35k orders per month .. charge $1 per order and you have a nice business. If you couldn’t figure this out on your own, then yes just shut down.
Focus on positive things.
Whats the current income ?
Why do you think you need to be funded ?
300+ active sellers sounds like great achievement!
Kudos
Where are you incorporated? How much cash are you looking for? How long a runway would that give you?
Are you charging for the product yet? If not, why not? Free is easy! But if people are using it they may well be willing to pay for it.
Would it work to continue to work on it while having a normal job?
Sounds like it may be too early to give up by you have to figure out what level you need to reach to be profitable and how much $ you need to get there.
Hey, I can help you. Please contact me via the email in my bio. Thanks.
Since you said you aren't currently charging anything for it, I would say you should wait to see if the market will validate it before shutting down. I.e, see if you can raise the price to something > $0 before calling it quits.
