This is a multi-kW DC system problem (battery pack, resistive heater, contactor, safety logic). The constraint is reaching sauna temps without relying on a 240V wall connection.
We currently generate ~$5k MRR renting saunas in the SF Bay (sfsaunarental.com). We've validated pain-point and demand.
If there’s mutual interest and the prototype goes well, this could extend into deeper collaboration or a more dedicated role.

We're Zach and Carl. Previously we worked on a small team at a startup writing software. That project involved impressive military hardware and guys who could literally snap us like twigs; our contribution was rock-solid code for use on distributed systems. We decided we'd try to keep rolling together and post here as a pair. Think of us as a no-money-down aqui-hire. (we're also available individually!)
Location: San Francisco
