We’re a boutique company, with lots of experience and a whole new attitude.
We formed TetraLogical in 2019 because we saw the market become more driven by legal compliance than meeting the needs of different people. Compliance is important but it doesn’t guarantee inclusion, so we bridge the gap between the two in intelligent ways tailored just for you.
We like new ideas and finding pragmatic solutions to complex problems. We know that inclusion takes many forms, so our services encompass knowledge, experience, strategy, assessments, and development.
We put people first: you and your customers, our partners and employees, and everyone we meet. TetraLogical is founded on four principles that mean everything we do is:
- Inclusive: We consider everyone and make decisions that exclude no-one.
- Sustainable: We work collaboratively and efficiently to amplify enduring accessibility.
- Ethical: We make decisions for the good of our clients and their customers, our employees, and for the world at large.
- Safe: We respect privacy and manage all data securely.
Every member of our team has more than 10 years’ experience in the technology industry; we’ve all been involved in accessibility since its earliest days on the web.
