every visitor id vendor will quote you a match rate between 40 and 60%. heres what most of them wont tell you: a big chunk of that number is fuzzy math.
probabilistic matching uses device fingerprinting, ip inference, and household graphs to guess who someone is. it gets the number up, which makes the demo look good and justifies the usage-based bill. but it also quietly counts bot traffic, data center hits, and scraper sessions as 'resolved visitors.' you pay more, feel like you're getting more, but a meaningful slice of what you're actioning isnt a real buyer.
you find out when your reply rates look nothing like the pitch deck. sequences bounce. reps get ghosted. you start to lose trust in the tool and eventually the whole category.
we built midbound on the opposite bet. deterministic, high-confidence matches only. bot and data center traffic filtered aggressively before it hits the counter. no probabilistic inflation. no fingerprint-based guessing that might be right.
the tradeoff: our match rate looks lower on paper. 10-30% depending on the customer versus the 40-60% others quote. but every identified person is someone you can actually email without embarrassing yourself. the data is enriched and executable from the moment it lands. verified name, role, company, contact. no second enrichment vendor required.
this makes us a fit for a specific kind of team. high-traffic sites where even 10% means thousands of real people a month. high-acv motions where one bad outreach costs more than five missed ones. us-focused gtm where our coverage is strongest. teams who already have the downstream motion figured out- crm, sequencing, ai sdrs, ad platforms, reverse etl- or are actively building it.
for pure volume plays this is probably the wrong choice. youll want something that errs on the side of more matches, even if some of those matches are noise. use the right tool for your motion.
this is also why we agree on waterfall setups. deterministic first for the people you're going to actually contact. probabilistic on top for retargeting and audience sync where a false positive doesnt cost you a relationship. different jobs, different tools.
if youve been burned by match rate claims that didnt survive contact with reality, drop it in the comments. this is the single biggest source of vendor trust problems in the category and nobody talks about it honestly.
