Alex Edmans of the London Business School starts our conversation with a complaint. Reflecting on the meeting he just had, he asked: Why do we have to sit through so many meetings where people without any expertise dominate? So often, confidence trumps knowledge—and eventually shapes decisions and outcomes. There are two obvious major problems: Decisions are often made without considering evidence and nuance gets lost along the way. Political polarization is only one of the consequences.

1 Introduction The Lennard-Jones (LJ) potential describes the pairwise repulsive and attractive forces with a relatively simple and mathematically tractable expression. It bears the name of the mathematician-physicist-chemist Sir John Lennard-Jones, Figure 1. Today, it is the most popular building block in molecular modeling and simulation. This contribution describes two episodes from the history of the LJ potential.

Like the 1.5°C goal for climate, responsible tech needs a clear North Star to guide investments and innovations. To build an ecosystem of responsible technology and long-term value, venture capitalists and limited partners need to align on processes, incentives and alternative investment models that go beyond the high-risk “move fast and break things” mentality of the 2010s.

Measure what matters. Disclosures are key. Transparency leads to accountability. Which investor, and in fact regulator, wouldn’t agree with these common-sense business mantras pointing to the need for more objectives and key results (OKRs), key performance indicators (KPIs) and other kinds of metrics? Numbers make things more visible and graspable and often that’s good and necessary.

In September, The Information ran an 'Exclusive' on Garry Tan's rebuttals desperately fighting of his critics. The Y-Combinator CEO who cut staff and parts of the accelerator's strategy (their growth fund), had to confront one critical piece after the other since he took the realm. Some journalists have been asking whether YC is still worth it for companies, a brutal critique given the decade-long dominance of the outfit in the accelerator space.

I was recently invited to a boring looking boardroom on the outskirts of the City of London. It wasn't my first time in this boardroom, but this time, the ESG training VentureESG conducted was for the Leadership Team of the big asset owner. Our goal for the session was easy enough: make sure the top decision makers know what ESG is and how it matters for their VC investments. Or simply put: explain ESG to the executive team so that they allow their minions to put it into practice.
