The problem

Signal-based selling breaks at the last mile

Every GTM team talks about signal-based selling. Someone reacts to a competitor's post — that's intent. Someone registers for an industry event — that's interest. Someone comments on a topic you solve — that's an opening.

But what happens next? You screenshot the post. Open Sales Nav. Search each person manually. Copy to a spreadsheet. Find their email in another tool. Verify it in a third. By the time you send, the signal is 5 days old and they've forgotten what they reacted to.

Filtrat closes the gap between signal and send.

Signal capture

Capture signals with verified emails in real time

Posts

Paste URL. Get reactors with emails.

  • Every reactor and commenter captured
  • Verified email for each (catch-all resolved)
  • Reaction type, comment text included
  • Monitor for 7 days — new leads auto-append

Events

Full attendee list. Even if LinkedIn hides them.

  • Auto-registers to unlock the full list
  • Verified emails for each attendee
  • 7-day monitoring for late registrations
  • Stronger intent — they blocked their calendar

Content Search

Find posts by keyword. Capture the audience.

  • Search by topic, competitor name, pain point
  • Filter by date: 24h, week, month
  • Capture reactors from the top results
  • Find conversations you should be in

Why timing matters

Day 1 after a post, you're part of the conversation. Day 5, you're noise. The window between someone engaging with content in your category and them making a decision is short. Filtrat makes sure you're in their inbox while they're still thinking about it.

7-day monitoring

Set it once. Walk away. Leads auto-append as they engage.

Turn any post or event into a lead magnet that runs for 7 days. New reactors and attendees automatically append to your lead list with verified emails as they engage.

Use cases

Your competitor posts about their new feature — you capture everyone evaluating the category

An industry leader publishes a take on a trend you solve — their audience is your audience

Your own post gets traction — capture the engagement you're already generating

Company search

From company list to decision-makers with emails. One step.

Give filtrat a list of companies. Pick seniority and title. It searches every company, finds the right people, resolves domains, and returns verified emails. Sales Nav makes you do this one company at a time. Filtrat does it for the entire list.

Before filtrat

Open Sales Navigator, search company, filter by title

Click profile, copy name

Open finder, paste, wait, verify

Next company. Repeat 50 times.

With filtrat

Upload company list

Pick "VP, Director" + "Marketing, Sales"

Verified emails back for all companies

50 companies × 3 decision-makers = 150 verified leads. Time: minutes, not a morning.

MCP — for AI GTM stacks

Your AI agent runs the entire pipeline. Finding emails is just the start.

Everything on this page works through MCP. But the real power is what happens after filtrat finds the leads. Your Claude agent captures the signal, finds the email, and then keeps going — filter by ICP fit, draft personalized first lines, score leads, route to your sequencer.

What your agent can do in one conversation

“Monitor this competitor's post for 7 days, capture every reactor with a verified email, filter to VP and Director level only, and draft a personalized opening line for each based on their recent LinkedIn activity”

“Find all attendees of this event, get their emails, score them against my ICP criteria, and export only the ones that match”

“Search LinkedIn for posts about 'email verification' from the last 24 hours, capture the top 5 by engagement, get emails for all reactors, remove anyone under 500 connections, and group them by company size”

“From this company list, find decision-makers with emails, check their recent posts for buying signals, and draft a personalized outreach sequence for each”

What you're replacing

Lead scoring tools — Claude scores against your ICP for free

ICP filtering — Claude filters by any criteria in plain English
