The BBC is reporting that voice-to-text firm Spinvox is for sale. Invesco Perpetual, which has invested £759,000 in the firm, says its investment is now worth 90% less but adds “the business has been put up for sale, and it is possible that, should a good sales price be achieved, the new valuation may be exceeded”. Spinvox has asked the investment firm to withdraw the statement. [Sources: BBC News; Invesco Perpetual report via Reuters]
