### Should You List on All Three Platforms?
Listing your startup on multiple platforms can increase your exposure to a wider range of investors. However, it’s important to manage this effectively:

1. **Consistency**: Ensure your information and pitch are consistent across all platforms.
2. **Time Management**: Managing multiple profiles can be time-consuming. Make sure you can effectively engage with potential investors on each platform.
3. **Platform Guidelines**: Check each platform’s guidelines and rules to ensure there are no conflicts with cross-listing.

### Recommendation
Given the current landscape and the unique strengths of each platform:
- **AngelList** is great for broad exposure and access to a wide network.
- **FundersClub** is excellent for curated support and a more selective investor base.
- **Gust** offers robust tools for managing investor relations and global reach.

If resources allow, listing on multiple platforms can be beneficial. However, if you need to prioritize, consider where your startup aligns best with the platform’s strengths and where you believe you’ll find the most engaged and relevant investor base. For many startups, starting with AngelList due to its broad network and additional tools, then expanding to FundersClub or Gust if needed, can be an effective strategy.
