Resonant Technologies Group (RTG) is a San Francisco Bay Area company that creates and accelerates science and technology ventures in health, energy, agriculture, and the environment. Founded in 2019 and based in Sausalito, California, it works with inventors, scientists, and engineers to develop, commercialize, and license their technologies through a portfolio of operating companies.
RTG builds its companies on what it calls resonance physics, a model of energy and frequency that the company says reflects nearly 20 years of research by its founders and collaborators; the framework is RTG's own rather than an established field of physics. Its model resembles a venture studio: it develops technologies and spins them into standalone operating companies rather than investing passively. As of 2026, its portfolio includes Sonaphi (health diagnostics and neurofeedback), SourceWave (frequency-based health products), Divina Biotech (immunotherapy serums), UpTerra (frequency-enabled agriculture), Field Futures (metal and mineral extraction), Form Audio (audio hardware), and Manna Vitality (supplements).
