EVALS: THE STRATEGIC IP THAT WILL DEFINE THE NEXT ERA OF AI

Evals are comprehensive frameworks that systematically measure and improve AI systems. Making production-quality agents that can actually do work starts with evals. A strong evaluation suite captures the nuances of judgment, tone, and taste, assesses agent use of tools, and breaks tasks down into specific, scorable dimensions. The best companies treat agentic evals as a core quality, reliability, and governance layer.

THE FAKE TRACTION PROBLEM

One of the most dangerous moments in fundraising is when a founder starts to believe their own traction before the market has fully validated it. Founders see early interest as proof their companies are working, while investors are more interested in whether that early interest reduces risk. The difference matters as fundraising is not won by proving that people are curious, but by proving that the company is becoming more investible. Fake traction might get founders into investor conversations, but it often fails during diligence.

"Work whiplash" occurs when constant changes in priorities, poor communication, and unclear roles lead to employee burnout and wasted time. Effective communication and clear delegation can prevent this by ensuring everyone knows decisions, goals, and their responsibilities. Leaders must proactively close the information gap, making sure changes are communicated promptly to prevent employees from feeling undervalued.

RISK IS SEVERELY MISUNDERSTOOD

Top candidates overestimate the risk of joining elite early-stage startups by conflating uncertainty with actual downside. For startups with exceptional teams, strong investors, and important markets, the financial upside can be massive while the downside remains limited because employees can typically return to established companies if the startup fails.

ON THE PRECIPICE

AI is weakening the three forces that historically protected cybersecurity incumbents: switching costs, proprietary data advantages, and distribution. AI agents can automate migrations, reduce the value of exclusive telemetry by improving reasoning over available data, and make product evaluation fast enough for buyers to test and replace vendors more frequently.
