# Andrew Kieve

> Andrew Kieve is the co-founder and CEO of Tolemi, a Boston civic-technology company whose BuildingBlocks platform stitches together the messy, siloed property data that cities sit on and turns it into maps and insights officials can actually act on. Originally launched as OpportunitySpace in 2013 and rebranded after a 2017 run through Y Combinator, Tolemi now helps state and local governments fight blight, enforce housing codes, and protect affordable housing across dozens of American cities. A Stanford and IESE graduate and former Innosight consultant, Kieve has spent more than a decade convincing governments that the answer to neighborhood decline is hiding in their own databases.
