Alex Louisy usually sits on the other side of the mic. As co-founder and CEO of Upflow, he co-hosts The Growth-Minded CFO alongside Lauren Pearl, asking finance leaders about the decisions that shaped their careers. In this episode, the two switch seats. Lauren interviews Alex about the company behind the podcast, and the story that comes out of it explains why Upflow spent eight years walking away from the product it set out to build in favor of a category nobody had named yet: Financial Relationship Management, or FRM.

The problem wasn't bad payers, it was the process

When Alex started Upflow in 2017, he wasn't trying to build a collections company at all. Coming from an engineering and finance background, he had been watching consumer lending get more dynamic in the US, and wanted to bring that same model of financing to B2B companies in Europe.

So he started talking to CFOs and business owners about short-term financing. The conversations kept leading to the same place. Companies wanted financing to bridge the gap between paying their own bills and getting paid by their customers, and that gap existed because getting paid was, and still is, slow.

"I started having this intuition that the problem was not really about bad payers and people who do not want to pay, but more around the process of doing it," Alex says.

That reframe changed everything. Building a financing company meant licenses, capital, and risk. But the process problem underneath it, structured accounting data getting flattened into a PDF, emailed from a no-reply address, then manually re-entered into someone else's system, was still unsolved in 2026 the same way it was in 2017. Upflow was born to fix that process, not to finance around it.

The moment a CFO said the quiet part out loud

A few years in, Alex kept coming back to a comment from the CFO of Gem, one he now refers to as one of the most formative conversations of his career.

"We spend an enormous amount of money, energy and resources at making every touch point of our customer relationship amazing," the CFO told him. Then came the part that stuck: "The moment we send them an invoice, it's a miserable experience for them."

It was a small comment with a big implication. Companies were obsessing over every part of the customer journey, prospecting, onboarding, QBRs, except the one moment where money actually changes hands. That invoice usually arrived unbranded, from a no-reply inbox, as a PDF with no clear way to pay it. Alex started treating that gap as a design problem, not just a finance problem.

Why "AR Automation" was never the right name

As customers put Upflow to work, they described it back to Alex in language he wasn't expecting. Not automation language. Relationship language.

"This is not an AR automation tool, this is not a tool to send reminders," customers told him. "You guys have built a CRM for our accounts receivable."

That comparison mattered. Sales teams stopped running leads through spreadsheets once CRM existed as a category. Nobody would suggest going back today. But finance teams were still handing their AR managers a version of exactly that spreadsheet, and calling it a process.

The existing category, AR Automation, only ever described part of the job: reminders sent faster, invoices processed more efficiently. It said nothing about the sales rep who just closed the account, or the CS team managing the renewal, or the fact that collecting cash well is a collaborative, cross-functional discipline, not a finance-only task. "That's why we decided to create this entire new category," Alex says. Financial Relationship Management became the name for the fuller job: managing the entire financial dimension of the customer relationship with the same intentionality sales brings to pipeline and CS brings to retention.

Why payments had to be part of the story

Naming the category was one thing. Owning it meant Upflow couldn't stop at collections. Alex points to the consumer world as the clearest evidence of what B2B was missing: one-click checkout, saved payment methods, autopay, all the infrastructure that makes paying a bill frictionless when you're a consumer.

None of that existed for B2B invoices. "Have you seen a CFO thinking about the payment experience in the B2B space this way?" Alex asks. Mostly, no. Companies send invoices without even attaching payment instructions, then wonder why they don't get paid on time.

Bringing a branded, B2C-grade payment experience into Upflow wasn't a side feature. If FRM means owning the entire financial relationship, the payment moment itself has to be part of the platform, not handed off to a generic third party.

What AI changes, and what it doesn't

Asked about AI, Alex draws a clear line between the categories of hype and the categories of substance. Plenty of companies now market themselves as AI-native AR, and plenty of CFOs walk in wanting to buy AI without knowing exactly what problem it solves.

"The FRM positioning that we have... AI is not really changing this," Alex says. "AI is mostly getting to the next level in terms of automation." Where AI genuinely helps is in parsing the unstructured mess of collections work, emails, calls, scanned checks, and in running autonomous collection cycles for lower-stakes accounts.

But automation without trust isn't a solution. "You're probably not going to put your biggest customer... on autopilot with an agent just answering without any control," he says. The real question isn't whether a company can build agentic collections. It's whether finance teams can trust what those agents do, and that trust depends on the same foundation FRM was built on: context, coordination, and clean data across teams.

What's next

Eight years in, Alex doesn't see Upflow's biggest competitor as another AR tool. It's CFOs who haven't been introduced to the category yet. He points out that no sales team runs without a CRM and no finance team operates without expense management today, yet a striking share of the companies Upflow talks to are still running collections out of spreadsheets.

The ambition is to become the household name for the category, the way Bill.com became synonymous with AP. That means continuing to push adoption of e-invoicing and online B2B payments, and continuing to make the case that getting paid deserves the same rigor as getting the sale in the first place.
