Technologies
Platform choice should follow the business problem
Tech agnostic, outcome led.
Most platform decisions get made before the problem is understood. We work the other way: define the outcome, then pick the tools that get you there with the least cost and risk.

Common questions about the platforms we use
What does CG TECH mean by technologies?
These are the platforms we build on: Microsoft, OpenAI, Anthropic, Perplexity, open source, and the specialist tools around them. Each page explains what a product does, where it fits, and where it does not.
Are you tied to one technology vendor?
No. We are a Microsoft Solutions Partner with deep Microsoft skills, and we are genuinely technology-agnostic across OpenAI, Anthropic, Perplexity and open-source. We pick what fits the work, your budget and your data rules.
How do you decide which platform to use?
We weigh four things: the quality the task needs, the cost to run it at scale, where the data is allowed to live, and how it fits what you already have. The answer is often a mix, joined up safely.
Can you run AI on our own infrastructure?
Yes. When data residency or cost calls for it, we run open models on infrastructure you control rather than sending data to a public service.
Where should we start if we are new to all this?
With a problem, not a product. Pick one task that is slow, repetitive or error prone, and we will tell you which of these tools fits it and what it would take. Starting from the product is how businesses end up with licences nobody uses.
What size organisation do you work with?
Our sweet spot is 50 to 500 seats. Large enough for this work to be worth doing properly, small enough to see a result within a quarter.
Do we need every tool listed here?
No. Most businesses use a small number of them well. These pages are here so you can see what each one does before deciding, not as a shopping list.
How do you keep up as these products change?
We use them ourselves, in our own business, before we recommend them. When something changes materially we update these pages, and we tell the clients it affects.
