About
Dux-Soup builds LinkedIn automation software, now sold as STACKED, powered by Dux-Soup, for individuals, teams and agencies. STACKED runs multi-step drip campaigns of profile visits, connection requests, messages, InMails, endorsements, follows and post likes, and pauses a campaign when a prospect responds. It offers AI-powered message personalization, campaign statistics and lead management, with two-way integrations to CRMs such as HubSpot, Salesforce and Pipedrive and to ChatGPT, Claude and Gemini, including through an MCP server. The product runs either locally as a desktop app for Mac and Windows or in the cloud on Dux-Soup's infrastructure. Dux-Soup was founded in the Netherlands in 2015 by Will van der Sanden, is provided by Supertec BV, and the company says it has more than 300,000 users.
Dux-Soup’s Story
In 2015, Will van der Sanden was spending too much time manually finding, qualifying and following up with prospects on LinkedIn, so he built a LinkedIn automation product to do that work. Dux-Soup launched that year as a single-user tool, added a Zapier integration in 2019, multi-stage campaigns in 2020 and its first Team plan in 2021.
Cloud Dux, running on the company's own infrastructure, launched in 2023, and an Agency Dashboard for managing client accounts followed in 2024. In 2026 the company added Microsoft Teams, ChatGPT, Claude and Gemini integrations and an MCP server, and the product is now sold as STACKED, powered by Dux-Soup.
TopCloserR Perspective
What we’d expect selling here to look like
Dux-Soup sells per-seat STACKED subscriptions, billed monthly or yearly, to individual LinkedIn users, sales teams and agencies that manage client accounts. The offer implies a mostly self-serve purchase, with demos for teams and agencies and discounts for teams of 10 or more seats.
What it builds, by career stage
- Breaking in
- For SDRs, BDRs and those aiming for a first SDR role, the business implies following up on demo requests and trial users across sales, recruiting and agency segments, which builds fluency in LinkedIn prospecting.
- Building
- For account executives and those working toward that title, it implies selling team and agency dashboards, where the case rests on account safety controls, seat management and CRM and AI integrations.
- Leading
- For sales managers, directors and heads of sales, it implies leading a team that sells a LinkedIn-only product against multichannel tools, so positioning around focus and account safety carries the conversation.
Where it can take you
The experience transfers to sales roles at sales engagement, LinkedIn automation and lead generation software companies. It also suits roles selling to agencies and recruiting firms at other product-led SaaS companies.
