Sourcery · Jun 14, 2026

1-3-7 Ventures' Justin Fischner-Wolffsen discusses backing SpaceX, pioneering the secondary market, and investing in category-defining companies.

Venture Investors Should Back Dominant Companies, Not Chase Hot Categories

The success of a category is often driven by one exceptional company. Instead of diversifying across a hot sector like 'space tech,' investors generate better returns by concentrating capital in the clear winner, like SpaceX, which captures a disproportionate share of the market value.

The JOBS Act Unlocked the Secondary Market by Removing the 500-Shareholder Cap

Before the JOBS Act, companies like Facebook were forced public by the 500-shareholder rule. Removing this constraint allowed successful companies to stay private longer. This extension of the private lifecycle created a massive need and opportunity for secondary liquidity for employees and early investors.

Focus on Absolute Cash-on-Cash Returns, Not Arbitrary Ownership Percentages

Many VCs fixate on hitting a specific ownership percentage, which can be a misleading heuristic. The ultimate goal is maximizing returns for LPs. It's better to own a smaller piece of a generationally massive company than a larger piece of a modest one if the exit potential is large enough.

Test Failures Are Valuable Learning Events If They Generate Actionable Data

In complex systems like rockets, failures during testing are not setbacks but essential parts of the development process. The key is whether the 'failure' produces data that leads to improvements. This 'launch and learn' ethos, pioneered by SpaceX, accelerates progress far faster than trying to predict every issue.

Facebook's Ban on Share Sales Created a Perverse Incentive for Top Talent to Quit

When Facebook was private, it tried to stop employees from selling shares by threatening to fire them. This backfired completely. Employees who wanted liquidity were forced to quit to become 'former employees' who could then sell their shares, creating an entirely avoidable talent drain.

Entrepreneurs Need Just Enough Knowledge to Act, Not So Much They're Paralyzed

Starting a venture requires a delicate balance of knowledge. An entrepreneur must know enough to identify a real opportunity and have a credible chance of success. However, knowing too much about all the potential obstacles and challenges can lead to analysis paralysis and prevent them from ever starting.

SpaceX's Dominance Came from Business Model Innovation, Not Just Technology

While reusable rockets were a technological marvel, SpaceX's equally crucial innovation was shifting the aerospace industry's business model. By moving from 'cost-plus' contracts to 'firm fixed-price' models, they introduced predictability and economic discipline, fundamentally changing how space launches are sold.
