Xolo Tech Stack

All-in-one business platform for freelancers and solo entrepreneurs

Financial Services City Centre, Harjumaa 51–200 employees Privately Held

Xolo operates a full-stack fintech product for freelancers, combining banking, accounting, tax, and business registration into a single interface. The tech stack reveals a mature, containerized backend (Java/Spring Boot + Kafka/Pulsar + PostgreSQL on AWS EKS) paired with a React frontend, now migrating build infrastructure to Kubernetes—a scaling move that aligns with their stated push into new markets. Active hiring across engineering, finance, and design, plus a recent CFO appointment, suggests they're transitioning from founder-led ops to structured financial and product scaling.
