Froda has supported 150,000 businesses across seven markets and funded approximately $3.45 billion since launch. Oliver explains how Froda uses retail deposits, automated underwriting, and embedded partnerships with banks, fintech companies, payment providers, and software platforms to scale its lending operation. Listen to learn: • How Froda makes money on an average loan of just $23,000 • Why its banking license and retail deposits create an advantage • How it prices loans at approximately 16% APR while managing credit losses • Why embedded lending helped Froda expand across Europe • How the company built a roughly $500 million active loan book

Carl Turner, founder of Swipe.by, built an AI marketing platform for restaurants to $3.5M ARR growing 400% year-over-year — with $0 spent on ads and every customer closed by a rep knocking on doors. He breaks down the exact rep comp plan (6 locations/month, $6K ACV, 30–40% commission), why he took $450K from Founderpath instead of Stripe, and why he gives away websites and online ordering for free. Then he turns down a $15M cash offer and explains the 2x liquidation preference math that could leave a founder with nothing.

Raphaël Boukris is the co-founder and Chief Revenue Officer of Didomi (didomi.io), the Paris-based consent management platform that helps enterprises comply with GDPR, CCPA, and privacy laws worldwide. Roughly 2% of all global web traffic passes through Didomi's SDK, and the company processes billions of consent decisions every month for customers including Bloomberg, Sky, and Adyen. In this interview, Raphaël breaks down the full financial history on the record: three funding rounds, two acquisitions, and a majority sale to private equity. He raised under €300k from angels, then €5m from Breega in late 2019, then a €34m ($40m) Series B led by Elephant and Breega in summer 2021 — priced, he says, at above a 10x ARR multiple. Eight months later the market collapsed. He never burned through the money. In April 2025, Marlin Equity Partners took majority control, and Didomi immediately acquired Addingwell and Sourcepoint. Today the group does $40–60m ARR across 3,500 customers with fewer than 200 employees, and has at least one customer paying over $1m per year. What we cover: (01:02) What Didomi actually sells, and why every cookie banner in Europe is a business (01:51) Why roughly 2% of global web traffic runs through their SDK (02:12) Processing billions of consents per month — and who is not the customer (03:00) Pricing on monthly unique visitors, and why AI agents and bots are breaking that model (04:32) The Addingwell acquisition: a few million in ARR, a few thousand euros ACV, profitable enough to pay dividends (05:10) Why he bought a second product instead of building one (06:56) Every round, in order: sub-€300k angel, €5m Breega, €34m Series B (07:50) Above a 10x multiple in 2021 — and how he ran Elephant through a roadshow to get it (09:44) Secondaries in the Series B, and managing a team whose options went underwater (10:06) The year he crossed $1m ARR, and the year he crossed $10m (12:18) The question he answers "absolutely not" — was he ever close to shutting it down (13:09) What growth equity actually pays in 2025, and the range he'd give (14:22) Buying Sourcepoint, a company that had raised $48m, for its ACV and its US enterprise base (15:07) 3,500 customers, one paying over $1m/year, under 200 people (16:44) The combined group revenue number: $40–60m ARR Full metrics, funding history, and revenue timeline: https://getlatka.com/companies/didomi.io  

Stéphane Donzé has bootstrapped AODocs and Talarian to a combined $60m in 2026 revenue without raising capital. His top three customers each pay more than $2m per year, including Google, which pays him millions annually to control the documents behind its data center builds. He funded fourteen years of R&D off a cloud consulting business, never burned more than $200k in a month, and has fielded private equity calls four times a week declining $600m offers. 

He bootstrapped to $16.5m ARR selling software to 2,000 dental offices. Zero dollars raised, 24% EBITDA, and $1.5m in free cash flow last year. COVID cut him back to $2m in 2021; he's added $14.5m since, charging $13k per dental office per year. When I asked what happens if Henry Schein shows up with $180m cash, he gave a surprising answer.
