Yes, Tezos does have Tez.Capital behind it. Tez.Capital is a venture capital firm that specializes in investing and supporting projects built on the Tezos blockchain. As part of their mission to promote the growth of the Tezos ecosystem, they have launched a number of RPC nodes that are available for use. If you need an RPC node to use, feel free to DM me and I'll be happy to send you some operated by Tez.Capital. This will give you access to a reliable and secure connection to the Tezos blockchain, allowing you to interact with the network and build projects on top of it.
