As answered by people managing YieldStack and VaultSomm.
YieldStack's answer
The largest CRE Lenders in the USA
VaultSomm's answer:
VaultSomm's core customers are high-net-worth collectors with 500–7,500+ bottles who buy at auction, work with a CPA or estate attorney, and treat their cellar as a financial asset. Primarily US-based.
YieldStack's answer
AI integrations supporting the platform’s workflows.
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.
VaultSomm's answer:
Most wine apps are built around discovery - finding wines to buy, reading tasting notes, logging what you drank. VaultSomm is built around ownership - what your collection is worth, what you'd owe if you sold, and what your accountant, insurer, and estate attorney actually need from you.
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.
VaultSomm's answer:
Your collection has crossed the line from hobby to asset - and you need software that knows the difference.
Once your cellar is worth more than $10,000, three things become real financial risks:
Tax exposure - selling wine without tracking cost basis and holding period is the same as selling stock without knowing your cost basis. The IRS expects you to know.
Insurance gaps - most homeowner policies cap wine coverage at $1,000–$5,000. You need current FMV documentation to get properly covered.
Estate complexity - wine has no automatic step-up in basis at death. Without an itemized inventory, your heirs inherit both the bottles and the tax problem.
VaultSomm is the only platform that addresses all three - in one place, built specifically for fine wine, with the aesthetic and privacy standards collectors expect from a private banking portal.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
VaultSomm's answer:
VaultSomm is built for high-net-worth collectors whose cellar has crossed from hobby to financial asset - typically $10,000–$500,000+ in value. They sell at auction, work with a CPA or estate attorney, and need software that goes beyond inventory tracking. Three profiles: the serious collector who buys regularly and needs valuation clarity; the estate planner who needs documented FMV for heirs and insurers; and the active seller who tracks cost basis and capital gains for tax time.
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.
VaultSomm's answer:
VaultSomm was founded by a CPA who saw the same problem repeat across client portfolios - significant wine collections with no cost basis records, no current valuations, and no documentation an insurer or estate attorney could use. The tools collectors relied on were built for discovery, not financial accountability. VaultSomm was built to fix that: professional-grade portfolio management, live market valuations, and IRS-ready tax reporting, built by someone who knew exactly what was missing.
