The fastest way to quote commercial risks

Underwriting,
accelerated.

The modern underwriting stack starts with speed to quote. Marin operationalizes your pricing logic, automates quote generation, and delivers a broker experience that wins placements.

In E&S and specialty, being first is everything.

Brokers send submissions to multiple markets at once. The first clean quote wins the bind. Marin turns submissions into quotes using your existing pricing logic and delivers them as beautiful digital quotes brokers can review and share instantly.

Why carriers adopt Marin

Quote in minutes, not days

Marin eliminates the manual steps between receiving a submission and sending a quote. What used to take hours now happens automatically.

Handle more submissions per underwriter

No more re-keying data or assembling documents by hand. Underwriters focus on risk selection while Marin handles the quoting mechanics.

Win more placements with brokers

Digital quotes brokers can open, review, and share with clients instantly. No attachments. No back-and-forth.

Three capabilities. One quoting engine.
