Top Tech Startups in Massachusetts, US in 2026

> Why Castle? So many Americans dream of owning a home but face a harsh reality once they get there. Maintenance, repairs, and running costs can leave many homeowners even more stressed, strained, and financially insecure than they were before. We believe that homes can still be incredible sources of wealth and security for millions of Americans, but that homeowners deserve better data to make better choices when it comes to managing their biggest asset. That’s why Castle is building payments infrastructure for the $3T spent on the home each year — starting with a bill-pay mobile app to help homeowners automate, consolidate, and reduce their spend. > Why you? We want to work with talented, curious, and creative people with many different experiences and perspectives who care deeply about our customers and want to help them solve real problems. A sense of humor and love of dim sum are a bonus. If that sounds like you, we want to work with you.
