GigaCatalyst embeds an AI builder into B2B SaaS products so customers build workflow apps without engineers. 90.8% adoption, $1M pipeline unblocked in 6 weeks.
GigaCatalyst is an embedded AI app builder for B2B SaaS, built by Giga Next Inc. and backed by Y Combinator Spring 2026. It lets non-technical users build workflow apps using natural language inside any SaaS product with REST APIs. Pricing is custom enterprise only. Deployments report 90.8% user adoption, 89% 30-day retention, and $1M in pipeline unblocked within six weeks.
GigaCatalyst is an embedded AI customization platform built by Giga Next Inc., a Y Combinator Spring 2026 company founded in 2025 by Namanyay Goel. It targets B2B SaaS vendors whose enterprise customers routinely request one-off workflow features that the product roadmap will never reach. Early deployments have unblocked $1M in pipeline and prevented $100K in churn within six weeks by letting sales and customer success teams deliver custom functionality without waiting on engineering sprints. The platform embeds a white-label AI builder directly into a SaaS product. Through agentic API discovery, the builder automatically parses the host product's endpoints, query parameters, and data structures, then translates natural-language requests from non-technical users into production-ready microapps. Each microapp runs sandboxed on top of existing APIs without touching the core codebase and inherits the host platform's authentication, row-level access control, and audit logging automatically. GigaCatalyst is built for B2B SaaS companies with enterprise customers where feature gaps cost deals. Documented use cases include predictive parts stockout prevention that saved approximately $500K in equipment downtime at a field service deployment, invoice OCR from phone photos for on-site technicians, and automated maintenance request triage. Across 946 users at early deployments, the platform reports 90.8% adoption, 89% day-30 retention, and 670 microapps built entirely by non-technical users. Pricing is custom and requires contacting the sales team; no public tiers are published. The company states that most implementations pay for themselves within four weeks through increased win rates and churn prevention. The product is web-based and embeds into any B2B SaaS product with REST APIs, with guided two-day installation and no host codebase changes required. Founder Namanyay Goel began programming at age 13 and writes about AI engineering for 4M readers, with bylines in the New York Times, Futurism, and Inc. Magazine. Customer UpKeep reports over 1,000 daily users on GigaCatalyst-powered microapps, and Scalio.app reached 500 daily active users within one month of deploying the platform.

GigaCatalyst is an embedded AI customization platform built by Giga Next Inc., backed by Y Combinator Spring 2026. It installs inside a B2B SaaS product and gives non-technical users, including customers, sales reps, and CS teams, a natural-language interface to build workflow apps and dashboards using the host product's own APIs. No engineering involvement is required after the two-day initial setup.
GigaCatalyst's team handles installation in approximately two days. The platform uses agentic API discovery to automatically parse the host product's endpoints, query parameters, and data structures. The AI builder then appears inside the host product as a white-label feature, trained on the product's own API schema and design language, with no changes to the host codebase required.
Every API call a GigaCatalyst microapp makes routes through the same authentication, authorization, row-level access control, and audit logging as the rest of the host platform. Security is inherited automatically rather than configured separately, and microapps are sandboxed from the core codebase. Customers can only access data they are already authorized to view under the host platform's permissions.
Early customers report $1M in pipeline unblocked and $100K in churn prevented within six weeks. Customer UpKeep grew to 1,000 daily active users, and Scalio.app reached 500 DAU in one month. Across 946 tracked users, GigaCatalyst shows 90.8% adoption, 89% day-30 retention, and 670 microapps built by non-technical users. One field service deployment saved approximately $500K in equipment downtime through predictive stockout prevention.
GigaCatalyst is designed for B2B SaaS companies at Series A or later that have enterprise customers with recurring one-off workflow requests. It is most valuable for product and CS teams that lose deals or renewals because the roadmap cannot prioritize bespoke features. It is not suited for consumer apps, mobile-native products, or SaaS companies without well-documented REST APIs.
No. GigaCatalyst operates on custom enterprise pricing only with no public tiers or free trial. The company states that most deployments pay for themselves within four weeks through higher win rates and reduced churn. Pricing is based on expected usage and is set through a direct sales conversation with the GigaCatalyst team.
Retool and Bubble require customers to learn a proprietary tool and maintain a separate codebase outside the host SaaS product. GigaCatalyst generates microapps that run natively inside the host product using its existing APIs and security model, with no external builder for end users to learn. The output looks and behaves like native product features rather than external dashboards or third-party widgets.
Microapps are self-contained applications that run on top of the host product's existing APIs without modifying the core codebase. They are versioned, audited, and governed separately from the core product release cycle. Generation uses multi-layer validation including static checks, runtime error analysis, and an LLM-as-judge verification pass. A proxy layer handles authentication, tenant isolation, rate limiting, and version control for each microapp.
