Spacious, the London property tech startup founded by Entrepreneur First alumni Tushar Agarwal and Tom Watson, together with ex-advisor to the British Prime Minister Rohan Silva, has closed £500,000 in seed funding. The round was led by Spire Ventures, the VC fund set up by Faisal Butt and ex-Dragon James Caan, while Spacious says the additional capital — its first external fundraise, not including involvement in the Entrepreneur First programme — will be used to boost engineering talent and further build out its platform.
