This got be curious. I guess we all have started/failed/sold products and businesses in the past. Let's start listing them here.

What businesses did you start/think of starting/left halfway/sold in the past?

Here's what I've done so far:

1. Voyed (2010) - Design & Development Service - Ran it for 6 months before shutting it down.

2. Grey Shade Design (2012) - Design blog - Ran it for a year. Didn't blog religiously so shut it down.

3. Odyssey (2014) - Solar System simulator for school students - Didn't monetize. Put it on GitHub as an open source software.

4. Dabbawala (2014) - Food delivery service levering the dabbawalas (food delivery people) of Mumbai - Built only a prototype to test it out. Didn't release into production.

5. Symposium (2015) - Hacker News for college students - Left it halfway. Didn't release.

6. Streakle (2015) - Peer review platform for amateur designers - Shut it down in 6 months. No traction.

7. Linkletter (2016) - Product Hunt meets Pocket - Ran it for 15 months. Failed to monetize. Shut it down.

8. FTW (2016) - Video only group messaging service - Built a prototype. Lost interest later. Didn't release.

9. Social Squint (2018) - Instagram automation tool - Started out for a business idea, but later didn't release it. Kept it only for personal use.
