Know every active evaluation, renewal, and displacement opportunity in your category.
MarketSizer maps the entire buying landscape for your software category - who's in-market, who's renewing, and who's unhappy with the incumbent.
Used by GTM teams at SaaS vendors across 200+ tracked vendors and 250+ products
You can only see the accounts that come to you
Your TAM is visible to you only when accounts engage with your content. The rest - the majority - are invisible until it's too late.
Category-wide TAM visibility is impossible
You can only see accounts that engage with your content - not the full market. Most in-market buyers never visit your site before choosing a vendor.
Competitor renewal cycles are invisible
You have no signal when a competitor's customer enters renewal mode. By the time they reach out to you, they've already renewed - or they're about to.
Displacement campaigns are broad and untargeted
Without signal on which competitor accounts are actually ready to move, displacement outreach hits the full installed base - and conversion rates show it.
Full category visibility. Precise displacement timing.

MarketSizer for SaaS vendors - frequently asked questions
How does MarketSizer help SaaS vendors?
MarketSizer maps the entire buying landscape for your software category - who is in-market, who is renewing, and who is unhappy with the incumbent. Instead of only seeing accounts that engage with your content, your team gets visibility into every active evaluation, renewal, and displacement opportunity in your category.
How is this different from running ABM against the installed base?
Broad displacement campaigns hit the full installed base because there is no signal on which competitor accounts are actually ready to move. MarketSizer ranks competitor accounts by switching propensity, renewal proximity, and live intent signals - so outreach reaches the right accounts at exactly the right moment.
How much of the category does MarketSizer cover?
MarketSizer tracks 200+ vendors across 250+ products with 5 years of renewal cycle history and 2.5M+ active evaluations across all categories. The Category Map shows which accounts use which products, when contracts likely renew, and which segments are showing switching propensity.
Can we re-engage former customers when they return to market?
Yes. Winback Opportunities surfaces former customers the moment they return to the market, ranked by ACV potential and win likelihood. Combined with daily competitive signal refresh, your team is alerted when a churned account starts evaluating again instead of finding out after a competitor wins the deal.
