The startup that made me pause my architecture practice

in 2020 I joined a brain sensor startup as a growth intern. it went on Shark Tank India, and then it taught me the more useful lesson.

the short version: I am an architect. I took an internship at a company building a headband that reads your brain, watched it go on national television, and then watched it fail for a reason that had nothing to do with the technology. that second part is why my architecture practice is paused and I do growth instead.

The internship

in 2020 I joined Neuphony. they built EEG neurofeedback headbands, wearables that track brain activity, and I came in as a growth intern doing whatever growth meant that week.

in practice it meant everything unglamorous. I designed the social media in Illustrator and Photoshop, ran the accounts, wrote and shot content, edited the videos, and tried to work out where people who would want a brain sensor actually spend their time. no budget worth mentioning, so it was all organic.

I loved it, which surprised me. architecture is slow. you draw something and find out in three years whether it works. this was the opposite. you post something on tuesday and by wednesday the numbers tell you if you were wrong.

Then it went on Shark Tank India

Neuphony was featured on Shark Tank India in season 2, episode 36. the founders asked for one crore for 2%, at a fifty crore valuation. Aman Gupta and Peyush Bansal offered one crore for 5.4% on air.

the episode aired and the traffic was unlike anything I had seen. a national audience discovers you in twenty two minutes, and every dashboard goes vertical at once.

I should be honest about what happened next, because the internet is full of founders who are not. reporting on the show says the deal did not complete after due diligence. what we got was the exposure, and the exposure was real.

The lesson was in what came after

here is the part I think about most.

the spike faded, and the product still did not sell the way anyone hoped. not because it was bad. the technology was genuinely good. the problem was that a detailed brain sensing headband is a product for a very small group of people, and most of them were senior enough to buy one out of curiosity rather than need.

the product was ahead of its time. that phrase gets used as a compliment and it is not one. being early means being right about the future and wrong about this quarter, and companies do not run on being eventually right.

Neuphony is deadpooled now. the founders took the same technology, compressed it into a pair of headphones, and started again as Sychedelic, which raised a $3.5 million seed round. same science, a form factor people already own and already understand.

that is the whole lesson in one move. the technology did not need fixing. the way it reached people did.

Why I do this now

I paused my architecture practice because of that year. paused, not abandoned. the training still runs everything I do, and I expect to build again. but I watched a good product lose to a distribution problem, realised distribution was the more interesting problem, and it has held my attention ever since.

everything I have done since is that same idea. I scaled ZuAI from 10,000 to 2 million users at a $0.02 blended CAC, and the case study is mostly about channels rather than product. the product was already good. it usually is.

if your product is ready and your distribution is not, that is the position I know best, because I have watched what happens when nobody solves it in time.
