Strategic Partnerships Lead - UK in London

Rillet serves accounting and finance teams, the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight. Rillet is the Agentic ERP built for modern finance teams. We help companies automate the most critical parts of finance, from closing the books and recognizing revenue to consolidating entities and reporting to investors. More than 600 companies run on Rillet, including Mercor, Scribe, and Function Health, and we partner with leading accounting firms including EY and KPMG.

We’re building in one of the largest software markets in the world, with the momentum to match. Rillet has raised more than $200M, is valued at $1B, and is backed by Sequoia, a16z, ICONIQ, Bain Capital Ventures, Oak HC/FT, and other leading investors. We’re using that backing to build the financial infrastructure for the next generation of companies and help every business run its numbers at the speed of AI.

Rillet’s pace is not for everyone. Intelligence is table stakes. To succeed here, you need extreme speed, agency, and flexibility. The people who thrive at Rillet do not wait for assignments. They internalize the mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for. Our work revolves around our customers. The people who succeed here are energized by delivering what matters most, even when it was not part of the original plan.

Rillet is built on deep accounting expertise, and it takes people from many disciplines to build a category-defining company. You do not need to be an accountant to thrive here. You do need to care deeply about the problems we solve and the impact our customers can create. Together, we combine the precision of accounting with the speed, creativity, and ambition of AI‑native software to power the financial core of the world’s fastest‑growing companies while redefining what finance teams should expect from their software.

Rillet is hiring its first partnerships leader in the UK. You will kickstart our partner motion in the market from day one: choosing where to start, signing the first partners, and building results and momentum so we can staff up a team around you. This is a founding, high‑agency role that will span all three of Rillet's partner channels in the UK:

• Accounting & Advisory: CPA, chartered accountancy, and ERP consulting firms that recommend and implement Rillet for their clients
• Private Equity & Venture Capital: investors who back finance‑led high growth companies and want to tool them with the best available technology
• Technology: the fintech and Office of the CFO software ecosystem that integrates with Rillet and co‑sell with us

You will work with partner executives on vision and business‑case creation, and with front‑line leaders on execution. You will work closely with the US partnerships leads for each channel, who will share playbooks, frameworks, and introductions, and with Product, Sales, Marketing, Solutions, and Customer Success to make every partner relationship turn into pipeline and revenue. You will build on our existing partnerships in the US – with firms such as the Big 4 and top PE firms – and expand our presence in their ecosystems in the UK. This is a highly visible role internally and externally. What you build in the UK becomes the template for how Rillet launches partner programs in new markets.

What You'll Do

• Launch the UK partner motion: Create a market map of key partners and channel‑specific motions, and execute relentlessly to get early wins
• Generate revenue day 1: Partnerships is a critical go‑to‑market play for Rillet, and it’s important we are commercially oriented from the start
• Develop Rillet’s value exchange: Our partnerships are built on trust and reciprocity; you will identify what major partners care about and align Rillet’s plans to bring them value
• Expand core capabilities and capacity: Work with partners to deepen our product capabilities and our implementation capacity in the UK
• Establish Rillet as the market leader: Build alliances with the top firms and technology companies, and notable individuals, to win mindshare among addressable clients.
• Host and attend industry events: Build relationships and presence in the UK and become the face of partnerships for the market
• Enable Rillet’s GTM functions to work seamlessly with partners: Co‑sell, implementations, integrations, customizations – wherever a partner can help us win, Sales, Marketing, Solutions, and Product should know whom to go to and how
• Provide critical product feedback from the front lines: Rillet’s partners are top notch. They understand customer needs, and our job is to bake their feedback into everything we do

What We're Looking For

• 6+ years of relevant experience in strategic partnerships at a high‑growth B2B software company, or at a top finance‑focused private equity firm
• Background in analytically rigorous professions – investing, management consulting, investment banking, or product strongly preferred
• Track record of launching and scaling partner programs from scratch, ideally as a first or early hire in a new market
• Demonstrated ability to turn partnerships into real commercial outcomes: partner‑sourced and partner‑influenced revenue, not just relationships
• Experience with at least one of our channels (accounting and ERP consulting firms, PE / VC investors, or technology and integration partners), and the curiosity to learn the other two quickly
• Established network in the UK finance, accounting, or software ecosystem is a strong plus
• Ability to build trusted relationships with C‑level and equivalent executives
• Proven track record of thriving in ambiguity: creating structure, taking action, and driving measurable results
• Track record of cross‑functional collaboration and impact
• Strong internal drive and low ego, with a team‑first, growth mindset. Some call this an "Athlete" mentality
• Willingness to travel across the UK and Europe, and to the US as needed

Life at Rillet

• Grow with us. Take meaningful ownership, expand your scope, and make an impact as Rillet scales.
• Competitive pay and meaningful equity. Be rewarded for the value you help create.
• Benefits that support you. We offer competitive benefits designed to support your health, wellbeing, time away from work, family, and long‑term financial goals.
• Better together. We value collaboration, connection, and spending meaningful time together as a team. We regularly create opportunities to connect through team meals, events, and company gatherings.
