Customer Lifecycle Manager in London

Junior is building the voice, research and context management layer for the private M&A industry. Investment and advisory firms run on conversations, and the richest context for any deal decision sits inside them. We started with compliant voice transcription and insight generation, and we are extending into the adjacent CDD workflows: surveys, voice agents, slides, and report drafting. Within 18 months, a consultant will press a button on Junior and get a 70% first-draft commercial diligence report in hours. Work that took six people a month will take two people two weeks.

We are profitable and bootstrapped, around 40 people in London, New York and Sydney. Revenue has grown 20x in the last 24 months and we exited April at $21m run-rate. We work with every major consulting firm except McKinsey and Bain, and half the top 30 PE funds by AUM. NPS is over 80. Our go-to-market is deliberate: we sell through advisors, not around them. The incumbents have the brand, the relationships, and the institutional knowledge to win the AI transition, and Junior is the platform that gets them there.

The Role

We have users, customers, and prospects engaging with Junior in different ways every day. Right now, most of that experience is manual, inconsistent, or not happening at all. Activation emails are ad hoc. In-product nudges and clear training programmes aren’t built out. Reactivation is something we talk about, not something we run. We have features in the product that paying users are not using because we have not told them clearly that they exist.

This role owns the system that fixes that. You'll be Junior's first dedicated Lifecycle hire, designing and building the automation engine that engages the right user, at the right moment, with the right message, without us doing it by hand. You will not be running broadcast campaigns to broad lists. You will be building targeted, behaviour-triggered programs for a small, high-value B2B audience where every account matters and one well-timed message can move a deal.

You'll report to our CS Lead and work closely with Product, Marketing, and Data. You're a founding hire for this function. If it goes well, you build a team around you.

What you'll own

• The full lifecycle automation engine. Activation, adoption, expansion, reactivation. Built from zero. Utilise our tools (Customer.io, Attio, Segment etc.) - we can train you here too.
• In-product and email messaging. Triggered by behaviour, usage, and key events. Not a newsletter. A built system across the full customer journey pre-product, onboarding and in full user flow.
• Targeted campaigns to the right segments. Working with the Founding Marketer and leadership to put thought leadership and product content in front of the users who need it, not everyone on the list.
• Adoption of features that already exist. Pick an underused feature each month, design the play, ship it, measure the lift. This is a CEO priority and you’ll be working very closely with our Founding Marketer and Product here.
• A scalable, automated support and training experience. A knowledge base, guided flows, and automated responses that let users move forward without a manual touch. Work with product and CS to identify recurring friction.
• Lifecycle tracking and visibility. Define how we track user behaviour across the lifecycle. Build the view of how users move between stages or drop off. Work with Data and RevOps to make tracking accurate and usable.
• Reactivation and dormant account engagement. Identify inactive users and under-engaged accounts. Test approaches, scale what works.
• Performance and reporting. Engagement and downstream impact, not sends and opens. You are measured on activation rate, feature adoption, reactivation, and revenue influenced.

About You

You think in systems, not one-off campaigns. You are equally comfortable mapping a flow in Figma and writing the email copy that runs through it. You measure what you ship and you iterate. You care about outcomes, not vanity metrics.

Must-haves

• 4 to 7 years of relevant industry experience. Owned lifecycle, growth, or CRM marketing at a high-growth B2B SaaS. Bonus if you joined sub-100 and saw it scale. Bonus again if you have worked on a low-volume, high-value B2B audience (PE, consulting, financial services, enterprise SaaS) rather than D2C or PLG mass market.
• Built a lifecycle engine from zero. You can walk us through the journeys you designed, the triggers you set, the tools you picked, and the numbers that moved as a result.
• Strong segmentation and behavioural targeting. You do not blast lists. You can explain how you decide who gets what message and when.
• You write well and can produce clear, educational content for virtual training. Lifecycle messaging is the voice of the product for the user who is not in a sales call. Bring us examples.
• Tool fluency. Customer.io, Braze, Iterable, HubSpot, Notion or equivalent. Comfortable in the data layer (SQL, event tracking, Segment / CDP setups).
• Numerate. You can build a funnel view, read the data, and decide where to intervene. You do not need a data analyst to tell you what to do next. We have engineers to support you building this out.
• AI literacy. You use LLMs in your own workflow. You can speak credibly to a CTO or head of portfolio operations about why our product matters.

Strong signals

• Built a self-serve support hub or knowledge base from scratch.
• Worked at a PE, consulting, or financial services adjacent vendor (AlphaSense / Tegus, Gain.pro, 73 Strings, Canoe Intelligence, Chronograph, Grata / Datasite, Affinity, Dealroom, Allvue, Visible Alpha, PitchBook, Intapp / DealCloud, Enfusion / Clearwater).
• Ran a reactivation program that brought back a meaningful share of dormant accounts with numbers to prove it.
• Have shipped in-product messaging through Pendo, Appcues, Intercom, or equivalent.

Why Junior?

• Top 1% traction: 10x revenue growth in 12 months, $21m run-rate, profitable, half the top 30 PE firms by AUM and most of the major consultancies serving them as clients.
• First-of-its-function ownership. Exceptional performance opens the door to Head of Lifecycle Marketing with a team underneath you.
• High ownership, no micromanagement.
• Equity in a profitable, bootstrapped company.
• Third Space membership (or equivalent of your choice).
• Private health insurance.
• Multiple all-expense-paid offsites per year (recent: Cancun, Crete and Barcelona).
• Office-first culture (5 days in our Farringdon office when you're in London).
• Travel: light, with the occasional team offsite and customer trip.
