You already know your ICP. What you don’t know is when they’re trialing a competitor, about to renew, or just churned until it’s too late.

Most tools show you clicks, job changes, or web visits. MarketSizer tracks live trial, churn, and renewal data, the true signals of intent.

Say a competitor is renewing. Should you engage? Only if your win rate with similar accounts is high. Without win probability, you're flying blind and misallocating your best reps.
The MarketSizer Chrome Extension works on any company website, LinkedIn, and prospecting tools like Apollo or Lemlist, revealing real-time subscription changes, competitor trials, and tech stack context inside the pages you already work in.
See real-time subscription signals on any website, LinkedIn, or Apollo, and push insights directly into your CRM. No disruption. Just action.
