What Kumo does well
Where DealFlow OS fits better
- Reaches owners who have not listed, so the business is not on any broker feed.
- Lists cover every matching business in a market, not only the ones currently for sale.
Where DealFlow OS is strong
Market size published before you buy
Business counts per industry × state are public before purchase, shown next to the U.S. Census County Business Patterns count for the same market.
Browse market countsQuote = delivery, to the record
The count you are quoted is the list you receive. Quotes are built from the same filters and exclusions as delivery, so the number does not shrink after checkout.
Order and pay inside Claude
The DealFlow OS MCP connector lets you search, quote and order a list from a Claude chat, paid with the card you have on file.
How it works in ClaudeFree deal tools
Deal analyzer, SBA loan calculator and LOI generator, free to use on any deal, including ones you find elsewhere.
Open the free toolsDealFlow OS limitations you should know
- Email coverage is low: 0.3% of records nationally carry an email today, concentrated in the markets we have crawled.
- Owner names are available on 1.6% of records.
- No broker-listed or "for sale" inventory: every business in a list is off-market and has not said it wants to sell.
- No financials (revenue, cash flow) per business; you qualify targets yourself.
- Geography: any state, several states, or nationwide in one list.
Which should you use?
Choose Kumo if you want to see every business already listed for sale in one place, with alerts and broker contacts.
Choose DealFlow OS if you want to contact owners who have not listed and are prepared to run outreach at volume. Many buyers use both: a listing feed for in-market deals and an off-market list for direct outreach.
