M

Marcus D.

Founder, D2C Skincare Brand

★★★★★

"Found StackScan from a Reddit post and signed up the same day. I searched for graphic design blogs, then tried a few related keywords, and pulled lists with a relevance score on every result. Honestly one of the best lead lists I have built in years. The signal-to-noise ratio is amazing."

Sarah K.

B2B Growth Consultant

"Came across StackScan recently and decided to grab the lifetime deal without thinking twice. Best purchase I have made this year. I use it almost every day now for security research and tech lookups. The depth of detection is impressive for the price."

Andrei Vasiliev.

Independent Security Researcher

★★★★★

"We offer WordPress redesign services and go after agencies using Elementor or Divi. StackScan lets us filter by page builder so our outreach list is already pre-qualified. Way better than scraping directories manually."

J

Aleksandar Kuksov.

Director, WordPress Design Studio

★★★★★

"We focus on HubSpot users in Germany and Austria. StackScan is the only tool we found that lets us combine technology and country filters and export a clean list. It replaced a manual process that used to take our team a full day."

L

Lena B.

Sales Ops Lead, German SaaS Company

★★★★★

"We pitch website migrations and needed to find businesses still on Joomla or Magento. Built the prospect list in StackScan, sent a cold email sequence, and converted enough of them in the first month to cover the cost of the plan many times over."
