Come and build
The Agent of Record for CX
Join a team of builders defining a category for consumer brands.
Creators and doers
Consumer brands run ten or more disconnected tools to manage their customers. We collapse that stack into one agent. Support first, then shopping, then social, then everywhere else a customer turns up.
Hundreds of brands already run real customer volume on Siena in production. What you build here reaches their customers the same week. The system is live, people depend on it, and it is nowhere near finished.
We are small, distributed and fast on purpose, and that only holds while everyone here owns a real outcome. If you want a defined lane and a roadmap handed to you, we will frustrate you. If you would rather take a problem nobody has solved yet and carry it all the way to the end, we should talk.

Why people build here
Lou
Agent Engineer
Hamilton, New Zealand
I’ve always been curious about the technicalities of how Siena functions. That curiosity, plus helping our customers unblock something, was what brought me to the CX team.
Patricio
Forward Deployed PM
Cordoba, Argentina
AI-first at Siena is something you see every day. It shows up in how non-technical teams instinctively reach for AI reasoning before anything else.
Promise
Forward Deployed Engineer
Nairobi, Kenya
Siena gave me the opportunity to be a pioneer, an early member of something big. Nowhere else put me on that edge and trusted me to deliver.
Carla
Deployment Manager
Buenos Aires, Argentina
What stands out is how much thought goes into everything, from the product to our customers, all within a genuinely kind and collaborative culture.
Truly remote global team
Work from wherever you do your best work. Every timezone counts the same.
AI-fluent by default
Your own stack of agents, on accounts we pay for, plus a quarterly budget for what’s next.
Freedom to act
Everyone has a voice and impact across the whole company.
From first principles
There’s no playbook for what we’re building, so we reason it out from scratch.
Extreme ownership
You own the outcome, not the task. If it’s yours, you carry it all the way to the end.
We move fast
What you build reaches customers the same week, not the same quarter.
