FinalSpark

FinalSpark grows biological neural networks in cell cultures and offers them as a computing substrate, arguing that the human brain runs 86 billion neurons on roughly 20 watts while replicating that efficiency in silicon would take megawatts. Its Neuroplatform gives researchers remote, subscription-based access to living human brain organoids with real-time stimulation, recording, and a Python API.

The company positions wetware biocomputing as self-organizing and continuously learning, in contrast to one model per task in traditional AI, and names universities and research groups among its users. It also publishes a recorded neuronal-activity dataset for researchers to use.
