Instead of defaulting to skepticism and looking for reasons why something won't work, the most productive starting point is to imagine how big and impactful a new idea could become. After exploring the optimistic case, you can then systematically address and mitigate the risks.

There appears to be a predictable 5-10 year lag between a startup's innovation gaining traction (e.g., Calendly) and a tech giant commoditizing it as a feature (e.g., Google Calendar's scheduling). This "commoditization window" is the crucial timeframe for a startup to build a brand, network effects, and a durable moat.

When a team presents a timeline that feels instinctively too long, trust that gut feeling. It likely signals an over-engineered solution. Complex systems never become simple; they only breed more complexity, causing timelines to expand endlessly. It's better to reset the team or the approach early on.

Instead of optimizing for a quick win, founders should be "greedy" and select a problem so compelling they can envision working on it for 10-20 years. This long-term alignment is critical for avoiding the burnout and cynicism that comes from building a business you're not passionate about. The problem itself must be the primary source of motivation.

During technological bubbles or periods of intense change, it's possible to accomplish seven to ten years of work in one. This 'dog years' effect offers a unique opportunity for compressed learning and value creation, even if the specific venture fails. The key is embracing the frenetic pace.

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.

A visionary founder must be willing to shelve their ultimate, long-term product vision if the market isn't ready. The pragmatic approach is to pivot to an immediate, tangible customer problem. This builds a foundational business and necessary ecosystem trust, paving the way to realize the grander vision in the future.

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.

Nubar Afeyan argues that companies should pursue two innovation tracks. Continuous innovation should build from the present forward. Breakthroughs, however, require envisioning a future state without a clear path and working backward to identify the necessary enabling steps.
