What Lifestack does
Lifestack, operated by DeMind Inc. and headquartered in San Francisco, builds a consumer AI daily planner that schedules tasks around a user's biological energy rather than around calendar availability alone. The product ingests sleep, HRV, recovery, and activity data from wearables including Oura Ring, Apple Watch, WHOOP, Garmin, Fitbit, and Samsung Health (via Apple Health), and layers that data on top of a SAFTE (Sleep, Activity, Fatigue, and Task Effectiveness) circadian rhythm model to assign energy scores to each part of the day. The core engine auto-places deep work into peak cognitive windows, lighter tasks into low-energy periods, and reschedules dynamically when plans change. It also accounts for ADHD-specific patterns such as medication windows, hyperfocus cycles, and afternoon crashes. A 24/7 conversational copilot (Chat With Lifestack) provides in-context daily decision support.
The product is distributed as a cross-platform consumer app available on iOS, Android, macOS, and Chrome, and integrates natively with Google Calendar, Outlook Calendar, Apple Calendar, Todoist, and Trello. Lifestack targets a horizontal consumer base organized around personas: ADHD adults, health-conscious professionals, startup founders, remote workers, and creatives or knowledge workers who depend on deep focus states. Revenue is generated through a tiered subscription model at $7 per month, $50 per year (with a 7-day free trial, marked as the most popular tier), and a $120 one-time lifetime plan, supplemented by a 30% recurring affiliate program for productivity influencers and health coaches. The company is co-founded by Nao Yukawa (CEO) and Hayato Waki (CTO), with a small team of 1-10 people, and reports a user base of 30,000+ on its homepage. The only disclosed funding is a $600,000 seed round in June 2022, and the company appears to be bootstrapped since then, with no enterprise channel, no parent company, and no reported revenue.

Lifestack competitors and assessment
Company assessmentDirect peers
- Clockwise: AI calendar optimization platform primarily for teams. Competes on AI-driven calendar management and integrates with Slack and Google Workspace; does not use wearable data for energy-aware scheduling.
- Akiflow: Unified task and calendar planner that consolidates tasks from multiple sources into a single planning interface. Directly competes on the productivity-planner category and integrates with Todoist and other task managers like Lifestack.
- Motion: AI-powered calendar and task scheduling app for individuals and teams. Direct competitor in automated AI scheduling with significantly more capital and a larger user base; overlaps on auto-scheduling tasks into calendar blocks but lacks wearable data integration.
- Reclaim.ai: AI calendar scheduling tool that auto-schedules tasks, habits, and meetings. Directly competes with Lifestack in AI-driven planning and integrates with Google/Outlook calendars; currently lacks wearable/energy-aware scheduling capabilities.
- Sunsama: Daily planning tool that helps knowledge workers plan each day intentionally. Comparable horizontal productivity positioning with calmer scheduling philosophy; lacks wearable integration but competes for the same 'intentional daily planning' user.
Broad incumbents
- Fantastical: Premium calendar app for Apple platforms with natural language input and scheduling features. Established incumbent in the consumer calendar category with strong Apple ecosystem presence; does not use wearable energy data.
- Todoist: One of the largest consumer task management apps globally. Lifestack integrates with Todoist for task sync but Todoist's scale and brand represent a competitive incumbent in the productivity category that could add scheduling/AI features.
- Notion Calendar (formerly Cron): Calendar app from Notion targeting knowledge workers. Competes in the AI-enhanced calendar space and has Notion's broader productivity ecosystem as a moat; lacks wearable integration.
Emerging players
- Oura: Smart ring with sleep, readiness, and recovery data. Key data source for Lifestack but also a potential competitor if Oura expands into AI-driven daily planning or scheduling recommendations based on readiness scores.
- WHOOP: Wearable with strain, recovery, and sleep tracking. Provides core data signals for Lifestack's energy modeling; WHOOP's own app includes behavioral coaching that could expand into scheduling and compete directly.
