I met Caelen King at the recent Web 2.0 Expo conference. Caelen is a member of the Baltimore Software alumni and has recently launched http://whatclinic.com, a place to Compare Dentists and Cosmetic Clinics Worldwide.
Sounds dull (unless you have a toothache or want bigger breasts) but Caelen really knows his customer acquistion stuff and has some very clever ideas about growing his market. Great to see Irish companies competing in this kind of space.
WhatClinic.com has recently expanded into Dentists in the UK and Plastic Surgery in the UK.
