What It Is

GannSystems.Pro is a custom software studio based in East Texas, serving small and midsize businesses. Its services include private AI systems, mobile apps, and web platforms. Rather than positioning itself as a general-purpose AI tool, it focuses on building usable software systems around a company’s real business workflows. Founder Randall Gann is directly involved in communication, scoping, and coding, bringing in partners when needed.

Core Capabilities

Its AI work mainly focuses on private RAG, retrieval pipelines, and AI agents, with an emphasis on using a company’s own knowledge, SOPs, customer information, and edge cases instead of relying on open internet knowledge. The site explicitly states “Your data stays in your tenant” and highlights private cloud, customer tenants, customer-owned keys, HIPAA-ready architecture, and secure-by-default configuration. For web applications, it uses Next.js, React, and TypeScript, with Firestore or PostgreSQL as options. It supports role-based permissions, customer portals, dashboards, real-time features, SSO, CI/CD, and deployment on GCP Cloud Run. The materials do not disclose specific underlying large language models, inference providers, or AI performance metrics.

Pricing and Delivery

Pricing is fully custom. Discovery/Recommendation usually takes from a few hours to one week, and the fee may be waived if it turns into a project. Project builds start in the low five figures in USD, with typical timelines of 4 to 12 weeks. Ongoing maintenance retainers start in the low four figures per month. A written estimate is provided before each project is signed. This model is suitable for businesses with clear operational pain points and budgets, but not for individual users who want to sign up and try something immediately.

Pros and Cons

The main advantages are a high degree of customization and a focus on not forcing business processes into off-the-shelf SaaS. Code is kept in the customer’s repository, and infrastructure runs in the customer’s cloud account, which helps reduce lock-in. Ongoing maintenance is also available after delivery. The downsides are a relatively high price threshold and the lack of self-service, out-of-the-box usage. The team is also limited in size, so complex projects may depend on partners. Public case studies and quantified information about AI capabilities are relatively sparse.

Best Fit and Access from China

GannSystems.Pro is better suited to SMBs in the U.S. or English-speaking environments that need private knowledge bases, internal tools, customer portals, or field-service/scheduling apps. Access and payment options for users in China are not disclosed, and network reachability is unknown. If a localized alternative is needed, Chinese software outsourcing teams, low-code platforms, or AI knowledge base and internal-tool solutions built around the WeCom/Feishu ecosystem may be worth considering.
