What Yelling Mule does
Yelling Mule is a Boston-based web design and digital marketing agency that has delivered custom responsive website design, branding, digital marketing campaigns, and ongoing website maintenance to businesses of all sizes since being formed in March 2010 through the merger of Northie Interactive and Jason Craig Boston. The firm's client base spans enterprise and SMB accounts across financial services (Webster First Credit Union, Forward Financing, Wolf & Company), healthcare (Mass General Brigham), education (MIT, reacHIRE), food and beverage (Harpoon Brewery, NETTTS), manufacturing (Kaswell Flooring), and emerging technology (Golden Goose cryptocurrency platform, Market Meditations newsletter). The company employs approximately 8 team members under founder and CEO James Shiner, with co-leadership from Creative Director and Partner Nicki Haylon.
The company's core technology asset is MuleFlex, a proprietary drag-and-drop WordPress page builder that supports custom templates, third-party API integrations, and bundled ongoing services including phone and email support, real-time backups, malware protection, and SEO reporting. Yelling Mule also builds custom integrations for individual clients, such as a centralized financial rates system for Webster First Credit Union and a subscription/user management platform for Market Meditations integrating Stripe, ActiveCampaign, and Discord. The 8-person team operates from the company's current headquarters at 175 Portland Street in Boston's West End (relocated March 2022), with a secondary creative space in Salem, MA.
Revenue is generated through a hybrid model combining one-time project fees for web design and branding, retainer-based digital marketing engagements, recurring website maintenance subscriptions, and MuleFlex subscription revenue. Go-to-market is direct sales-led, with client acquisition through a "Request a Quote" website form, phone and email contact, and dedicated account management. The company operates as part of the informal "Mule Group" family that includes sister companies Mule Media (digital marketing agency, launched 2016) and Mule Force (cybersecurity, launched 2017), plus the Mule CRM product — enabling cross-referral of adjacent services. No external funding rounds have been disclosed, and the company is privately held by its founder.
