Company context
Accelerant was founded in 2018 by three industry veterans with over 100 years of collective experience in the insurance and reinsurance industries. They experienced first-hand the structural inefficiencies and fragmentation of the insurance market. There were too many intermediaries operating across siloed entities, resulting in a lack of customer prioritization and excess costs. Antiquated technology, poor data quality, and insufficient transparency has led to information asymmetries, inaccurate pricing, misaligned incentives, and inconsistent capital availability. Our founders were determined to build a platform to solve these issues. By democratizing data and aligning incentives in a single platform, Accelerant strives to deliver better outcomes for all Risk Exchange participants.
