Founders Associate

PF Nexus - Remote-First - 12 Month Fixed-Term

Hello!

We're PF Nexus, a London-based AI-first marketplace connecting renewable energy and AI infrastructure developers with institutional investors, financiers and acquirers across Europe - and we're looking for a Client Success & Operations Associate to join our small, close-knit founding team.

🌍 A little about us

PF Nexus has built a network of 8,500+ professionals and 5,000+ companies across the renewable energy and AI infrastructure space. We're at an inflection point: deal flow is growing, the platform is gaining real traction, and we're building the team to scale it.

We're backed by Rockstart, and were selected as a Winner of Amazon AWS' Fintech Accelerator - the only startup in the Sustainability category to make the cut, chosen by a panel including some of the world's top VCs.

This is one of our most important hires to date, and you'll be working directly with the founders from day one.

💻 About the role

You'll be the human face of PF Nexus for a large part of our subscriber base - the first point of contact for our network of developers, investors and advisors. One day you might be handling a client query in HubSpot, the next you're chasing introduction feedback with our in-house LLM toolset, the next you're drafting a newsletter or setting up an outbound campaign.

It's a broad, hands-on role with real ownership from day one. As we grow and make specialist hires, some of what you do will hand off and new responsibilities will take their place - if that variety energises you rather than unsettles you, you'll thrive here.

🎯 What you'll be doing

Client Support & Engagement

• Managing inbound queries and proactive check-ins with our network of 8,500+ subscribers
• Handling onboarding communications and leading post-churn calls to understand why subscribers leave - and win them back where we can
• Tracking subscription payments and chasing failed payments

Deal Pipeline & Feedback Management

• Keeping our HubSpot introduction feedback pipeline current - stages, notes, and spotting where deals are progressing
• Running outbound feedback sequences and handling responses, working with an LLM-assisted tool to log everything efficiently

Commercial Outreach & Growth

• Running cold outreach and investment campaigns via Apollo
• Nurturing leads from our existing CRM audience and helping identify the right target audiences
• Writing copy that converts - this is a role where writing quality and commercial judgement really matter

🙌 Who we're looking for

• Excellent written English - you'll correspond daily with senior professionals at investment funds, development banks and energy companies
• 2+ years in a client-facing role (customer success, account management, operations or similar) at a B2B company
• Highly organised and self-sufficient - comfortable managing a varied task list without being micromanaged
• A genuine eye for detail, and a bit obsessive about data hygiene
• Comfortable with AI tools (Claude, ChatGPT or similar) as part of your everyday workflow
• Proactive - you spot what needs doing and get on with it
• Happy to pick up new tools quickly (we use HubSpot, Contentful, Stripe, Slack and Loom, among others)
• Based in the UK - we're remote-first for now, meeting periodically in London, with a likely move to hybrid working (2–3 days in a London office) in the next few months

It's a bonus if you've got exposure to renewable energy, cleantech or financial services, or experience running outbound email campaigns or CRM-driven outreach - but neither is essential.

🤝 Our culture

• Mission-driven - everything we do helps get renewable energy and AI infrastructure projects funded
• Small team, real impact - your opinion and drive to succeed count; you'll never be a small cog in a big machine
• Fast-moving and hands-on - the role will change shape as we grow, and we're looking for someone who finds that exciting rather than unsettling
• Remote-first now, moving toward hybrid working in London as the team grows

✨ What you get

£32,500–£37,500 per year, on a 12-month fixed-term contract. Remote-first, with occasional in-person days in London and a move toward hybrid working as we scale.

To apply: send your CV along with a short cover note - no more than a few sentences - on what specifically attracts you to this role and what in your background makes you a strong fit. Generic applications won't be considered.
