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.

MarketSizer for lead gen agencies - frequently asked questions
How does MarketSizer help lead gen agencies?
MarketSizer gives lead gen agencies a proprietary signal layer - ICP match, purchase intent, and evaluation signals - so every list you deliver is full of accounts actively looking to buy. Clients get pipeline rather than contacts, with 4.2x higher connect rates versus cold lists.
How is this different from buying intent subscriptions for clients?
Single-provider intent data covers one vertical and stitches together expensively into an inconsistent multi-market view. MarketSizer is a proprietary signal layer your clients cannot buy directly, covering 200+ software vendors across 250+ products with vendor-specific evaluation signals, not just topic-level intent.
How quickly can we deliver an enriched list?
Upload a client's ICP criteria and get back a ranked list with intent scores, evaluation status, and renewal proximity. Lists refresh daily for all active campaigns, drawing on 2.5M+ in-market accounts tracked, so every outreach sequence starts from the best possible account set.
Can we show clients revenue outcomes rather than activity?
Yes. Client Signal History delivers account-level signal timelines showing which contacts engaged at which buying stage, so you can demonstrate the connection between your leads and your client's closed revenue - rather than reporting open rates, call connects, and meetings booked.
