Instantly

Instantly is an all-in-one AI-powered sales engagement and lead intelligence platform built to help businesses find, reach, and convert prospects at scale. The platform combines a lead database of over 450 million B2B contacts, multi-channel outreach capabilities (email and LinkedIn), AI-driven personalization, campaign automation, inbox placement and deliverability tools, a built-in CRM, and an AI Sales Agent that autonomously finds leads, writes copy, and books meetings. Originally built as an internal tool for a lead generation agency, Instantly launched publicly in 2021 and grew to over $20 million in ARR by 2024 while remaining bootstrapped. It serves more than 50,000 sales teams globally — including agencies, founders, sales development reps, and enterprise teams — with a focus on high-deliverability cold email infrastructure and outcome-based revenue tracking tools.
