Plusplus

PlusPlus is a San Francisco-based software company that sells an enablement platform to large technical organizations. The product runs structured internal programs — engineering onboarding, leadership development, AI/GenAI enablement, and peer knowledge sharing — by handling scheduling, enrollment, reminders, content delivery, assessments, tracking, and reporting, so that a small team or single program manager can operate programs across thousands of employees. It combines live events, self-paced learning, and peer-to-peer knowledge sharing, and supports tech talks, workshops, office hours, and structured learning tracks.

The company positions the platform between a traditional LMS (built for top-down, authored compliance and certification content) and a wiki (built for static documentation), targeting the operational knowledge in between. PlusPlus describes a three-step loop: capture (contributors upload Looms, PDFs, markdown pages, or recorded workshops without authoring tools or SCORM), index (auto-transcription, semantic tagging, entity resolution, temporal versioning, and topic/team linking into an internal knowledge graph), and surface (feeding that graph to copilots, search, Slack bots, and MCP-compatible agents). The company markets this as "Collective Intelligence."

Publicly cited customers include Salesforce, Netflix, LinkedIn, Airbnb, Shopify, Roblox, Slack, and Kia. As of 2022 the platform reported roughly 100,000 users. Business-data aggregators list the company in the software development sector with roughly 11–50 employees and San Francisco headquarters at 1081 Mississippi St.

Founding story

Marko Gargenta co-founded Marakana in 2001 to train engineers, and after Twitter acquired it in 2013 he helped architect Twitter University, Twitter's internal engineering onboarding and training system. Observing that engineering, sales, and design teams improved when given tools for peer-to-peer knowledge sharing — and that Twitter scaled headcount effectively because it applied best practices to upleveling employees — he founded PlusPlus in 2016 to productize that model for other high-performance technical organizations rather than adapting a generic corporate LMS.

Business model

B2B SaaS: PlusPlus licenses its enablement platform to enterprise organizations, whose program managers and L&D, TPM, HR, and ERG leaders use it to build and operate internal learning programs. Revenue estimates from third-party data vendors vary widely and are not company-confirmed.

Enterprise software licensing/subscription to organizations deploying the platform for internal programs. Publicly available revenue figures are third-party estimates that conflict (one vendor estimates about $2.5 million annually; another estimates $10–25 million).

Traction

PlusPlus reported approximately 100,000 users as of March 2022 and cites enterprise deployments at Salesforce, Netflix, LinkedIn, Airbnb, Shopify, Roblox, Slack, and Kia. Company materials state that one program manager at Salesforce runs onboarding for more than 18,000 engineers on the platform, and cite customer-reported outcomes including increased workshop attendance at LinkedIn, admin hours saved, and 300+ programs per year run by one person for 5,000 employees at Kia. A development partner reports 14 enterprise-level clients and a partnership spanning more than six years. In February 2021 the company announced plans to hire 100 employees over five years.

Latest developments

The company has repositioned its product around "Collective Intelligence" and an internal knowledge graph that feeds enterprise AI tools, including MCP-compatible agents and copilots, and markets an AI enablement program offering for organizations rolling out generative AI. Roblox is listed among current customers alongside Salesforce, Netflix, and LinkedIn.
