International collaboration is key when it comes to scientific developments, and brain-computer interface (BCI) companies are quickly moving in that direction. INBRAIN Neuroelectronics, a leading Spanish-based company developing BCI therapies, has partnered with Mayo Clinic in Rochester, Minnesota, USA, to accelerate the advancement of its graphene-based brain technologies. Last year, patients from all 50 U.S. states and 135 countries received care at Mayo Clinic. To date, the company has raised $124 million from investors, including Mayo Clinic, European and Spanish government initiatives, and several venture capital firms. “These programs have provided critical early-stage funding and infrastructure that allowed us to scale our graphene-based BCI platform and advance toward clinical validation,” Aguilar says.
