BigStep AI Systems

Most AI demos break in production. Ours don’t.

BigStep helps SaaS and enterprise teams build scalable AI systems using LangChain, LangGraph, AI agents, and enterprise workflow orchestration.

The production gap

Why most AI projects fail in production.

Prototypes work. Production breaks. These are the eight failure modes we see most often when teams move from demo to deployment.

Unreliable workflows

Agent loops drift, tool calls fail silently, and there's no recovery path.

Hallucinations

Outputs look fluent but invent data — fatal in regulated workflows.

Broken integrations

Brittle glue code between AI and CRM, ERP, and internal APIs.

Lack of governance

No approval gates, no audit trail, no policy alignment.

Poor scalability

Notebook-grade pipelines collapse under real traffic and concurrency.

Disconnected systems

AI sits on the side, not embedded in the operating workflow.

Weak observability

No traces, no evals, no way to know what went wrong — or right.

No structured handoff

Outputs aren't validated or typed — downstream systems can't consume them.

LangSmith · observability

Production-ready AI you can actually inspect.

Every BigStep production graph is instrumented with LangSmith traces and regression evals — so buyers can inspect runs in a 30-minute technical review.

Distributed traces

Full LangSmith trace history across graphs, agents, tool calls, and retries — ready to share with stakeholders.

Run historySpan timingToken costs

LangSmith Evals

CI-integrated regression testing and guardrail checks — fail builds when quality, latency, or cost regress.

Regression eval setsGuardrail checksCI/CD gates

Prompt versioning

Versioned prompts with deployment tagging — roll forward and back safely without redeploying the app.

LLM cost engineering

Cost-engineered by design — not as an afterthought.

A dedicated cost-optimization layer is built into every BigStep AI System — keeping unit economics defensible at scale.

Semantic caching

Reuse previous answers for semantically equivalent queries — cutting tokens, latency, and spend on repeated traffic.

Embedding-keyedTTL-awareHit-rate tracked

Frugal model routing

Simple queries to small/cheap models. Complex or critical flows to frontier models. Routed automatically — measured continuously.
