Company profile

researched Aug 2026

Unleash, the business name of Bricks Software AS, is an Oslo, Norway-based company that develops a feature management platform centered on feature flags. The product lets teams decouple deployment from release: code can be shipped to production with functionality gated behind flags that are turned on or off at runtime without redeployment. Core capabilities described by the company include activation strategies and strategy constraints for targeting users, gradual rollouts, kill switches, instant or "surgical" rollback of individual features, variants and payloads, release templates with milestone progression, experimentation, and monitoring [0][4][7].

The platform is offered in an open-source edition and a commercial Unleash Enterprise edition. The open-source version provides a single "Default" project and two environments (development and production), while Enterprise adds multiple projects and environments, role-based access control, change requests, single sign-on, SCIM user provisioning, audit logging, and SLA support. Both hosted (SaaS) and self-hosted deployments are supported, along with multi-region support, air-gapped and FedRAMP-oriented requirements, and a stated design principle that customer data does not leave the customer environment [0][2][3][4][5]. The system is accessed through more than 30 SDKs covering major programming languages (15 official client and server SDKs plus over 15 community SDKs per the GitHub README), an admin UI, APIs, an edge component, a Terraform provider, and integrations with tools such as GitHub, Slack, and CI/CD pipelines [2][3][5].

The company frames its category as "FeatureOps" — an operational layer above DevOps that governs how features are exposed to users after code is live, covering incremental rollout, impact measurement across technical and business metrics, and rapid disabling of problematic functionality. Recent positioning emphasizes governance and real-time control over AI-generated code, citing research from Google's DevOps Research and Assessment group that a 25% rise in AI adoption correlates with a 7% drop in software stability [0][7].

Founding story

The open-source Unleash feature management platform was developed by Ivar Østhus, who serves as Chief Technology Officer; the company operating it is Bricks Software AS, led by Chief Executive Egil Østhus [7].

Business model

Open-core: the Unleash feature management server is available as open-source software (AGPL-3.0 for the main repository, with SDKs under MIT/Apache-2.0), while a commercial Unleash Enterprise edition is sold with additional capabilities such as SSO, RBAC, change requests, SCIM, advanced security, and SLA-backed support. Enterprise is available as a managed/hosted service or self-hosted [3][5].

Paid subscriptions to Unleash Enterprise (managed or self-hosted), entered via a free 14-day cloud trial or free open-source usage; the company reported more than 500 paying customers and stated it has doubled annual recurring revenue each year since its 2022 Series A [3][5][7].

Traction

Company-reported figures include 40M+ Docker downloads, 13K+ GitHub stars (13,747 on the main repository), 100K+ monthly active users, more than 500 paying customers, and annual recurring revenue doubling each year since the 2022 Series A. Named enterprise users include Lloyds Banking Group, Prudential Financial, Wayfair, Lenovo, Mercadona Tech, Visa and Samsung Ads [0][5][6][7].

Latest developments

On 4 March 2026, Unleash announced a $35M Series B led by One Peak Partners with participation from existing investors Spark Capital, Frontline Ventures and Firstminute Capital, bringing total funding to $51.5M. Proceeds are earmarked for product innovation — notably autonomous, end-to-end feature lifecycle management — global expansion, and increased marketing and sales investment. Product messaging now centers on real-time safety, governance and auditability for AI-generated software [0][6][7].

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Positions itself as the leading and most popular open-source feature management/feature flag solution on GitHub, with more than 13,000 GitHub stars and over 40 million downloads; rated "Best Relationship" and "Best Usability" among feature management products by G2 according to the company [0][3][5][7].

Open-source core with self-hosted and air-gapped deployment options, a stated architecture in which data does not leave the customer's environment, enterprise governance features (RBAC, audit, change requests, SAML/SSO), FedRAMP-oriented support, broad SDK coverage, and positioning around governance of AI-generated code. Customers cited by the company contrast it with in-house feature flag systems on cost, scalability and reliability [0][3][5][7].

Technology

A feature flag/feature management server written primarily in TypeScript with a Postgres backend and Docker/Compose deployment, plus a Rust-based edge component (unleash-edge) and Rust flag-evaluation engine and bindings (yggdrasil). Conceptual building blocks include projects, environments, feature flags, activation strategies, strategy constraints, segments, release templates and variants. Client integration is via 30+ SDKs spanning languages such as Node.js, Go, Java, Python, Ruby, .NET, PHP, Rust, Swift, Kotlin and Dart, with APIs, an admin UI, and a Terraform provider [2][3][4][5].

Go-to-market

Developer-led adoption of the open-source project (GitHub, Docker images, live demo, Slack and Reddit communities, learning lab and documentation) converting to paid Enterprise via free trials, self-service sign-up and sales-assisted demos; supplemented by conference and event presence, a user conference, and planned expansion of marketing and sales following the Series B [0][3][5][7].

Software engineering, DevOps, QA and product teams, ranging from individual developers and small teams using the open-source edition to large, security- and compliance-conscious enterprises, including regulated sectors such as banking, insurance and retail [0][5][7].

Geography

Headquartered in Oslo, Norway, serving enterprise customers internationally (references include UK, US and Spanish organizations); the company states it will use Series B proceeds for global expansion [0][6][7].

History

Unleash raised a Series A round in 2022 and reported doubling annual recurring revenue each year thereafter. In March 2026 it announced a $35 million Series B led by One Peak, bringing total funding to $51.5 million [6][7].

Risks & controversies

Most traction and revenue figures (downloads, monthly active users, customer counts, ARR growth) are company-reported and not independently verified in the sources. The open-core model exposes the company to competition from its own freely available open-source edition and from other feature management vendors. The company's own thesis notes that AI-accelerated development is increasing production risk, and it cites DORA research that a 25% rise in AI adoption correlates with a 7% drop in software stability [0][7].
