Liminal Tech Stack

Verified market intelligence for identity, fraud, and cybersecurity decisions

Software Development New York, NY 51–200 employees Founded 2022 Privately Held

Liminal builds a proprietary intelligence platform (Living Graph) for identity, fraud, and cybersecurity using what they call Grounded Context Engineering — positioning themselves against generic AI models that hallucinate in high-stakes financial and security contexts. The tech stack (PostgreSQL, MongoDB, Node.js, GCP/AWS) supports a data-heavy operation, but the project list reveals active investment in ML infrastructure (fine-tuning pipelines, automated retraining, production ML systems) and embedded analytics, suggesting they're moving from pure data delivery toward AI-assisted decision support. Hiring is accelerating across engineering and sales, with a senior-skewed mix, indicating they're scaling go-to-market alongside product maturation.
