We are on a mission to transform the traditional hotel model and create a new category of residential hospitality that is fundamentally changing the way we live, work and play away from home. Mint House combines the classic comfort of home and the modern luxury of a hotel, giving guests all the perks and none of the tradeoffs. We’ve ditched losable key cards, long lines, room service and other relics for the things we miss when we travel—kitchens, groceries, workout routines, and the space to spread out. Every part of the Mint House experience is powered by smart technology, making your stay personal, predictable and effortless. Currently operating in major U.S. cities including New York, Miami, Nashville, Philadelphia, and Austin. Founded in 2017, the company has raised approximately $85M from leading venture capital firms like Revolution Ventures and executives from trusted hospitality and real estate brands.

The World Bank is a vital source of financial and technical assistance to developing countries around the world. Our vision is to create a world free of poverty on a livable planet. We are not a bank in the common sense; we are made up of two unique development institutions owned by 189 member countries: the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA). Each institution plays a different but collaborative role in advancing the vision of inclusive and sustainable globalization. The IBRD aims to reduce poverty in middle-income and creditworthy poorer countries, while IDA focuses on the worlds poorest countries. Their work is complemented by that of the International Finance Corporation (IFC), Multilateral Investment Guarantee Agency (MIGA) and the International Centre for the Settlement of Investment Disputes (ICSID). Together, we provide low-interest loans, interest-free credits and grants to developing countries for a wide array of purposes that include investments in education, health, public administration, infrastructure, financial and private sector development, agriculture and environmental and natural resource management.
