Sunbay.io Raises €550K in Funding From Kogito Ventures

The company helps finance teams collect overdue invoice payments more quickly. It already serves more than 20 businesses across five countries and helps them collect payments from customers in 30 different markets.

For many growing companies, chasing unpaid invoices is still a slow and manual process. Finance teams often have to track overdue payments, send reminders, handle special cases, and decide when to escalate issues using spreadsheets, emails, and basic accounting tools.

Although accounting and ERP systems can send standard payment reminders, they are not designed to handle collections based on each company's specific processes and customer relationships. As a result, businesses still spend a lot of time manually managing overdue payments, which can affect cash flow.

In our conversations with CFOs and CEOs, one sentence kept coming back: 'I hate working with invoices.' It wasn't that companies didn't know how to collect their receivables. The problem was that a process that directly affects their liquidity still depends on manual work. We built sunbay.io so that companies can automate this process on their own terms and bring the team in only where human judgement is actually needed, said Filip Szczeciński, co-founder of sunbay.io.

sunbay.io was founded by Filip Szczeciński, Dawid Dzierzyński, and Nikodem Cabała after they spoke with finance leaders and discovered that teams were spending a huge amount of time managing unpaid invoices and overdue payments.

To solve this problem, they built a platform that automates much of the collections process while still allowing finance professionals to step in and make decisions when human judgment is needed. This helps companies save time, improve cash flow, and reduce the manual work involved in managing receivables.

sunbay.io connects directly to a company's invoice data and automatically manages the payment collection process based on the company's own rules and workflows.

The platform follows up on overdue payments through email, SMS, and AI-powered voice calls. It can also handle escalations and provides customers with a branded payment portal.

Finance teams only need to get involved when a situation requires human judgment or a specific decision, helping reduce manual work and save time.

sunbay.io is now adding more advanced features, including predictive insights and additional automation. The platform can already identify customers who may be at risk of late payments by analyzing credit scores and payment behavior. In the future, AI agents will automate even more tasks, analyze payment data, and help finance teams make faster and better decisions.
