The GTM Engineer bridge.
Zenskar closed the $15M Series A on April 17th. Head of Growth at this stage means you're building the pipeline machine the first NA AE will run on. I just shipped that exact system for Daylit (another Series-A AR-agent company) in 2 weeks. Same play, tuned for billing-complexity ICP, ready before the AE starts.
The first AE inherits whatever you build in the next 60 days.
Growth at post-Series-A is not demand gen volume. It is building the system the first AE picks up on day one. If that system is a signal layer with evidence chains and Slack alerts on real buying intent, the AE ramps in 60 days. If it's a list of accounts and good vibes, ramp slides to month 6 and the board model breaks. The build window is now.
Three things only an internal builder can fix.
Signal-led pipeline is the Growth deliverable at Series A
Top of funnel volume matters less than top of funnel quality. At $75K ACV cycles, the Head of Growth ships a signal layer or ships a problem to the AE on day one.
Founder intuition has to become a system
Apurv and Saurabh know which finance teams feel billing pain. Your job is to write that down as automated signals before the AE arrives. I have the play already built for the adjacent ICP.
HubSpot + Slack is the right plumbing
Signals land in HubSpot account records with full evidence chain. High-fidelity hits ping the AE in Slack. No new tools, no migration. Just the layer that makes the existing stack do real work.
The Daylit signal system, tuned for Zenskar's ICP.
- Weeks 1 to 2
Build 6 buying signals with evidence chain
Finance team hiring patterns, ERP migrations, billing system swaps, M&A activity, CFO transitions, days-since-funding. Each signal carries 4-tier evidence so the AE trusts what they see.
- Weeks 3 to 4
Wire signals into HubSpot with Slack alerts
High-fidelity hits ping the AE in Slack with the signal context already written. Account records in HubSpot carry the why. Day one of ramp, your AE works qualified pipeline instead of cold lists.
Six production signals, shipped in 2 weeks.
Daylit closed Series A and needed an AE-ready territory before the first NA hire ramped. I built the ICP signal layer. Six buying signals piped from raw data sources (theirstack, Crustdata, news APIs) through Anthropic evidence-chain classifiers into HubSpot, with Slack alerts on high-fidelity hits. The first AE walked into a defined territory, not a cold start. 2 weeks. Same fixed-fee discipline.
Same play I would run for Zenskar. Different stack, same fixed-fee discipline.
$15,000, fixed. 6 weeks. One invoice.

Documentation and handoff included, not billed. If volume justifies it after the bridge, $25,000 / 90-day retainer extends the system. Your call, not mine.
