These do already exist and there are many of them already on both Ethereum and Binance Smart Contract networks. More will be coming with SORA/Polkadot and I suspect it won't be long before they are on Harmony, as well (basically any EVM compatible network will likely have these).

I'm not sure exactly on the terminology, but essentially most large DEXes (Decentralized Exchanges) will typically get involved in funding new coins. Typically what happens is a DEX will (either through governance of via the DEX developers) offer to "host" a new coin in their liquidity pools on the DEX, and boost that coin by incentivising users with additional rewards for proving liquidity (typically in the form of tokens for that given startup). These incentivised liquidity pools are called "farms" and launching a crypto startup in this way is typically called a "Initial Farm Offering" or "IFO".

There are also more projects on the horizon that aim to further this idea of providing liquidity to developers in exchange for coins.
