Our story

Who founded Dux-Soup?
‍
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 the time-consuming part for him; and he could get on with building relationships and winning business.
‍
That idea is now used by hundreds of thousands of individuals, teams and agencies worldwide to automate their LinkedIn outreach and grow pipelines.

Who's behind Dux-Soup today?
‍
Our commitment to building LinkedIn automation that customers can rely on is unwavering. Many of the team have been here since the beginning, which means genuine continuity for customers. The people who understand your account history and your setup today are the same people who’ll be here next year, and the year after.

The core team came from around the world to celebrate our tenth birthday.

Why does your automation only work with LinkedIn?

People often ask why we focus on LinkedIn. We believe a specialist LinkedIn product delivers better results.

We concentrate on understanding the nuances of LinkedIn, how it changes, how people use it and how to help customers automate outreach safely and effectively. Rather than spreading our efforts across multiple channels, we’ve invested in making LinkedIn automation the best it can be.

Integrate-first policy

Need it in your CRM, AI assistant or existing tech stack? We connect to your existing tools via integrations.

We react faster when LinkedIn changes

LinkedIn updates its platform regularly, and every automation tool must adapt. The more focused a product is, the less there is to break, and the faster we can fix it.

Got a question?

Is Stacked powered by Dux-Soup safe to use on LinkedIn?

Yes. Stacked powered by Dux‑Soup has zero known account bans in 11 years of operation. Customers have sent 55 million+ messages and InMails safely in the last five years alone. Safety is built by default into how the product manages your activity.

How long has Dux‑Soup been around?

Dux‑Soup was founded in the Netherlands in 2015 by Will van der Sanden, making it one of the longest‑running LinkedIn automation tools on the market.

What makes Dux‑Soup different from other LinkedIn automation tools?

Stacked powered by Dux-Soup only works with LinkedIn. We haven’t tried to add on email, AI calling or other channels. Depth of focus, rather than breadth of features, is the whole strategy, and it’s paired with integrations into tools like ChatGPT, Claude, and CRMs rather than duplicating their functionality.

Does Dux‑Soup work with other tools like ChatGPT or Claude?

Yes. Dux‑Soup integrates with ChatGPT and Claude via its MCP Server, along with CRMs and collaboration tools such as Teams and Slack, so LinkedIn outreach fits into the workflows you already use.

How many people use Dux‑Soup?

ux‑Soup has 300,000+ users worldwide and is available in 9 languages.

Is Dux‑Soup still actively developed and supported?

Demand for LinkedIn outreach isn’t slowing down. Professionals in every industry including sales, marketing, recruitment, coaching, technology, professional services and more all rely on LinkedIn to reach the right people. As that demand has grown and evolved, so have we, without losing the focus that got us here. Scroll your LinkedIn feed for five minutes and you’ll see the promise: connect an AI, get 20 leads a day, no effort required. It sounds tempting right? But there’s usually no mention about keeping your account safe. Whereas we lead with safety and it underpins our customer service reputation.
