Raj Singh is a London-born computer scientist and former IBM engineer who runs JLL Spark with an explicit optionality and resilience philosophy, intentionally investing in external startups that sometimes overlap with JLL's internal products because he argues large clients need multiple solution paths rather than a single in-house stack. He brings an unusually specific focus on the AI-data center-real estate nexus and is openly exploring blockchain tokenization concepts that could fractionalize real estate ownership for smaller investors, positioning JLL Spark as what he calls a hidden gem in proptech that many founders don't realize is an active venture investor.
