Founder Associate (Internship)

About Upflow

Upflow builds the reference cash collection platform to help B2B companies get paid faster, more predictably, and with stronger customer relationships.

Today, the order-to-cash process is mission critical for businesses, yet it remains fragmented across tools, teams, and workflows. Collections, payments, and reconciliation are often manual, reactive, and disconnected from the rest of the business. Upflow brings this entire process into one system — combining data, agentic automation, collaboration, and financial services to turn receivables into a predictable and scalable engine.

We serve 500+ companies across 30+ countries, including Vercel, Lattice, 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.

Recruitment process

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 for what you do; not your schooling, social background, or the gender you identify yourself to. This home assignment is expected to take you no more than 2-3 hours of work.

3. Home assignment review & Team interview

   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!

   Our current Founder Associate will join this meeting, so you can discuss what being in this role is and feels.

4. 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.
