Lifesight Tech Stack

Marketing measurement platform unifying attribution, mix modeling, and incrementality testing

Software Development New York City, New York 201–500 employees Founded 2017 Privately Held

Lifesight is a marketing measurement platform built on causal inference (PyMC, TensorFlow, PyTorch) running on GCP and AWS. The tech stack reveals a research-heavy org: the presence of Vertex AI alongside statistical libraries (PyMC, R) signals investment in productizing econometric and ML models rather than rule-based attribution. Active projects span incrementality testing, multi-touch attribution, and marketing mix modeling — the full measurement stack. Hiring velocity is decelerating while the org remains engineering-forward (7 engineering, 4 data roles open), suggesting mature product development rather than early hiring ramp.
