Sumgrey was born inside an operation. Not outside it.
We've spent over 25 years managing contact centers. Sumgrey is what we built when we decided AI had to genuinely enter that operation.
"No llegamos al sector con una solución buscando dónde aplicarla. Llegamos desde dentro."
AI alone doesn't fix an operation.
What we usually find isn't a lack of tools, but too many disconnected pieces. An isolated chatbot or a voice agent without context can create more noise than value if it isn't connected to processes, data and people.
That's why we combine process design, technical implementation and in-house product development when a dedicated layer is needed to supervise or decide better.
We know what happens when a 200-agent operation breaks at 3pm on a Monday.
We didn't come to the contact center sector with an AI solution looking for somewhere to apply it. We came from inside — with over 25 years managing real operations, with SLAs to meet, legacy systems to integrate and teams under constant pressure.
That changes how we build. We know what fails first, which promises go unmet and what needs to work from day one. Sumgrey exists because we couldn't find what we needed — so we decided to build it.
Our own product. Direct implementation. No middlemen.
caller.ee and summy.pro are ours. We develop them, maintain them and deploy them ourselves. You don't depend on a third-party license or a partner who doesn't know your operation.
When we step into a project, it's someone who understands the operation — not a consultant studying it for the first time. That reduces ramp-up time, misunderstandings and surprises in production.
The solution has to be useful in the team's day-to-day, not just convincing in a demo.
Experience operating contact centers and BPOs
From the first session to production
Of conversations analyzed, not samples
In on-premise deployments
Companies that handle conversations at scale and need AI to actually work.
Contact centers, BPOs, telecommunications, financial services. Mid-size and large companies where conversation volume is high and the margin for error is low.
We don't work with everyone. Before proposing anything, we take the time to understand whether we're a fit. If we're not, we'll tell you.
Support, escalation, supervision and quality where consistency matters as much as speed.
Operations with high contact volume, multiple systems and a need for traceability in every interaction.
Complex processes where calls, chats and internal management are part of the daily work.
Teams where privacy, traceability and compliance are not optional.
