The Platform
Elsie moves fluidly through existing laboratory environments, carrying samples, consumables, and materials between instruments with precision and care. Designed for the demands of regulated labs, built in San Diego.
Our proprietary lab orchestration software monitors every instrument, robot, and process in real time. It dynamically dispatches the nearest available robot, sequences tasks, and ensures continuous throughput with complete traceability.
The Problem
Modern labs have automated individual instruments, but the spaces between them remain stubbornly manual. Samples sit waiting. Technicians are paged. Handoffs are missed. Every manual transfer introduces delay, variability, and risk. Tactus closes that gap.
How It Works
The orchestrator monitors all connected instruments in real time. When a stainer completes a batch, a centrifuge finishes spinning, or a rack needs loading, it knows.
The nearest available robot is automatically assigned and routed to the task. No manual scheduling. No wasted time.
Elsie picks up, transports, and places samples at the next station, with full traceability logged at every step. The workflow never stops.

Partnership
The collaboration pairs Vistapath's Sentinel AI-powered grossing platform with Elsie by Tactus, an autonomous laboratory assistant, to create the first integrated path from specimen imaging to robotic specimen handling.
Event
Elsie by Tactus shared the stage at CAP26 in Las Vegas, then spent three days meeting pathologists and lab leaders. The questions they asked tell us where the field is headed.
Announcement
An independent CPA firm examined our Security, Availability and Confidentiality controls from April 1 through July 1, 2026, and issued our SOC 2 Type II report.
