Automated ETH smart contract execution through a decentralized bot network. Quite unique and therefore interesting. They also have a decent intro video that explains what they do. But there's not a lot of info about their size.

You might never heard of it, but, if you are using DeFi you used GELATO for sure without noticing it.
Gelato is allowing devs to implement automated bots to their Dapp, those are essential to DeFi, they allow you to place and trigger a limit order on Pancake swap, auto compounding on Beefy Finance and more.
The main Gelato’s product is called “AUTOMATE”, it’s a market place of bots where devs can come, choose and pay for specific bots. Gelato is compatible to every EVM compatible chain.
Every Dapp in the ecosystem is using Gelato (see the picture below).
This is not a main stream protocol, it’s really a dev specific product and they have no competitor (as far as I know) wich is a really good point when you search a protocol to invest in. No Financial Advice
