There is a project whose fundraising model is worth examining. Their launchpad design is truly unusual — investors' funds are not directly handed over to the team for reckless spending, but instead employ a more cautious locking mechanism. Specifically, the raised funds can only be used for marketing, which greatly reduces the risk of funds being diverted for other purposes. What's more interesting is that if the project team changes the roadmap or breaks their promise, investors can receive a 100% refund of their funds. This mechanism links fund security with the credibility of the project team, making it a design approach worth learning from.
