Ambrosia Raises $100M for Next-Gen Small Molecule GLP-1 Drugs

The Colorado biotech aims to surpass first-generation oral GLP-1 pills with its AI-powered molecule design platform.

Ambrosia Biosciences has raised $100 million in a Series B funding round to advance its pipeline of small molecule GLP-1 agonists, an alternative to the current peptide-based drugs like Ozempic and Mounjaro. The company plans to use the funds to initiate a Phase 1 study of its lead asset and further develop its broader cardiometabolic portfolio, which also includes candidates targeting GIP and amylin pathways.

Why it matters

While peptide GLP-1 drugs have become the dominant approach, Ambrosia believes small molecules offer key advantages like improved oral bioavailability and manufacturing. As the field evolves beyond first-generation molecules, Ambrosia aims to leverage its AI-driven platform to design differentiated small molecule GLP-1 agonists with enhanced potency and combinability.

The details

Ambrosia's $100 million Series B round was co-led by new investors Blue Owl Healthcare Opportunities, Redmile and Deep Track Capital. The company will use the funds to advance its lead small molecule GLP-1 agonist into Phase 1 trials and further develop its broader pipeline targeting other cardiometabolic pathways like GIP and amylin. Ambrosia's approach focuses on the structural biology of the target receptor and utilizes an AI-powered molecule design engine to generate differentiated assets, with an emphasis on improved potency, 24-hour target coverage, and combinability compared to first-generation oral GLP-1 drugs.

  • In late December 2025, the FDA approved a pill version of Novo's Wegovy, bringing peptide GLP-1s to the oral arena.
  • Eli Lilly's weight loss pill orforglipron, a small molecule GLP-1 agonist, is currently under FDA review with a decision expected in the coming days.

What they’re saying

“As the field moves beyond first-generation molecules, we see a meaningful opportunity for differentiated small molecule modulators that are designed with combinability in mind.”

— Nick Traggis, CEO, Ambrosia Biosciences

What’s next

Ambrosia plans to initiate a Phase 1 clinical trial for its lead small molecule GLP-1 agonist in the coming months. Structure Therapeutics also intends to launch a late-stage program for its small molecule candidate aleniglipron later this year.

The takeaway

The race is on to develop the next generation of oral GLP-1 agonists, with both large pharmaceutical companies and emerging biotechs pursuing small molecule approaches that could offer advantages over first-generation peptide-based drugs. Ambrosia's AI-powered platform aims to generate differentiated assets that could surpass current oral GLP-1 options.
