I've not used the service in anger, but lots of people tell me it's very good.
I want to talk about the logo for a little bit.
It's great, isn't it? Simple, fun, tonally right. Works well on apps, on the side of cabs, on leaflets. The form does a reasonable job of describing the function. It even has a touch of humour about it.
I walked past a Hailo driver office today. That looked good too. There even looked like there was a place to get your cab washed out the back.
All good. Bigger brands could learn from this small one.
(The blog is worth a read too.)
