Stack Moxie

Stack Moxie is a Kirkland, Washington-based software company that provides automated testing and observability for the tools that make up a company's revenue technology stack, spanning marketing automation, sales and customer-success applications and, more recently, AI implementations. The product runs automated QA scenarios and synthetic-data smoke tests through connected systems to verify that forms, leads and data flow correctly end to end, and it alerts users when a process breaks so that outages and bugs can be identified and remediated before they become larger incidents.

Capabilities described by the company include an availability dashboard, live monitors, API health monitoring, launch QA tooling (UTM builder, campaign builder), spreadsheet and Asana triggers, list import, and validation of AI outputs. The company positions its approach as "Test-Driven Marketing" and "revenue observability," and describes itself as monitoring and "AI in the loop" for processes where human review is not feasible. Stack Moxie states it integrates with hundreds of marketing technologies; named integrations include Marketo, HubSpot, Eloqua, Pardot, Salesforce, Microsoft Dynamics, Salesloft, Google Analytics, web forms, email and SEO tools. Alongside the software, the company offers managed services, including managed services for data privacy, ranging from fractional to enterprise-scale teams.

Founding story

Stack Moxie was co-founded by CEO M.H. Lines, who describes a motivation of expanding entrepreneurial opportunity by demonstrating successful enterprises founded and led by underrepresented people; the company lists "Diversity is a Differentiator" among its core values, alongside Radical Hospitality, Low Ego, Do the Work to Understand and Relentless.

Business model

Stack Moxie sells self-service and full-service subscription plans for its testing and monitoring platform, supplemented by managed services engagements. Self-service tiers (Starter and Individual) rely on documentation and weekly customer-success office hours, while Growth and Enterprise plans include onboarding and ongoing customer success support.

Recurring subscription pricing metered by "runs" (one executed activity such as a test, list import or spreadsheet trigger). Published tiers are Starter at $0/month with 25 runs, Individual at $99/month with 100 runs, Growth at $1,000/month with 500 runs, and Enterprise at $4,000/month with 500 runs. Runs beyond plan limits cost $2 each, or less when purchased in prepaid bundles discounted 10% to 50% depending on tier (bundle pricing between $1.00 and $1.80 per run). Enterprise-grade agreements covering unlimited runs, custom integrations and global deployment are negotiated directly.
