Submit your project to get started!TransactionLink automates KYB and KYC onboarding processes by orchestrating multiple data provider checks into one seamless workflow. We recently spoke with Kamil Skłodowski to learn how this infrastructure is helping financial institutions reduce verification costs and streamline compliance operations.What does TransactionLink do? And why is now the time for it to exist?TransactionLink automates KYB and KYC onboarding, cutting verification costs by 60%. The platform instantly verifies customers and orchestrates checks across multiple data providers in a single workflow, while a unified dashboard lets teams investigate exceptions without switching tools. Now’s a good time for TransactionLink to exist because increasing regulatory pressure and high operational costs are forcing financial institutions to seek more scalable, automated compliance infrastructure.What is your traction to date?TransactionLink is a B2B compliance infrastructure product — we don't track a consumer-style "monthly visitors" metric, since our users are compliance and risk teams at financial institutions who integrate the platform rather than a public-facing site. Reach is better measured by verification volume processed on behalf of our customers' end users.Who does TransactionLink serve? What’s exciting about your users and customers?TransactionLink is built for compliance and risk teams at financial institutions, fintechs, and lenders who need to verify business (KYB) and individual (KYC) customers before onboarding them. The primary users are compliance analysts and operations teams who configure verification workflows and review flagged exceptions, plus the engineering teams who integrate the platform into onboarding flows via API.What technologies were used in the making of TransactionLink? And why did you choose the ones most essential to your tech stack?To build a reliable and fast compliance orchestration engine, TransactionLink leverages a robust tech stack that includes Bright Data, Neo4j, and AWS. Neo4j is particularly essential for mapping and querying complex corporate structures and relationships during KYB checks, while AWS provides the highly secure, scalable cloud infrastructure necessary for handling sensitive financial data.Around the web, who’s been noticing TransactionLink?TransactionLink is gaining attention from B2B enterprises and successfully proving its market fit through key integrations. Notably, their work with Pliant serves as a strong case study, demonstrating how their infrastructure effectively automates onboarding and reduces operational friction for financial clients.What excites you about TransactionLink's potential usefulness?KYB/KYC compliance is one of the most repetitive, manually-checked processes in financial services — every institution rebuilds the same "call five data providers, reconcile the results, flag the mismatches" logic in-house. A workflow engine that orchestrates those checks and centralizes exception handling turns a process that today eats analyst-hours and slows customer onboarding into something that's fast, auditable, and consistent across cases — which matters both for cost and for reducing the compliance risk of a missed check.Meet our sponsorsBright Data: Bright Data is the leading web data infrastructure company, empowering over 20,000 organizations with ethical, scalable access to real-time public web information.
