What is PlusPlus?

PlusPlus is the Collective Intelligence platform for high-performance technical organizations. It runs the programs that matter most — engineering onboarding, leadership development, AI Enablement — and turns every program into a knowledge graph that makes teams and AI measurably smarter. Founded in 2016 by Marko Gargenta, PlusPlus grew out of Twitter University, the internal system that onboarded Twitter’s engineers as the company scaled. Today, one program manager at Salesforce runs onboarding for 18,000+ engineers on PlusPlus. Netflix, LinkedIn, and Airbnb run their most important programs on it too.

our story

How did PlusPlus start?

2001

Marakana

Marko Gargenta founds Marakana, training engineers at the world’s fastest-moving companies before anyone in the industry called it “enablement.”

2013

Twitter University

Twitter acquires Marakana. It becomes Twitter University — the internal system that onboards Twitter’s engineers as the company scales. It works because it was built by engineers, for engineers, inside a fast-moving technical organization, not adapted from a generic corporate LMS.

2016

PlusPlus

Marko founds PlusPlus to bring that same discipline to other high-performance technical organizations. The bet: the programs that shape how a company runs — how fast people ramp, how well they lead, how the org adapts — deserve infrastructure built for them, not spreadsheets and rigid LMS platforms built for compliance checkboxes.

Today

Collective Intelligence

PlusPlus runs the programs that matter most at Salesforce, Netflix, LinkedIn, and Roblox. One PM at Salesforce runs onboarding for 18,000+ engineers on it. Every program run on PlusPlus now feeds a knowledge graph that surfaces what your best people know — to your teams, and to your AI. We call it Collective Intelligence.

why we exist

Why does PlusPlus exist?

High-performance technical organizations run programs that shape everything: how fast people ramp, how well they lead, how the company adapts when the ground shifts. Most of these programs run on tools that were never built for them: spreadsheets, Zoom links, rigid LMS platforms built for compliance checkboxes.

PlusPlus is different on two levels that work as one. First, we run the program itself: the scheduling, enrollment, content, and reporting that let one person run onboarding for thousands.

Second, every program you run generates knowledge worth keeping. We capture it, connect it, and put it back in front of the people — and now the AI — that need it. That second part is what we call Collective Intelligence, and it’s the reason PlusPlus gets more valuable every time you use it.

“Everyone has the same AI. Nobody has your knowledge.”

1Capture
Anyone can share what they know, in formats they already use. No authoring tools required, because everyone in your organization is an expert at something.
2Index
Everything shared flows into your organization: connected, searchable, and readable by machines as well as people.
3Surface
That knowledge feeds your AI tools directly, so your assistants and search stop giving generic answers and start knowing your business.

core beliefs

Our Operating Values

Delivering enablement; from our team to yours.

Shoshin

“In the mind of an expert, little is possible. In the mind of a beginner, everything is possible.”

With a passion for mastery, we encourage each other to learn, adapt, and stay on the cutting edge. Shoshin is about humility.

Gusto

“The credit belongs to the man who is actually in the arena… because there is no effort without error and shortcoming.”

Be in the arena. Fail Fast and Fail Forward. We value courage, effort, and dedication over avoidance of failure.

Ubuntu

“If You Want to Go Fast, Go Alone. If You Want to Go Far, Go Together.”

We believe in creating an environment of trust that allows for unbiased observation, selfless sharing, and respectful acknowledgment.

What do teams running PlusPlus say?
