What this comparison covers
Teams look for a 6sense alternative when the contract is too large for the team, or when the score names an in-market account and nobody knows whom to contact there. 6sense ranks accounts by research activity across the web and runs ads to the ones warming up. Postelix names the right person at each of your accounts and shows who has already reacted to your company on LinkedIn, with the colleague who knows them.
A team with a known list of accounts can run Postelix without 6sense. A team that keeps 6sense can add Postelix for the people at the accounts it flags.

What 6sense provides
6sense describes itself as intelligence for agentic GTM. Its Signalverse collects intent, company and contact data, and its pages cite keyword-level intent, predictive in-market scores trained on your own data, and website deanonymization that matches anonymous visitors to accounts. Revenue Marketing identifies the buying group at each account and runs advertising across display, social and connected TV.
A separate product, Sales Intelligence, gives reps company and contact data with credits for emails and phone numbers, and has a free way to start. See 6sense.com for the current packages.
What Postelix provides
For each account, Postelix reads the people inside and names who owns the problem and who else sits on the buying committee. Job titles are a weak guide here, because the same role carries a different title at every company.
It then shows which of those people reacted to your posts, visited a colleague's profile or engaged with a competitor, and attaches the post or the visit. Where the colleague allows it, the first message goes out from the account of a colleague already connected to the buyer, automatically or after they approve it.
Postelix buys no intent data and has no predictive account score. It works from what a named person did on LinkedIn, plus company news, hiring and company-level website visits.
Schulaxshan Arulampalam, founder at random-assistant, on our homepage: "The competitor-engagement view alone makes Postelix worth it. Seeing named people move between us and our competitors weekly is a real step forward for demand gen."
Compare the workflows
6sense or Postelix for a small team
Choose 6sense when you have thousands of accounts and need to know which few hundred to spend on this quarter. It is a large platform, and it pays off when a team has the people to run it.
Choose Postelix when you already know the accounts and the gap is the people. It also fits a market of a few hundred people, where an intent model has little to rank. If you are also looking at Demandbase, see Postelix vs Demandbase.
Where each one stops
6sense works from the account down. Its intent signal is matched to a company, and the people come from contact data and buying group models.
Postelix reads public LinkedIn activity, company news and hiring, company-level website visits and your own CRM data. It does not score accounts on research across the web, so a buyer who researches quietly and never reacts in public does not show up by name.

Look at one in-market account
Open an account your intent platform flags this week. Write down who you would contact and why that person. Then check whether anyone on your team is connected to them. If that takes more than a few minutes per account, that is the work Postelix does.
See how Postelix finds the right person, how it captures the people who engage, who engages with your competitors and what it measures.
Questions
For a team that already knows its accounts, yes. Postelix names the people at each account and catches the ones who engage with you on LinkedIn. It does not score accounts on research across the web, so a team with thousands of accounts to rank may keep 6sense for that.
No. Bought intent data says a company researched a topic. Postelix shows which named person did what, and attaches the post or the profile visit.
Postelix adds the people at the accounts 6sense flags: who to talk to first, and which colleague already knows them.
Postelix shows which colleague is already connected to the right person at that account, and whose post or profile that person reacted to. Use that connection for a direct message or a warm introduction.
6sense does not publish prices for its marketing platform. Vendr reports a median of USD 62,220 a year across 386 purchases (read 14 October 2026). Postelix starts at EUR 490 a month on a monthly plan.
Yes. A small market is where knowing each person matters most. Skip the ads and start with the map and your leaders' posts.
Postelix writes only to people who fit your market and showed interest in your company, inside a low daily limit per account, paced the way a person works. No tool that acts on a LinkedIn account can promise zero risk, so each colleague chooses automatic or approval first and can switch it off at any time.
Book a demo. Then run it on your own market for 7 days.
The demo is with the founder and shows the loop in action. A work email is enough, no card.
