Robust AWS infrastructure

Describe their project management. Did they deliver items on time? How did they respond to your needs?

We have a joint slack channel with regular communication and have a seemless relationship. It is wonderful working with them, the ML challenges we face and some of the engineering activities are novel and as such, our timelines have required flexibility. Overall these guys are terrific, it's a joy working with them

They have the ability to help solve problems and the resiliency to continue attacking challenges with no obvious solutions.

More coherent project management such as JIRA tickets would put many minds at ease. The work gets done but the larger a project the more important it is to make sure everyone is accountable and that nothing slips through the cracks.

Our Story

Sigma Square is built on a simple belief: the best technology comes from people who care about the problem, not just the code. Our engineers, data specialists, product thinkers, and cloud practitioners work as one team to turn complex AI and data ideas into useful products. We value curiosity, honest communication, and ownership. Our mission is to build solutions clients can understand, trust, and continue using—and leave their teams stronger through clear collaboration and handover.

What Sets Us Apart

AI You Can Verify

AI should do more than impress in a demo. We build working applications with results that can be tested and understood, helping clients move forward with confidence instead of being left with a black box.

Built Beyond the Model

An AI model is only one part of the product. We connect AI and data engineering with product UX, integrations, and cloud deployment, giving clients a complete working solution instead of a collection of disconnected parts.

A Team That Stays Close to the Work

Our engineers work across AI, data, backend, frontend, cloud, and QA as one connected team. Leads stay close to reviews and delivery, so clients spend less time coordinating specialists and more time moving the product forward.

Commonly Asked Questions

We are a good fit for B2B software products, data platforms, workflow tools, cloud applications, and product modernization. We prefer projects where engineering, UX, integrations, and deployment must come together around a clear outcome.

We agree on the scope, priorities, responsibilities, and working rhythm at kickoff. Delivery then moves through focused cycles with regular updates, demos, code reviews, QA, and feedback. We can work within your existing tools or establish a shared workflow.

We work as a connected product team rather than a group of isolated specialists. Our engineers collaborate across backend, frontend, data, cloud, and QA, while delivery leads stay close to priorities, reviews, feedback, and escalations.

Yes—when the use case, data, ownership, security requirements, and acceptance criteria are clear. We can assess the pilot, strengthen its architecture and evaluation, connect it to real systems, deploy it, and prepare your team to operate it.

Our work includes RAG and knowledge assistants, AI-generated reports, data copilots, document workflows, intelligent analytics, and AI learning products. We also handle the supporting data, product UX, integrations, evaluation, and deployment.
