Yuma is building a next-generation orchestration platform that deploys autonomous AI agents dedicated to customer support in e-commerce. We already support 150+ paying merchants and help them automate up to 80% of their customer tickets freeing human agents for higher-value conversations.
Founded by Guillaume Luccisano (3rd-time YC founder) at the end of 2022, Yuma is one of the leaders in the AI Support Automation space with 10+ consecutive months of double-digit growth.
We are now a team of 25 passionate and ambitious people based between Paris, Barcelona and Boston and have grown revenue 5x in 2025. We aim to repeat this trajectory in 2026. The scale-up phase is fully underway. 🚀
We remain a small team of 5 engineers, but we are intense and we move very quickly! Fast iteration is key. In the past 2 years since Yuma’s founding, we’ve built a lot, but there is still much more to do! We operate at startup speed and handle everything: product iterations, A/B testing, LLM research, AI Agents pipeline, new feature development, performance optimizations, and more. We are intensely focused on delivering value to our users and on product excellence. That is the only thing that matters.
Our backend is a standard Ruby on Rails API powered by PostgreSQL, Redis, and Sidekiq. Our frontend uses Next.js and React. We already handle a significant load, ingesting and processing millions of support tickets per month and millions of e-commerce data points per day.
We are definitely not a 9-to-5 team, and we are heavily committed to delivering excellence throughout our craft.
You have led and built multiple large Rails applications, and you always strive for excellence. You are pragmatic, making the right trade-offs that favor speed of iteration while maintaining high product quality. You are driven by delivering the best experience and value to your users. You might have a preference for working on backend projects, but you aren't afraid of frontend work. Rails has no secrets for you.
Recent experience playing with LLMs is now mandatory, and you have already adopted AI in your day-to-day tasks. Building with LLMs and managing non-deterministic output is not scary to you.
If you are relentless, deeply caring about delivering value & ownership, and looking to join an early, hard-working team, we want you 👈. We are seeking someone who is looking to embrace a new challenge and commit to it 100%.
Your diploma doesn't matter to us; we only care about your skills, your sense of ownership, and drive.
If you’re still junior, but the description above sounds like the person you aim to become in the next 3 years, don’t be shy: there’s always space for raw talent at Yuma.
Dont' be shy, apply! :)

Yuma is automating customer support by providing an AI Support Agent orchestration platform. Yuma provides autonomous AI agents dedicated to customer service and e-commerce.
We integrate directly with help desk software (Zendesk, Kustomer, Gorgias, etc.) and focus on helping large Shopify brands deal with their high volume of support requests.
Top merchants using Yuma can automate up to 80% of their support tickets fully autonomously.
There are thousands of large Shopify merchants around the world generating $10M+ a year. Most of them have taken over some niches and are great at what they do: selling their products.
But they all have one thing in common: they all hate customer support. It's a burden for them and a huge source of cost, as they receive hundreds of requests per day. Some of them have dozens of support agents on staff, usually offshore, and the overall quality is still often pretty poor while staff turnover remains high.
Those merchants have been promised automation for years but have always been disappointed by the outcome. As customers, we have all had to live through a terrible support automation experience before, so this is no secret, and everyone knows that the current state of the technology is quite bad.
Yuma isn't just another RAG chatbot. Our platform provides autonomous AI agents dedicated to support and ecommerce.
These agents are powered by knowledge, follow processes, and are managed by our in-house AI orchestration technology. This ensures safety, control, and quality at every step.
We believe that to truly automate customer support, we must develop a platform that mimics the actions of a human support agent. That's exactly what we've been doing.
Currently, our top merchants are automating 60% of their support tickets through Yuma. Yuma can fetch information from external services and take actions in other apps as needed to resolve each ticket.
We are laser-focused on building the best AI support agent platform and aim to achieve 80% true automation in the next few months.
Yuma got started by accident. This is my third YC startup after Socialcam (W12) and Triplebyte (S15). I released Yuma as a prototype for fun in mid-December 2022 and was overwhelmed with demo requests. That's when I knew I was onto something and had to turn this into a real company, once again.
