Global Air Cylinder Wheels (GACW), a Phoenix-based engineering company known for its Air Suspension Wheel (ASW) technology, has launched its third equity crowdfunding campaign on StartEngine. The company aims to raise $3.2 million under Regulation CF as part of its funding strategy.
This GACW crowdfunding campaign follows a successful raise of $1.47 million in May 2025 through Dealmaker, which funded fabrication and delivery of ASWs for a trial with a major U.S.-based iron ore mining company. That trial is expected to conclude by the end of 2025.
GACW Crowdfunding Campaign: Capital Strategy And Growth Goals
The campaign forms part of GACW’s broader plan to secure up to $15 million over the next 18 months. Funds will accelerate commercialization, fulfill purchase orders, and expand global operations.
Currently, GACW has over $6 million in anticipated purchase orders from six mining companies in the U.S., Canada, and Australia. The company is also generating approximately $4 million in revenue from industry contracts and trials.
“Investor confidence in GACW is based not just on our vision, but on tangible progress,” said Harmen van Kamp, CEO of Global Air Cylinder Wheels. “Our StartEngine campaign provides both new and returning investors an opportunity to join us as we execute our plan to scale production, fulfill significant purchase orders, and disrupt a $30 billion OTR tire market in a way that benefits both the industry and the environment.”
The new raise will complement a planned Regulation A+ campaign, GACW said. GACW holds 75 issued patents with more than 120 pending internationally. Its ASW is a non-pneumatic, mechanical wheel made primarily of steel, with in-wheel suspension and damping through nitrogen-filled air cylinders and integrated dampers.
Financial And Strategic Updates
In July, GACW completed its 2024 financial audit with a clean opinion. The company also secured $275,000 in short-term stakeholder loans during Q2. GACW entered advanced discussions with an Australian engineering firm for a potential strategic investment. It opened dialogue with multiple investment groups.
GACW said the crowdfunding campaign marks a step in securing capital to deliver ASWs to the mining industry. It wants to expand into the $30 billion OTR tire market.
