Seed free open tools until developers adopt them as standards, build a plugin ecosystem so the community extends your reach, then monetize the enterprise layer that sits above adoption.
HashiCorp
HashiCorp, founded in 2012 by Mitchell Hashimoto and Armon Dadgar, builds cloud-infrastructure automation tools including Terraform, Vault, Consul, and Nomad. Its story is a single strategy played out in three acts: seed open-source tools that developers adopt as de facto standards, monetize the enterprise layer on top of that free adoption, and defend the resulting business even when that means bruising the open-source community it was built on. IBM acquired the company for $6.4 billion in a deal that closed in early 2025.
Platform & Ecosystem: turning a provisioning tool into an infrastructure standard with a plugin registry
The problem. In the early 2010s, every cloud (AWS, Azure, Google Cloud) had its own provisioning API and tooling, and every new service HashiCorp might support multiplied the integration work. A single company could never write and maintain connectors for the entire sprawling universe of cloud services, so a monolithic tool would always lag the market it served.
The approach. HashiCorp built Terraform as a plugin-based platform rather than a fixed product, exposing a provider interface so that AWS, Microsoft, Google, and thousands of third parties could write and maintain their own integrations. It then launched the public Terraform Registry as the distribution hub for those providers and reusable modules, making the ecosystem, not HashiCorp's own code, the source of coverage.
How it solved it. The plugin model let Terraform support essentially every major cloud and SaaS service without HashiCorp writing each connector, and "Terraform" became the generic verb for infrastructure as code. Terraform surpassed 100 million downloads, and the Registry hosts thousands of community and vendor providers, making the tool the industry-standard control plane it could never have become as a closed product.
Business Model: open-core monetization and the BSL license change that split the community
The problem. HashiCorp gave away its most valuable software for free, and that very openness became a threat: cloud vendors and managed-service competitors could take the open-source code and sell it as a hosted offering, capturing revenue from HashiCorp's own creation while HashiCorp bore the R&D cost.
The approach. HashiCorp ran an open-core model, free community editions plus paid Enterprise and cloud (HCP) tiers, and then, on August 10, 2023, relicensed its core products from the Mozilla Public License 2.0 to the Business Source License (BSL). The BSL kept the source visible but added an "Additional Use Grant" barring anyone from offering a commercial product that competes with HashiCorp's, directly targeting the free-rider problem.
How it solved it. The license protected the commercial business but fractured the community: within roughly a month the OpenTF manifesto gathered more than 33,000 GitHub stars and pledges from around 140 companies, and the OpenTofu fork was accepted by the Linux Foundation in September 2023. The monetized business nonetheless proved durable enough that IBM agreed in April 2024 to acquire HashiCorp for $6.4 billion ($35.00 per share), closing on February 27, 2025.
Land and Expand: developer adoption first, enterprise features on the upgrade path
The problem. Enterprise infrastructure software is traditionally sold top-down to executives through long procurement cycles, but HashiCorp's buyers were the engineers who actually used the tools, and those engineers do not respond to sales pitches for products they have not tried.
The approach. HashiCorp ran an explicit "adopt, land, expand, extend, and renew" motion: let developers adopt the free tools bottom-up, land a small paid contract once the tool hits production, then expand as teams needed enterprise-only capabilities like role-based access control, audit logging, namespaces, disaster recovery, and performance replication that the community editions deliberately lack.
How it solved it. The expansion engine showed up directly in the numbers: HashiCorp reported a trailing-four-quarter average net dollar retention rate of 131% at the end of fiscal 2023, meaning existing customers grew their spend by roughly a third year over year on average. Terraform and Vault, the two most mature products, together generated over 85% of revenue, and quarterly sales reached $82.2 million (up 49%) in the period around its December 2021 IPO, which valued the company at over $14 billion.
