Is Instagram a good platform to build momentum ahead of launch?

Hey PH community 👋🏽 I’m contemplating a PH launch in the foreseeable future for an AI powered automation platform for social media that we’re developing and I’m researching launch best practices. We naturally have more reach on Instagram than other platforms and I’m wondering if someone has a good experience of using Instagram for a PH launch and if so how did they do it. Thanks for your help
