Flyntlok Secures $36 Million Growth Investment from Mainsail Partners to Bring AI & Innovation to Heavy Equipment Dealers

ANCHORAGE, Alaska, Oct 9, 2025 (BUSINESS WIRE): Flyntlok, provider of a modern, cloud-based heavy equipment dealer management system (DMS), today announced a $36 million growth investment from Mainsail Partners, a growth equity firm investing in bootstrapped vertical SaaS companies. With this investment and the support of Mainsail AI Labs, Flyntlok will introduce new products and features to help equipment dealers drive efficiencies and uncover new revenue opportunities through AI.

In addition, Flyntlok plans to invest further in its customer success program, ensuring dealers continue to receive the hands-on guidance and service that has distinguished the company.

“Whether they like it or not, equipment dealers are in the data management business: managing millions of part numbers, thousands of models, and constantly changing pricing structures and incentives,” said Sean McLaughlin, founder and CEO of Flyntlok. “When you add in today’s tariff pressures, dealers need every advantage to drive efficiency and protect growth. We’re excited to leverage Mainsail’s deep experience in scaling vertical SaaS businesses, as well as the strategic and technical resources of Mainsail AI Labs, to bring AI and innovation to the dealer market in ways that deliver transformative value for our customers.”

Flyntlok is a specialty, cloud-based DMS purpose-built for various dealer segments including heavy equipment, heavy and medium-duty trucks and outdoor power equipment. The platform was designed and incubated by McLaughlin inside his own dealership, Craig Taylor Equipment, where he leveraged the platform to help grow revenue from $20 million to more than $105 million in 11 years.

Flyntlok helps dealers across hundreds of locations streamline mission-critical workflows such as point-of-sale, purchase and work orders, rentals, transportation scheduling, fleet and inventory planning, while also integrating in real time with QuickBooks and Sage Intacct for general ledger, AP/AR and payroll. The system supports dealers managing equipment of all sizes, from blowers, mowers, and weed trimmers to loaders, graders, excavators, and mining trucks.

“Flyntlok’s dealer-first approach was locked in from inception, as Sean’s experience building and using the platform to grow his own dealership reinforced the power of modernizing business management with intuitive, cloud-based software. Being purpose-built within its vertical, combined with deep OEM integrations and a strong reputation for customer support, sets Flyntlok apart,” said Vinay Kashyap, Partner at Mainsail Partners.

“We see tremendous opportunity to help Flyntlok accelerate innovation, particularly in bringing AI to the industry to create lasting value for dealers, and we look forward to partnering with the Flyntlok team in their growth,” said Anthony Hayes, Principal at Mainsail Partners.

At the upcoming Equip Exposition, held October 21-24 in Louisville, KY, Flyntlok will showcase some of the ways that properly implementing AI within a DMS can help dealers unlock value hidden within their own data, such as surfacing sales opportunities through the Flyntlok CRM, and streamline repetitive processes to help them run leaner, more profitable businesses.
