The GTM Engineer bridge.
Mintlify closed the $45M Series B with a16z and Salesforce Ventures in April, and the Head of Growth seat is still open. The pattern at Series B PLG companies: BizOps absorbs the GTM instrumentation work by default. I just shipped the same layer for Daylit (AR-agents/fintech infra, 6-signal HubSpot enrichment, 2-week build). I run the GTM Engineer function in parallel so what you are holding manually becomes a system.
Chief of Staff inherits every GTM gap the org chart does not yet cover.
When Head of Growth is open, the HubSpot instrumentation, the ICP scoring, the routing logic, and the product-signal wiring all default to BizOps. That is your weekly cleanup queue, your ad-hoc dashboards, and the Looms you record explaining why a dashboard moved. The fix is not a new tool. The fix is a signal layer underneath HubSpot that fires the events your reporting assumes already exist. The Head of Growth hire eventually owns it. I run it now so you stop being the bottleneck.
Three things only an internal builder can fix.
ICP scoring lives in a spreadsheet you maintain
If account scoring exists as a Google Sheet that gets manually re-uploaded to HubSpot, it ages out the day after you ship it. Every new product line and every new buyer persona compounds the work.
Product signals do not reach the company record
Mintlify's product fires high-fidelity usage events daily. If those events do not auto-enrich the HubSpot company record, the commercial team flies blind on the strongest signal you have.
Manual reporting masks the real funnel
When you rebuild the weekly pipeline report by hand, the number is only as fresh as your last Sunday night. The org never sees a live read on what is actually moving.
A GTM systems layer that takes the manual instrumentation off your desk.
- Weeks 1 to 2
Audit the GTM workflows currently held in BizOps
Map every HubSpot reconciliation, scoring update, and routing patch you maintain by hand. Identify which ones exist because product and ICP signals never reach the CRM. That is the gap the Head of Growth will not get to for a quarter.
- Weeks 3 to 4
Ship the Daylit-style 6-signal HubSpot enrichment
Product usage, workspace growth, ICP fit, and 3 enterprise-specific signals auto-write to the company record with an evidence chain. Scoring and routing read from clean inputs. The Sunday-night spreadsheet retires.
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 Mintlify. Different stack, same fixed-fee discipline.
$15,000, fixed. 6 weeks. One invoice.

- Account list and buying-committee map
- Sequence build, live send, and deliverability infrastructure
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.

Send me a sentence on how the pipeline reads today, and I will reply within a day with a 1-page scope and an honest read on whether this fits.
