e-commerce

Anyone can launch a shop. Making it earn is the hard part. We start with your brand and the people who love it. Then we build the store that keeps them coming back, and that AI agents can find.

Blue FarmShopify Enterprise store for Europe’s leading non-milk D2C brand, +40 % conversion rate.

Building the best store.

A shop launches once. It has to sell every day after. What decides your year isn’t the relaunch. It’s the depth of data, analysis, behaviour, culture, design, performance and tech that sets you apart. So we build every store in one holistic workflow of five movements. The first one is always Think, and it brings all disciplines together.

  1. 1Think

    It starts with what no dashboard can show you.

    You arrive with a shop that should earn more. We start with what no metric can track: your brand, the people who buy from it, and what would make them come back for years.

  2. 2re:think

    Then we re:think it against the numbers.

    A vision, the result of Think, waiting to be proven. Before we craft your store, we test it against reality: analytics data, consumer insights, category validation, each done by a specialist.

    • Commerce & offer strategy
    • Customer journey & retention model
    • Platform & architecture decision (TCO)
    • Data model & feeds
    • Operations & fulfilment mapping
    • KPI targets, budget & measurement plan

  3. 3Craft

    Then we design a flagship worth the visit.

    Within 3 weeks, the same team that shaped and validated your vision starts crafting your store. Every design decision is rooted in a strategic foundation backed by numbers, engineered to communicate your DNA and your store KPIs, not to decorate.

    • Design system for shop, campaigns & email
    • PDP, PLP, cart & checkout design
    • Content & product storytelling
    • Motion & micro-interactions

  4. 4Build

    Then the same people build it.

    No handover. The team that thinks, decides and designs also builds the store, on Shopify Plus or Enterprise, theme or Hydrogen.

    • Checkout Extensibility & Functions
    • Integrations: ERP, PIM, Klaviyo, payments, POS
    • Markets, B2B, pre-order & drop mechanics
    • Structured product data for AI channels
    • Accessibility, performance, QA & onboarding

  5. 5Run

    Launch is where the money starts.

    Most agencies leave at launch. We stay, if you want us to.

    • Continuous Partnership (phase-based, cancellable)
    • Conversion & AOV experiments
    • Retention & lifecycle: email, SMS, subscriptions
    • Campaign & drop production
    • AI visibility & agentic-channel monitoring
    • Compliance & data hygiene

    • AI visibility & agentic-channel monitoring
    • Compliance & data hygiene

When a brand truly connects with its customers, it creates an emotional bond. That bond is the bedrock for growth. Combining it with the cutting-edge technical experience from our custom projects is what we stand for.

What you can hold us to

  1. ①We don’t hand you books full of theoretical strategy. We create a vision rooted in the real market, starting with clarity, creativity and confidence rather than complex methodology nobody cares about.
  2. ②One team from first thought to running store. We are a focused team by design: no key-account overhead, no passing you from junior to junior. Senior and managing partners, from the first hello to the launch party.
  3. ③An end-game goal and a prototype you can click through and experience within 4 weeks.
  4. ④Decisions every week. No reveal meetings.
  5. ⑤Custom by design. Built around your brand. No copy and paste, nothing off the shelf.
  6. ⑥Not a match for how you work? Cancel in any phase. No retainer, no lock-in contracts, and every phase is designed to be handed over. Because we believe the best partnerships are built on freedom, not on locked-in retainers.
  7. ⑦We build custom products as well, which gives you a Silicon Valley perspective on Shopify that theme shops don’t have, and a breadth of experience traditional agencies can’t match.

agentic commerce

Your next customer might be an agent.

Since March 2026, Shopify publishes products straight into ChatGPT, Copilot and Perplexity. Someone asks for a linen shirt that ships to Berlin by Friday; an agent compares, picks and buys. Whether it picks you has nothing to do with your theme. It comes down to your data.

What changed

  1. 15×

    more AI-driven orders on Shopify in 2025, from a small base. Agents are still under 1 % of retail traffic.

  2. 15–25 %

    of US e-commerce expected to run through agents by 2030 (Bain). McKinsey: $3–5 trillion globally.

  3. 2 protocols

    compete for the job: UCP (Google × Shopify) and ACP (OpenAI × Stripe). Shopify Catalog feeds your products into both.

The storefront doesn’t go away. It becomes the one place an agent can’t replace: your brand, your world. Two frontends on one foundation: the store for people, the data for machines.

Every new trend brings out new experts, including some who have never run a shop. We’d rather bring clarity: a first read of your shop is free, and it’s honest.
