Frequently asked questions
What's included in the free plan?
The free plan lets you browse company profiles, view their full technology stacks, and filter by industry, location, and company size. Contact emails are partially masked (e.g. j***@company.com) and you're limited to 10 pages of search results. CSV exports are not available on the free plan.
What kind of contacts do you provide?
We provide decision-maker contacts including CEOs, Founders, CTOs, VP of Engineering, Head of Sales, and other key executives. Each contact includes their name, title, verified email address, and LinkedIn profile URL.
Can I cancel anytime?
Yes. Both monthly and annual plans can be cancelled anytime from your dashboard. You'll retain access until the end of your billing period. No annual contracts, no cancellation fees.
How often is the data updated?
Our company database is updated regularly. We continuously scan websites for technology changes and verify contact information to ensure accuracy.
How many companies can I export?
Pro subscribers can export unlimited companies to CSV. Each export can include up to 5,000 companies with their full tech stacks, contact details, and company information. There are no daily or monthly limits.
How is StackWho different from BuiltWith?
While BuiltWith focuses purely on technology detection, StackWho combines tech stack data with verified decision-maker contacts. This means you can find companies using specific technologies AND immediately reach out to the right people -- CTOs, VPs of Engineering, Heads of Sales, and other key decision makers. No more hunting for contact info after finding your target companies.
