IT Services and IT Consulting Boston, MASSACHUSETTS 51–200 employees Founded 2013 Privately Held

Flexspring builds integrations that sync employee data across HR systems such as Workday, Oracle HCM Cloud, ADP, UKG, Dayforce and BambooHR. Its Java/Spring and Groovy core with JMS messaging, MongoDB, Redis and Elasticsearch on AWS points to an event-driven integration engine rather than a services-only shop. Accelerating hiring that spans engineering, ops and marketing, plus an audit of AI-assistant visibility, suggests a push to scale the platform and its discoverability.
