Accelerant

Accelerant Holdings (NYSE: ARX) operates the Accelerant Risk Exchange, a data-driven marketplace that connects underwriters of specialty insurance risk — MGAs, program administrators, captive managers and retail brokers, referred to as Members — with risk capital providers including insurers, reinsurers and institutional investors. Founded in 2018 and headquartered in Grand Cayman with operations across the United States, Canada, the United Kingdom, Europe and Australia, the company runs three segments: Exchange Services, MGA Operations and Underwriting. Its member platform at app.accelerant.ai delivers AI and machine-learning underwriting products — risk scoring, portfolio risk monitoring, geospatial intelligence, product intelligence, underwriting referrals and bordereaux (BDX) data submission and observability — and the company states that its risk indices plug directly into Member underwriting and policy administration systems via API. Developer documentation is published at docs.accelerant.ai behind Member authentication; the platform publishes an anonymous OpenID Connect discovery document and JWKS at app.accelerant.ai.

Accelerant is listed with 1 API on the APIs.io network. Tagged areas include Insurance, Insurtech, Specialty Insurance, Underwriting, and Risk Management.

Accelerant’s developer surface includes documentation, support, engineering blog, product news, authentication, and 27 more developer resources.

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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/.
