TL;DR: Rishon's AI develops custom AI-enabled business apps; Rishon's runtime runs them as traditional SaaS. Target customers: SMBs.
Most businesses are stuck choosing between generic SaaS that doesn't fit and custom software they can't afford. Rishon leverages AI to eliminate that tradeoff by producing custom solutions with the simplicity of SaaS, at a fraction of the cost.
Rishon can be described as an AI engineer + a high-level specification language + an AI-first runtime. You create a short brief explaining what you want and hand it off to Rishon's AI, or to a human expert, or a team of both. They produce a specification in the Rishon language. Then, Rishon runtime executes it, just as if you found a SaaS solution that fits your needs exactly. Contrary to traditional programming languages, the Rishon language is designed specifically for AI/human collaboration. It concisely and expressively defines the business requirements, fits well within the limited AI context window, and is easily readable by humans.
Rishon's runtime executes the spec directly, providing a correctness guarantee, leaving no room for algorithmic bugs, whether introduced by humans or AI, and requiring minimal QA effort. Rishon embraces the continuous evolution of business applications. Its compiler verifies the consistency of each new version of the spec and validates compatibility with older versions — including data structures and relationships — so the business never suffers from migration risks.
The resulting applications are AI-first — built from the ground up for humans and AI to work side by side. AI agents are first-class participants: they handle phone calls, search the web, interact with third-party software, make decisions (subject to human review), while operating under strict zero-trust security protocols and guardrails set by the business owner.
Rishon also comes with a time machine. Every action in the application is recorded. If you discover that something went wrong three months ago — a misapplied payment, a miscategorized tenant, a wrong conclusion drawn by AI, or even a change in the business spec that shall apply retroactively — you enter the correction with that past date, and Rishon replays everything from that point forward, as if the mistake never happened. No migration scripts, no manual cleanup, no asking your engineer to “fix it in the database.”
Rishon runs in the cloud, natively supporting multi-tenant, multi-user operations that most of today's AI tools lack. Client apps are available for web browsers and natively on iOS, Android, macOS, and Windows — all automatically driven by the same specification while creating platform-specific experiences. For businesses that need a custom-tailored front-end, Rishon also provides an API, making it a natural complement to popular front-end builders like Lovable or Replit.
The $52B agentic AI market needs a secure, structured foundation. SMBs need custom apps they can actually afford. Rishon is the answer to both — currently in beta.
