough that you'll know everyone properly, work directly with the founders, and have real influence on what gets built. You'd sit on the Fluent and AGP side of the business, working very closely with Ben, with plenty of opportunity to work alongside the wider team across projects as and when they come up.

The Role

This is a relationship-first, product-close role sitting across both Fluent and the AGP. You'll be the dedicated point of contact for our agency partners, someone they can trust, who gets how they work, speaks their language, and helps them get real value from what we are building.

Fluent: Agency Support and Onboarding

You'll be the agency teams' first point of contact as they take Fluent on. Running onboarding calls, getting teams set up across their client accounts, finding the friction, and bringing real insight back to how we build the product. The work here isn't following a finished playbook, it's helping write one. Your input genuinely shapes where Fluent goes from here. What good looks like is an agency that's fully up and running on Fluent quickly, with the majority of their client accounts connected, and the team genuinely getting value from it from day one. The goal is to make onboarding feel effortless and systematic, so agencies reach that point fast and with no unnecessary friction along the way.

Day-to-day this looks like:

• Running onboarding walkthroughs with agency teams, clear, unhurried and genuinely useful
• Helping agencies connect all their client accounts and get comfortable with the platform
• Being on hand for questions, issues and the inevitable quirks of real-world reporting setups
• Building close enough relationships that agencies tell you what's actually working and what's not
• Meeting agency partners in person where it makes sense, especially London-based
• Gathering case study material, real quotes, real results, real workflows, to inform how we talk about Fluent going forward

You'll act as a knowledgeable, approachable extension of the agency team, the person who reduces the friction around channel adoption, supports partners through account setup and eligibility, and gets called when they need guidance or hit a snag. The brief is simple: feel like part of their team, not someone chasing activity from the outside. What good looks like is an agency that confidently brings clients onto TikTok and Microsoft, knows when those channels make sense, and treats you as their first call when something needs sorting. The goal is for partners to feel materially more capable on these channels because of the support they get, not just enabled, but better at the work.

Day-to-day this looks like:

• Helping agency partners navigate TikTok and Microsoft account creation through the Opteo platform
• Advising on channel strategy, when TikTok makes sense for a client, how to think about starting spend, what to expect
• Sharing channel insight from inside the platforms, what's working, what's changing, what to watch
• Building the kind of relationship where agencies come to you proactively, not just when something goes wrong

What We Are Looking For

Who you are

You've probably spent a few years at a solid independent agency, building real expertise in what you do, and found yourself wondering whether there's a way to keep what you love about the work while doing it differently. You still love the craft, the channels, the people you work with. You're just curious what it would be like to work in tech instead of in an agency. Helping the teams who used to be your peers with tools that make their lives easier, staying close to marketing without being inside an agency yourself.

We're looking for someone who wants to own their role and grow within it. Someone who finds satisfaction in helping agencies get the most out of what we're building. An onboarding that lands well, a partner who feels looked after, a problem that gets sorted. Dependable, proud of the work, and more interested in mastering the role than racing past it. If you want to do great work, be the person agencies actually want to call, and build something you're glad to put your name to, we'd love to work with you.

A Note on Team Culture

We do not have a big team, a structured onboarding programme, or a career ladder mapped out to Director. What we do have is real work that matters, direct access to the people making decisions, and the kind of environment where the right person can genuinely make their mark. You’ll work alongside the founders, get unfiltered exposure to how a product company actually operates, and build direct relationships with the channel teams at TikTok and Microsoft. More than anything, you’ll be in early on something with serious potential. Working hand in hand with the people building it, with the chance to shape how a tech business defines its relationship with its customers from the ground up. If you are energised by that, and not put off by it, we would love to hear from you.
