Paul Birch and Richard TaylorAd executives and marketing mavens should take a look the recent success of entrepreneurs Paul Birch (co-founder of Bebo, pictured left) and education consultant Richard Taylor (creator of The Assignment Report, pictured right) in setting up and selling their successful Tutpup maths and English games website - and shudder.

Tutpup, a beta (pre-release) product which has just been sold for an undisclosed sum to Mind Candy, gained 250,000 young users worldwide, including 50,000 in the UK within about three months. These learners competed anonymously with one another online, mainly in maths activities, and all this was achieved without a single advertisement or a marketing budget. Word spread online through blogs.
