What makes Claudiu’s story so remarkable isn’t just the tech, though that’s impressive, but the journey. He built the first version of Sentrya in under a month while working as an Uber driver, launched it on Product Hunt, and grew to over 450 users in 25+ countries using organic Reddit marketing alone.
Sentrya flips the traditional spam filter model: instead of trying to detect spam, it creates a clean list of approved senders and deletes everything else by default. This privacy-first approach has blocked over 200,000 scam emails so far, and it’s just the beginning.
We break down the conversation into three core parts:
- The Business & Business Model: How Sentrya works, its current traction, and Claudiu’s vision to compete with Gmail and Outlook by building a fully encrypted email service.
- Challenges of Scaling Up: From bootstrapping to a viral setback when an influencer falsely accused the platform of being a scam, Claudiu shares how he overcame it.
- Quickfire Questions: Insight into Claudiu’s mindset, strategies, and how his psychology background shapes his approach to building a tech startup.
💡 The one key thing:
You don’t need massive funding to build something impactful, clarity of purpose and strategic simplicity can take you far.
