A lean, tech-oriented hotel operator, Life House, has raised $30M in a Series B funding round, it announced this week, which comes as its business model is being put to the test. Life House's model is to be hired by independent hotels, do a cosmetic refresh and use proprietary software to operate the property with minimal staff. At a typical Life House hotel, there may be just housekeepers and a community manager to welcome people and troubleshoot on-site. Functions like booking, check-in, accounting and even housekeeper supervision are all handled with technology.
