Building Your Stack

1. Start with analytics: You can't optimize what you can't measure. Sellerboard first.
2. Add keyword research: Helium 10 gives you the data foundation for listing and PPC optimization.
3. Automate PPC: Once you're spending $5K+/month, AI bid management pays for itself immediately.
4. Layer in inventory AI: As your catalog grows past 15-20 SKUs, manual forecasting breaks down.
5. Add pricing automation: If you have competitor seller issues, AI repricing is essential.

That's the Kompound approach. Every action compounds.
