What this comparison covers
Scale Intelligence maps your market from more than 75 sources, including Reddit, GitHub, job boards and filings, and offers engineers who build and run the system for you. Postelix maps your market on LinkedIn, watches who reacts to your company there, and is run by your own marketing team. This page is about the GTM company at scaleintelligence.dev.
The two tell a similar story. They differ in where they look and in how much of the work you do yourself.

What Scale Intelligence provides
Scale Intelligence describes its product as a digital twin of your whole market. Market Signals watches more than 75 sources: job boards, public filings, LinkedIn, Reddit, GitHub, events, review sites, rivals' pages and your own CRM and site data. Each signal comes back dated, with its source, and is linked to the person, the account and the rival it touches. Buyer Intelligence scores those signals per account and per person and routes the strongest buyers as leads, into Slack or a CRM.
You can run it yourself through its MCP connector, which its FAQ calls a beta, or have its engineers run it. Its site says self-serve plans are billed monthly and run on credits. Managed work includes a 90-day GTM Engine sprint and a fractional GTM engineer. For the engineer, a fee covers running it and Scale Intelligence also earns on the qualified meetings it books. See scaleintelligence.dev for the current offer.
What Postelix provides
Postelix is built around LinkedIn. It builds your market by name from LinkedIn and decides who at each account owns the problem. Then it watches what happens around your company: reactions and comments on your posts and your colleagues' posts, profile visits on connected accounts, company page visits and reactions to competitors' posts.
What it finds goes to Slack and HubSpot together with the colleague who already knows the buyer, and where that colleague allows it, the first message goes out from their account. People who are not ready yet get a nurture topic in your email tool.
Postelix is software your marketing team runs. The prices are on the website and you start with 7 days on your own market.
Oliver Trace, founder at 2050Max, on our homepage: "We went from broad lists and rough edges to knowing who's in our market and watching conversion follow."
Compare the workflows
Which fits your team?
Choose Scale Intelligence when your buyers talk in places outside LinkedIn, such as Reddit or GitHub, where developers and technical buyers spend their time. It also fits when you want someone else to build and run the outbound system: its fractional GTM engineer is paid a fee plus earnings on qualified meetings.
Choose Postelix when your buyers are on LinkedIn and marketing owns the program. You get software with a published price that your own team runs.
Where each one stops
Scale Intelligence covers a lot of ground, and much of the offer is a service. Its FAQ says self-serve is in beta, so ask which parts you can run yourself today.
Postelix is built around LinkedIn. It does not read Reddit, GitHub or review sites. If your buyers are quiet on LinkedIn, the capture side has little to read and the market map is the main thing you get.
Compare scope and cost
Scale Intelligence's pricing page says "Pricing is private for now." Its site says self-serve plans are billed monthly and run on credits, and that managed builds are scoped on a call. The fractional GTM engineer combines a running fee with earnings on qualified meetings, and places are by application.
Postelix Basic is EUR 490 a month for one market: 6,000 people kept current, up to 2,000 new people a month, every colleague's posts monitored and profile visits on 5 connected accounts. Team is EUR 1,190 a month for 3 markets and 18,000 people. Enterprise starts at EUR 3,900 a month. Prices exclude VAT. You start with a demo and 7 days on your own market, with a work email and no card.
Start from where your buyers talk
List the last ten deals you won and note where each buyer first showed interest. If most of them reacted to a LinkedIn post or looked at a colleague's profile, start with Postelix. If they asked a question on Reddit or opened an issue on GitHub, LinkedIn is the wrong place to look.

Questions
For LinkedIn, yes. Both map a market and route named buyers with a reason. Scale Intelligence reads many more sources and sells managed work. Postelix also sees who visits your colleagues' profiles and your company page, and where the colleague allows it, sends the first message from the colleague who knows the buyer.
No. Postelix reads LinkedIn closely, plus company news, hiring, public filings and website visits at company level. It does not read Reddit, GitHub or review sites. If that is where your buyers talk, Scale Intelligence covers it.
Scale Intelligence, if you buy the managed service, because its engineers run it. With Postelix you start from a list or your website and the results arrive in Slack.
In Postelix, each colleague chooses automatic or approval first and can switch it off at any time. Scale Intelligence's FAQ says you approve every message before it is sent.
