85% reduction in production incidents: How Mutiny reliably ships enterprise-level GTM flows with Momentic

Mutiny is an AI platform that empowers GTM teams to create customer-facing assets that reflect their brand. Trusted by industry leaders including Uber, Amplitude, and GitLab, Mutiny supports high-touch enterprise GTM programs where reliability and execution confidence directly impact revenue and customer trust.

Challenge

Maintaining development velocity without compromising on quality

As one of the fastest-growing enterprise GTM platforms, Mutiny leans heavily on continuous innovation to support its expanding roster of B2B clients. Because each interaction, from researching accounts to generating assets, has a direct impact on revenue, balancing development speed with release quality is their most important problem to solve.

However, as the team continued to ship dynamic, agent-based  flows, their existing testing solutions could not keep up.

At the time, Mutiny’s engineers relied on a mix of service-level unit tests, Datadog synthetics, and light Playwright automation, but none of it covered end-to-end user flows that spanned multiple services. Every time the team shipped a change, those flows had to be retested manually.

“We could never get an automated testing solution to work because only a few of our engineers had the know-how to write and maintain tests in Playwright, and they would quickly get stale as the app evolved,” says Alec Hoey, Staff AI Engineer at Mutiny. “Without visual inspectability, discovering what failed was another major hurdle.”

Rather than allowing instability and regressions to erode customer trust, Mutiny sought an end-to-end solution to replace its existing testing stack. The team’s ideal solution would not only match their iteration speed and product complexity, but also empower all engineers to own testing without commanding internal bandwidth.

That’s when Mutiny discovered Momentic.

Solution

Dependable, engineer-owned testing that drives continuous innovation

With Momentic, Mutiny introduced a robust testing suite that empowers its team to ship fast with confidence, even as its platform continues to evolve.

To ensure Mutiny’s onboarding was quick and painless, the Momentic team created a shared Slack channel, weekly sessions with engineers, and a direct line to the CEO. Within the first week, Mutiny had a complete suite running in production. “Even after our initial onboarding call, I knew we made the right choice,” shares Alec. “The platform was intuitive, easy to use, and backed by a team that was always willing to work around our needs.”

Today, engineers actively use Momentic to define and update tests for the workflows they change most frequently. Instead of writing brittle, locator-heavy scripts, the team describes expected behavior at a high level and effortlessly adjusts tests as the UI and underlying services evolve. This made it practical to keep coverage up to date, even as priorities shifted and new features shipped quickly.

Momentic also enables Mutiny to validate complete end-to-end behavior across multiple services, something that had been difficult to verify consistently in the past. Tests routinely catch regressions caused by seemingly small changes in individual services that would previously have gone unnoticed until a demo or customer workflow failed. With clear visibility into where flows break and the application's state at the time, engineers diagnose issues earlier and resolve them before releases reach production.

As testing became easier to understand and maintain, ownership naturally expanded beyond a small group of engineers. More team members began contributing updates and fixes to tests, turning end-to-end validation into a shared responsibility rather than a specialized task. This reduced the burden on any single engineer and allowed the team to move faster without sacrificing quality.

By validating critical workflows earlier and more reliably, engineers are able to dedicate more time focused on shipping impactful improvements. Now, Mutiny continues to scale development velocity while reducing the risk of regressions reaching customer-facing environments.

“For our entire team to be able to own testing and react quickly to changes in our platform was a game-changer. We finally felt like we had a solution that was solving our biggest problem.”

Results

85% fewer production incidents through a scalable, AI-powered testing layer

Partnering with Momentic enabled Mutiny to accelerate development velocity without the constant concern of regressions making their way into production, even as the team continued to iterate quickly across a complex, multi-service product.

Moving forward, Mutiny is confident that Momentic will remain a core part of its development workflow, empowering the engineering team to expand coverage into new product areas and move quickly without sacrificing reliability.
