Custom AI Development: LLM Pipelines, Agents & Voice AI

We design and build end-to-end AI systems tailored to your workflows from LLM pipelines and voice AI to automation tools.

Most AI projects fail between the demo and production. Not because the technology doesn't work — but because building a working proof-of-concept and building a reliable AI system are two entirely different engineering problems. We specialise in the second one.

What We Build

We design and build AI-powered products end-to-end — from architecture and model selection through to deployment and ongoing monitoring. Every system we ship runs in production for real users, handling real data, under real load.

RAG Pipelines and Knowledge Assistants

Retrieval-Augmented Generation systems that let your LLM answer questions grounded in your own documents, databases, and internal knowledge. We handle chunking strategy, embedding models, vector database selection, retrieval ranking, and prompt engineering — the full stack, not just a demo.

Voice AI Agents

Real-time conversational AI with sub-300ms end-to-end latency. We use Deepgram for speech-to-text, OpenAI or Anthropic for reasoning, and ElevenLabs for natural speech synthesis — integrated over WebRTC or WebSocket pipelines designed for production reliability. We've built voice platforms processing 2000+ calls per day.

Autonomous Multi-Step AI Workflows

Agentic systems that plan, execute, and recover from failures without human intervention. Document classification pipelines, multi-step research agents, automated data enrichment — workflows that replace repetitive knowledge work at scale.

LLM Integrations into Existing Products

Adding AI capabilities to products that weren't built for it. We work with your existing APIs, databases, and infrastructure to add LLM-powered features without rebuilding from scratch.

Document Intelligence and OCR Pipelines

Extracting structured data from unstructured documents — clinical notes, contracts, invoices, emails. We combine traditional OCR with LLM-based extraction to handle the messy formats that rule-based systems can't.

How We Work

Every engagement starts with a discovery sprint — typically one week — to validate technical feasibility and define the right architecture before writing production code. We don't charge for discovery if we don't believe we can deliver measurable value.

After discovery: we scope tightly, build iteratively, and ship working software on a two-week cadence. You see working code in weeks, not months.

Our stack: Python, FastAPI, LangChain, LlamaIndex, OpenAI, Anthropic Claude, Deepgram, ElevenLabs, Pinecone, Weaviate, PostgreSQL with pgvector, AWS, Docker, Kubernetes.

Related Work

We built a real-time Voice AI roleplay simulator for a sales onboarding platform — sub-300ms latency, automated call scoring, and a manager dashboard. Agent onboarding time dropped by 70%.

We also built Cuebo's multi-tenant AI call auditing platform: 2000+ calls processed per day, 90% reduction in manual review time, tenants onboarding in under 2 hours instead of days.

Frequently Asked Questions

Depends on scope. A focused integration — adding an AI feature to an existing product — typically takes 4–8 weeks from discovery to production. A full custom AI system with voice, RAG, and agent components is typically 8–16 weeks. We scope tightly before starting so you know what you're getting into.
Yes. Most of our clients come to us without any existing AI stack. We handle everything from model selection and infrastructure setup to deployment and monitoring.
We're model-agnostic and choose based on your requirements — cost, latency, accuracy, and data privacy constraints. We work with OpenAI (GPT-4o, o1), Anthropic (Claude Sonnet/Opus), Google (Gemini), and open-source models (Llama, Mistral) for cases where data privacy or inference cost requires it.
Yes. We've built HIPAA-compliant AI pipelines using private model hosting on AWS SageMaker with VPC-locked endpoints, ensuring PHI never leaves the customer's environment. We can design for SOC 2, HIPAA, and GDPR requirements from the start.
We offer ongoing retainer engagements for teams that want continued engineering support, feature iteration, and model performance monitoring. We also provide full handoff documentation so your team can operate the system independently.
