Notable Clients

I'm proud to have played a part in launching successful businesses like Phonon X Inc. We were able to secure a seed funding round of approximately 5.6 million, as recorded by Crunchbase Inc. This is a huge achievement considering we were a small remote team of less than 10 people. Stories like this drives me to continue helping other businesses launch and thrive.
