FIND -WelcomeLend Dealflow: uses machine learning to build out deal flow pipelines that allow the WelcomeLend team to find relevant deals.
PLACE- WelcomeLends Match: using WLs predictive data intelligence, WL Match finds the right capital source at the exact right time. We scan ~38 million deeds to see who is lending on what/where/when. Knowing propensity to lend is critical in finding mutually incentivized/motivated parties.
