01
Start with a narrow ideal customer profile
Do not begin by exporting thousands of domains. Choose one market and one problem your agency can genuinely solve, then use stack, category, country and launch timing as qualification inputs.
- New Shopify stores for conversion work.
- Recent Next.js or Webflow launches in industries you understand.
- Fresh local-business sites in a market you can actually serve.
02
Treat the data as context, not intent
A detected technology does not mean a company wants to replace it, and a recent launch does not prove budget or dissatisfaction. Review the live site for a visible business problem before outreach.
- Check mobile UX, analytics, metadata, conversion structure and message clarity.
- Remember StackScope records are launch-time observations and the stack may have changed.
- Score fit and visible opportunity separately from freshness.
03
Use watches and MCP after a filter proves useful
Once a filter consistently produces real opportunities, turn it into a Stackdar watch or API workflow. MCP can help explore and qualify candidate sets inside an assistant.
- Keep a human review step before adding prospects to a CRM.
- Do not automatically send messages simply because a domain matches a filter.
- Measure which filters produce replies, meetings and clients instead of optimizing for list size.
04
Make outreach specific and lawful
Good outreach explains an observed problem and a useful next step. StackScope itself says its data is not a mailing list, and its paid-data licence limits redistribution and corpus reconstruction.
- Use appropriate published business contact routes.
- Follow applicable privacy, anti-spam and platform rules.
- Treat StackScope as an early-signal layer, not an automatic sales machine.
