Semaphore CI/CD users list

Email list of companies using Semaphore CI/CD

Q: How many companies use Semaphore CI/CD?

Data InfoMetrix tracks 2,800 companies using Semaphore CI/CD, with 13,500 verified contacts at those accounts as of October 2026. The largest groups are SaaS & Technology, Fintech and E-Commerce. Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.

Q: Who buys and manages Semaphore CI/CD inside a company?

Semaphore CI/CD is usually owned by CI/CD for Engineering Teams. Decision-makers include CTO, VP of Engineering and VP of Infrastructure; Build & Release Manager and DevOps Manager shape the choice, and DevOps Engineers and SREs use it day to day. Our Semaphore CI/CD list can include any of these roles.

Q: Which Semaphore CI/CD products or editions can I target?

You can target accounts by the Semaphore CI/CD products they run, including Semaphore Cloud, Semaphore Community Edition, Semaphore Enterprise, Semaphore Test Reports and Semaphore Self-Hosted Agents. Tell us which edition or module matters and we filter the list to those accounts.

Q: What other software do Semaphore CI/CD customers use?

Semaphore CI/CD customers commonly also run AWS, Kubernetes, GitHub, Terraform and Datadog. Semaphore CI/CD is often connected to Bitbucket and Docker, so users of those tools overlap heavily. We can filter any list by this kind of stack overlap.

Q: What are the main alternatives to Semaphore CI/CD?

The main alternatives to Semaphore CI/CD are GitHub Actions, CircleCI and Buildkite. We also keep verified user lists for GitHub Actions, CircleCI and Buildkite, which is useful for competitive displacement campaigns.

Q: When are Semaphore CI/CD customers most likely to buy?

Buying triggers we track for Semaphore CI/CD accounts include CI migration, monorepo adoption, build time initiative and engineering growth. A common pain point is slow builds: long pipelines slow developers.

Q: Can Data InfoMetrix deliver a free sample Semaphore CI/CD contact list before ordering?

Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Semaphore CI/CD criteria—including target job titles, company size, and region—delivered within one business day with no obligation.

Q: How does Data InfoMetrix guarantee email deliverability for Semaphore CI/CD contacts?

Data InfoMetrix provides a 99% email deliverability guarantee on all Semaphore CI/CD datasets. Every contact record undergoes real-time email verification within a 30 to 45-day refresh cycle, backed by a 1:1 hard bounce replacement policy for 30 days after delivery.

Sourcing and compliance. Business contacts come from public company sources, professional directories and opt-in publishing partners, then go through SMTP verification and human review. Lists are for B2B outreach: include an unsubscribe link and honour opt-outs (CAN-SPAM), and have a lawful basis such as legitimate interest when you email people in the EU or UK (GDPR).
