No infrastructure. No ICP. No SDRs. Pipeline needed anyway. Chirp Labs had a product ready for the market but zero GTM infrastructure. No sending domains, no ICP definition, no buying signal detection, no CRM visibility. They needed pipeline conversations without the cost and ramp time of hiring a single SDR. The challenge wasn't just building outreach it was building an entire signal-based motion from scratch, in 30 days, that could generate qualified pipeline automatically and scale without headcount. Infrastructure and enrichment had to be locked in before a single email was sent. THE CHALLENGE Before vs. After Before ONEGTMLAB Zero outbound infrastructure no sending domains, no inboxes, no warmup No ICP definition who to target, how to score, and when to reach out all undefined No signal detection outreach entirely timing-blind, no buying window triggers Zero CRM visibility no attribution from signal to meeting to pipeline Needed pipeline without the cost of hiring a single SDR After ONEGTMLAB Full GTM stack live in 30 days: domains, inboxes, warmup, Clay ICP segments, signal layer 4-Tier ICP scoring model built and validated with Claygent AI running continuously Every sequence trigger-based funding, tech installs, or intent events, zero spray-and-pray 100% pipeline attributed to the exact signal that triggered each outreach Zero SDR headcount required to generate pipeline conversations What We Built ## Three systems. One connected motion. GTM Engineering Foundation Domains, inboxes, warmup, Clay ICP segments, and signal detection full outbound infra live in 30 days. Zero SDR headcount required to generate pipeline. Signal-Triggered Sequences Multi-signal detection feeds AI-personalised sequences via Instantly. Every email triggered by a real buying signal funding, tech installs, intent. Zero spray-and-pray. Pipeline Visibility Stack ICP lists, context cards, A/B tests, CRM dashboards every meeting attributed to the exact signal that triggered it. Signal to Closed Won, full visibility. What We Built Full GTM stack. Zero SDR hires. 30 days. 30d Full GTM stack live from zero 4-Tier ICP scoring model built and validated 0 SDR hires needed 100% Pipeline attributed to signal source Chirp Labs went from pre-revenue with no GTM infrastructure to a live, compounding signal-based outbound motion in 30 days. Pipeline conversations started flowing before most agencies would have finished onboarding. And every meeting was tied back to the exact signal that triggered it.
