Anduril Industries | Aerospace and Defense | 6000 | $1.0B | United States | CircleCI | CircleCI | Apps Development | 2020 | n/a |
In 2020, Anduril Industries implemented CircleCI to establish continuous integration and continuous delivery pipelines for its Vehicle Autonomy software development. The deployment targeted Apps Development requirements for automated testing, gated releases, and enforceable test coverage policies supporting safety critical robotic systems.
The CircleCI configuration focused on pipeline orchestration, automated unit, component, and integration test execution, and test artifact management for both on-device and cloud test runs. The implementation supported hardware-in-the-loop test patterns and staged release gates that require passing automated test suites before promotion to downstream environments.
Integrations centered on version control integration with Git, CI-triggered deployments into cloud platforms such as AWS, Azure, and GCP, and telemetry collection for observability with monitoring and logging tooling. The pipelines were designed to service the Vehicle Autonomy teams including Ghost product engineering, and to interface with adjacent teams such as Perception, Autonomy, and Manufacturing for end-to-end validation.
Governance and rollout were driven by Test Automation Engineers who established CI/CD best practices, release gating, and automated quality gates embedded in developer workflows. Adoption emphasis included creating repeatable pipeline templates, metrics-driven reliability monitoring, and cross-functional processes to bring CI/CD into routine software and test engineering operations.

AppFolio | Professional Services | 1702 | $951M | United States | CircleCI | CircleCI | Apps Development | 2020 | n/a |
In 2020, AppFolio implemented CircleCI to provide centralized CI orchestration for its Apps Development activities, targeting engineering and Quality Assurance workflows. AppFolio deployed CircleCI alongside an in-house Cypress E2E test automation effort, aligning the application name CircleCI with the Apps Development category and the company quality engineering function.
The implementation focused on pipeline configuration and automated test orchestration, with CircleCI used to define YAML-based pipelines, job-level environment configuration, artifact capture, test reporting, caching, and parallel job execution typical of continuous integration platforms. CircleCI was explicitly configured to run Cypress E2E suites as part of CI gates, with ownership of the CircleCI configuration assigned to the QA engineering team responsible for the Cypress framework.
Operational coverage centered on engineering and Quality Assurance teams, with the senior quality assurance engineers maintaining pipeline definitions and maintaining test automation integration into release workflows. Governance emphasized configuration ownership, version-controlled pipeline manifests, and test orchestration responsibilities driven by the QA function, ensuring CircleCI served as the CI backbone for Apps Development at AppFolio.

Gong | Professional Services | 1781 | $300M | United States | CircleCI | CircleCI | Apps Development | 2017 | n/a |
In 2017 Gong standardized on CircleCI as its CI/CD platform to support its Apps Development activities. The adoption targeted the R&D organization in Tel Aviv-Yafo and aimed to instrument continuous integration and delivery pipelines that span development, test, and production environments.
The CircleCI implementation focused on pipeline orchestration, automated build and test workflows, and deployment automation. Configuration emphasized containerized build environments using Docker and production orchestration patterns that align with Kubernetes, with pipeline definitions and automation scripts to enforce consistent build, test, and release stages.
Integrations explicitly included git based source control workflows, cloud infrastructure on AWS, infrastructure as code tools such as Terraform and AWS CloudFormation, configuration management tools including Ansible and related automation, and relational data stores such as MySQL and PostgreSQL for test and staging connectivity. Operational scope covered dev, test and production environments, and the role of DevOps in managing security, scale and billing decisions was embedded in the deployment and runbook processes.
Governance changes centered on CI/CD workflow standardization, automated gating of builds and environment promotion, and ownership of pipeline tooling by the infrastructure and DevOps teams. The CircleCI deployment contributed to Gong moving to more modern solutions in production, CI/CD and monitoring, and established repeatable processes for deployment, monitoring and operations across its machine-learning based platform.

Macquarie Group | Banking and Financial Services | 21270 | $4.5B | Australia | CircleCI | CircleCI | Apps Development | 2016 | n/a |
In 2016, Macquarie Group implemented CircleCI to manage CI/CD pipelines that supported Dataiku-based ETL development and DataOps workflows, positioning CircleCI within its Apps Development tooling for data engineering teams. The implementation targeted Dataiku practitioners in Melbourne and Sydney and was aligned with the enterprise requirement to enable self-service ETL development and automated pipeline orchestration.
CircleCI was configured to run continuous integration tasks including automated testing, linting, and orchestration of Python-based ETL tools, consistent with Test-Driven Development practices and microservices-based deployment patterns described in the role. The CircleCI implementation emphasized pipeline automation for Python workflows, use of testing frameworks, and integration of Git version management into build and deployment stages, reinforcing reproducible deployment for data transformation code.
Integrations explicitly covered the Dataiku platform and Git-based repositories such as Bitbucket, GitHub, and Gitlab, along with interactions with AWS S3 for data staging and CLI-driven file management. The CI/CD pipelines were designed to hand off artifacts to downstream data ingestion and processing components in the Apache Big Data stack, including Spark, Impala, and Hive, reflecting an Apps Development integration footprint that spans cloud storage, orchestration, and big data processing layers.
Governance and process changes alongside the CircleCI rollout included formalizing DataOps practices, embedding data governance and lineage considerations into pipeline design, and applying agile tooling such as Jira and Confluence for cross-team coordination. The implementation emphasized source control discipline, pipeline ownership by data engineering teams, and automation of testing and deployment steps to standardize how ETL code and microservices are validated and promoted across environments.

Starling Bank | Banking and Financial Services | 3500 | $887M | United Kingdom | CircleCI | CircleCI | Apps Development | 2016 | n/a |
In 2016 Starling Bank used CircleCI as part of its Apps Development toolchain during an iOS prototype to feature complete effort led by a Senior iOS Developer between January 2016 and March 2016. The engagement focused on delivering the mobile application codebase in Swift using Xcode, while CircleCI provided continuous integration for automated build and test orchestration supporting the mobile application development function.
CircleCI was configured to run continuous integration tests alongside unit testing with XCTest under a test driven development workflow. Builds and automated test runs validated new features implemented programmatically in Swift, including a custom UI implementation inspired by Java Swing. Dependency management for third party frameworks was handled using Carthage, with frameworks admitted into the CI pipeline only after security verification.
The implementation required coordination with the Mobile Security team to gate third party components, and regular stakeholder demos to the CEO, CFO, legal, marketing, design and technical teams to show weekly progress. CircleCI automated build verification and test execution from the developer workflow, enabling rapid iteration and consistent validation across feature development.
Governance was enforced through security verification of dependencies and a disciplined TDD approach that embedded XCTest runs into the CircleCI pipeline. The integration of CircleCI into Starling Banks Apps Development workflow established a repeatable, automated developer pipeline for iOS engineering and formalized build and test checks as part of the release cadence.
