"This is necessary in a country where people have to rely on whatsapp statuses to find blood for emergencies. Apps a good idea with notifications and everything. Would this service be free to use by both hospitals/victims/donators? Or would one of…"

"Security is a must in order to prevent fraud and spam. Accident victim details would be important too otherwise in a country like India it's very possible for people to take advantage of this service and start scamming people in the name of blood"

"Extreme worst case scenario: how would this work if there is a very big accident involving dozens of people? Won't it get overrun with requests pinging the same person multiple times? You'll have to make it so there's a limit on the requests is…"

"Would the hospital or the service be paying for the transport costs for the donators? Or is just based on the good will of the donators?"

"This exact same service could be used by blood banks too, so we don't need to worry about people coming as soon as possible. Removing the emergency part completely. Which is a good thing"

"You would probably have to remove the district to city to state radius feature as feasibility wise noone would be willingly to go from one side of the state to the other side. Seems a bit unnecessary to be honest. Unnecessary feature. Everything…"

"According to red cross it should be 3 months not 2. You'll have to change that. You'll also have to figure out if u can send these requests to actual blood banks instead of just registered users"

"I recommend partnering up with local governments and state governments in order to get a proper list of registered blood donars because right now that might be the biggest problem"

"How would you start scaling the service? And what is the monetisation model? Would you be charging the hospitals or the donatees or the person who needs the blood? Charging the hospitals would make the most sense"

"Really nice idea, how would you both secure data and collect data such as blood groups, addresses, phone numbers in order to do this?"

"We'd probably start off with giving it to select hospitals in Hyderabad and giving access to blood donars to anyone who downloads the app (MVB it'll be an app) and from there we'll slowly scale."

"I see two problems with this. First is how will you make sure your app does not give both false positives and negatives.

Second is how will you prevent user data being leaked. Mental health can be very private and it getting leaked is a horrible…"

"How will you deal with false positives? Maybe giving you're absolute predictions as a percentage instead?"

"All games give seasonal updates to their games to keep things fresh. How will you be able to do this while still basing things off of real life?"

"LifeLine really nails a problem we’ve all seen, frantic WhatsApp forwards and no real way to know if help is coming. I like how it works like an Amber Alert for blood, cutting through the noise and reaching the right donors fast. The tricky part…"
