Harry Brignull

I'm a UX consultant, researcher and fractional design leader. I coined the term "dark patterns" in 2010 and wrote the book on deceptive design. I've worked with Mozilla, Spotify, The Telegraph, HMRC and others.
I usually work with clients as an ongoing advisor, or on small, focused projects. My current clients include: Amurabi, a legal innovation studio; a Brighton-based SaaS company; and a fintech startup in stealth mode. Would you like to know more? Get in touch.
I provide expert witness and consulting services in litigation involving manipulative, coercive or deceptive design. Selected cases include Nichols v. Noom (2020, $56 million settlement), FTC v. PCH (2023, $18.5 million settlement), and FTC v. H&R Block ($7 million settlement). View more.
