Blue

Blue is a small USB-C plug-in for iPhone. It lets a voice assistant tap and type in any app on the phone, so you can get something done without picking the phone up.

People who find a touchscreen hard to use, and anyone who wants to use their phone by voice.

The work

I am a co-founder and I run hardware: the enclosure, the parts inside it, the factory that makes them and the packaging.

The first 100 units went from a whiteboard sketch to finished, boxed units in 55 days, in time for Y Combinator Demo Day. The parts and the work behind those units came from four places: the Bay Area, Argentina, Taiwan and Shenzhen.

One problem: factories in Shenzhen close for weeks over Chinese New Year. A part that is not ordered before they close cannot be made until they reopen, at any price. We had planned the schedule around our design reviews and had not checked the factory’s holidays. We changed the plan to work back from the factory’s last open day, and ordered the slowest parts weeks early.

Bud, close up.
