I just publicly demoed the wearable I spent 6 years building. Here’s what closing the seed and getting to a working product actually looked like.

Today I sat down and demoed the finished production version of the wearable I've been building for the last 6 years. The pods snap into the tape. The app connects. The session runs. After 8 prototypes and a manufacturing wall that almost killed the project, the thing actually works.

I wanted to share what the last stretch of this journey looked like, because the months between closing our seed round and getting to a public demo have been the most operationally intense of the entire build.

Closing the seed changed everything

We closed our Series Seed earlier this year. The difference between "looking for capital" and "deploying capital" is night and day. Every conversation, every supplier negotiation, every hire is different when you're not also pitching simultaneously.

Lesson: Closing your round is not the finish line. It's the starting line. The work that happens after the wire hits is what determines if the round was worth raising.

The demo is the milestone, not the close

Investors don't care that you raised. Potential customers don't care that you raised. The only thing anyone outside your cap table cares about is whether the product works. We spent the months after closing focused entirely on going from a working demo to a production ready product. Everything else was secondary.

Lesson: After a fundraise, founders have a tendency to celebrate. Resist it. Pour every dollar and every hour into proving the thing you raised money to build.

The freelancer to real team transition

Earlier in the build I made the mistake of hiring cheap. A freelance EE took thousands of dollars and months of time and delivered nothing usable. We finally brought everything internal and I worked with the team until we were proud of the final product. We delivered in months what the freelancers couldn't deliver in years.

Lesson: The cheapest engineer is never the cheapest option. This is the most expensive lesson I've learned in 6 years.

The materials problem nobody warned me about

The hardest part of building this wasn't the electronics or the firmware. It was figuring out how to get everything to work together. Every time we solved one constraint we broke another. 4 years of development time disappeared into solving that one problem.

Lesson: If your hardware product depends on materials science, hire the materials expert before you hire the EE. The constraint will dictate everything else.

The 84 hour decision

There was a moment earlier this year where I had to decide if I was going to walk away. The bill of materials wasn't working. The math didn't math. Every previous engineering decision had to be re-evaluated. I locked myself in a room and didn't come out for 84 hours. I came out with a path forward.

Lesson: The moments where you almost quit are usually right before the thing that changes everything. The discomfort of pushing through is real. So is the regret of walking away the day before the breakthrough.

Where we are now

Series Seed closed. Production demo is live. Working through regulatory clearance. Targeting commercial launch later this year. Every dollar is being spent on getting to market.
