AI agents
Build agents that can understand tasks, use tools, retrieve information and take actions across business systems.
AI Development Company
UK
WeUno is a UK AI development company building production AI agents, RAG systems and intelligent software. Our engineering team developed Vellum Mortgage’s underwriting AI using LangChain, Pinecone and AWS to deliver source-grounded answers across 200+ lending and policy documents. We take AI from architecture and integration through deployment, evaluation and ongoing improvement.
UK AI Development Company for Production AI Software
The value of AI comes from how well it fits into the product, workflow and data around it.
WeUno Technologies is a UK AI development company that helps businesses identify where AI can create meaningful value, then designs and engineers custom AI systems that work reliably in production. Our work includes retrieval-augmented generation (RAG) development, AI agents, generative AI, and AI integrations into existing software. Our team covers the product, software engineering and AI layer from prototype through production. For Vellum Mortgage, we engineered a RAG-based underwriting assistant drawing on more than 200 investor, agency and internal documents, with LangChain agent orchestration, Pinecone retrieval and AWS infrastructure.

What we build
RAG systems
Connect large language models to your own documents, knowledge bases and enterprise data.
AI-powered search
Build natural-language search experiences across complex datasets and knowledge sources.
Generative AI applications
Create products that generate, analyse, summarise and transform information using modern language models.
Document intelligence
Extract, classify, analyse and reason across large volumes of structured and unstructured documents.
AI copilots
Create intelligent assistants embedded inside existing products and workflows.
AI automation
Use AI to support repetitive, knowledge-heavy or multi-step business processes.
Custom AI products
Build complete AI-native products from product strategy through engineering and launch.
Model and platform flexibility
AI technology is changing quickly. Where practical, we avoid unnecessary dependence on one model or provider.
Our teams can work across OpenAI, Azure OpenAI, Anthropic, Google models, open-source models, vector databases, cloud AI services and custom model APIs.
What goes into every AI system we build
From prototype to production
We build in the practices that separate a working demo from a system your business can rely on: reliable outputs, rigorous evaluation, safety guardrails, strong security and continuous monitoring. Cost, performance and scalability are considered from day one, alongside human oversight and integration with the systems you already run.
AI that works with your data
Your AI is only as useful as the data behind it. We connect systems to your internal documents, databases, CRMs, APIs and knowledge bases, respecting user permissions and working with your existing cloud storage, business systems and SaaS platforms.
AI engineering capabilities
Our engineers cover the full AI stack: prompt engineering, retrieval pipelines, embeddings and vector search, agent orchestration and tool calling, alongside the API integration, data pipelines, backend engineering and cloud infrastructure needed to run it in production.
Security and governance
Every system we build considers authentication, roles and permissions, and data isolation from the start. We plan for prompt injection risk and sensitive information handling, with audit trails, logging and human approval points built in where they matter.

Why WeUno
AI plus software engineering
We build both the AI layer and the systems it needs to run in, from backend and infrastructure to the product itself.
Built for production
We plan for evaluation, monitoring, cost control and scalability from day one, not as an afterthought once something breaks.
Model and platform flexibility
AI technology moves fast. We avoid unnecessary dependence on one model or provider, working across OpenAI, Azure OpenAI, Anthropic, Google models and open-source alternatives.
Proven on complex AI systems
We engineered Vellum Mortgage's mortgage-underwriting AI with retrieval-augmented generation, specialised agents and sourced answers across 200+ investor, agency and internal documents. The platform uses LangChain orchestration and Pinecone retrieval, with role-based access controls and AWS infrastructure. See the Vellum Mortgage case study for the architecture and implementation. Independent client evidence: in a verified Clutch review, SuperPowerMe's founder confirmed that WeUno built the frontend and backend of its AI copilot MVP and delivered on time and within budget.
