Upflow is the Financial Relationship Management (FRM) platform that helps B2B finance teams collect smarter and get paid by their customers faster, with AI agents working alongside the team.

Today, the order-to-cash process is mission critical for businesses, yet it remains fragmented across tools, teams, and workflows. Upflow brings this entire process into one system — four products covering the cycle from invoice to cash (Insights, Collections, Payments, and Cash Application), with AI agents that work alongside the team and a shared intelligence layer underneath.

We serve 500+ companies across 30+ countries, including Vercel, Lattice, and Productboard, and are backed by leading investors including Y Combinator, Hedosophia, Hexa, and Lorimer. With teams across the US and Europe, we're building a category-defining company at the intersection of finance, payments, and AI.

Reporting to our Director of Operations, you will:

• Manage and prepare communication for external stakeholders, including investor reporting and communication

• Prepare, coordinate and take part in top management and company-wide meetings, and lead our Global Weekly Team Meeting, ensuring proper follow-up and alignment

• Coordinate strategic planning activities, including the preparation and facilitation of quarterly OKR planning sessions

• Monitor progress toward company goals, owning key business metrics and tools (e.g. leadership cockpit, business metrics tracking) to ensure transparency and support decision-making

• Execute ad-hoc, cross-functional projects, including topics coming directly from our founder, to support different functions of the business

• Proficient with spreadsheet applications, able to both handle and process large sets of data, and get into the details.

• Proficient with slide presentation, able to craft compelling decks adjusted to different audiences.

• Exceptionally organized and capable of managing multiple projects simultaneously.

• A strong communicator, comfortable interfacing with stakeholders at all levels.

• Proactive and eager to take on responsibilities, with an eye for detail and a commitment to excellence.

Here's what you’ll find at Upflow:

• Defined pathway — This is a structured 6-month internship designed to immerse you deeply in the workings of Upflow’s CEO office.

• Truly international culture — English is our primary working language across both our Paris and NYC offices: in every meeting, document, and Slack message. Our team brings together 10+ nationalities, and that diversity is core to how we build and think.

• Clear principles, real ownership — We operate by a set of defined operating principles that shape how we work together day-to-day: radical ownership, working in small batches, mastering our craft, and having each other's back. Hands-off management, strong autonomy.

• A rare business milestone — We turned breakeven in 2025 while growing 70% YoY: a combination you rarely see in tech. As our business model evolves toward efficient, profitable growth, the next phase will be one of the most exciting chapters yet.

• Learning opportunity — Strong focus on learning and growing through education and professional development in hard and soft skills.

• Offsites & community — Regular team offsites, meetups, and strong connections to the startup ecosystem.

1 - Screening call with Louis, Director of Operations

It’s a discussion with your future manager. We’ll get deeper into your expertise and know-how. We’ll also give you a clearer view of what your day-to-day in that role is like. It’s a good opportunity to see if you foresee yourself working at Upflow.

2 - Home assignment

Your time to shine! You’ll be given a home assignment. Yes, it is designed to assess your skills. But it’s also designed to give you a better taste of what being part of Upflow is like. Again, hiring is a two-way street! Ultimately: we believe assignments are a great way to control our biases. We care about what you do — not your schooling, your social background, or how you identify.

This home assignment is expected to take you no more than 2-3 hours of work.

3 - Home assignment review

Louis will debrief your case with you. Hiring managers at Upflow are looking for team players: taking and giving feedback is key to thriving with us!

4 - Team interviews

You'll be invited to meet (A) our current Founder Associate, so you can discuss what being in this role is and feels like, and (B) our Finance Director.

5 - Founder interview

Meet with Alex, our co-founder & CEO. He will tell you everything about Upflow’s vision and values. It’s a privileged moment to ask questions, too.
