Daniel Lubetzky said he once ran on four or five hours of sleep a night while building Kind Snacks, a pace that left him looking like a “phantom raccoon.” He now says founders need limits, real downtime, and a hard stop on constant checking, especially as AI makes it easier to stay available all day.
The former Kind Snacks founder said, “You have to work hard, but you need to find the balance between working hard and also reminding yourself that it’s a marathon, it’s not a sprint.” For startup founders, the practical advice is not abstract: turn off notifications, choose when to check them, and build in a break before exhaustion becomes routine.
Kind Snacks and 2020
$5 billion was the price Lubetzky got for Kind Snacks in 2020, but his warning starts earlier, in the stretch when he said he was getting just four or five hours of sleep a night. He also said he spent little time sleeping, seeing sunlight, or working out while focusing on growth, a routine that pushed him toward the need for decompression rather than more output.
“I would work like crazy, but then sometimes I would just take that morning off, and I would just decompress,” he said. That break was not presented as a luxury; it was the pressure valve he used after especially demanding periods, the kind of reset founders can copy without needing a full shutdown.
AI and constant availability
AI changes the load because, in Lubetzky’s telling, it gives founders more capacity to juggle projects and handle work they once would have handed to others. It also makes it easier to stay plugged in constantly, which can split attention across too many priorities and erase the boundary between work and recovery.
“At some point in your week, you need to find a time to disconnect,” he said. “And truly disconnect.” His examples were concrete: take a walk without a phone, meditate, shower without music, or sit quietly with no agenda. “Turn off all of your notifications,” he said, and “Regain control over your lives by deciding when you want to check and don’t check 3,000 times a day.”
Early-stage pressure
Lubetzky also drew a line between advice and reality. Startup founders will likely face stretches when work demands their full attention in the earliest stages, and he did not pretend otherwise. The difference is whether that intensity becomes a permanent operating system or a temporary phase with built-in recovery.
For founders deciding what to do next, the test is simple: work hard, but do not let the pace become the norm. Lubetzky’s own account points to a narrow operating rule — push when the company needs it, then stop, detach, and return with enough energy to keep going.
