Presence & Market Position
Tracked · below panel floor — earned mentions are accruing toward the next scored window.
Measures earned, engagement-weighted share of voice across the GTM voices panel. Methodology →
Dux-Soup positions itself as a browser-extension automation layer for sales, recruiting, and agency teams that want outbound LinkedIn outreach running inside their own account rather than through a third-party access layer — automated connects, profile views, follows, and messages, extended lately with an AI feature for personalizing that outreach at scale. Its presence in the broader GTM conversation is early and quiet so far, more visible through direct product use than through active discussion in outbound and prospecting circles.

Business Profile
Dux-Soup launched in 2015, built by founder Will van der Sanden to automate the LinkedIn prospecting work he was doing by hand, and has stayed independent since, operated under Supertec BV with no outside funding on record. The company marked its tenth year in 2025 and has grown to roughly 300,000 users spanning recruitment, coaching, technology, and professional-services teams. It reports around $3M in ARR as of 2024, continuing as a founder-led, self-sustaining business with both cloud and desktop deployment options built out over the decade.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Dux-Soup's agent-facing surface is a webhook and remote-control API: LinkedIn visit, action, and message events flow out, and connection requests, profile visits, and messages can be triggered back in, available on its paid Turbo and Cloud plans. The company has also added an AI feature for personalizing outreach copy and lists integrations with tools including Claude, Gemini, and ChatGPT, though the API documentation itself does not yet describe direct agent or LLM orchestration.
