MASHABLE - Aug 18 - Clover, Whim, Pure and HowAboutWe's Tonight app offer on-demand functions which cut to the chase so users can aggressively get on each others' calendars. Clover just closed $2M in funding (bringing total investment to $4M). Close behind Clover is upstart Whim, which launched in LA in 2014. Markedly different from Whim and Clover is the unabashedly more hookup-focused Pure, which is so radical and in-the-moment in its "demand" nature, that there are actually no profiles or Facebook integration. Having raised 10 times less investment capital than Clover ($400K versus $4M), Pure is already cash-positive.
