There is no definitive answer to this question as there are a number of different factors to consider when choosing a platform for launching an international startup. Some of the factors you may want to consider include the following:
- The business model of your startup
- The target market for your product or service
- The amount of funding you have available
- The level of support you need from a platform provider
Some popular platforms for launching international startups include Kickstarter, Indiegogo, and AngelList. Each of these platforms has its own advantages and disadvantages, so it's important to do your research to see which one would be the best fit for your particular startup.
Another option to consider is working with a startup accelerator or incubator, which can provide you with the resources and support you need to get your business off the ground. Many of these programs have a global focus, so they can be a good option for launching an international startup.
