The best platform depends on your goals and the size of your group. For interactive sessions with small to medium groups, tools like Hopin or Butter work well: clear, interactive and accessible. For larger livestreams with a professional look, streaming solutions like vMix or OBS are more effective.
For a fully branded experience, a bespoke studio setup is the strongest choice. The platform is a means, not the end. Live Impact advises based on your situation and handles the full technical direction.
