Frequently Asked Questions

How does Stack AI ensure enterprise-grade security and compliance?+

Stack AI maintains SOC 2 Type II, HIPAA, GDPR, and ISO 27001 certifications with AES-256 encryption at rest and in transit. They use dedicated infrastructure through Azure OpenAI and AWS Bedrock, offer on-premise and VPC deployment options, and provide explicit guarantees that customer data is never used for AI model training. Enterprise clients receive Business Associate Agreements (BAA) for healthcare use cases and Data Processing Agreements (DPA) with all AI providers.

What makes Stack AI different from open-source alternatives like Flowise or Langflow?+

While Flowise and Langflow offer greater technical customization at zero platform cost, Stack AI provides managed infrastructure, enterprise compliance certifications, professional support, and a more polished user interface. Stack AI targets enterprise buyers who need compliance and support, while open-source alternatives serve developers comfortable managing their own infrastructure and requiring maximum customization.

How does Stack AI's pricing model work and what constitutes a 'run'?+

A 'run' counts each complete workflow execution from start to finish, regardless of complexity or number of blocks. The free tier includes 500 runs monthly with 2 projects and 1 user. Enterprise pricing is custom-quoted based on usage requirements, team size, and specific compliance needs. LLM API costs from providers like OpenAI and Anthropic are separate from platform costs.

Can Stack AI handle complex enterprise workflows with multiple AI models and integrations?+

Yes. Stack AI supports multi-model workflows where different blocks can use different AI providers (OpenAI, Anthropic, Google, Cohere) within the same workflow. The platform includes 100+ enterprise integrations and supports complex logic through conditional blocks, loops, and custom code execution. Enterprise clients often build sophisticated multi-agent systems handling end-to-end business processes.

What kind of ROI can enterprises expect from Stack AI implementation?+

Documented client results include Ducker Carlisle achieving $1 million in operational savings, LifeMD saving 475,000 hours annually, and various organizations reporting 60-80% reduction in document processing time. ROI typically comes from automating repetitive tasks, reducing manual document processing, improving customer response times, and enabling citizen developers to create AI solutions without engineering resources.
