REFERENCES ARE THE MOST UNDERRATED TOOL IN HIRING

By the time you're calling references on a candidate you want to hire, it can be hard to change your mind. This hiring guide starts the calls after the second interview, with the candidate's permission, and spreads them through the process. Build ten questions about what you still need to know for this particular role. Ask for stories and comparisons with other colleagues instead of adjectives like smart or hardworking. The answers can shape the next interview, including which claims to test. If a reference suggests another person to call, get the candidate's permission first.

Lock-in persisted for a long time because leaving was too expensive and risky. AI changed the cost of migrations. It's now possible to build a purpose-made converter, reimplement the behavior the business depends on, and use agents to move both code and data across.

COMPUTE CAPITAL MARKETS

Compute is the fastest-growing asset class in the world. The demand for compute will likely continue to increase. Supply will remain constrained across chips, memory, power, and data center infrastructure. A new universe of productive financial assets is emerging, which means there will inevitably be robust markets to price, finance, and hedge exposures around the underlying. There is an immense opportunity in building a marketplace with embedded financial primitives to allow producers and consumers of compute to rigorously express risk preferences along the price and availability curve. These new capital markets are uniquely suited for crypto rails.
