Specialized AI startups still have room to win, a16z says

a16z says vertical AI startups should look for markets with four traits: work that repeats often enough to learn from; tasks where judgment matters; experts who can quickly evaluate output and explain what to improve; and room to start with one task and take on more of the job. Together, those conditions can create a strong learning loop, a16z says, giving specialized startups a way to build an advantage.
