Who we are

A Managing General Agent that built its own engine.

We hold delegated authority from a panel of respected insurers to quote, bind and administer cover on their behalf — and we run it all on BONUS, a platform we own end to end.

BONUS was built from the broker’s side of the desk. The instant quotes, the branding, the client map, the real underwriters behind referrals — all of it exists to help you place more of the right business, faster, and keep your clients yours.

How it works

Built for brokers, not for us.

Dynamic client mapping

Your whole book, at a glance.

Every client, renewal and opportunity on one live map — see where your book is, catch renewals before they lapse, and grow the areas that work.

★ The feature test brokers tell us they love
Quick Quote as standard

Know in seconds.

Quick Quote tells you instantly whether a risk fits — so you never spend five minutes on a submission just to get a decline.

✓ Fits appetite — price in seconds
White labelling

Your brand on it.

Quotes, schedules and emails go out under your firm’s branding, not ours. To your client, it’s your service.
