On July 22, 2025, Cooler Heads announced that it has closed an oversubscribed $11 million Series A funding round to expand the manufacturing and rollout of Amma™, the only FDA-cleared Portable Scalp Cooling System. The financing was led by Mutual Capital Partners, a Cleveland healthtech-focused venture capital fund, with participation from SHD Partners, Crescent Ridge VC, Cal Innovation Fund, NuFund, Robin Hood Ventures, Golden Seeds, HIP VC, and an unnamed strategic investor. Wilson Sonsini Goodrich & Rosati advised Cooler Heads on the transaction.

The Amma™ system helps chemotherapy patients keep their hair and preserve their privacy, eliminating the disfiguring hair loss that has long been an accepted side effect of chemotherapy. The proceeds from the Series A financing will be used to increase manufacturing capacity, expand the commercial team, and develop the next generation of the product.

The Wilson Sonsini team that advised Cooler Heads on the transaction included Karen Deschaine, Phil McGill, Dani Glazer Signaigo, and Matt Fleming.
