What Customily does

Customily, Inc. is a SaaS product personalization platform founded in 2018 and headquartered in St. Louis, Missouri, enabling eCommerce merchants to offer customized products to shoppers directly on storefronts built on Shopify, Etsy, WooCommerce, Amazon, Shoplazza, BigCommerce, Magento, Squarespace, Wix, Salesforce Commerce, Walmart, and additional channels via API or iFrame. The platform renders real-time product previews during the customization flow, generates print-ready production files automatically on order, and connects directly to a network of 20+ print-on-demand providers including Printful, Printify, Gooten, Gelato, CustomCat, and Printbelle. Underlying technology includes the Customily.js JavaScript preview library, a REST-based Personalization Details API (V2), a Design Studio API with Swagger documentation, and a Standalone iFrame integration method, all authenticated via JWT Bearer tokens.

The company monetizes via a hybrid subscription-plus-transaction-fee model: $49/month for standard platform integrations (Shopify, Etsy, WooCommerce, Amazon, Shoplazza), $299/month for standalone/custom platform integrations, plus usage-based transaction fees that decline from $1.00 to $0.10 per unique personalized item as volume grows. A 10% recurring affiliate program and demo-led enterprise sales motion supplement the product-led growth engine. Customily also offers an AI-augmented design studio with generative image tools (DALL-E, Nano Banana), computer-vision features (cutout, background removal), and an expanding set of personalization types including word clouds, star maps, street maps, crosswords, and word search puzzles.

At 11-50 employees and bootstrapped-scale funding (a $1.6M Y Combinator/Imagination Capital/Start-Up Chile seed in 2021 and an Arch Grants award in 2019), Customily has accumulated 21,600+ installs worldwide, processes 54,000+ daily custom orders, and reports $1.8M+ in daily GMV flowing through its platform. Its named customers span enterprise brands (Johnnie Walker, HBO, Mattel, Stanley, Heinz, Montblanc, Kipling, PaperSource) alongside a long tail of small and mid-market eCommerce sellers and POD merchants. The company is led by co-founder Alejandro Lozdziejski and founder Martina Möring.

Customily competitors and assessment

Company assessment

Direct peers

Zakeke: Zakeke is a product personalization and 3D customizer platform for e-commerce, with live previews, design tools, and integrations to Shopify, BigCommerce, and WooCommerce. It is the closest direct competitor to Customily, addressing the same merchant use cases with overlapping pricing tiers.
Custom Product Designer by Modifier: Modifier's Custom Product Designer is a Shopify-focused product personalization app offering live previews, text/image options, and conditional logic. It targets the same Shopify personalization segment as Customily with similar SMB and enterprise use cases.
Teeinblue: Teeinblue is a product personalizer focused on print-on-demand and apparel merchants on Shopify, Etsy, and Amazon. It competes directly with Customily's core POD personalization workflow including live previews, mockups, and POD order routing.
Customizer by Bold Commerce: Bold Commerce's Customizer is an enterprise-grade product customization tool for Shopify and BigCommerce merchants. It overlaps Customily's enterprise tier with deeper checkout and commerce bundling.

Emerging players

Dynamic Mockups: Dynamic Mockups automates mockup generation for POD merchants via API, addressing adjacent workflow needs. While not a full personalization suite, it overlaps Customily's automatic print file and mockup capabilities for a subset of merchants.
Inkit: Inkit offers product personalization and direct mail automation, with overlap in personalization workflows for e-commerce and enterprise. It serves a narrower set of use cases than Customily but competes for the same merchant wallet.

Broad incumbents

Printful: Printful is a leading print-on-demand fulfillment provider and a direct integration partner of Customily. It is comparable as a broader commerce platform that increasingly bundles customization features, potentially competing or partnering depending on merchant needs.
Printify: Printify is a major POD marketplace integrated with Customily. It overlaps Customily as a broader commerce platform serving POD merchants, with its own growing catalog and design tooling that intersect with personalization workflows.
Shopify: Shopify is the primary e-commerce platform that hosts Customily's app and billing. It is comparable because Shopify's own product options/variants and emerging AI personalization features represent the largest competitive and platform risk to Customily's positioning.

Others

Spocket: Spocket is a dropshipping and POD supplier platform serving Shopify and WooCommerce merchants. It is comparable as an ecosystem participant addressing the same SMB merchant base, though its core focus is supplier sourcing rather than personalization tooling.
