The startup builds software that helps finance teams recover overdue invoices faster by automating follow-ups, escalations, and payment tracking.
The company already works with more than 20 businesses across five countries, collecting payments from customers in 30 markets. The funding will go toward product development as it expands its accounts receivable platform.
Why now? For growing companies, chasing overdue payments remains a manual slog. Finance teams juggle spreadsheets, email threads, and basic accounting-system reminders — none of which are built for the nuances of collections workflows or customer relationships.
"One sentence kept coming back: 'I hate working with invoices,'" said co-founder Filip Szczeciński. "A process that directly affects their liquidity still depends on manual work."
Szczeciński founded sunbay.io with Dawid Dzierzyński and Nikodem Cabała after hearing repeatedly from finance leaders how much time their teams spent managing receivables. The platform connects to invoice data and automates collections via email, SMS, and AI voice calls, looping in humans only when judgement is needed.
What could go wrong? The space is competitive. ERP giants and accounting platforms already offer basic payment reminders, and larger players could bolt on similar automation. Convincing finance teams to adopt a standalone tool — and integrate it with existing systems — is a classic early-stage hurdle.
Operating across 30 markets also means navigating varying payment cultures, legal frameworks, and communication preferences, all of which add complexity for a small team.
The signal: Kogito Ventures' lead on this round adds a Warsaw-based seed investor to a growing list of Polish funds backing domestic fintech infrastructure. With sunbay.io still at the early stage and already operating across 30 markets, the bet is that accounts receivable automation can scale as a standalone category before ERP incumbents catch up — a window that narrows as cash-flow tooling climbs the priority list for CFOs across Europe.
