What StackSource does
StackSource is a commercial real estate (CRE) lending marketplace platform that connects three categories of CRE participants — investors and developers, lenders, and brokers — into a single self-serve environment for sourcing, matching, and pricing debt capital. The platform is delivered as a web application accessible globally during a free early-access phase, with each user type accessing the platform through a dedicated dashboard module (Investors, Lenders, Brokers) optimized for their workflow.
At the core of the platform is an AI-driven matching engine that processes real-time deal postings from investors and brokers and routes them to lenders based on criteria such as geography, asset type, and loan size. The system is designed to improve with each interaction, leveraging a data layer derived from thousands of historical real estate transactions to surface rate benchmarks, lender behavior trends, and performance metrics. StackSource also claims to be the only CRE lending platform offering daily rate updates across lender types and loan products, paired with a deal tracking feed for market intelligence.
The go-to-market is product-led and horizontally segmented, relying on digital channels (organic social, website, podcast appearances) rather than direct sales. Co-founded by Tim Milazzo (CEO, prior Facebook/Google B2B marketplace experience) and Nathan Wall (CTO), StackSource operated historically as a brokerage before pivoting in 2024 to a SaaS service model. Monetization is deferred during early access — the platform is 100% free — with prior commentary indicating a future shift toward subscription-based SaaS or transaction-based fees. Total disclosed funding across 2016-2021 is approximately $3.3M (Techstars, an undisclosed 2017 seed, NVP Capital in 2018, and a $2.6M round in 2021), and the team remains small at 1-10 employees.

- CREXi: Large commercial real estate marketplace and data platform spanning listings, transactions, and intelligence; overlaps StackSource's CRE data layer and professional user base at greater scale.
Direct peers
