Before seeking major funding, Elysian validated its radical aircraft design with skeptical professors from TU Delft and MIT. Winning over these experts provided the critical credibility and third-party proof needed to build investor confidence in their unproven deep-tech concept.

The next wave of space companies is moving away from the vertically integrated "SpaceX model" where everything is built in-house. Instead, a new ecosystem is emerging where companies specialize in specific parts of the stack, such as satellite buses or ground stations. This unbundling creates efficiency and lowers barriers to entry for new players.

Instead of building a consumer brand from scratch, a technologically innovative but unknown company can license its core tech to an established player. This go-to-market strategy leverages the partner's brand equity and distribution to reach customers faster and validate the technology without massive marketing spend.

Startups often fail by making a slightly better version of an incumbent's product. This is a losing strategy because the incumbent can easily adapt. The key is to build something so fundamentally different in structure that competitors have a very hard time copying it, ensuring a durable advantage.

By coining the term 'low altitude economy,' China is signaling a deliberate, top-down industrial strategy to own the market for autonomous flying vehicles (EVTOLs) and delivery drones. This isn't just about a single company; it's about creating and regulating a new economic sector to establish a global manufacturing and operational lead.

Elysian Aircraft's strategy targets regions like the U.S. and Nordic countries where building high-speed rail is infeasible. By leveraging hundreds of existing, underutilized airports, they can create new, efficient short-haul routes, representing a path of least resistance for new transport infrastructure.

While consumer fintech gets the hype, the most systematically important opportunities lie in building 'utility services' that connect existing institutions. These complex, non-sexy infrastructure plays—like deposit networks—enable the entire ecosystem to function more efficiently, creating a deep moat by becoming critical financial market plumbing.

Unlike SaaS startups focused on finding product-market fit (market risk), deep tech ventures tackle immense technical challenges. If they succeed, they enter massive, pre-existing trillion-dollar markets like energy or shipping where demand is virtually guaranteed, eliminating market risk entirely.

Creating a basic AI coding tool is easy. The defensible moat comes from building a vertically integrated platform with its own backend infrastructure like databases, user management, and integrations. This is extremely difficult for competitors to replicate, especially if they rely on third-party services like Superbase.
