Humm sells a disposable forehead patch that delivers small electrical pulses to entrain brainwaves and enhance working memory capacity. The company launched its first product in August and charges about $5 per patch; the patch is used in roughly 15–30 minute sessions and is recommended no more than twice daily. Humm ran a 40‑participant study with UC Berkeley showing roughly 20% improvement on certain memory tests versus placebo, and cites broader academic work (Boston University/Nature Neuroscience) supporting mild electrical stimulation for memory. The startup graduated from Berkeley SkyDeck and has run tests with hundreds of early access users who reported faster language learning and improved recall. Humm says the $2.6M seed will be used to scale production and prepare for commercial rollout, and it has closed early access after a reported Air Force trial order for 10,000 devices; the company expects commercial availability by Q3 next year.
