Just stumbled upon this topic, I recently experimented with a bot like this (just for personal use so not commercially available at the moment). I think important to note is that all new listings are announced at least a few hours upfront, which also causes spike prices on Uniswap or other platforms, if the coin was available there already.

The bot has the launchtime and pair as input and just starts buying from the time it lists.

However to catch the initial spike before it hits Binance I created another bot which sends you an alert when there's a new listing announced. That's still a manual process though, because there are tons of exchanges out there where the coin could possible be listed before Binance, but made some good profits with this second one one already :-)
