The firms that win with AI in this cycle won't be the ones with the best models. They'll be the ones with the best data.
My Demo Day podcast/YouTube guest today is Michael Mandel, co-founder and CEO of CompStak.
Key takeaway: clean data is the moat - AI is the multiplier.
CompStak spent 14 years crowdsourcing lease and sales comps from nearly 50,000 brokers and research professionals. That foundation is what makes their AI tools actually useful rather than just impressive.
The practical applications worth knowing about: natural language search across 1.3 million lease comps, AI-powered rent estimations weighted by hundreds of comparable deals, and dynamic market narratives that replace what used to take an analyst team days to produce.
For institutional players, the real value is portfolio benchmarking - seeing whether your rents, concessions, and lease positioning are above or below market. Not against your own assumptions, but against actual comp data.
Coming in 2026: enterprise clients will be able to plug CompStak data directly into their own internal platforms, and a new prospecting tool for tenant rep brokers that surfaces opportunities based on upcoming lease expirations and tenant growth patterns.

More from AI for Real Estate
Most CRE sponsors treat AI as a collection of separate tools but the firms pulling ahead are building something fundamentally different: a single integrated stack where every layer of the operation, from deal sourcing to asset management, feeds the same system.
Most commercial real estate firms believe AI will transform their business. Only 9% have done anything about it. That is not a technology problem. It is a workflow problem - and no one is asking the right question to close the gap.
Most CRE firms say they're using AI. What they mean is someone has a ChatGPT tab open.
CRE brokerages have spent tens of thousands configuring Salesforce. Nobody uses it. The data is stale, the pipeline is fiction, and the analyst is entering last week's emails at 8pm to stay compliant.
Most development firms are competing over 1.5% of US land.
