Eval-driven AI engineering for data-heavy SaaS

You shipped AI features. The cost, the quality, and the ROI are still guesswork.

Fixed-fee cost & quality audits for B2B SaaS shipping AI — an eval harness you keep, whether you’re proving a new feature works or your bill is climbing.

Who this is for

B2B SaaS teams — from bootstrapped to Series C — that have shipped an AI feature (customer-facing Q&A, internal copilot, or AI analytics) and aren’t sure the cost, quality, or ROI adds up. If your LLM bill is climbing past $20k/month, the LLM Cost & Quality Audit is the sharp tool; earlier than that, start with the AI Opportunity Audit or the open-source toolkit. Decision-maker: CTO, VP Engineering, Head of AI — or the founder who owns the technical roadmap.

Or — you’re shipping AI features but not sure where the ROI is: ERP exports living in spreadsheets, manual workflows, data scattered across systems. The AI Opportunity Audit maps where AI and automation actually fit — and where they don’t — before you build.

What we do

Productized, fixed-fee engagements. You always know the scope and the outcome.

Start here · two ways in

Paid Discovery / Readout

You already know roughly what you want done. We scope it: feasibility, effort, go/no-go — before you commit to a full engagement.

  • 3–5 day structured technical review of your specific problem or planned engagement
  • Written readout: effort estimate, risks, and go / no-go recommendation
  • Full credit toward any follow-on engagement signed within 30 days
3–5 days

AI Opportunity Audit

You don’t yet know where AI or automation fits in your stack — we map the whole picture and show you where the ROI is. Mapped by a senior data + AI team, not a generic AI consultant.

  • A map of your data flows and systems — ERP, warehouse, spreadsheets, manual workflows
  • Prioritized opportunity register: AI agents vs classic automation vs not-worth-it, scored by ROI × feasibility
  • A build roadmap you can act on — with us or your own team
  • An honest “don’t automate this” section
3–5 days

LLM Cost & Quality Audit (LCQA)

2-week audit of your LLM features: where every dollar goes, and where quality is silently slipping.

~2 weeks

You keep the eval harness — it stays wired into your CI after we leave.

  • Cost breakdown per use case, model, and request component
  • Eval baseline — 50–200 question test set: faithfulness, answer relevance, accuracy@k, p50/p95 latency
  • Optimization roadmap — routing, caching, prompt compression, model tiering — prioritized by impact on your actual spend
  • 8–12 page PDF report
  • Eval harness wired into your CI — regression alerts when faithfulness drops

Mini-Audits / Quick-Win Sprints

Productized one-shot fix when one specific thing is broken.

  • RAG Eval Suite Build — golden test set + faithfulness/recall scorers + CI regression hook + dashboard
  • PII Pipeline Quick-Build — Presidio-based detection and redaction, 8–12 entity types, precision/recall metrics published (engineering artifacts only — your legal team owns regulatory interpretation)
  • LLM Cost Quick-Win Sprint — trace one lever, ship the fix as 3 merged PRs
  • Code + short readout PDF for each
3–7 days

LLM Quality Maintenance Retainer

Managed eval-as-a-service for LLM features in production.

  • Scheduled eval runs on your golden test set
  • Drift alerts to Slack — faithfulness, accuracy, cost, and latency thresholds
  • Monthly PDF report
  • Incident response on drift alerts
  • Three tiers available: Lite — weekly eval + drift alerts · Standard — 2× weekly + incident response · Pro — continuous monitoring + quarterly deep-dive
Monthly retainer

Observability dashboards show what happened. This runs the eval, alerts on drift, and writes the report.

Custom AI Integration

When you need the feature built, not just audited — RAG pipelines, agent loops, and LangChain / LlamaIndex integration on your real data warehouse. Built by the same two senior engineers, no junior handoff.

Fixed-fee · scoped in a written proposal within a couple of business days

Larger Builds — on request

Available for teams ready to build from scratch.

  • Production RAG MVP with eval harness wired into CI — 4–6 weeks
  • AI Analytics Copilot — natural-language Q&A on your data warehouse, RAG + text-to-SQL hybrid with eval — 6–8 weeks

Scope and fee discussed in discovery.

Every engagement is fixed-fee, scoped up front — you’ll have exact scope and pricing in a written proposal, usually within a couple of business days.

Also work on

AI cost is the hook — but it’s rarely the only thing bleeding. These come up in discovery; we take them on as part of an engagement, or as a standalone Paid Discovery.

Start with the open-source toolkit

The same eval harness we run in audits is public on GitHub (MIT). Self-host it, wire it into your CI, set your own quality bar. When you want it run for you — continuously, with drift alerts — that’s the retainer.

What productized means

  • Fixed fee — no hourly billing, no surprise invoices
  • Locked timeline — if scope expands, we cut scope, not extend the timeline
  • Clear acceptance criteria in the contract — audits: baseline measured, eval harness wired, roadmap delivered; builds: metric targets on the system we build with you (faithfulness, recall@k, cost reduction)
  • ≤ 2h/day of your team’s time during delivery

About

A two-person senior team — data + AI engineering for data-heavy SaaS.

Pure data engineers can’t ship production RAG. Pure AI engineers can’t ship on a real data warehouse. The combination — data engineering at scale plus eval-driven RAG — is genuinely rare. It’s what this team is built on, and exactly what data-heavy SaaS teams need in 2026.

Between us: 8 years of Lakehouse-scale data platforms and production GenAI evaluation — petabyte-scale infrastructure, then production RAG with measurable quality SLAs. Two senior engineers, both with commercial AI experience — one data-and-AI, one AI-focused.

Fully remote, based in the EU. Async-first — US & EU clients, minimal meeting load.

You work directly with both of us on every engagement. No junior handoff, no account manager in the middle.

Engineering scope only — we build the artifacts; your legal and compliance team owns regulatory interpretation.
