Context, not noise

Opportunity Score, ICP fit, and live subscription signals - on the page you are already on.

One score, everywhere

The same Opportunity Score your reps act on in MarketSizer, mirrored on every account they visit.

You switch tools every time you need account context

Prospects live on LinkedIn, in your CRM, and across a dozen outreach surfaces. The intelligence that helps you qualify them is locked inside MarketSizer, waiting for you to go and find it.

Your CRM shows contacts, not whether they are worth calling

HubSpot and Salesforce tell you who is in your pipeline. They do not tell you whether an account is actively evaluating, has a renewal coming up, or fits your ICP - so reps qualify by gut, not by data.

Intent data tells you who read an article, not who is buying

Generic intent platforms fire signals when a company browses a category page. MarketSizer detects real evaluation behaviour - active trials, subscription renewals, and buying-cycle signals that tell you when to move.

From any page to qualified account in seconds

Copilot overlays MarketSizer's account intelligence directly onto the pages your team already works on - no context-switching, no manual lookups, no stale exports.

Identify

Know instantly whether an account is worth your time

Open any website or LinkedIn profile and Copilot surfaces the account's Opportunity Score, ICP fit, and subscription status as a sidebar - no searches, no tab-switching, no manual lookups.

  • Works on any website, LinkedIn, HubSpot, Salesforce, Zoho CRM, Freshworks, Apollo, Lemlist, and Clay
  • Opportunity Score and ICP fit surfaced at a glance
  • Subscription status, active trial detection, and renewal signals in one view

Unlock

Go deeper without leaving the page

One click connects you to the full MarketSizer account view - historical subscription data, ACV estimates, and win likelihood - so you build context before you call, not after.

  • Linked directly to the MarketSizer web app for deeper discovery
  • ACV estimates and win likelihood without opening another tab
  • Historical subscription data and deal context surfaced automatically

Act

Prioritise and start credible conversations, in context

Copilot gives your reps the signal they need to decide who to contact first and what to say - informed by real subscription and evaluation data, not category intent noise.

  • Prioritise outreach based on live Opportunity Score and subscription signals
  • Save opportunity to your CRM without leaving the page
  • Start credible first conversations with context your prospects will not expect
Copilot action panel

Same intelligence, every surface your reps already open

Copilot does not ask your team to change how they prospect. It rides on top of the pages they live in - so the moment they need account context, it is already there.

On LinkedIn

Qualify what reps see, not what reps guess

Open any LinkedIn company page or Sales Navigator account and Copilot surfaces the Opportunity Score, ICP fit, and live subscription signals as a sidebar - no copy-paste into another tool.

Inside your CRM

HubSpot, Salesforce, Zoho, Freshworks

Copilot enriches the account record you are looking at with MarketSizer intelligence - evaluation status, renewal timing, ACV estimate - without leaving the CRM tab.

Across the web

Apollo, Lemlist, Clay, or any company site

If your reps work on it, Copilot works on it. Anywhere a company can be resolved from the page, Copilot shows whether the account is worth the next 10 minutes.

For team leads

Coach reps with the same signal

Managers see exactly what their reps see. Coach in context, defend pipeline reviews with the live Opportunity Score, and align on the same definition of a qualified account.

Every account Copilot surfaces carries the same Opportunity Score your team already acts on

Copilot does not surface raw data - it shows the composite Opportunity Score combining ICP fit, purchase intent, and win likelihood. The same number your reps use in the platform, now visible on every account you visit.

Questions about Copilot

Everything teams ask before rolling Copilot out to their reps.

Copilot reads the public URL and basic page metadata of the LinkedIn profile, CRM record, or company website you are viewing - just enough to identify the account. It does not scrape inbox content, attachments, or contact PII. The MarketSizer intelligence it surfaces (Opportunity Score, ICP fit, subscription signals) is fetched from your MarketSizer workspace, not assembled from your browsing.

Your market is mapped.
Your opportunities are waiting.

15 minutes. No commitment. We'll show you the accounts in your market that are actively evaluating right now.
