Tremor

Tremor Technologies operated a programmatic "smart market" for wholesale risk and reinsurance, applying intelligent market design, auction technology, and optimization to match risk with capital and price and place reinsurance contracts far faster and cheaper than traditional negotiated markets. Founded in 2016 by Sean Bourgeois and later based in Greenwich, Connecticut, the platform ran auction-style placements for insurers, brokers, reinsurers, ILS funds, and Lloyd's syndicates, and added Tremor Wordings to digitize contract negotiation. Backed by Anthemis (lead), W. R. Berkley, Nephila Capital, and Markel, Tremor's assets were sold to W. R. Berkley Corporation in September 2023 and the standalone public marketplace site (tremor.co) is no longer live.

Tremor is profiled on the APIs.io network. Tagged areas include Company, Reinsurance, Insurance, Insurtech, and Marketplace.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/tremor: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
