AI consulting & engineering

We build AI
that ships.

Prompt Labs partners with teams to design, build, and ship production-grade AI — agents, LLM integrations, and automation that move real metrics, not demos.

Working across the modern AI stack

01 What we do

Services built to reach production

From first strategy to the system running in front of real users — we cover the whole arc.

AI Strategy & Roadmapping

Cut through the hype. We audit where AI actually moves the needle and hand you an ROI-ranked roadmap.

Custom AI Agents & Automation

Autonomous agents and workflows that do real work — research, support, ops — wired into your existing tools.

LLM Integration & RAG

Bring your data to the model. Retrieval pipelines and LLM features embedded in your product, grounded in your knowledge.

Prompt Engineering & Evaluation

Reliable prompts, measured. We engineer, version, and eval your prompts so quality is a number, not a vibe.

AI Product Development

End-to-end builds. From prototype to production app, we ship AI products your users trust.

Fine-tuning & Optimization

Faster, cheaper, sharper. We tune and optimize models to cut latency and cost without losing quality.

02 How we work

A path from idea to production

No 80-page decks. We prototype fast, then engineer for the real thing.

  1. 01

    Discover

    Map your goals, data, and constraints to find the highest-leverage opportunities.

  2. 02

    Prototype

    A working proof of concept in weeks — value before you commit to scale.

  3. 03

    Build

    Production-grade engineering: tested, observable, and built for real traffic.

  4. 04

    Ship & Scale

    Launch, measure, iterate — hand off cleanly or stay on as your AI team.

03 Selected work

Systems we’ve shipped

Anonymized for client confidentiality. Hold a title to open it — the site reads attention; the work rewards it.

Legal & compliance

Regulatory research assistant

A private, on-prem RAG assistant over a dense corpus of regulation — hierarchy-aware chunking, local LLM inference, an inspectable retrieval panel, and an automated eval harness so every answer is auditable.

  • RAG
  • Local LLM
  • Vector search
  • Evaluation
Consumer SaaS

Generative design platform

A generative design engine serving 50k+ users on a serverless backend, with image-optimization pipelines and data ops tuned from gigabytes to kilobytes.

  • Generative AI
  • Serverless
  • Node/TS
Health & fitness

Voice-powered health app

A cross-platform mobile app with speech-to-text food logging and a unified subscription layer reconciled across multiple billing providers.

  • React Native
  • Speech-to-text
  • Payments
Subscription apps

ML pricing & monetization

Dynamic, ML-driven pricing that predicts per-cohort willingness-to-pay, with A/B-tested paywalls and a remote-config safety net.

  • ML
  • Experimentation
  • Mobile

04 Why Prompt Labs

Engineers who ship, not slideware

  • Engineers, not slideware. We write the code and ship the system.
  • Production-first. Evaluation, observability, and guardrails from day one.
  • Model-agnostic. Right model for the job — Claude, GPT, open-source — never vendor-locked.
  • Senior, hands-on. You work directly with the people building it.
