Rules don’t miss bad leads. They miss good ones.
Rules can’t route what they weren’t built for. Mary’s AI lead routing can.
Route / every lead.
Trusted by marketing ops, demand gen, and marketing leadership

Rules-based routing needs to be maintained, updated, and right above every edge case. They never are.
Rep left 3 months ago. Rule still routes to them.
Territory changed. Nobody updated the logic.
Bad data. No rule matched. No rep assigned.
This is what arrived in the system.
No rules covered this. Mary figured it out.

Across 94,000 leads processed, Coralogix’s routing is accurate enough that a human reviewer would have made the same call 19 times out of 20. No rules. Just Mary reasoning through every lead.
130,950 leads. Each one reasoned through and routed to the right rep — without a single routing rule.
What is lead routing?
Lead routing is the process of assigning inbound leads to the right sales rep. Traditional lead routing is rules-based based on territory rules, round-robin assignment, account ownership. Rules-based routing works when the data is perfect and nothing ever changes. In practice, rules miss good leads because they can't reason about context.
Why do rules-based lead routing tools miss good leads?
Rules treat every lead the same way. They don't know that a VP at a strategic account matters more than a junior title at a small one. They break when fields are missing. They can't factor in intent signals, account history, or rep capacity. The leads that get missed aren't the bad ones. It's the good ones with an edge case that gets missed by the rule.
What’s the alternative to rules-based lead routing like LeanData?
AI lead routing. Instead of a rules engine, an AI agent reads each lead — fit, intent, account history, rep context — and decides where to route it. Mary is an AI alternative to rules-based tools like LeanData, built for teams who want reasoning over rules. Same Salesforce/HubSpot backend, different decision layer.
How does AI lead routing work?
An AI lead routing system enriches the lead, matches it to its account, evaluates fit against your ICP, and routes to the rep most likely to close it — with a plain-English reason for the assignment. No more rules to maintain or update. The system adapts as your team and ICP change.
What is speed to lead?
Speed to lead is the time between a lead filling out a form and a sales rep making contact. Faster is better — response inside five minutes correlates with 9x higher conversion than responses inside an hour. Mary routes and notifies 95% of her leads in 42 seconds or less, which is the practical ceiling for human follow-up.
How fast should leads be routed?
Leads should be routed in under a minute, and contacted in under five. The five-minute rule comes from Lead Response Management research showing a cliff in contact rates after five minutes. Rules-based systems typically route in 2–15 minutes depending on complexity. AI lead routing hits 42 seconds consistently.
The right rep. The right context. In seconds — not hours.
