A group of Cardano enthusiasts and ambassadors providing content and offering consultations.
The Cardanians’ blog covers everything from news-style update posts about things happening in the ecosystem, to interviews with projects building on Cardano, to pieces explaining all facets of the Cardano blockchain and ecosystem. Many of these articles are long reads offering in-depth information and a bit of background knowledge is sometimes required.
In their "about me" section the Cardanians profess that they are business experts who do consultations. It would seem that they offer staking consultations but it is not 100% clear as they profess business expertise also.
