Fission Labs Tech Stack

AI-first product engineering from prototype to enterprise scale

Software Development Sunnyvale, CA 201–500 employees Founded 2008 Privately Held

Fission Labs is an AI and product engineering firm building systems where intelligence is architected from day one, not bolted on. The tech stack reveals a dual-track operation: deep ML/LLM infrastructure (TensorFlow, PyTorch, Hugging Face, LLMs via Gemma and Mistral) paired with AWS cloud-native tooling (Lambda, API Gateway, CloudFormation), now adopting LangChain and LlamaIndex to operationalize RAG at scale. The hiring acceleration (8 roles in 30 days, 70% engineering-focused with 4 leads) signals capacity expansion for larger client engagements.
