Excellent social media workshop with Shannon and Finbarr. The team were super professional and friendly and we got a lot out of the session. Will absolutely use their tips and planning methods going forward and would love to do some more training in the near future.

Castle is a professional and knowledgeable company that has helped us so much- they’ve increased our overall outreach, assisted with the creation of polished, effective branding and documents, crafted quality content, and are very SM savvy. I would highly recommend to anyone but especially web3 companies. Castle has an in depth understanding of an industry still considered quite niche.
