After raising more than $7 million from investors and being recently named to Poets and Quants top 100 MBA startups, interior design service provider Havenly and its co-founders—second-year MBA student Emily Motayed, Lee Mayer, and Jessie Dixon—appear to have a blue print for success: flat fees. Customers can sign up for a “small refresh” to one room for $79, or hand over the keys to their whole home for $199 per room. Oh, and it can be done all online. Customers choose from a network of designers, upload photos, work with their pro, and order all the furniture and homegoods through Havenly’s store. Some assembly may be required.
