  • Clients First – or we’ll go out of business!

32 years, 2 startups and one rock band later . . .

Before the beginning

While bringing tech to Wall Street, future Gorilla Logic co-founders Stu and Ed meet at a party, bond over music, and form a band—Strategic Dance Initiative. Together they launch an amazing music software program and quickly realize that the only people who would buy it have no money.

The real beginning

Still in the tech game, Ed runs Sun Microsystem’s eBusiness practice, while Stu launches the Sun Java Center. Leaving their cush jobs, Stu and Ed consult by day and develop MonkeyTalk, a QA automation tool, at night. People actually pay for it.

Head out on the highway

Stu jams to The Gorillaz while cruising down I25. An “aha” moment ensues, and “Gorilla Logic” is born.  Oracle purchases MonkeyTalk. Gorilla Logic shifts focus to application development and lands a slew of fun, high-profile clients.

15 years of being geeky and counting

The original band of Gorillas moves into their Boulder, CO, headquarters. The company opens a state-of-the-art development center in Costa Rica, home to over 500 Agile developers.

Expanding our borders

Gorilla Logic reaches 500 employees including new CEO, Dan Berg. Co-Founders Stu and Ed join the Board of Directors. The company opens a location in Medellín, Colombia.

Daniel Berg


With previous positions in senior executive leadership at Sun Microsystems, SolidFire, Avaya, Skype, and JumpCloud, Daniel Berg is no stranger to the tech industry. Throughout his career, Daniel has straddled the line between business and technology allowing him to be challenged by various disciplines including enterprise products, consumer software, SaaS, and application services. Honored as a ‘Distinguished Engineer’ at Sun Microsystems, Daniel has a strong grasp of technology and is energized by the unique challenges and opportunities that each business presents.

Daniel’s diverse experience—including several secondments throughout Europe—has taught him to foster excellence in strategy, execution, and innovation by building extraordinary product and technology teams. He truly appreciates diversity in engineering and CI/CD models that stimulate communication, collaboration, and innovation.

As a previous client of Gorilla Logic, Daniel knows and appreciates the value of the nearshore development model. He believes the best way to solve clients’ business problems is to understand their unique challenge, provide high-quality solutions, and foster lasting relationships—all important elements of the business model here at Gorilla Logic.

Daniel’s passion and visionary personality make him an excellent addition to the Band of Gorillas! As a self-proclaimed adrenaline junky, Dan fills his spare time playing with anything with a motor. From motocross to track racing, Dan enjoys the fast things in life.

Meet the Original Silverbacks

Stu Stern

Stu Stern


Stu co-founded Gorilla Logic in 2002, after serving as founding VP of the Sun Java Center, Sun Microsystems’ global Java professional services organization. As VP of Equity Trading Systems Technology at PaineWebber (now UBS), he led the firm’s trading floor into the digital era. While living in NYC, Stu also fronted the 80s techno band, Strategic Dance Initiative (fans are still hoping for a comeback tour).

A self-professed geek with more than 30 years of programming experience, Stu has hired literally hundreds of talented developers who are passionate about using technology to help customers transform their businesses. He occasionally slings code, and loves mixing it up with Gorilla Logic’s customers and engineers (“really smart people doing cool things”).

An “alt-indie guy” who founded a music startup in the late 80s, Stu constantly cycles through new tunes while creating countless playlists. You can usually find him with his axe at Gorilla Logic’s monthly Boulder Geek Jam, or riding his bike at Flagstaff Mountain.

Ed Schwarz

Ed Schwarz


Ed has been delivering software systems for an undisclosed number of years. Before co-founding Gorilla Logic, he was Director of eBusiness Consulting at Sun Microsystems.
Back in the day, he was also on Wall Street exec’ing and tech’ing at Lehman Brothers and Moody’s Investors Services.

After taking seven semesters of physics, Ed graduated from Princeton University with a degree in music. Realizing that musicians do really cool and glamorous stuff but don’t always get paid a lot, Ed landed a “real job” at a law firm where he built a system in Cobol to schedule the firm’s paralegals. Ed’s officemate (also a musician) introduced him to Stu, which led to the formation of Strategic Dance Initiative—and ultimately Gorilla Logic.

Ed often writes and records music at Gorilla Logic’s jam studio. He refuses to compile an ultimate playlist (“too many choices”) but admits, “The Digital Vibrators would definitely be represented.”

Ed lives in New York, so don’t try anything funny…
