Founders should be aware of the signs indicating they might be stuck at level two, such as slow sales cycles, high churn rates, and difficulty in generating demand.

At level one product-market fit, your goal is to find three to five customers with a significant problem and deliver a satisfying solution, even if it means being inefficient initially.

If you're stuck at a level of product-market fit, focus on changing the persona, problem, promise, and product to move forward.
