Don't let this gap widen
Without mastery of PlanetScale, 70% of startups suffer critical downtimes during scaling, resulting in customer losses estimated at 10 000€ per hour according to Gartner.
Your competitors using Vercel or Supabase capture 40% additional market share with resilient DBs, while your outages stall growth and increase infra costs by 300%.
As a freelancer or entrepreneur, you risk business failure: 25% of startup failures cite DB issues as the main cause.
Invest in this training to secure your infinite growth starting today.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
