Customer Success Manager - Enterprise

2501 builds autonomous AI agents that operate directly in the shell to complete real production tasks - not just synthetic evals. We treat LLMs as pluggable brains, mixing open‑source and flagship models to get the best result. By fusing their output with observability data we surface root causes fast and automate the dull parts of incident response for corporate engineering teams who can’t afford downtime.

We’re a tight‑knit team who ship fast, learn constantly, and elevate each other every day.

Why 2501 ?

We use AI to solve real problems in the underlying layers of every IT stack. We build what is the future of IT, ensuring every brick of our clients’ infrastructure is up and running.

We discovered an amazing opportunity to make IT more reliable and modern and we’re building the best way to make it a reality. Our customers and investors and backing this with strong commitment and foresee in our mission the future of IT.

We’re backed by three leading European VC funds, giving us the resources to aim high and take risks. And we’re just getting started!

Not for you if

• You want a purely reactive support-desk role.

Why you’ll enjoy working here

• Competitive pay & meaningful equity – you own a piece of what you build.
• Small global team, big impact – your work ships to users the same day. We're still small enough that every new hire changes the company; this isn't a seat maintaining a corner of a big machine.
