Start with a stable front end such as Webflow or Bubble, a flexible database layer like Airtable or Notion, and robust automators like Zapier, Make, or n8n. Add analytics with PostHog or Mixpanel, and optional routing through Segment. Evaluate pricing tiers, rate limits, and governance features early. Standardize naming conventions, folder structures, and environment variables. Picking reliable building blocks now prevents later rework and keeps experiments fast, cheap, and measurable.
Define consistent event names, properties, and identities that span website, product, and CRM. Track essentials like Signed Up, Onboarded, Activated, Invited Teammate, Converted, and Churned. Use source, medium, campaign, and content parameters to preserve attribution. Build a simple users table and a unified user_id. Document everything in a living spec, ensuring experiments read the same vocabulary. With clean events, you can trigger precise journeys, run trustworthy tests, and diagnose wins or leaks immediately.
