Ask HN: Who is looking for a co-founder? (December 2021)

Building on the "Who is Hiring?" threads, here comes a monthly thread for folks who are in search of a co-founder. Let people know what you are building and what you are looking for in a co-founder. Please state the location and include REMOTE if you are open to building a company remotely. When remote work is not an option, include ONSITE. Please only post if you are the founder (or one of the co-founders) of the startup. No recruiting firms, venture builders, or job boards. Only one post per company (how many co-founders can one look for anyway). Please explain on a high level what your company does. Commenters: please don't reply to these posts telling people why their idea won't work. It's off-topic here. Readers: please only email if you are personally interested in committing yourself to a co-founder role. No "CTO for hire" companies! P.S. This is simply following on from threads posted by "whoisbuilding", as there hasn't been a new one since August.
