MarketSizer
A sales-intelligence platform that helps B2B software teams prioritise accounts using subscription trials, renewal windows and competitor-switching signals.

01 / The product
What it is trying to do.
MarketSizer presents account-level signals intended to help software vendors decide which potential or existing customers deserve attention. Its current platform combines fit, buying-intent and opportunity indicators with information about trials, renewals and competitor changes. Teams can filter opportunities and move information into sales systems such as HubSpot, Salesforce and Pipedrive. The service offers account creation, sample data and demonstrations. Its own timeline records a 2026 platform launch following earlier work on a market-sizing tool and a Chrome prototype. The company describes a small remote-first team founded in Dublin. Its current hiring FAQ explicitly says it is not actively recruiting.
Who it is for
B2B software sales, marketing, account-management and revenue-operations teams.
The problem addressed
