SaaS development and AI integration

We build new SaaS products and add AI to platforms that already have customers on them. Search, drafting, workflow automation and chat, wired into the product you already run.

LangChain, LangGraph, RAG, evaluation

What usually breaks first

Four problems show up in nearly every SaaS engagement we take.

Adding AI without a rewrite

You have a product in production and paying customers on it. Intelligent features go in beside what already works, behind the same auth and the same data model.

Growth that changes the architecture

Query patterns that hold at a thousand users fall over at a hundred thousand. We find the ceiling by measuring it, before your customers do.

Shipping speed without breakage

Faster releases come from tests, reversible migrations and traces you can read at 2am. They do not come from skipping review.

Multi-tenant isolation

Tenant data separation, per-tenant configuration and fair resource limits. Decided once at the schema, not patched into each new feature.

AI features we add to existing products

Each one ships behind a flag, with an evaluation set, and can be turned off without touching the rest of the product.

Search that understands the question

Vector search across your own records, so a user finds the right document without guessing your exact wording.

  • Vector-based semantic search
  • Natural language queries
  • Personalised results
  • Auto-suggestions

Drafting and summarising

Generation, summarisation and rewriting inside the screens your users already work in, not in a separate AI tab.

  • Draft generation
  • Content summarisation
  • Tone adjustment
  • Template expansion

Automated workflows

Routine triage handled by the system: categorising incoming work, assigning it, and flagging what looks wrong.

  • Smart categorisation
  • Auto-assignment
  • Anomaly detection
  • Predictive actions

Conversational interfaces

Chat grounded in your product data, so answers cite the record they came from instead of inventing one.

  • RAG-powered chat
  • Context-aware responses
  • Multi-turn conversations
  • Integration with product data

AI and LLM work

Most of the difficulty in an AI feature is not the model. It is retrieval quality, cost per request, and knowing whether the last change made answers better or worse.

LangChain and LangGraph

Production implementations for document processing, retrieval and agentic workflows.

Vector databases

Pinecone, Weaviate, Qdrant and pgvector, chosen against your read volume.

LLM orchestration

Multi-model routing, fallbacks and cost control across OpenAI, Anthropic and others.

RAG systems

Retrieval that grounds every answer in your product's own data.

Fine-tuning support

Custom fine-tuning for domain tasks, when a general model keeps falling short.

Evaluation and monitoring

Eval sets and production traces, so a prompt or model change is measured before it ships.

Architecture

The rest of the work: making the platform hold the features once they are in.

Event-driven architecture
Decouple services and support real-time features with event streams and async work.
Microservices migration
Decompose a monolith service by service. No big-bang rewrite, no freeze on delivery.
Multi-tenant design
Data isolation, tenant configuration and resource allocation patterns that hold up.
API-first development
APIs designed for integrations, mobile clients and partners from the first endpoint.

Three ways we work with SaaS teams

Pick the one that fits your team. Moving between them mid-engagement is normal.

  1. 01

    Feature development

    We own specific features from design through deployment. Your team stays on the core product while we deliver the new surface.

  2. 02

    Team augmentation

    Our engineers work inside your team, your repo and your standup, adding AI and platform capacity for a defined stretch.

  3. 03

    Architecture consulting

    Guidance on AI integration, scaling limits and technical trade-offs, with the reasoning written down so your team can argue with it.

Adding RAG to a knowledge base

We put retrieval-backed search and question answering into a SaaS knowledge management platform that was already live. The core product kept shipping while we worked.

  • Retrieval runs against the existing document store. Nothing was migrated.
  • Every answer links to the source document, so a wrong answer is traceable.
  • Retrieval falls back to keyword search when confidence is low.
  • The evaluation set was built from real support questions before launch.
