The launch system behind 30+ GTM releases at JustCall
JustCall shipped a new AI feature every two weeks during its pivot from VoIP to AI-first sales automation. I built the tiered launch system that kept 30+ releases on schedule, then used it to launch AI Voice Agent to $1M ARR within a year.
JustCall is a cloud calling and SMS platform backed by Sequoia, serving 6,000+ customers across 40+ countries. When I joined in December 2024, the company was mid-pivot from a recognised VoIP tool to an AI-first sales automation platform, shipping a new feature every two weeks.
That pace was the real problem. A launch cadence that fast breaks any GTM process built for occasional releases: pages go up without positioning, reps get blindsided on live calls, nobody can say afterward if a launch worked. The fix was a system that scoped every release before GTM work began, so the right assets shipped on time, every time.
The Launch System
Every release got a tier (T0 to T3) before any GTM work began. The tier set the required docs, the assets, and whether tracking and a post-launch review were mandatory.
Ran 27 launches through the system between January and November 2025: 2 flagship (T0), 8 adoption-led (T1), 13 incremental (T2), 4 compliance (T3). Workflows grew 2x to 400+ active workflows across 300+ accounts within a month. Unified Analytics Dashboard went from near-zero to 26,000 weekly events in two weeks. The AI SDR Product Hunt launch hit #19.
AI Voice Agent Launch
AI Voice Agent was the system's highest-stakes test. Competitors pitched "replace your SDR team"; I positioned it as amplification instead, AI handles volume, reps handle judgment.
- Page suite. Built the AI Voice Agent hub plus AI SDR, AI Calling Agent, AI Concierge, and multilingual support subpages, each built around outcomes and industry use cases (real estate, healthcare, solar) instead of feature lists.
- Launch webinar. Ran it end to end: concept, promotion, live demo, follow-up. 200+ registrations, 125 live attendees (62% show rate vs. ~40% industry average), and a 3-email follow-up sequence that converted 29 demo bookings in 72 hours.
- Result. AI Voice Agent reached $1M ARR within its first year, JustCall's highest-margin product and the centerpiece of its AI platform narrative.
Owned Channels: Newsletter & Product Updates
Two channels ran continuously underneath every launch, not tied to any single release.
- Product newsletter. Owned it from February 2025 across customer, channel partner, and tech partner audiences: 43% open rate, 2.3% CTR (roughly 2x the B2B SaaS average), 6,000+ subscribers growing 200 to 400/month. One story per issue, no padding: every issue answered "what does this mean for me" first.
- Product updates page. Identified the need and independently led the redesign of justcall.io/updates: new format, standardised messaging and image system, repeatable publishing process from day one of every release. Became the internal standard for product communication.
27 launches shipped on schedule across 11 months, each scoped to a tier before work began. That discipline let AI Voice Agent, the pivot's highest-stakes release, launch with a clear position and a webinar format that converted, reaching $1M ARR within a year. The newsletter and updates page outlasted any single launch, becoming durable channels the system could lean on. None of it was one-off: it was a system, and it got more reliable with every release.
