Market Lane Insurance Group is pushing the boundaries of traditional insurance underwriting, building a world-class, diversified business at scale. With the help of Macquarie Business Banking’s deep understanding of insurance businesses and tailored transactional banking suite, Market Lane is creating a blueprint for independence and entrepreneurship at scale.


Australia’s current insurance landscape holds unique challenges for managing general agencies (MGAs). In a competitive market, businesses need to build an identity while managing the risk of handling large sums of international payments and client funds. This environment demands more than a traditional bank; it requires a specialist, equipped for the speed, scale and complexity of a modern underwriting business.

From start-up to scaled success

Founded by David Porteous in 2019, Market Lane is a house of insurance brands, each specialising in a distinct niche within the commercial insurance market.

What began as a two-person start-up, born from an idea in a Manly café, has grown into a thriving international business with 12 distinct brands and 75 staff, a trajectory fuelled by a philosophy of empowering experts with the independence to own their niche.  

“I knew I was an MGA guy at heart – what I loved to do most was coming up with a product idea, writing a business plan, and getting it to market,” says Porteous, Group Managing Director. “But I also saw that traditionally, brokers often perceived MGAs as being mono-line. The vision for Market Lane was to solve that.”

“Like walking through a great marketplace with different vendors, each brand would be a specialist, making it easy for a broker to know who to turn to for a specific need.”

“It gives our brands a clear identity. We try and identify the niches in the market where can deliver for our insurers, and where we can add value to our brokers and their clients.”

Now, Market Lane’s sights are set on the future, with a focus on:

  • Further growth, supported by trusted partners
  • Streamlining the back office to enable scale
  • Planning for succession
“the Business Banking team genuinely understand what we do.”

The bank for insurance

Market Lane always planned to make the switch to the bank that understands insurance businesses.

“We knew a better home for the future of our business was Macquarie Business Banking,” says Porteous. “And that was because the Business Banking team genuinely understand what we do. That is one of, if not the main differentiator – Macquarie Bank genuinely understands our business.”

Deep industry understanding is the cornerstone of Macquarie Business Banking’s approach to insurance banking. For a scaling business like Market Lane, this means having a dedicated relationship team that speaks their language, and a suite of products tailored for the industry’s operational nuances. This specialist model supports businesses as they mature, from structuring capital for growth, all the way to succession planning, helping founders realise the full value of their life’s work.

“Because Macquarie gets what Market Lane does, it gives us a lot of comfort that if capital is ever on the cards, we’re with the right bank. Having those conversations with our relationship manager is far easier than with a bank who doesn’t understand our industry.”

With confidence that their banking team are behind them on their growth journey, Market Lane are gearing up their back office in preparation for future scale.

 

Streamlining for scale

Porteous and Michael Atkinson, Group Chief Financial Officer, know that Market Lane is on a rapid growth trajectory, and have put levers in place to optimise and support operations as the business scales.

“The integration of Macquarie’s technology platform into our platforms – claims, CRM, underwriting, accounting – is key to our business’ efficiency and security,” says Atkinson.

“We need to pay people on the other side of the world a lot of money, every month, from funds that aren’t ours,” says Porteous. “Macquarie understands the risk involved, the quantum of payments we need to make, the variation of cash flow month to month, the different staff members that need access to these processes with different authorities. It’s very robust.”

This became particularly critical when Market Lane brought their claims management in-house, a move dramatically increased their business growth, and its operational complexity. The ability to follow multiple accounts through the claims handling process and open new accounts regularly and rapidly became critical.

“I genuinely don’t think we could have achieved what we have with claims without Macquarie Bank’s support,” says Porteous. “Macquarie’s capabilities have allowed us to make our banking and operations work for our business, tailor it to the way we run things, rather than the other way around. That has been outstanding for our team.”

“It means our banking grows with us.”

“The integration of Macquarie’s technology platform into our platforms …is key to our business’ efficiency and security”

A relationship to rely on

“When you’re growing at the rate Market Lane is growing, a dedicated relationship team is really valuable,” says Atkinson.

“The insights and ideas-sharing we receive is unmatched in the banking industry,” says Porteous. “We get opportunities to attend meetings and events where we have some wonderful discussions with other businesses and experts in our industry.”

“And if something is going wrong or we need help, I have a direct mobile number I can call to speak to someone I know and resolve issues quickly.”

“If you want a bank that genuinely knows our industry at a deep level – and not just how it operates, but who’s in it, the big players, the language of the industry – with total ease of relationship, transacting, and doing business, then Macquarie Bank is who you have to work with.”
