Agent International is a team of seasoned real estate professionals that have varying specialties to create a well-rounded solution to serve their client’s needs. As Globalization continues to shrink the world and people are increasingly becoming “world citizens,” Agent International has fully embraced the need to be internationally connected and understands how critically important it is.

Agent International was conceptualized by local International Real Estate Professional and real estate technology expert, Sophie Aretta. Aretta partnered with local marketing and luxury real estate specialist, Scott Piper to co-create Agent International out of the raising need for a better way to connect buyers with property.

Sophie believes that the ability to market internationally is a tool every agent should have in their toolkit. She feels that in certain markets, in particular the luxury market; agents are likely doing their sellers a disservice by not marketing internationally.

“The vast majority of real estate professionals are only focused on local exposure.” says Aretta, “Agent International certainly has a strong marketing presence in the Bay Area but takes the marketing of their client’s properties to a global level.”

Through a series of strategic partnerships and alliances around the globe, Agent International has an unparalleled ability to market seller’s property locally, regionally, nationally, and internationally to produce maximum exposure and results for their seller’s.
