Companies that chose to build with us
Most businesses do not have an AI problem. They have a delivery problem.
Perimattic is the AI development company that closes that gap. We take your use case from whiteboard to working system, building custom AI solutions on the technologies that matter: large language models, agentic AI, computer vision, and predictive analytics. We do not run pilots that go nowhere. We build enterprise AI systems designed for production from day one.
What we build
Six AI and technology capabilities. One team that delivers all of them.
AI agent development
We build autonomous AI agents that handle multi-step workflows without human intervention. From customer support agents to internal operations systems, our agentic AI solutions use LangChain, LlamaIndex, and custom LLM orchestration to run at production scale.

We develop generative AI applications on GPT-4, Claude, Gemini, and Llama. Our builds include RAG-powered knowledge systems, content generation pipelines, and multi-modal AI applications that connect language, vision, and structured data.

Before we write a line of code, we map your AI opportunity against your data, infrastructure, and team. Our AI consulting service produces a prioritized roadmap with defined use cases, model selection, build vs. buy recommendations, and ROI projections.
Start with AI consultingMachine learning development
We build and deploy machine learning models for predictive analytics, classification, anomaly detection, and recommendation systems. Our ML engineering practice covers the full lifecycle: data engineering, model training, MLOps, and ongoing monitoring in production.

We help enterprises replace manual processes with AI-powered systems. From legacy modernization to cloud-native AI infrastructure on AWS, our digital transformation work focuses on measurable operational outcomes, not technology for its own sake.

We implement and extend ERPNext with custom AI modules that connect your ERP data to machine learning models for demand forecasting, inventory optimization, and process automation. AI integration services cover CRMs, ERPs, and custom enterprise platforms.

“Perimattic delivered a production-ready AI system that our team actually uses every day. They understood the problem before writing a single line of code, and the outcome exceeded our expectations.”
James R.
CTO, US FinTech Company
“The team is transparent, technically sharp, and genuinely invested in outcomes. Every sprint ended with a working demo — no status reports, just results.”
Sarah M.
VP of Operations, UK Healthcare Organisation
“We evaluated three AI development companies. Perimattic was the only one that asked the hard questions upfront and built exactly what we needed — on time and on budget.”
David L.
Head of Digital, Global Logistics Operator
The industries where our AI ships
We have built and deployed AI systems in six verticals. Here is what that looks like in practice.
How we turn your AI use case into a working system
A 5-stage process built to eliminate the delays, misaligned expectations, and abandoned pilots that kill most enterprise AI projects.
Discovery and AI scoping
We audit your data, existing systems, and business goals. We define the AI use case, success metrics, and technical constraints before a single model is trained. Output: a scoping document with a defined build path and a go / no-go decision point.
Architecture and model selection
We choose the right model architecture for your problem: fine-tuned LLM, RAG system, supervised machine learning model, or autonomous AI agent. We document the build plan and get sign-off before building anything.
Development and iteration
Agile sprints with weekly output. You see working builds, not status reports. We iterate based on real feedback, not assumptions. Every sprint closes with a demo.
Integration and testing
We connect the AI system to your existing infrastructure: CRMs, ERPs, cloud platforms, and APIs. We run evaluation frameworks specific to AI output quality, hallucination rate, and latency, not just functional testing.
Deployment and ongoing support
We deploy to your cloud environment, configure MLOps monitoring, and provide post-launch support. AI models drift over time. We build maintenance and retraining into the engagement from the start, not as an afterthought.

Why businesses in the US and UK choose us as their AI development company
We build for production, not for demos
80% of enterprise AI projects never reach production. Perimattic's delivery framework is designed to get your system live, with governance, monitoring, and scale built in from day one. We measure our success by whether the AI runs in your environment, not by whether the prototype impressed a boardroom.
Full-stack AI capability in a single team
Data engineering, model development, MLOps, frontend, and cloud infrastructure. One team. No subcontractors. No coordination overhead between vendors. When you work with Perimattic, every layer of the system is owned by the same group of engineers.
Transparent delivery with commercial-grade tools
Every project runs on Jira and Confluence with 100% visibility into sprint progress, blockers, and decisions. You always know where your build stands. No updates that say 'good progress.' Only updates with evidence.
Deep vertical experience across six industries
Banking, financial services, healthcare, manufacturing, logistics, and travel. When we build AI for your industry, we bring domain knowledge to the model design. The difference between a generic AI system and one that actually performs in your context is the domain understanding built into its architecture.
