ProofEcho is built by one person who cares about trust.
I am M. Robi. ProofEcho is the product I am building full-time because trust is the thing I value most when I am picking a brand or about to buy something.

Why I built ProofEcho
Before I buy anything online I open three tabs. The product page, the pricing page, and the reviews. The reviews are the tab I spend the most time on. If a brand cannot point me at real customers saying real things, I close the window.
When I started shipping my own work, I realised most teams have great customers and zero way to show it. The praise was sitting in inboxes and Slack threads while the website read like a brochure. ProofEcho exists to close that gap. Collect the proof your customers already give you. Show it on the page where new buyers are deciding.
Who I am
I am a freelance web developer based in Indonesia, working with clients worldwide. Over the last 4+ years I have shipped 20+ custom websites for 10+ clients, with a focus on fast load times, strong SEO, and high-converting design. ProofEcho is the first product I am building in public, not for a client.
