Snowdevil built better snowboard software, then sold it as Shopify

In 2004, programmer Tobias Lütke and Scott Lake set out to sell snowboards online as Snowdevil, but every available e-commerce platform of the era — Yahoo Stores, Miva Merchant, osCommerce — was either too rigid, too expensive, or built with what Lütke considered the wrong assumptions about how a merchant should be able to customize a storefront; Yahoo Stores in particular restricted sellers to trivial styling options and took repeated clicks to add a single product.

Rather than accept those limits, Lütke spent roughly two and a half months building his own e-commerce software from scratch using Ruby on Rails, then a brand-new framework, giving Snowdevil a shopping cart, checkout, inventory management and admin backend built the way he thought a merchant tool should work — purely as infrastructure to run his own snowboard shop, with no plan to sell it to anyone else.

As Snowdevil operated, other online retailers who saw the store's backend started contacting Lütke and Lake not to buy snowboards but to ask how they could license the software running it. After enough of these unsolicited requests, Lütke told Lake over the phone that they might be in the wrong business — they shut down the snowboard retailer and rebuilt the company entirely around the platform, renaming it Shopify and launching it publicly on 2 June 2006 with a new template language, Liquid, letting merchants customize stores without writing code.

When rivals asked to license it, he shut the store and rebuilt the company around the tool — the unsolicited demand proved the platform was the real business.

Existing platforms were so rigid that building a replacement was necessary, creating a tool that solved a general pain point.

The tool was battle-tested by real store operations, making it credible and attractive to other merchants.

Unsolicited requests from unrelated retailers proved the demand was for the tool, not the snowboards.

Shutting down the original business let the team focus entirely on the more promising product.

When outsiders ask to use your internal tool, that demand may signal a bigger market than your original business.

Shopify reached roughly $8,000 in revenue by October 2006, grew to about 2,000 accounts with 100 active merchants by 2007 after switching from a commission model to flat-rate subscriptions, hit $1 million in annual revenue and cash-flow positivity by 2008, and reached 80,000 customers before its 2015 IPO, which raised $131 million at a $1.3 billion valuation.
