Massinvestor

Massinvestor is a company that publishes the investor database with over 4,000 investors listed. The job it does: designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. They also list Finance and Venture Capital, so expect those to show up in the feature set. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Massinvestor is based in Winchester, Massachusetts and around since 1998. More on massinvestor.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. A short pilot with your real data tells you more than any demo.

If you have worked with Massinvestor, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
