Build production AI that customers own.
Plexe is an applied AI lab (YC X25) that builds, deploys and embeds real production AI systems inside customers' products - live in weeks, running on their servers, theirs to keep. We're a small team shipping hard things fast.
Forward-deployed. Outcome-owned.
We don't hand off decks. We build alongside customers and stay until it runs in production.
Ship inside the customer's stack.
We embed with the teams we build for, deploy into their environment, and stay until it works in production - not a slide, not a pilot that stalls.
We're measured on what goes live.
Every engineer here owns real production systems A/B validated against whatever runs today. The bar is impact in weeks, not tickets closed.
Backed by YC, operators from Microsoft & Shopify.
You'll work directly with the founders on hard problems across ML, agents and infrastructure, with the autonomy that comes with an early team.
Builders who see it through to production.
- Engineers who ship production systems, not prototypes
- ML / applied AI depth - models, agents, RAG, evals
- Comfort going forward-deployed with enterprise customers
- Ownership mindset: you see problems through to production
- Bias for speed without cutting corners on reliability
We're hiring.
