What a founder can learn
Founder takeaway
Choose AI agents by testing them on the real tasks you need done, rather than relying on broad claims about which tool is “best.” Different agents may be better suited to different parts of your work and life.
Why it matters
A task-based comparison turns a noisy tool decision into evidence grounded in your workflow, helping you avoid adopting an agent that performs well in theory but poorly where it counts.
Relevant guides
Put it to work
Pick five recurring, high-value tasks, run each shortlisted agent through the same inputs, and score the outputs using a consistent rubric. Which agent earns a permanent role—and for which tasks?
