You’ve had this week.

Every store hits the point where the app store runs out. It usually looks like this.

  1. MonThe theme
    What happens

    You want to swap the homepage banner for Friday’s sale. Three freelancers have patched the theme, and the edit breaks the mobile menu. The banner waits two days for a developer.

    What we do

    We rebuild the theme with sections your team edits in the Shopify editor. No ticket, no wait.

  2. WedThe missing feature
    What happens

    Wholesale buyers need their own prices and a minimum order. Three apps each cover part of it, and at checkout they fight over the same cart.

    What we do

    We build one custom app that does exactly your rule, on Shopify’s current APIs.

  3. FriThe sale
    What happens

    The drop opens at 9:00. By 9:05 the stock sync is behind, you oversell, and next week is refunds and apology emails.

    What we do

    We build and test the integrations so the store holds when the traffic comes.

If an app already does it, install the app. When none does, bring it to us.

What we build for you.

Theme development

A fast storefront your team can edit without calling us.

Custom apps

The feature your store needs and no app sells, built on Shopify’s current APIs.

E-commerce

Builds, migrations and integrations that hold up on sale day.

Marketing

Campaigns and conversion work judged by revenue, not clicks.

Senior people, small team.

Software and AI/ML engineers plus e-commerce experts, each with 10+ years in the field. Before Shopstack, we were directors and held other senior roles.

10+ years

  • Software

    Designed, built and run production systems end to end.

  • AI / ML

    Taken machine-learning work from prototype to production.

  • E-commerce

    Run online stores and the marketing that feeds them.

  • Leadership

    Led teams and owned results as directors and senior leads.

  1. We ship our own software.

    Discount Genie runs on code we write, host and support ourselves.

  2. You talk to the people who build it.

    No account managers in between. The engineer on your project answers your email.

  3. Few projects, full attention.

    We keep the number of outside builds small so each one gets senior hands.
