Augment Risk has appointed Brittany Haynes as partner in its MGA practice, effective immediately. Based in London, she joins from Guy Carpenter's GC Access programme business, where she served as SVP and then managing director. She reports to Mark Aylward, partner, MGA.
Haynes is the latest in a sequence of MGA-focused hires Augment Risk has made since late 2025. Magnus Heimann joined in December 2025 to build the European practice, Lucy Carter followed in March 2026 for the US push, and Lee Bonnett arrived in June 2026 focusing on Lloyd's and North American cat-focused placements.
Each has brought a distinct specialism: European coverholders, US programme business, Lloyd's cat MGAs, and now Lloyd's delegated authority with North American programme structuring.
Haynes spent her entire career in the channels that have become central to how reinsurance capital reaches the MGA market. She began in New York in 2012 and moved into facultative reinsurance at what went on to be known as Willis Towers Watson before joining Willis Re's alternative distribution operation, the broker's dedicated unit for delegated authority and programme business.
She joined GC Access in August 2021 as SVP, was promoted to managing director in December 2025, and spent four-plus years working on Lloyd's delegated underwriting authority placements and the structuring of North American programmes. GC Access is Guy Carpenter's programme-focused unit, connecting MGAs and carriers across Lloyd's and North American markets.
At Augment Risk, Haynes will advise MGA clients on capital and reinsurance structures across the same territory. The firm structures transactions around a client's capital position rather than placing off-the-shelf reinsurance products.
The rationale for building a dedicated MGA practice at a specialist reinsurance broker has strengthened considerably over the past two years. Premium ceded by the US MGA market to reinsurers reached US$21.2 billion in 2025, up 18% year-on-year, according to Gallagher Re's 2026 MGA Market Report. As that volume has grown, so has the complexity of the capital decisions behind it. Rated versus unrated capacity, fronting carrier relationships, and cross-border distribution require specialist structuring rather than standard treaty placement.
Augment Risk was founded in mid-2023 with up to US$100 million in backing from private equity firm Altamont Capital Partners. It bound approximately US$1 billion in premium in its first full year and had grown to approximately US$1.6 billion in placed premium by early 2026.
Every MGA hire Augment Risk has made comes from the specialist programme units of established brokers and carriers: GC Access, BMS, Acrisure London Wholesale and Accredited Europe. None came from generalist reinsurance broking backgrounds.
