Gigacatalyst has launched a public demo of its embedded AI builder that enables SaaS customers to create custom features without engineering resources.

The platform connects to existing product APIs, learns data models and design systems, then allows non-technical users to build applications through natural language descriptions. The system operates inside the host product under the company's brand.

Founder Namanyay Goel said the platform addresses a common enterprise software challenge where large customers need unique workflows that either create engineering backlogs or force workarounds.

Real-world applications show business impact

One Series B customer reported significant results from user-built applications. A maintenance manager created a parts stockout prevention system by describing: "show me which parts will run out in the next 2 weeks based on usage over the last 90 days, accounting for vendor lead times." The resulting app prevented approximately $500,000 in emergency downtime.

Other applications include invoice OCR from phone photos for field technicians and emergency triage systems for restaurant chains. A pizza chain facilities manager built a priority matrix that automatically routes "walk-in freezer not cooling" as critical while "dining room light flickering" goes to low priority.

The platform operates through four technical layers: agentic API discovery that parses endpoints and data structures, generation with multiple validation steps including static checks and runtime analysis, custom compilation and sandboxing for speed optimization, and a proxy layer handling authentication and rate limiting.

Gigacatalyst reports 2,000 daily users across five businesses, with over 900 applications built and 70% 30-day retention. The public demo allows users to input any SaaS product's API URL or homepage to begin building custom features.

The company positions itself as "Lovable, but built on top of YOUR platform," targeting SaaS companies serving diverse enterprise use cases that generate frequent customization requests.

Users can access the demo at app.gigacatalyst.com to test the platform's capabilities with their existing software infrastructure.
