About CharacterQuilt

Computer use agents to deploy enterprise marketing campaigns

CharacterQuilt builds computer use agents to deploy enterprise marketing campaigns. Marketers today don’t actually do much marketing at all. Today, over 80% of time spent on launching a marketing campaign is actually ops work: tweaking automation flows in Pardot, configuring audiences in LinkedIn, or wiring HTML emails in Marketo. What’s crazy about enterprise marketing is companies pay agencies millions of dollars just to deploy campaigns in their systems — and they still have to wait weeks for each one. CharacterQuilt is AI infrastructure for marketing teams: a brain that learns your brand, and agents that operate your existing tools. Marketing campaigns that used to take 3 agencies, 10 tools, and 6 weeks are now being built, designed, and deployed from CQ in an hour. Customers submit a brief like they would send to a human teammate or marketing agency, and they get back fully designed and deployed campaigns. Teams like 1upHealth, ABC Fitness, and Emplifi use us to: 1-) Build segments/audiences faster 2-) Create on-brand creative (AI is terrible at staying on-brand) 3-) Deploy campaigns automatically into HubSpot, WordPress, LinkedIn etc. We replicate your brand guidelines, deeply understand past campaigns, and work inside your systems. If you run demand gen or lifecycle at a B2B/B2C company and want to ship campaigns faster, send us a brief and we’ll build it in 15 minutes.
