AI consulting & dedicated engineering teams

Production AI,
built to research standards.

Search, recommendations, voice, agents, and evaluation — engineered with the same rigor we hold our peer-reviewed papers to. Whether you need advice, a build, or a dedicated team embedded with yours: we ship the system and leave behind the evidence it works.

01 What we do

Five practices, one standard of evidence.

Most AI projects fail not because the models aren’t good enough — but because no one evaluated the system the way they’d evaluate a paper. Every engagement ships code and the harness that proves it works. Expand any item below to see how we think about it.

Service 01

Search & Recommendation Engines

Search, retrieval, and recommendation systems — with RAG under the hood where it fits. Ours ship with the eval harness that proves they work: golden datasets, regression gates, and drift detection on your real data. No MTEB theater.

Service 02

Voice AI: Reliability & Evals

Voice pipelines that don’t fail at 3am. We instrument every layer — ASR, LLM, TTS — and leave runbooks for the failure modes we’ve seen in multi-tenant production.

Service 03

Multi-Agent Systems

Agentic workflows that survive production. We design topologies from first principles, trace every execution, and benchmark reliability before your first live user hits a planning spiral.

Service 04

LLM Evaluation & Observability

Evals as rigorous as peer review, running in your CI. Golden datasets from real data, power-sized sample plans, and regression gates that actually block bad deploys — not vibes-based spot checks.

Advisory 05

AI Strategy Advisory

For founders, product leaders, and investors who need a senior technical voice in the room — without hiring one full-time.

What we engage on

  • Model selection & build-vs-buy decisions
  • Eval-first product roadmaps
  • Technical due diligence
  • In-flight AI project reviews
  • Senior ML / AI hiring filters

Format

  • 4-week sprint, fixed scope
  • Weekly working sessions
  • Executive-readable final brief
  • Async availability between sessions
02 How we work

A method borrowed from peer review.

We don’t do open-ended retainers or vague “AI transformation.” Every engagement runs on a tight three-phase loop with a written deliverable at each stage.

01 — Diagnose

Read the code. Find the evaluation gap.

We listen, read your code, and write a technical assessment of where the system is brittle and what an honest evaluation would measure. Output: a document you can show your board.

≈ 2 weeks · fixed-fee
02 — Build

Ship code alongside your team.

Pair-programming on the hard parts, clean documentation on the rest. We work in your repos, your CI, your conventions. No black boxes, no leave-behind dependencies on us.

≈ 4–12 weeks · scoped engagement
03 — Evaluate

The harness is the deliverable.

The eval suite we leave behind is the real product. Anyone on your team can run it. Regressions catch themselves. The next AI engineer you hire inherits a system they can reason about.

Tenant attribution & incident triage for a multi-agent platform

Recovered tenant provenance for failed agent sessions. Built the incident response workflow used during platform-wide outages affecting thousands of concurrent sessions.

Evaluation & observability layer for a stealth voice agent

Took a YC-backed founding team from “it usually works” to per-conversation latency and accuracy metrics with a reproducible eval suite they could show investors.

§ What clients say

In their own words.

They found failure modes in our voice pipeline we didn’t know existed — then left us a test suite that catches them automatically. Six months later we still run it on every deploy.

VP Engineering · Vertical SaaS
The first consultants we’ve worked with who pushed back on our roadmap with data. The eval-first assessment changed what we built next quarter — and probably saved us the quarter.

Co-founder · AI Startup, Series A
We’d been burned by agencies that demo well and ship nothing. Lemma worked in our repo, in our CI, at our conventions. The handoff was the cleanest I’ve seen in fifteen years.

R. T.
CTO · Enterprise Document Platform
Their due-diligence review of an AI acquisition target was the most technically honest document our fund has commissioned. We walked away from the deal — correctly, it turned out.

04 Why us

Evidence, not promises.

Most production AI fails not because the models aren’t good — but because no one evaluated the system the way they’d evaluate a paper. Every engagement we take ships with the evidence it works.

We work two ways: consulting — assessments, architecture, and advisory — and dedicated delivery — an embedded team of engineers, product, and DevOps that builds alongside yours for as long as the roadmap needs. Either way, you get senior people whose methods are peer-reviewed and public.

FOR — 01

Startups without an AI team yet

A full AI function — research, engineering, product, DevOps — from day one, without spending two quarters hiring.

FOR — 02

Product teams shipping their first AI feature

A scoped build that lands in your repo and your CI, with the eval harness your engineers keep running after we leave.

FOR — 03

Companies with a stalled AI project

An honest technical assessment of why it’s stuck — then the rebuild, if you want us for it.

FOR — 04

Founders & funds needing a technical read

Due diligence and in-flight project reviews from people who build these systems, not analysts.
