Ehsan's Analysis
At Seed stage, CleanTech companies should benchmark against their own trailing 90-day performance, not industry medians. The absolute number matters less than the trajectory. I have funded companies with below-median metrics that showed consistent 8% monthly improvement over companies with better absolute numbers but flat trajectories. Velocity of improvement is the signal.
