Warsaw-based firm sunbay.io, which builds an AI-driven receivables automation platform for finance teams, has secured €550,000 from Kogito Ventures with participation from s20 and angel investors, as Vestbee was informed.
- Founded in 2026 by Filip Szczeciński, Dawid Dzierżyński, and Nikodem Cabała, sunbay.io develops software that connects directly to a business’s accounting system and automates the end-to-end invoice collection process.
- This includes monitoring overdue invoices, sending follow-ups across email, SMS and voice, managing escalation rules, and triggering actions based on payment behaviour and risk signals.
- The platform replaces manual collections work typically handled in spreadsheets and email threads. Finance teams set their collection rules and workflows, while the system executes them automatically and provides a live dashboard of all receivables. It also uses payment data analytics to identify invoices at risk of delay and help reduce overdue payments.
- The product integrates with existing ERP, CRM and accounting tools, allowing companies to keep their current systems while automating the operational layer around invoicing and collections.
“As we grew, handling collections started taking up more and more of our time. sunbay.io helped us organise and automate that process, freeing up more than 40 hours a week and allowing the team to focus on more important work,” said Tomasz Stawarski, CEO and co-founder of Tequipy.
Details of the deal
- The fresh capital will enable sunbay.io to expand its AI-powered receivables system by building more autonomous agents that handle end-to-end overdue invoice workflows, strengthening predictive payment behaviour signals, and scaling across additional European markets while further reducing manual workload in finance operations.
