Launch your own MGA

Become a market challenger in weeks, with the backing of a USD 2bn global insurance group. You write the business. We'll take care of the rest.

Your MGA could be next...

Rent your book or own it

Every year, successful underwriters build books worth millions in enterprise value.

In most businesses, that value stays with the company.

Synergy gives you the opportunity to build a business where the value you create becomes something you own, creating long-term equity alongside your underwriting success.

Your expertise stays the same.

The ownership doesn't.

Your unfair advantage from day one

  • Work faster with automation removing low-value tasks

  • Make better decisions with real-time data and insight

  • Operate on one connected platform — no fragmentation, no duplication

  • Scale without being held back by systems or process

Independent. Founder-led. Built for entrepreneurs like you.
