Problem
Many SaaS products want to add AI features but face complex integration challenges, including managing per-user billing, rate limits, multi‑provider failover, and compliance requirements, which can delay product launches and increase engineering overhead.
Solution
Assistiv offers an AI infrastructure SDK that lets SaaS developers embed per‑user AI capabilities—such as wallets, budgets, rate limits, and tool calls—into their applications within a day. The SDK provides thin wrappers for popular frameworks (Next.js, FastAPI, Express, etc.) and handles streaming responses, context propagation, and automatic provider fallback without imposing runtime dependencies. A multi‑tenant gateway enforces SOC 2‑type compliance, EU/US data residency, and a 99.95 % SLA while managing platform and end‑user wallets, atomic billing, and pre‑flight budget checks. Developers can configure any LLM provider and MCP‑compatible tools through a single OpenAI‑compatible API, enabling unified access to multiple models and third‑party services. The platform’s management plane offers API keys, isolated tenant environments, and a Markdown‑first documentation set that is also consumable by AI agents for seamless integration.
Target Audience
SaaS product teams and platform providers that need to add scalable, compliant AI functionality with per‑user billing and multi‑model support.
Features
- Per‑user wallets with atomic top‑up, debit, and refund operations
- Pre‑flight budget and rate‑limit checks to block over‑usage before model invocation

- Streaming‑first support (SSE, chunked responses) that aligns with framework idioms
- Thin SDK wrappers for Next.js, FastAPI, Express and other stacks, requiring only a fetch‑like call
- SOC 2 Type II audit in progress, DPA on request, and selectable EU or US data residency
- OpenAI‑compatible inference API with tool (MCP) integration and LangGraph agent support
