Trusted by ambitious teams to design & deploy custom AI agents.
What we doAn AI agent development company for custom, connected agentic systems
&above is an AI agent development company based in Southwark, London. We design and build custom AI agents - agentic systems that connect to your tools, data and business logic so they can take action, not just generate a response.
Most off-the-shelf AI assistants stop at answering questions. We build custom AI solutions that go further: agents that read from and write to your CRM, your internal APIs, your knowledge base and your workflows, with the permissions and guardrails an enterprise needs. That means real AI integration services work alongside the agent build itself - the agent is only as useful as the systems it's connected to.
We work with scale-ups and global enterprises alike as an enterprise AI solutions partner - small senior squads, startup pace, enterprise-grade delivery, guardrails and observability built in from day one. Looking for automation or a broader AI software build too? See our AI agency services. Building a new product from scratch? See our digital product agency services.
Custom agent development, integrated end to end
What AI agent development delivers - agents designed around your business logic, connected to your real systems, and run with enterprise-grade guardrails.
Agentic AI design
Agents built around your logic.
We design custom AI agents around your specific business logic and decision-making - not a generic chatbot wrapper. Every agent is scoped to the tasks it should actually own.
We defined & piloted a creative intelligence agent with Sage to drive ads ROI.
AI integration services
Connected to your real systems.
Custom AI solutions connected to your CRM, internal APIs, data warehouse and existing tools - so agents can retrieve real context and act, with proper authentication and access control.
We uncovered sales opportunities for 5,000 Googlers with an agentic sales system.
Enterprise AI solutions
Guardrails, from day one.
Permissions, business-logic guardrails, and observability built into every agent system we ship - so agentic AI is safe to run at enterprise scale, not just in a demo.
We built an AI-native creative studio that took Tesco's retail ads from four-week approvals to days.

AI agent development FAQs
Straight answers for teams evaluating an AI agent development company.
- What is AI agent development?
- AI agent development is the process of designing, building and deploying AI agents - systems that can reason about a task and take action, not just generate a response. That includes defining the agent's business logic, connecting it to real tools and data, and adding the permissions and guardrails needed to run it safely.
- What is the difference between an AI agent and a chatbot?
- A chatbot answers questions. An AI agent acts - it can read from and write to your systems, chain together multiple steps, and complete a task on your behalf within defined guardrails. Most of what we build sits closer to the agent end: connected to real tools, not just a conversation window.
- Do you offer custom AI solutions or off-the-shelf agents?
- Custom. Off-the-shelf AI assistants are built for the general case; we design agents around your specific business logic, data, and workflows, so the agent actually fits how your team works rather than the other way round.
- What does AI integration services work involve?
- Connecting an agent to your existing systems - CRM, internal APIs, data warehouse, knowledge base, and tools like Slack - with proper authentication, permissions, and access control, so the agent has real context to act on rather than working from a static prompt.
- Is agentic AI safe to run at enterprise scale?
- It can be, with the right guardrails: scoped permissions, business-logic constraints, human-in-the-loop checkpoints where needed, and observability so you can see what an agent did and why. We build these in from day one rather than bolting them on after a proof of concept.
- How is &above different from other AI agent development companies?
- We combine agent design, systems integration, and enterprise-grade guardrails in one embedded squad, backed by delivery experience spanning scale-ups and enterprises: Google, Tesco, Sage, Revolut, and YourAvatar. Small senior teams, startup pace, production quality.
- Do you work with scale-ups as well as enterprises?
- Yes. We work with ambitious scale-ups and global enterprises - from YourAvatar and Upstix to Google and Tesco. The engagement model adapts to your stage: discovery sprints and proofs of concept for early bets, embedded squads for full agent builds and integration.
- Where is your AI agent development company based?
- Our HQ is in Southwark, London - The Binary, 27 Copperfield Street, SE1 0EN. We work with clients across the UK and internationally, from scale-ups to global enterprises.
