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.

A hybrid evergreen fundraising model, combining periodic standard funds with continuous managed accounts, eliminates fundraising cliffs. This allows a firm to deploy capital counter-cyclically, buying when assets are on sale, rather than being forced to deploy or liquidate based on an artificial timeline.

Mega-funds can justify paying "stupid prices" at the seed stage because they aren't underwriting a seed-stage return. Instead, they are buying an option on the next, much larger round where they'll deploy real capital. This allows them to outbid smaller funds who need to generate returns from the initial investment itself.

To source proprietary hybrid capital deals, avoid the capital markets teams at PE firms, as their job is to minimize cost of capital. Instead, build relationships directly with individual deal partners in specific industries. This allows you to become a trusted, go-to provider for complex, time-sensitive situations where speed and certainty are valued over price.

For startups experiencing hyper-growth, the optimal strategy is to raise capital aggressively and frequently—even multiple times a year—regardless of current cash reserves. This builds a war chest, solidifies a high valuation based on momentum, and effectively starves less explosive competitors of investor attention and capital.

Raising venture capital is often a network-driven game. If you don't already have a network of VCs or a clear path through an accelerator, your focus should not be on fundraising. Instead, dedicate your effort to building a product people want and gaining traction. VCs will find you once you have something compelling to show.

SoftBank selling its NVIDIA stake to fund OpenAI's data centers shows that the cost of AI infrastructure exceeds any single funding source. To pay for it, companies are creating a "Barbenheimer" mix of financing: selling public stock, raising private venture capital, securing government backing, and issuing long-term corporate debt.

Moving from a science-focused research phase to building physical technology demonstrators is critical. The sooner a deep tech company does this, the faster it uncovers new real-world challenges, creates tangible proof for investors and customers, and fosters a culture of building, not just researching.
