Company profile

researched Sep 2026

LastMinute is a healthcare workforce operations company based in Brookline, Massachusetts, that builds software for scheduling and shift coverage in clinical settings. The platform is oriented around the disruptions that healthcare staffing teams face day to day: call-outs, coverage gaps and last-minute schedule changes. Core features include call-out tracking that logs absences and triggers coverage workflows, smart matching that surfaces qualified and available staff for an open shift based on role, credentials, availability and facility rules, and automated outreach that notifies candidates in a defined order to fill shifts.

The product also supports multi-site organizations through cross-clinic coverage requests, shift offers posted to qualified staff at any location in a network, and staff-to-staff shift swaps that preserve credential and coverage requirements. A scheduling module provides a schedule builder spanning units, roles and locations, reusable templates and auto-generation, and tracking of PTO, time-off requests and availability. Analytics features give managers real-time and projected views of staffing levels across shifts and locations, gap detection, and overtime tracking to show where labor costs concentrate.

The company describes its approach as combining proprietary AI and predictive analytics to automate healthcare scheduling, with the stated mission of maintaining safe staffing levels and improving patient care. Its platform is positioned to anticipate potential staff shortages at healthcare facilities before they occur.

Founding story

The company traces its origins to 2016, when founder Leo Dassa accompanied his brother, Dr. Yonathan Dassa, to the Dana-Farber Cancer Institute for chemotherapy following a stage 4 colon cancer diagnosis; Dassa moved to Boston and attended treatment sessions each weekend. Observing how understaffing and burnout among clinical teams affected patient care, and prompted by his brother's remark that "My job is easy. I show up, and the nurses do the rest," Dassa set out to build a staffing solution. The product was developed under the guidance of Chief Nursing Officer Leslie Hirshberg, BSN, RN, DNP, combining nursing expertise with AI and predictive analytics.
