YieldStack's answer
AI integrations supporting the platform’s workflows.
Totsum.app's answer:
DuckDB for the data and llama.cpp for the model, both running inside the app on your own machine.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Totsum.app's answer:
The AI runs on your own machine, and the answers leave as a report built to be checked by a person: the rows behind every chart, the query written out step by step, and a shortlist an expert can validate.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
YieldStack's answer

Totsum.app's answer:
People who work on data files they cannot upload: consultants and independent professionals under confidentiality agreements, and anyone who wants a first look at a file before handing it to an analyst.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
