This started off as a Kickstarter fundraiser:
backerkit.com/projects/zwim/zwim-smart-swimming-goggles
Than they closed that fundraiser and shifted over to Indiegogo:
indiegogo.com/projects/zwim-heads-up-display-for-swim#/
I ended up ponying up seed money to this company in 2017. They were promising delivery by May of 2018. I've heard nothing from the company and it's already July. They don't asnwer emails or messages on their FAcebook page. So at this point I'm assuming they closed down and took off with my money ($208.00) and the cash of 99 other backers.
These are the principals in the company:
Taegoo Kang - CEO
Seongryul Hong
Kiho Kim - Marketing
Sungju Ryu
Seungun Jung
Sewoong Kim - Production Managing
Zwim should at least have the integrity to post an open letter to all backers as to what is going on.
