Founders Associate

About the role

Rillet's pace is not for everyone. Intelligence is table stakes. To succeed here, you need extreme speed, agency, and flexibility. Successful Rilleteers do not wait for assignments. They internalize a mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for. Work revolves around our customers. Successful Rilleteers are energized by delivering the most important things, even those that weren't in the original plan. In this role, you do not need to be an accountant. But you do need to appreciate the value that our customers can create for their own company when we equip them with the perfect financial tools. Successful Rilleteers love powering the financial core of the world's fastest-growing companies. Who We Need Rillet is looking for a Founders' Associate to work directly with the CEO and Chief of Staff. You will be the connective tissue that keeps high-priority work moving - spotting roadblocks early, solving them before they escalate, and ensuring nothing falls through the cracks. You will operate across a wide range of workstreams simultaneously, supporting the Chief of Staff with analytical horsepower on strategic projects, helping design and improve internal processes, and supporting the CEO day-to-day from drafting communications to making sure key initiatives reach completion. You will need to be highly organized and comfortable with frequent context switching. One hour you're in a spreadsheet modeling a business case. The next you're drafting a note on behalf of the CEO. The next you're figuring out why a cross-functional project stalled and fixing it. This is a high-output role. You will work hard, move fast, and be held to a high bar. In return, you will get unparalleled exposure, accelerated growth, and a front-row seat to building a company. We're looking for a teammate who value in-person collaboration and is within commutable distance of our San Francisco offices (or willing to relocate). Team members are required to work in-office Tuesdays and Thursdays, plus one additional flexible in-office day.

Responsibilities

• Track progress on key initiatives on behalf of the CEO - proactively flagging risks, identifying roadblocks early, and ensuring the right people are unblocked and moving forward
• Prepare internal and external communications on behalf of the founders, including investor updates and board materials
• Apply analytical horsepower across all functions to generate insights that drive decisions - whether that's modeling sales efficiency in GTM, analyzing retention trends in Customer Experience, building headcount plans in HR, or stress-testing unit economics in Finance
• Run operational processes across internal ops functions
• Project-manage initiatives that span multiple stakeholders and require strong follow-through
• Serve as a connective layer across the organization - making sure decisions get made and nothing falls through the cracks
• Who We're Looking For
• 1-3 years of experience in management consulting, investment banking, or a BizOps / strategy role at a high-growth startup
• Proficient with Claude, you have used it extensively and know how to get the most out of it
• A track record of delivering in fast-moving, ambiguous environments with minimal hand-holding
• Executional by nature
• Strong analytical skills: comfortable building models, interpreting data, and turning insights into action
• Exceptional written and verbal communication: you can draft a crisp investor update and a clear internal Slack message with equal ease
• Highly organized with sharp attention to detail, even when juggling multiple workstreams
• Low ego, high ownership
