"Wagner remained on the board of MAID until 2001 and founded Venda Inc later that year.[6] Venda Inc is provider of e-commerce software originally built using technology from the defunct company Boo.com.[1][4] Wagner had acquired Boo.com for £250,000 in 2000 following the dot-com crash.[12]
...
In 2007 he also founded Powa Technologies, an e-commerce business based on Venda Inc's small business solution, but with additional services for in-store and mobile point of sale and software for mobile payments called PowaTag and PowaPOS, formerly known as mPowa. Wagner introduced PowaTag in 2014, after receiving more than $100 million in funding.[15] Users of the service can make purchases using QR codes, audio watermarks and iBeacons.[6][16]"
So Boo.com -> Venda Inc -> Powa Tech :)
