Independent study and practice / Solo-founder product exploration
Neurofeedback and biofeedback: a hardware boundary
I spent 2021–2025 studying and practicing neurofeedback and biofeedback. In 2025, I tried to develop a mobile product from that experience as a solo founder.

From an interest in people to a product question
This work grew out of my longer engagement with psychology, psychophysiology and self-regulation. I wanted to explore what a mobile product could make possible, rather than stop at studying methods or using existing tools.
The product question required understanding both the software and the quality of the measurements on which feedback would depend.
The constraint was below the software
The devices I evaluated below roughly $3,000 did not provide the signal quality I needed for the intended product. I paused that product attempt instead of treating the limitation as something that more application development would solve.
This is a conclusion about my intended use, the equipment I evaluated and the requirements I set at the time. It is not a claim that every device below that price is unusable for every neurofeedback or biofeedback task.
What the attempt taught me
A useful product decision can be to stop when a foundational dependency does not meet the requirements. An interface that appears to work does not settle whether the underlying measurement is good enough for its purpose.
This was an independent product exploration, not a clinically validated treatment or an established commercial business. Its value in my engineering history is the work of investigating a domain, testing a product constraint and changing direction when the constraint mattered more than the software.
