HomeJoy is a startup that connects professional cleaners with clients through an on-demand cleaning service, founded by Adora Cheung and her brother Aaron after they struggled to find a reliable cleaning solution for their own home. The company has grown rapidly since completing Y Combinator's summer program in 2010 and recently received $1.7 million in seed funding, allowing them to hire a team of experts to focus on areas of their expertise. HomeJoy uses Twilio to streamline its communications with customers and cleaners, leveraging the SMS API for appointment notifications and issue resolutions. The company is expanding rapidly, currently serving nine metro areas, and aims to bring clean and happy homes to as many people as possible.
