    Our Story

    We don’t just ship code. We build with care, ask the hard questions, and stay accountable for the outcome.

    We’re a boutique team of engineers, consultants, and long-term partners. Every project we take on is treated like it’s our own: designed with clarity, built with discipline, and shaped by a genuine interest in how things work – and how they’ll hold up over time.

    Whether it’s an enterprise-grade WordPress platform, a custom ecommerce system, or an AI-native app, our approach stays the same.

    Andrzej Martens

    Andrzej MartensCEO & Co-Founder

    Co-founded EfficientWeb in 2015 and grew it from two people to a boutique software house. MBA from Beirut, background in e-commerce and consulting. Leads sales, partnerships, strategy - tech through the lens of business, not the other way around.

    What Sets Us Apart

    Ownership

    We take pride in what we build – and responsibility for how it performs. That means sweating the details, not just hitting deadlines. Thinking ahead, not just ticking boxes. And making sure your system works not only today, but a year (or three) from now – even if someone else takes it over.

    Flexibility

    You work directly with the people building your product, so decisions happen quickly and without layers of bureaucracy. Short onboarding keeps things moving fast, flexible billing models fit your situation, and short termination periods mean no heavy commitments.

    Integrity

    We tell the truth – even when it’s inconvenient. If something’s going well, you’ll know. If it’s not, you’ll know that too. We don’t hide behind roles or hide mistakes. We take responsibility, learn, and fix. That’s how trust is built – and how real collaboration works.
