Problem

Sterling Labs addresses the productivity failure that occurs when motivated people—especially people with ADHD—are blocked by procrastination, distraction, stress, perfectionism, or difficulty estimating and starting work. The pain is economically meaningful because it converts available working time into unfinished tasks and lost focused hours; the company frames its broader audience as knowledge workers who need to accomplish important goals despite those barriers. The clearest use case is helping someone begin a task they have repeatedly postponed, such as scheduling a doctor’s appointment, then maintaining momentum until they reach a productive flow.

Product / Service

FocusBuddy is an AI productivity coach and voice-based co-pilot that stays on call during a work session. It learns what the user is working on, what remains unfinished, and what has been completed; it can update the to-do list, check in conversationally, help users work through anxiety or perfectionism, redirect distraction, and provide weekly insights into burnout patterns, time-estimation errors, distractions, and peak productivity times. The service is available around the clock, with general use offered free and a personalized version offered to a select group, aiming to provide affordable accountability without requiring a human coach.

Market

The company competes in AI productivity software, particularly the emerging category of voice-first focus, accountability, and personal productivity coaching, with an initial customer profile of highly motivated people with ADHD and an intended expansion to the broader knowledge-worker market. Adjacent competitors include ClickUp, Asana, and Reclaim.ai, while FocusBuddy’s differentiation is its persistent conversational presence during work rather than a conventional task-management interface. Public evidence indicates early but meaningful traction: Focus Buddy launched through Y Combinator’s S24 cohort and Product Hunt, where it reached the number-one product of the day and number-five product of the week, and its company profile reports users spending multiple hours per day on calls with the AI. As of July 2026, Sterling Labs was described as being in stealth after the FocusBuddy product, with $500,000 raised in a 2024 seed round; revenue is not publicly disclosed, so it should be treated as an early-stage company rather than one with demonstrated scaled revenue.
