✨What's wrong with the status quo?✨

Your GTM isn't broken, your timing is. And the cost of waiting is too high.

Signal Blindness

Your tools are full of signals, but without a shared timing layer, GTM teams can’t prioritise or act when it matters.

Bad Timing

You're sending outreach too soon or too late. Without real-time customer lifecycle signals, your timing advantage disappears and pipeline suffers.

Siloed Teams

Sales, Marketing, and Customer Success work in different tools, missing high-intent accounts. Without shared GTM signals, there’s no alignment or coordinated action.

Activity ≠ Intent

Your team is working hard, but not on the right signals. Without evidence-based buyer signals, you’re always guessing.

✨ MarketSizer Use Cases✨

Focus on the accounts that are ready to buy.

Not every “good fit” account is actually in-market. MarketSizer helps marketers spot buying signals so you can stop wasting budget on accounts that were never going to convert.

The best message won’t work if the timing’s off. We help you put real-time buying signals in your CRM, so you can prioritise accounts when they're actually ready to talk, not just when your cadence tells you to.

Keep the customers at risk. Grow the ones ready to buy.

You shouldn’t need a gut feeling (or a QBR) to know when customers are at risk or ready to expand. MarketSizer gives CS teams live signals so they can act early, not react late.
