Indonesia throws away 23 million tonnes of food per year. Jago Hemat ("Expert at Saving") is the two-sided marketplace solving it — connecting Jakarta restaurants with end-of-day surplus to 8 million price-conscious daily diners. Built and soft-launched in 18 days.

The Problem

Nobody Had Solved Supply

Every food waste app that tried in Southeast Asia failed because they optimized for users first. Beautiful consumer apps, launched to empty restaurants, watched users churn in week two. Supply creates demand in food — and nobody had cracked supply.

In Jakarta specifically, 8.2 million people eat outside daily. Bakeries overproduce by 15–20% every afternoon. Cafés have consistent end-of-service surplus windows. The food is perfectly fine. The window to sell it just closes at 9 PM.

The incumbent global player — Too Good To Go — charges merchants 20–30% commission and has no SE Asia presence. The local competition has dated UX and no legal compliance path. The market was wide open.

The Solution

Meet Merchants on WhatsApp

Jago Hemat doesn't make merchants download an app. It meets them on WhatsApp — the platform they already live on — with a magic link that gets them listing surplus in under 60 seconds.

  • Merchants list surplus via WhatsApp or web dashboard — no download required
  • Users browse nearby bags, order, and pay through the Jago Hemat mobile app
  • Users pick up in-store — food's still warm, price is 50–80% below menu
  • 0% commission Year 1 (beat TGTG's 20–30%), flips to 10% Year 2, 15% Year 3
  • ESG reporting product monetized separately from Year 3

Mobile Apps

Live on Play Store
& App Store

Native Android and iOS apps delivering the full user experience — browse nearby surplus bags, order in seconds, pay via GoPay/OVO/Dana, and pick up while food is still warm.

📱 iOS App
Available on the App Store — browse, order, pay, and collect surplus bags from Jakarta's best restos.
🤖 Android App
Live on Google Play Store — same experience, optimized for the 130M+ Android users in Indonesia.
💳 Local Payment Rails

Technical Architecture

Built for Jakarta's
Infrastructure Realities

Unreliable desktop adoption. WhatsApp dominance. Payment rails that require Dana/OVO/GoPay — not cards. This is what the stack was designed around.
