Empowering Champions

We help build your in-house digital accessibility expertise.

Making your commitment to ensuring digital accessibility feel less daunting.

Tamman believes digital accessibility makes your business better. What is necessary for some is beneficial for all. As a creative, technical, and accessibility services firm, we take a human-centered accessibility first approach when partnering with funded startups, businesses, nonprofits, and enterprise clients.

Why Digital Accessibility Matters…

Drives Innovation

Accessibility in digital products often solves unanticipated problems. Innovations like the typewriter, telephone, text-to-speech, and voice controls were initially meant to include those with a disability. All have found a much broader application in the marketplace.

Minimizes Legal Risk

Many countries have laws requiring digital accessibility. Turns out, doing the right thing also diminishes your potential legal exposure.

Enhances Your Brand

Diversity and inclusion efforts are accelerated when users engage with a clear, well-integrated accessibility commitment.

Extends Market Reach

The global market of people with disabilities is over 1 billion people, with a spending power of more than $6 trillion. Plus, accessibility efforts often improve the online experience for all users.
