Sure. I ll be happy to make an introduction to one of customer in that specific segment.
Based on the description of your need and workflow I think Zephyr will be a good fit. The way to organise tests with metadata is similar to what you can achieve with Jira as we leverage the issue type test for all the testing activity.
Zephyr also provide comprehensive APIs for integration with other tools and frameworks. So far we have been able to fulfil the needs of large organizations like Amazon or Citi that have pretty complex stacks and integrations. I would need to know more about your integration needs to make sure there is a fit. So here is my suggestion:
1- I make the introduction to one of our customers having 50 or less engineers. Please could share your contact info at email@example.com
2- I arrange a discussion with our product team to answer any questions you might have about the product and the integrations/APIs
3- you can start a trial if you have positive answers to point 1 & 2 so you don’t waste your time.
Let me know what you think.
