LLM INTEGRATION SPRINT — AI SPRINT
GPT-4, Claude, Gemini, or open-source LLMs wired into your product with prompt engineering, guardrails, and evals.

WHAT YOU HAVE AT THE END
Fixed price · Everything stays with you
Here’s what this looks like in practice:
CHAT FEATURE
You ship a chat assistant inside your product
Users ask questions in plain language. The LLM answers based on your content — with guardrails that prevent it from going off-topic or generating harmful output.
SUMMARISATION
Long documents → structured summaries users can act on
Your users paste in a contract, report, or article. The system returns a structured summary in the format you define — highlights, action items, or key clauses.
CLASSIFICATION
Incoming data routed automatically by content type
Support tickets, form submissions, or documents arrive and get classified and tagged instantly — without a human reading each one.
CONTENT GENERATION
Drafts generated from your templates and data
Your team defines the template and data inputs. The LLM generates first drafts — proposals, emails, product descriptions — ready for human review and approval.
Every engagement starts with a free 45-minute diagnostic. We map your situation and tell you whether this sprint is the right fit before you spend a dollar.
Blueprint sprint has a money-back guarantee. If the agreed deliverable isn’t met, you pay nothing. No conditions, no argument.
Everything built during the engagement — code, models, documentation — is yours. No lock-in, no ongoing dependency.
THE PROBLEM
API calls aren't a product
“"We connected the API in a day. But outputs are inconsistent and we've had two incidents where it said something wrong to a customer."”
VP PRODUCT
No eval framework
“"We don't know if our prompts are getting better or worse. Every update is a guess."”
ENGINEERING LEAD
Cost unpredictability
“"We launched the feature and the API bill tripled in two weeks. We had to throttle it and customers noticed."”
CTO
Guardrails as afterthought
“"Legal found out we'd shipped without content moderation. We had to pull the feature."”
PRODUCT MANAGER
WHAT THE BLUEPRINT SPRINT UNCOVERS
Prompt engineering is more than writing prompts
Prompt architecture — version control, structured testing, regression detection — is what separates a reliable AI feature from a fragile one.
Guardrails prevent incidents, not embarrassment
A content filter isn't about brand safety. It's about legal liability, user trust, and not being the company in the breach report.
Cost controls belong in the architecture
If cost controls are retrofit after launch, they're already too late. The sprint includes rate limiting and cost monitoring from the first build.
Evals are the only way to improve prompts
Without a test suite, every prompt change is a production experiment. The eval framework lets you measure whether a change is better — before users see it.
WHY THIS IS DIFFERENT
An LLM wired to an API endpoint isn't a product. It's a liability.
Most teams treat LLM integration as an engineering task: call the API, parse the response, display it. The feature ships. Then the incidents start — hallucinations, off-topic outputs, unexpected costs, and a support ticket nobody knows how to explain.
Every integration we build includes a prompt architecture that's versioned and tested, guardrails that prevent the feature from saying anything it shouldn't, cost controls so the bill doesn't surprise you, and an eval framework your team uses to measure accuracy before shipping any prompt change.
THE METHODOLOGY
The AI Build System
Four phases. Every AI engagement, every time.
Map and clean your data sources. Define accuracy targets and query patterns before writing a line of code.
Train, fine-tune, and test the model on your corpus. Iterate until the target accuracy is hit.
Ship to your environment — cloud or on-prem. Integrate with your product or internal tools.
Live dashboard tracks performance from day one. You see what's working and what needs attention.
After handoff: your team updates data, the system retrains — no ongoing dependency on ProductQuant.
WHAT YOU GET
A production-ready LLM feature inside your product — with prompt architecture, safety guardrails, cost controls, and a repeatable eval framework.
FIT CHECK
The situation
Product teams who want to ship an AI-powered feature (chat, summarisation, generation, classification) without building the infrastructure themselves
What changes
You have a production-ready llm feature inside your product — with prompt architecture, safety guardrails, cost controls, and a r.

I work with B2B SaaS product and operations teams to build and deploy the systems they need — without consuming their engineering capacity or waiting 18 months for the roadmap.
Every engagement starts with a free diagnostic and a scoped blueprint sprint with a money-back guarantee. If the sprint doesn’t hit the agreed target, it costs you nothing.
