Why Open Source Turned Into a Billion‑Dollar Business in 2018 – Key Insights

2018 was a landmark year for open source software, witnessing numerous milestone events as open source merged with commercial software, and showcasing significant progress by Chinese open source companies.

As a VC firm, we invested early in several influential domestic open source enterprises, gaining deep insights into open source commercialization.

Five Billion‑Dollar Companies Merging with Open Source

Only six companies worldwide have market caps over $100 billion (Microsoft, Oracle, SAP, Adobe, IBM, Salesforce). Including VMware (~$70 billion), there are seven such giants.

IBM acquired Red Hat for $34 billion, aiming to strengthen its private cloud capabilities.

Microsoft bought GitHub for $7.5 billion, valuing the developer network over immediate revenue.

Salesforce purchased Mulesoft for $6.5 billion to enhance data integration across its cloud services.

Adobe acquired Magento for $1.68 billion to complement its Experience Cloud with e‑commerce.

VMware bought Heptio (estimated > $100 million) to deepen its Kubernetes expertise.

Open Source Demonstrates Commercial Revenue Capability

Two open source companies IPOed, and two IPOed firms merged.

Pivotal (PaaS) generated $500 million revenue before IPO, valued at $4 billion.

Elastic (search) posted $160 million revenue before its 2018 IPO, valued at $5 billion.

Cloudera + Hortonworks merged (52 billion all‑stock) combining Hadoop‑based products and services, with combined annual revenue near $720 million.

Why Open Source Offers Competitive Advantages

Open source enables rapid market share acquisition, attracting top talent, reducing customer acquisition costs, and fostering ecosystem standards.

It also encourages customer participation, improves code quality through public scrutiny, and can become a de‑facto technology standard.

Key Success Factors for Commercial Open Source

Success hinges on creating customer value, establishing strong competitive barriers, and adopting efficient business models.

Customer Value : Deliver tangible benefits that justify enterprise investment.

Competitive Moat : Offer high‑complexity solutions where alternatives are limited.

Business Model : Product‑type models (commercial licenses) achieve 70‑80% gross margins, while service‑type models (support, consulting) yield lower margins and scale less efficiently.

Open Source Commercial Models

Enterprises typically follow either a product model (dual‑license, commercial editions) or a service model (support, customization), with product models proving more profitable.

Open Source Companies Behind the Ecosystem

Successful open source projects often spawn or are backed by profitable enterprises (e.g., Red Hat, MongoDB, Cloudera), ensuring sustained innovation and reinvestment.

Data from OSS Capital’s COSSCI index tracks open source firms with revenues above $100 million, illustrating the growing economic impact of open source across cloud computing and emerging technologies.
