The MarketSizer Product

Qualify every opportunity.

MarketSizer shows SaaS vendors which accounts are actually in-market, fit their ICP, and are historically winnable so they focus effort where it matters.

GTM teams waste time on the wrong accounts.

Most sales and marketing efforts fail because teams can't answer three simple questions: Is this account a good fit? Are they in-market right now? Can we actually win this deal?

We show you qualified opportunities you can trust.

Every account MarketSizer surfaces is backed by evidence across three critical dimensions.
