CEO, Forest Onsen Hotels (Hakone, Japan)

Jun 2017 - Jun 2020 • 3 yrs

Launched and ran a hot-spring hotel in Hakone, Japan. Owned site planning, build-out, hiring, daily operations, pricing, and marketing. This operations background is why my software defaults to usable on day one: small-business staff do not read manuals, and anything that needs an onboarding call does not get used.
