Custom Web Design, Digital Accessibility & ADA Compliance – 29 Years of Digital Excellence

Founded in 1997 in Burlington, Vermont, Propeller is a digital agency specializing in web development, digital accessibility, and online marketing. We build creative, ADA compliant, AI-friendly websites that entice, engage, and convert.

Digital only. No shortcuts.

Digital isn't a bolt-on for us – it's all we do. No logos, no brochures, no website factories. We design and build custom digital experiences with precision, and we've been doing it long enough to have seen every major shift coming before it arrived.

Mobile. Accessibility. Now the Agentic Web. Our clients are always ready.

Accessibility that goes deeper than compliance

While others reach for a plugin, we build to WCAG standards from the ground up. Behind our dev team is Accessibility.Works – our dedicated accessibility consultancy with over two decades of experience in auditing, remediation, and VPAT authoring for organizations worldwide. Our accessibility lead sits on the W3C's WCAG working group.

That's not a credential we mention lightly. It's what separates a compliant website from one that actually works – for people with disabilities, for seniors, for search engines, and increasingly, for AI agents too.

SEO and AEO built in from the start

Accessible, well-structured websites perform better in search. And as AI agents become active users of the web, that same foundation drives AI Engine Optimization as well. We've been connecting these dots for a while now.

Vermont craftsmanship. Real partnership.

Straight talk, responsive communication, no surprises. Our team has worked together for years and we take the time to understand your brand before we touch a pixel. We're not here to be a vendor. We're here to keep you ahead.

Let's build something together that entices, engages, and converts.
