About
Chorus Sleep is a United States-based employee sleep wellness platform — backed by Y Combinator (W21) — providing employers with a mobile app and coaching program that helps employees improve their sleep quality through audio sessions, behavioral coaching, sleep tracking, and interactive content designed to address the clinical and workplace productivity costs of poor sleep. Founded in 2019 by Ali Abramovitz, MK Hurlbutt, and Warren Runk, Chorus Sleep achieved $2 million in revenue in 2024 with a 13-person team, receiving an M&A acquisition offer in April 2025 — positioning as an employee benefits platform in the growing workplace wellness market where employers invest in targeted health interventions with measurable ROI in reduced absenteeism and healthcare costs.
Microlearning platform delivering training through Slack, Teams, and SMS with 95%+ completion rates; $12M Series A serving Google, AbbVie, and Ford competing with LMS platforms.
About
Arist is a workplace microlearning platform that delivers employee training through messaging channels where employees already spend their time — Slack, Microsoft Teams, SMS, and WhatsApp — using short, spaced-repetition lessons sent directly to employees rather than requiring them to navigate to a separate LMS (learning management system). Founded and Y Combinator-backed, Arist raised $23.6 million total including a $12 million Series A led by PeakSpan Capital, serving major enterprises including Google, AbbVie, ExxonMobil, Novartis, HP, and Ford and achieving 95%+ course completion rates compared to traditional e-learning's 20-30%.\n\nArist's platform allows L&D (learning and development) teams to create short courses (3-5 minute daily micro-lessons delivered over 2-4 weeks) that are pushed to employees in their existing messaging tools. The spaced repetition approach (delivering content over multiple days rather than a single session) is grounded in learning science research showing better long-term retention than marathon training sessions. Managers can track completion rates and quiz performance across their teams through an analytics dashboard without requiring employees to log into a separate system.\n\nIn 2025, Arist competes in the corporate learning market with EdApp (SafetyCulture), 360Learning (collaborative learning platform), Docebo, and traditional LMS platforms including Cornerstone and SAP SuccessFactors for enterprise workforce development. The corporate training market has been disrupted by the observation that most LMS-delivered training has very low completion rates — complex platforms that employees find frustrating to navigate create passive non-compliance rather than learning. Arist's Slack-native delivery removes the navigation barrier entirely. The enterprise client roster (Fortune 500 companies across multiple industries) demonstrates the platform works at scale. The 2025 strategy focuses on deepening Slack and Teams integrations as those platforms add more app capabilities, growing with enterprises standardizing on messaging-first training delivery, and adding AI-powered content creation to reduce the effort of building Arist courses.
