Our Mission

Mental health help shouldn't be a luxury

Bangladesh has fewer than 300 psychiatrists for 170 million people — a 92.3% treatment gap. Millions experience panic attacks and anxiety with no tools, no language, and no support.

"I needed to talk to someone but couldn't find the words. That's what Decel is for — always."

Decel exists to close that gap. Every feature in Bengali and English, with South Asian cultural context at the centre of every decision. And completely free.

🌏

Built for South Asia

Designed for Bangladesh — Bengali & English, South Asian cultural context in every interaction.

💚

No judgment. No medical advice. Just calm, warm support when you need it most.
