Trutap, a leading UK mobile startup which made the TechCrunch 40 list in 2007, is letting go almost 80% of its 30 staff after failing to hit its window for a second round of funding. A skeleton staff will keep the social apps Java application for mobiles available prior to a sale or new investment, only a month after its re-launch. The startup was orphaned after its first investor Tudor Ventures, a hedge fund hit hard by the economis crisis, put in a rumoured $6m but could not come back for a second funding round. And today the UK startup scene was also hit by news that review site Reevoo is putting a fifth of its staff jobs on an “at risk” list.
