Dec 2024Series AM Ventures (lead); Boulder Ventures; Biotechnology Value Fund$25MAmbrosia Biosciences Inc. is a Boulder, CO-based privately held drug discovery company developing orally delivered, small molecule-based therapies targeting obesity and other metabolic disorders, focusing on incretins and class B GPCRs as alternatives to injectable GLP-1 agonists like semaglutide. Founded by Nick Traggis (President and CEO) with Kyle Lefkoff (Boulder Ventures Founding Partner) as Executive Chairman, the company launched in March 2024 and recruited scientists from the former Array BioPharma/Pfizer R&D campus in Boulder, leasing space there and expanding to 20 full-time researchers and seven contractors by December 2024. The Series A financing began with a first closing of $16 million on August 20, 2024, led by BVF Partners and Boulder Ventures to scale drug discovery programs and lab operations. A second closing on December 10, 2024, raised an additional approximately $9 million (via 9 million Series A preferred shares at $1 per share), led by Merck (known as MSD outside the US and Canada), with participation from BVF Partners and Boulder Ventures, bringing the total Series A to $25 million. Proceeds from the full round support initiation and expansion of in-house preclinical development operations at the Boulder facility, transitioning from CRO partners to accelerate medicinal chemistry and biology efforts ahead of in vivo data release planned for Q3 2025 and future Phase 1 human trials funding. Ambrosia had made progress with CROs prior to in-house scaling. Legal counsel was provided by Wilson Sonsini Goodrich & Rosati.
