A blank MRR means the tool publishes a price but no revenue. Absence is information: the
tools that show revenue are a minority of the market, which is exactly why the ones that do are worth indexing.
Where this tool sits
Tools in this part of the chain build the list: lead databases, enrichment, and intent signals such as a job change or a funding round. They are usually priced per credit or per contact, which is why their entry price says little on its own.
How to read this page
Entry price is the cheapest monthly tier with a public price — not the tier most buyers end up on.
Latest monthly revenue is the most recent figure the tool published; the trail above shows every
observation the index has, with its date.
Tiers counts monthly plans found on the pricing page. A tool with one tier has one price to defend.
If the price column says no monthly price recorded, the tool quotes instead of publishing — above
$199 that is the norm in this market, not a gap in the data.
