About
ConvertKit (rebranding to Kit) is a Boise, Idaho-based email marketing platform built specifically for independent creators — bloggers, podcasters, YouTube creators, course creators, and online educators — rather than businesses. The platform emphasizes list segmentation and automation workflows tailored to creator businesses: nurturing email sequences for new subscribers, product launch funnels, and paid newsletter subscription management. ConvertKit's visual automation builder allows creators to design complex subscriber journeys without code, and its landing page and sign-up form tools are optimized for creator websites. The platform's commerce features allow creators to sell digital products, courses, and paid newsletter subscriptions directly, making it a revenue platform rather than just an email tool. Founded in 2013 by Nathan Barry, ConvertKit bootstrapped to over $30M ARR before raising institutional funding from investors including Craft Ventures. The company serves over 600,000 creators and has paid out over $500M to creators through its commerce features. It competes with Mailchimp, Beehiiv, and Substack in the creator email and audience platform market.

About
Spring, formerly known as Teespring, is a creator commerce platform headquartered in New York City that enables creators to design, sell, and ship custom merchandise directly to their fans. The company rebranded to Spring in 2021 to reflect its broader mission beyond print-on-demand T-shirts into a full creator commerce ecosystem.\n\nSpring is deeply integrated with YouTube's merch shelf feature, allowing eligible YouTube creators to display their Spring products directly below their videos. This native integration makes it one of the most seamless merchandise solutions for video creators on the platform. The company also supports integrations with Twitch, TikTok, and other creator platforms, broadening its reach across the creator economy.\n\nThe platform operates on a print-on-demand model, meaning creators take no inventory risk. Fans browse and purchase products, and Spring handles manufacturing, fulfillment, and customer service. Creators earn a margin on every sale and can customize their storefront branding to match their personal identity.
