SmartBear Software is an American privately-held information technology company that delivers tools for application performance monitoring (APM), software development, software testing, API testing, and API management. The company is based in Assembly Square in Somerville in the Greater Boston Area and was founded in 2009 when SmartBear, AutomatedQA, and Pragmatic Software were acquired by Insight Venture Partners. It offers products across API lifecycle, automated testing, behaviour-driven development (BDD), test management, performance testing, mobile testing, monitoring, code review, and three open-source tools. In 2025, SmartBear announced Dan Faulkner as its new Chief Executive Officer.
The company's product portfolio addresses the full software delivery cycle, from design and development through testing and production monitoring. Its API tools, notably Swagger and SwaggerHub, support design-first development and are widely used in the industry. The testing suite includes TestComplete for automated UI testing, ReadyAPI for API testing, and LoadComplete for performance testing. Monitoring solutions like AlertSite provide end-to-end visibility into application uptime and user experience.
History
The original Smart Bear company was founded by Jason Cohen in 2003. Insight Venture Partners acquired three companies - SmartBear, AutomatedQA, and Pragmatic Software - between 2007 and early 2009. These companies operated as AQA Holdings until being rebranded as SmartBear Software in 2010.
After the rebranding, the company acquired Eviware in 2011, leading to API promoter and SoapUI's founder, Ole Lensmar, joining the company. He later served as chief technology officer (CTO) of SmartBear. That same year, the company acquired APM vendor AlertSite. In 2013, SmartBear acquired Spanish APM vendor Lucierna. SmartBear then acquired the Open-Source Community Swagger in 2015 and its founder, Tony Tam, joined the company as head of products for Swagger and the commercial version of Swagger, SwaggerHub. In 2016, SmartBear acquired CrossBrowserTesting.com (CBT), and Ken Hamric, founder of CBT, joined the company as general manager of CrossBrowserTesting.com. In 2017, Francisco Partners acquired a majority stake in SmartBear Software.
The company has integrated artificial intelligence and Machine learning into several of its tools. These include AI-assisted test creation, intelligent defect analysis, and automated API contract testing. The integration of Generative AI capabilities into SwaggerHub and other products has expanded the scope for developers to accelerate API design and validation.
AutomatedQA
AutomatedQA Corporation specialized in automated software testing tools and developer tools. It was founded in 1999 in Las Vegas, Nevada. The company's first product was AQtime, a binary instrumentation profiler to help optimize performance for applications developed with Microsoft and Borland compilers. It was released on November 12, 1999. The first version of TestComplete, AutomatedQA's automated software testing tool, was released in December 2000. In 2004, AutomatedQA released Automated Build Studio, an automated build management and continuous integration application. AQtrace, a new product by AutomatedQA, was released in June 2008. AutomatedQA had received an SD Times 100 award three times, including the most recent SD Times 100 list for 2008. The SD Times 100 award honors the top 100 leaders and innovators in the software development industry as judged by SD Times magazine. AutomatedQA remained an independent subsidiary of SmartBear from 2007 to 2010 until being merged into SmartBear Software.
The origins of the company's testing tools trace back to AutomatedQA's focus on automating the verification of software quality. TestComplete, its flagship product, supports a wide range of application types including desktop, web, and mobile. This foundation has been extended with newer tools that leverage Large language model technologies to generate test scripts from natural language descriptions.
Product Portfolio
SmartBear's product lines are organized into several categories. The API lifecycle suite includes SwaggerHub for API design and documentation, ReadyAPI for API functional and security testing, and SoapUI for open-source API testing. Under automated testing, TestComplete handles desktop, web, and mobile UI automation, while TestLeft enables test automation through IDE plugins. For performance, LoadComplete and its successor, LoadNinja, provide load and stress testing capabilities.
The company also offers code review tools through Collaborator, which supports review of source code, test plans, and requirements. Its monitoring solution, AlertSite, provides global uptime and performance monitoring. CrossBrowserTesting, now known as SmartBear CrossBrowserTesting, allows users to run manual and automated tests across different browsers and devices.
Recent developments have focused on integrating Deep learning models to improve test result analysis and recommendation systems. These features aim to reduce the manual effort in identifying flaky tests and optimizing test suites based on code changes. SmartBear's commitment to Data Augmentation techniques helps its testing tools generate more varied and realistic test data.
Corporate Structure and Leadership
The company is headquartered in Assembly Square in Somerville, Massachusetts. As a privately-held firm, its ownership has been shaped by private equity investments. Insight Venture Partners initiated the founding acquisition, and Francisco Partners took a majority stake in 2017. The management team has included figures like Ole Lensmar as CTO and Tony Tam in product leadership, reflecting the company's tendency to retain talent from acquired firms.
Dan Faulkner was announced as Chief Executive Officer in 2025. Under his leadership, the company continues to expand its AI-enabled offerings. The strategic direction emphasizes streamlining the developer workflow through automated tooling that can highlight best practices across Amazon Web Services, Microsoft Azure, and Google Cloud environments.
Locations
SmartBear is based in the Greater Boston Area and has U.S. offices in Tennessee and Florida. SmartBear also has offices and development centers in Ireland, India, Finland, Poland, Melbourne, and Sweden. These global locations support its multinational customer base and allow for round-the-clock development and support operations. The international presence facilitates local customer engagement and partnerships with cloud providers.
Open Source Contributions
SmartBear sponsors and maintains three open-source tools: SoapUI, Swagger, and Pacto. SoapUI is a widely used API testing tool that supports REST and SOAP protocols. Swagger is a framework for designing and documenting RESTful APIs, and its specification has become a cornerstone of OpenAI's API ecosystem. Pacto is used for contract testing between services. These projects have been instrumental in establishing standards and fostering a developer community.
The open-source Swagger initiative evolved into the OpenAPI Specification, which is now managed by the Linux Foundation. SmartBear's stewardship of this standard has contributed to broad interoperability among AI21 Labs, Anthropic, and Inflection AI platforms that expose APIs. The company's tools are adept at generating client SDKs and server stubs, which are essential for consuming such AI services.
Industry Impact
The company's tools are adopted by enterprises across finance, healthcare, retail, and technology sectors. By enabling continuous testing and API governance, SmartBear helps organizations accelerate software delivery while maintaining quality. The emphasis on Residual Network (ResNet) architectures in image processing and Transformer (architecture) models in natural language processing has led to more sophisticated test oracles that can detect subtle UI regressions and content anomalies.
SmartBear participated in the broader movement toward Curriculum Learning approaches in automated testing, where test generation tasks are sequenced to build complexity gradually. This has shown promise in improving the reliability of end-to-end test suites. The company's research collaborations often reference MIT CSAIL, Stanford AI Lab, and BAIR (Berkeley AI Research) in the context of applying state-of-the-art AI research to practical software quality problems.
Future Directions
The integration of AI into SmartBear's product roadmap is expected to deepen with advances in Multi-Head Attention and Encoder-Decoder Architecture models. Planned features include automatic test maintenance from code changes ablations and anomaly detection in production telemetry using Sequence-to-Sequence (Seq2Seq) models. The company is also exploring the use of Top-P (Nucleus) Sampling and Temperature Scaling to generate diverse yet valid test data sets.
SmartBear aims to position itself as a leader in AI-powered software quality assurance. With the growing complexity of distributed systems and AI services, the demand for sophisticated testing and monitoring tools is likely to increase. The company's strategy involves embedding Gradient Clipping stability techniques into its ML training pipelines for test recommendation engines, and employing Model Pruning to deploy lightweight AI models at the edge.
