Recruiting operations platform automating interview scheduling and coordination; Accel-backed with Slack founder as investor competing with Goodtime.io for high-volume tech hiring.
About
ModernLoop is a recruiting operations platform that automates interview scheduling and coordination for talent acquisition teams — handling the logistically complex process of matching candidate availability with interviewer availability, coordinating across time zones, sending calendar invites and preparation emails, and managing scheduling changes that consume significant recruiter time at high-volume hiring companies. Founded in 2020 in San Mateo, California by Lydia Han and Christopher Triolo, ModernLoop is a Y Combinator W21 graduate backed by Accel and Stewart Butterfield (Slack's founder).\n\nModernLoop's platform integrates with ATS systems (Greenhouse, Lever, Workday) and calendar systems (Google Calendar, Outlook) to automate the interview coordination workflow. When a candidate moves to the interview stage, ModernLoop identifies available interviewers matching the required skill profile, proposes times, sends confirmation and preparation emails, and handles rescheduling requests — reducing recruiter scheduling workload from hours to minutes per candidate. The platform also includes interviewer training tools, interview feedback collection, and recruiting funnel analytics.\n\nIn 2025, ModernLoop competes in the interview scheduling and recruiting operations market with Goodtime.io, Cronofy, and the native scheduling features in Greenhouse, Lever, and Workday for automated interview coordination. The market has grown as engineering teams scale rapidly and recruiting operations become a critical bottleneck — companies hiring 500-2,000 engineers annually need scheduling automation to process the interview volume. The backing of Accel and Stewart Butterfield signals confidence in the platform's potential to become core recruiting infrastructure. The 2025 strategy focuses on deepening ATS integrations, adding AI-powered interviewer matching (recommending which engineers interview which candidates based on skill coverage), and growing enterprise accounts at technology companies with structured engineering hiring programs.
