AI startup (stealth) | Co-founder / AI engineers | REMOTE
We’re building an AI system that will disrupt the SaaS market as a whole. The foundation already exists and is running.
The concept itself is not difficult for experts once it becomes public, but the architecture and timing are key. We’re moving extremely fast.
Plan:
- release an open-source core - build a large community around it - scale fast enough to push competitors out
Current state is first friendly test customers onboarding in a few days. This is just 1 week old.
We’re currently reaching out to major AI labs since they could profit a lot from this, but we don’t need them to scale aggressively.
Right now there’s no significant funding yet, but the pace is extremely high and this could gain traction very quickly. We can likely raise ~€250k fairly quickly via public funding in my country, without giving up shares, but first we want to assemble the right people and make a plan together.
Looking for:
- someone with founder experience / VC contacts, or - hardcore AI engineers like me who ship extremely fast
We are currently EU-based, but the company can be set up wherever makes most sense for the business. It's huge fun to work with it.
