D2C Developers

D2C Developers is a Shopify-exclusive development agency for direct-to-consumer brands. No WordPress, no Webflow, no "a little bit of everything." Every project runs on Shopify, which is why we solve in days what generalist teams spend weeks figuring out.

The agency is founder-led. You work directly with John-Michael McCasland, a Shopify engineer since 2017 who has built for 9-figure brands: managing Shopify and ecommerce development at Boston Proper (where he launched Shopify Collectives with 20+ partner brands), building subscription software for Hint Water's $90M+ subscription program, and engineering subscription tools at Upscribe used by Athletic Greens, Ryze and Four Sigmatic.

We work across the full Shopify stack: themes, Shopify Functions, the Admin and Storefront APIs, and POS. We take on the projects that don't fit neatly into an app: full store builds and redesigns, migrations onto Shopify, custom subscription, bundling and checkout logic, performance and Core Web Vitals work, accessibility and ADA remediation, and ongoing development retainers.

Recent results: Aimee's French Market increased conversion rate 45% after we migrated 7,000+ customers and 20,000+ orders from Squarespace to Shopify. Clients include Nerdwax (on retainer since 2022), KindThread, The Virgin Organic, 4ORE Hydration and Plenty Postpartum.

Projects start at $5,000.
