Detailed Review
Dux-Soup is a LinkedIn-only tool. Its own site says it deliberately does not add email or calling and relies on integrations instead, and that it was founded in the Netherlands in 2015 by Will van der Sanden. The product is now sold as STACKED powered by Dux-Soup.
The contracting party is Supertec B.V., registered with the Dutch Chamber of Commerce (KvK) under number 64816931, with Dutch law governing the terms. The vendor's GDPR statement says service data is hosted on servers in the European Union.
Local or cloud, same campaign model
STACKED local runs as a desktop installer on your own Mac or Windows machine, while STACKED cloud runs on the vendor's infrastructure and keeps campaigns going without a computer switched on. The pricing page lists the same campaign features for both, and adds tap-and-go access and continuous running to the cloud version.
A campaign can chain up to 12 actions, including visit, connect, message, InMail, follow, endorse and like a post, with customisable delays between steps, drag-and-drop steps and automatic pausing when a response is detected.
Lead management and integrations
The tool tags and searches profiles, shows campaign statistics, tracks prospects through funnel stages and exports lead lists to CSV or third-party software. Native integrations listed on the pricing page include Slack, Salesforce, Pipedrive, HubSpot, SharpSpring, Freshsales and HighLevel, plus Zapier and Make.
The vendor states that it is compatible with LinkedIn, Sales Navigator and Recruiter, and that an MCP server connects the tool to AI assistants such as ChatGPT and Claude.
Where it stops
There is no email step, so a prospect who ignores LinkedIn cannot be followed up elsewhere inside the tool. The workaround is to push leads to a CRM or sequencing tool through the integrations, or to pick a multichannel tool such as La Growth Machine or Lemlist instead.
Limitations to Consider
Dux-Soup only covers LinkedIn, with no email sequencing or contact finder of its own, so many teams will pair it with another tool. Prices are in US dollars, and the local version depends on your own computer. Like every tool of this type it acts through your LinkedIn account, and LinkedIn's User Agreement prohibits bots and other unauthorized automated methods, a risk the vendor's safety claims cannot remove.
Who Should Use Dux-Soup
Freelancers, recruiters and small sales teams that prospect only on LinkedIn, want a Dutch contracting entity with EU-hosted data and are happy to connect their own CRM.
