AI agents · Websites · Apps · Platforms
Custom software, built in weeks - and you own every line.
A UK product studio building AI agents, websites, apps and platforms - production-grade, quoted up front, and yours to keep.
From signed brief to live software.
Every build made to your exact request.
Of the code, repo and data - yours.
Lock-in, retainers, mystery invoices.
The problem
You've had at least one of these conversations.
"The quote was £60,000."
Enterprise vendors price for enterprises. You're not one.
"The agency vanished after launch."
Their repo, their hosting, a new invoice for every change. That's not a partnership.
"So we're still on spreadsheets."
Fourteen tabs, one person who understands them. Fine - until they leave.
We started DevAgent Solutions because the cost of building software collapsed - and almost nobody passed the saving on.
Who this is for
Real people, real deadlines.
How we work
Small, senior, and fast - on purpose.
Most agencies quietly use AI and bill the old hourly rates. We do the opposite: senior engineers direct every build, AI amplifies the pace, and the judgment stays human. Four weeks instead of four months - at a fraction of the quote.
What we build
AI agents are our specialism.
And we build the websites, apps and platforms around them just as properly - scoped to your needs, live in weeks, and yours to keep.
AI Agents & Assistants
Assistants, chatbots and automations that handle the repetitive work - grounded in your data, with guardrails and a human in the loop. This is what we do best.
Websites
Sites that earn trust in five seconds and rank on Google - from a sharp one-pager to a full CMS or online shop.
Apps
Fast, good-looking apps your customers or team actually enjoy using - with the plumbing (auth, payments, data) done right.
Platforms
The system your whole operation runs on: dashboards, client and member portals, case management, live reporting.

Bespoke by default
Every build is made to your request.
No templates, no off-the-shelf products. You describe the problem; we design and build the thing that solves it. A few we're often asked for:

Proof
Not sure we can build it? You're looking at proof.
The hero, the motion, every section on this page - we designed and built it. The fastest way to show what we can do is to build something worth looking at, right in front of you. Your project gets the same care.
Detailed, honest case studies are on the way. See where that stands →
This hero, hand-built
A real-time 3D video, gated for speed - not a stock template.
Sub-second, no framework
Hand-written vanilla code, tuned to load instantly.
Every section, from scratch
Designed, built and accessibility-checked to WCAG 2.2 AA.
Our promises, in writing
One clear quote, up front.
We scope your project, then agree the price before we build. No surprise invoices.
Full ownership from day one.
Your GitHub org, your hosting, your data. If we vanished tomorrow, you'd lose nothing.
Plain-English everything.
Contracts, docs and handover a non-technical client can read.
No lock-in maintenance.
Optional support plans exist. Ransoms don't.
Straight answers
The questions you're actually asking.
How can you be so much cheaper than the agency quotes?
A small, senior team using modern tooling - including AI - instead of a pyramid of juniors billing hours. No account managers, no sales team, no padding. The saving is structural, and we pass it on rather than pocket it.
Do I really own everything?
Yes. The code lives in your GitHub, the hosting in your accounts, the data in your database - from day one. Full ownership and a complete handover are included on every project, never an add-on. If we vanished tomorrow, you'd lose nothing.
Is this just AI-generated code?
No. Senior engineers own the architecture, the security, and every decision that matters. AI speeds the work up; the judgment stays human. Anything touching money, people or records is reviewed by a person before it ships.
What if I need changes after launch?
You can - or any developer you hire can - because we hand over clean, documented, standard code with no lock-in. Optional monthly support is there if you'd rather keep us on call, but it's a choice, never a ransom.
How is the price really "fixed"?
After a free 20-minute scope we give you one number, and that number is what you pay. If you later ask for more scope, we price it in writing before we build it - so there's never a surprise invoice.
What if I'm not sure exactly what I need?
That's normal, and it's what the scope call is for. Tell us the problem in plain English and we'll tell you honestly what's worth building, what isn't, and what it would cost. Start a brief →
Tell us what you want built.
Twenty minutes, no pitch deck. Describe the product or workflow you have in mind - we'll tell you honestly whether we're the right people, exactly what it'll cost, and how fast it'll be live.
