Citing a quote from legendary investor Jim Breyer, Miles Clements emphasizes that while the science of VC is valuation, the art is knowing when to ignore it. He shares that Accel missed investing in ServiceTitan, a $9B company, by rigidly adhering to valuation multiples for vertical SaaS, learning a costly lesson about the need for flexibility with generational founders.

While strong data is a necessary condition for investment, it shouldn't be the sole determinant. Focusing too intently on a single metric, like quarterly net new ARR, can cause you to miss the larger secular trend. Data provides guideposts, but you can't lose sight of the bigger picture, the 'forest through the trees.'

Effective due diligence isn't a checklist, but the collection of many small data points—revenue, team retention, customer love, CVC interest. A strong investment is a "beam" where all points align positively. Any misalignment creates doubt and likely signals a "no," adhering to the "if it's not a hell yes, it's a no" rule.

A company can possess incredible, world-leading moats like SpaceX and still be a terrible investment due to an exorbitant valuation. The ability to simultaneously acknowledge a company's greatness and its stock's overvaluation is a critical discipline for avoiding hype-driven investment mistakes.

While diligence is extensive, the decision to make a late-stage investment ultimately hinges on a single core question or belief about a company's unique advantage. If you need to believe more than one or two things for it to be a 10x outcome, it's too complicated and likely won't work.

Investor Chris Reisach argues that if an investment doesn't make sense to you, the problem likely lies with the business, not your intellect. He advises junior VCs to trust their confusion as an adverse signal. A founder's inability to clearly articulate their vision is a fundamental flaw, and investing without true conviction is a recipe for failure.

Overly technical experts can easily dissuade investors from promising companies. A generalist's perspective, applying insights from other industries and focusing on a longer time horizon, can reveal value that specialists, mired in detail and conventional wisdom, might overlook.

To avoid getting swept up in hype, analyze investments through three distinct lenses. First, is the technology truly transformative? Second, does the specific company have a durable competitive advantage? Third, is the valuation disconnected from fundamental value?

A company that cannot articulate its own intrinsic value is poorly equipped to assess the value of an acquisition target. Management has more information about their own business; if they can't value it, they can't reliably value another one, making disciplined M&A impossible.
