Our Approach

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 Do

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.

Generative AI development

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.

AI consulting and strategy

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 consulting

Machine 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.

Digital transformation with AI

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.

How We Work

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.

01

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.

02

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.

03

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.

04

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.

05

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 Perimattic

Why businesses in the US and UK choose us as their AI development company

01

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.

02

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.

03

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.

04

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.

Frequently Asked Questions

AI development, answered

Straight answers to the questions we hear most from US and UK enterprise buyers.

What is an AI development company?

An AI development company designs, builds, and deploys custom artificial intelligence systems for business use. Unlike an AI consultancy that only advises, an AI development company owns the full engineering lifecycle: data pipelines, model selection, integration, MLOps, and production support. Perimattic is an AI development company serving enterprises across the United States and United Kingdom.

How much does custom AI development cost in the US and UK?

Custom AI development projects typically range from $25,000 for a scoped proof of concept to $250,000+ for a full production system. Perimattic engages at $25–$49 per hour, and most enterprise AI builds land between $50,000 and $150,000 depending on data readiness, model complexity, and integration surface. We provide fixed-scope estimates after a discovery call.

How long does a typical AI build take?

A production-ready AI system usually takes 8 to 20 weeks end to end. A scoped proof of concept can ship in 2 to 4 weeks. Timelines depend on data availability, integration complexity, and whether the model is built on a hosted foundation model (GPT-4, Claude, Gemini) or custom-trained. Perimattic runs weekly sprints with working demos at each milestone.

What's the difference between AI consulting and AI development?

AI consulting produces a strategy, roadmap, and use-case prioritization — no code. AI development is the engineering work that turns that roadmap into a running system: data engineering, model training, application code, deployment, and monitoring. Perimattic offers both, but our core practice is AI development — we ship systems, not slide decks.

Which industries does Perimattic serve?

Perimattic delivers AI systems across six verticals: banking, financial services, healthcare, manufacturing, logistics, and travel. Each vertical has domain-specific engineers who understand the data patterns, regulatory constraints, and operational realities of that industry — for example, HIPAA-aware pipelines in healthcare and PCI-DSS-aware data handling in financial services.

What technologies does Perimattic use for AI development?

Perimattic builds on GPT-4, Claude, Gemini, and open-source models (Llama, Mistral) via frameworks like LangChain and LlamaIndex. Our stack covers vector databases (Pinecone, Weaviate, pgvector), MLOps (MLflow, Weights & Biases), cloud AI services on AWS and Azure, and full-stack integration with Next.js, Node.js, and Python. We select the stack based on your production constraints, not vendor preference.

How do I choose an AI development company?

Evaluate on three dimensions: production track record (ask for shipped systems, not pilots), team depth (data engineers, MLOps engineers, and application developers under one roof), and delivery transparency (sprint cadence, working demos, clear pricing). Ask for verifiable client references on Clutch or G2. Avoid firms that lead with model demos instead of production systems.
