Warmly alternative for website visitor and LinkedIn signals
HubSpot agreed to acquire Warmly on June 30, 2026. Syft Data identifies the companies and, where it can, the people visiting your website, joins them to who engages with your team's LinkedIn posts, checks each one against your ICP and personas, and sends the ones who fit to Slack, Salesforce, HubSpot or your outbound tool.
Works with Salesforce and HubSpot, and is independent of both.

On top of website visitors
What Syft Data adds
See who engages with your team's LinkedIn posts
Reactions and comments on your company posts, exec posts and promoted posts, matched to one person and joined to their website visits.
See which target accounts saw your LinkedIn ads
Connect LinkedIn Ads and Syft shows which companies saw your ads, next to who from those companies engaged with your posts. Pro plan.
Focus on your target accounts
Add your target accounts, or connect a HubSpot list that Syft re-reads every hour. Alerts can then fire only for people at those companies, and a do-not-track list keeps customers and partners out.
Skip people you already know
Syft syncs your LinkedIn connections, leaves out people you are already connected to, and can flag when a lead is connected to someone on your team.
Know who signed up
Syft enriches product signups, including personal emails, and scores each one against your ICP and personas before it alerts sales.
Ask @Syft in Slack
Ask in plain English for a list, an explanation of a motion or a summary of the week, and get the answer in the channel.
Alerts only for people who fit
The usual complaint about signal tools is volume. Many of the people on your site or reacting to your posts are recruiters, students, job seekers or other vendors.
In Syft you describe the companies you sell to (your ICP) and the roles you sell to (your personas). Every visitor and engager is checked against both before anything reaches Slack or your CRM. Everyone else is still recorded, so you can look them up later.
Act on a match from your own account
Syft can send the connection request or the first DM from your LinkedIn, through the extension, using the note you wrote. By default each one waits for your approval in Slack or in the app. You set the daily limit.
If your team already sends from Smartlead or Instantly, send the matches there instead and keep your sequences.

Questions Warmly users ask
- What happens to Warmly after the HubSpot acquisition?

- Does Syft Data work with Salesforce?
- Yes. Syft Data syncs with Salesforce, HubSpot, Attio and Pipedrive, and creates or updates the contact and company when someone matches. It is independent of all four.
- Does Syft Data identify individual website visitors?
- Yes, where it can. The Syft tag identifies the companies visiting your site, and person-level identification of US visitors is an add-on. Syft joins each visitor to their LinkedIn activity, so a post engager who reads your pricing page shows up as one person.
- How long does setup take?
- Add the tag, then connect your CRM and Slack. Data appears about 10 minutes after the tag is live. We can set it up with you on a call.
- Can I keep using Clay, Smartlead or my other tools?
- Yes. Smartlead, Instantly and Apollo are native. Send matches to Clay, Zapier or n8n by webhook, so your sequences stay where they are.
- Is my LinkedIn account safe?
- Syft reads LinkedIn through a Chrome extension in your own browser, so there is no password to hand over and nothing logs in to your LinkedIn account from a server. It only sends requests or messages you approve, up to the daily limit you set.
- Does it work for a whole team?
- Yes, on Pro. Each person installs the extension, and Syft tracks everyone's posts, profiles and the accounts you watch in one workspace.
- How is Syft Data priced?
