About Nexa AI.
Why Nexa exists
The shift from software-as-a-service to agent-as-a-service is real and it's happening fast. The gap isn't the technology — it's the distance between “we should use AI” and “we shipped AI that actually does something.”
UK SMBs have the same problems that large enterprises are automating away — invoice processing, customer support, report building, data entry — but without the in-house engineering teams to tackle them. Nexa exists to close that gap: scope quickly, build in weeks, hand it over.
How we work
Weeks, not months.
Most projects ship an initial working version in 2–4 weeks. We scope tightly, build the core, then iterate — rather than spending three months in planning.
You own the code.
No lock-in. The code is yours, deployed on your infrastructure (Vercel, Firebase) where it makes sense. We hand over the repo on day one.
No filler, no retainers you don't need.
If the right answer is a £500 automation rather than a £12k agent, that's what we'll say. The audit is honest about this.
We tell you when AI is the wrong tool.
Some problems are better solved by a better spreadsheet or a clearer process. We'd rather say that upfront than build something you won't use.
Stack
We build on Next.js 16 with Tailwind v4, deployed to Vercel. AI features run through the Vercel AI SDK v6 and Vercel AI Gateway — so we can route between Claude (Sonnet, Haiku, Opus) by task type and cost. Persistence and auth on Firebase Admin, transactional email via Resend. Nothing exotic; everything battle-tested by teams larger than ours.
We publish stack decisions openly because clients should know what they're inheriting.
The founder
Tristan Glaves, based in the UK. Background in software engineering and product. Nexa launched in 2026 — the tools are mature enough, the models are capable enough, and the pricing has come down enough to build things that would have taken a team of five two years ago.
