Deliver clients pipeline that's already in-market.
MarketSizer gives lead gen agencies a proprietary signal layer - ICP match, purchase intent, and evaluation signals - so every lead list you deliver is full of accounts actively looking to buy.
Used by lead generation and demand generation agencies across B2B SaaS markets
Your clients want pipeline. You're delivering contacts.
Firmographic lists and intent subscriptions get you names. What clients need is accounts that are actively in-market - and the signals to prove it.
Lead lists are built from firmographics, not buying signals
Filtering by company size, industry, and headcount gives you a universe of accounts - not a set of buyers. Clients get contacts, not conversations.
Intent data is expensive and siloed
One intent provider covers one vertical. Stitching together a multi-market view is expensive, inconsistent, and still doesn't show who's actively comparing vendors right now.
Reporting is activity-based, not outcome-based
Open rates, call connects, and meetings booked tell clients nothing about revenue attribution. You can't connect your leads to closed pipeline without better signal data.
A proprietary signal layer your clients can't buy anywhere else.
