How we got here
Crosstie emerged from Harvard University's Innovation Lab with a simple question: What if claims workflows could be both more efficient and simpler?Our founders combined expertise in behavioral science, operational excellence, and technology to build a platform that reimagines how claims work. We studied what actually drives claim outcomes: clear communication, proactive guidance, early intervention, and seamless coordination across all parties.The result is the most configurable and comprehensive workflow orchestration platform in insurance.
Proven outcomes
Our customers realize 74% accuracy predicting litigation risk 3+ weeks in advance, up to 25% reduction in total direct claim costs, 4+ hours saved per adjuster per week, and 10x higher claimant engagement than traditional portals.
Who we serve
Forward-thinking carriers, TPAs, self-insureds, MGA/MGUs, and ancillary service providers who recognize that managing multiple point solutions creates more problems than it solves. Organizations that want comprehensive automation without sacrificing configurability.
Backed by industry leaders
We're grateful to be supported by MassMutual Ventures, General Catalyst, Unusual Ventures, and insurance industry veterans who understand what it takes to improve claims operations at scale.
