Day One Health

What Day One Health does

Day One Health is a Melbourne-based private coaching practice that delivers structured, data-led health optimisation for executives, senior leaders, founders, and business owners. Its core methodology — branded "The Day One Method" and "Six Pillars of Health Optimisation" — integrates habit stacking frameworks, VO2 Max assessment, biomarker analysis, structured strength and metabolic programming, life-aligned coaching, and accountability systems. The firm sells a 1-2-1 Health Optimisation System delivered in-person in Melbourne or globally online, supplemented by Executive & Corporate Health Programs for leadership teams, in-person VO2 Max and baseline testing using the VO2 Master Analyzer, structured strength programming, and premium thought-leadership workshops and keynote speaking.

The business operates on a sales-led, consultative go-to-market motion anchored by a free confidential 30-minute strategy call. Pricing is quote-based and not publicly disclosed. Revenue streams span subscription-style recurring coaching engagements, one-off testing fees, and professional services revenue from workshops and speaking. Day One Health is founder-led by Mark Sketchley, whose 20+ years of human performance experience with elite athletes (NRLW/AFWL players, Australian freediving champions, world champion boxers, Olympic and Cricket athletes) underpins the brand. Acquisition channels rely heavily on the founder's LinkedIn personal brand, a weekly Executive Performance Newsletter, an articles hub, and downloadable content such as the 14-Day Executive Reset PDF.

The firm is sized at 1–10 employees, has no disclosed institutional funding, no parent company, and no AI/ML capabilities in evidence. Its commercial footprint is anchored in Melbourne but explicitly claims a global client base served via online delivery. Five verified client testimonials across finance, technology, professional services, manufacturing, and consulting are publicly disclosed, each with quantified health outcomes.
