Kantiv Tech Stack

Pursuit intelligence platform for architecture and engineering firms

Software Development San Diego , CA 51–200 employees Founded 2022 Privately Held

Kantiv builds a pursuit intelligence platform for AEC (architecture, engineering, construction) marketing and business development teams—capturing proposals, project data, and client history to automate go/no-go decisions and proposal generation. The tech stack is heavily weighted toward LLM tooling (LangChain ecosystem, OpenAI, Mistral, Llama, RAG) and Python/Go backend services, with active projects spanning agentic proposal writing, LLM security governance, and event-driven architecture. Pain points cluster around AI deployment risk (securing LLM workloads, compliance, debugging complex AI systems) and operational efficiency (scaling SaaS, integrating ML models)—a pattern typical of early-stage AI product companies still hardening production readiness.
