How we work

From first workshop to production in weeks, not years.

  1. 01

    Discover

    Two‑week assessment of your data, systems and highest‑value opportunities. You leave with a prioritized, costed plan.

  2. 02

    Design

    Architecture, security and governance designed up front — so the pilot is built the way production needs to run.

  3. 03

    Deliver

    Senior, cross‑functional squads ship working software in short increments, measured against agreed KPIs.

  4. 04

    Scale

    We harden, monitor and hand over — training your teams so the capability stays in‑house after we leave.

Why mmeleven

A new firm, built on 16 years inside the Fortune Global 500.

mmeleven was founded by Marcin Karpinski, a software architect and engineering leader whose career runs through Goldman Sachs and Wells Fargo, building mission‑critical systems in compliance and credit risk where mistakes are expensive.

That experience is our edge. We know how procurement, security reviews, legacy integration and change management really work inside a Fortune Global 500 company, because we've been on the inside. Our AI programs are designed to survive them.

  • Founder‑led: you work directly with Marcin, our CEO/CTO
  • Vendor‑neutral: we recommend what fits, not what pays
  • Security and compliance built in, not bolted on
  • Fixed‑scope engagements with clear success metrics

Meet the founder

Engineering leadership from Wall Street to AI.

VP of Credit Risk Software Engineering at Wells Fargo · former Compliance Technology Engineering Lead at Goldman Sachs · Software architect

I've spent my career building software where mistakes are expensive: compliance technology at Goldman Sachs and credit risk engineering at Wells Fargo. Working across .NET, React, Java and Scala, I've learned that great systems come from pairing hard engineering with close client relationships and disciplined requirements and project management. mmeleven brings that same discipline to AI.
