Echoing the Hippocratic Oath, a venture investor's primary job with a high-performing company is to stay out of the way and not disrupt its momentum. While providing resources for talent, capital, and strategy is valuable, it's secondary to the core principle of not interfering with a team that is already executing successfully.

Value-add isn't a pitch deck slide. Truly helpful investors are either former operators who can empathize with the 0-to-1 struggle, or they actively help you get your first customers. They are the first call in a crisis or the ones who will vouch for you on a reference call when you have no other credibility.

The abundance of capital has shifted the VC mindset from serving founders over a decade to simply "winning" the next hot deal. This transactional approach is misaligned with what founders truly need: a committed, long-term partner who puts the company first.

Many VC firms hire former operators for their expertise, but success isn't guaranteed. The best operator-VCs avoid the urge to "backseat drive" the companies they fund. Instead, they leverage their experience with extraordinary humility, acting as a supportive advisor rather than a replacement CEO.

The hardest transition from entrepreneur to investor is curbing the instinct to solve problems and imagine "what could be." The best venture deals aren't about fixing a company but finding teams already on a trajectory to succeed, then helping change the slope of that success line on the margin.

Competing to be a founder's "first call" is a crowded, zero-sum game. A more effective strategy is to be the "second call"—the specialist a founder turns to for a specific, difficult problem after consulting their lead investor. This positioning is more scalable, collaborative, and allows for differentiated value-add.

In a market where capital is a commodity, early-stage founders prioritize VCs who provide an immediate, tangible edge. The most valuable contributions are warm introductions to land first customers, network access to secure the next round of funding, and unfiltered feedback from experienced operators.

Lior Susan highlights the biggest mental hurdle for former operators becoming VCs: internalizing the power law. Operators are builders wired to fix problems and believe they can turn any situation around. In VC, success is driven by a few massive outliers, requiring focus on winners, not on fixing every company.

The transition from a C-suite operator managing thousands to an investor is jarring. New VCs must adapt from leading large teams to being individual contributors who write their own memos and do their own sourcing. This "scaling down" ability, not just prior success, predicts their success as an investor.
