About Us
Portfolio123 was launched in 2004 well before the word “fintech” came into vogue. We are a pioneer in allowing anyone to create a rules-based investment strategy that closely resembles what a human strategy manager does. The motivation was simple: to eliminate the time-consuming, repetitive and emotional process of managing a stock strategy.
All computer models rely on quality data to produce meaningful results.
Therefore in 2012 Portfolio123 made a transition from Reuters to Compustat,
which is supplied by Standard & Poor's Global Market Intelligence.
Then in 2020, a bold decision to add global data partnered us with Factset.
With this move Portfolio123 remains the only provider of this data to individual investors at a reasonable price, thereby leveling the playing field with large institutions.
But no matter how simple and powerful we made our strategy tools, they remained out of reach for most investors. Beginning in 2018 a completely redesigned website was launched to cater to any investor, from the beginner to the advanced. With many new features, all available for free, Portfolio123 is once again a pioneer in making strategy management as easy as 1-2-3!
MeetOur Team
Marco Salerno
Founder & CEO
A software engineer, inventor, and handyman, Marco was introduced to computers at an early age while attending a boarding school in the Swiss Alps. He was the only one to request to be in the computer lab when a shiny new Apple II arrived rather than participate in the skiing outings. After stints at prestigious investment firms like Citadel, he began thinking of ways to automate the repetitive task of managing a strategy. That work eventually became Portfolio123.
Hem Upadhyaya
Head of Special Projects & RIA
Former banker at Northern Trust and researcher for an investment research app he co-founded, Hem has experience in both worlds. After partnering with a friend to start a financial research app, he started managing client investment accounts before coming onboard with Portfolio123 to kickstart the RIA department. He has a very curious personality and enjoys learning new things every day. He's a strong follower of the motto “work hard, play hard” and “Give 100% to everything!”
