As answered by people managing CodePen and VaultSomm.
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.
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.
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.
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.
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.
