How I Built a Signal-Scoring Pipeline in Postgres (End to End)
Search "lead scoring pipeline in Postgres" and you get generic ETL tutorials, not the GTM version. Here is the actual end-to-end build: the schema, the scoring function, the recompute job, and where it plugs into outreach - the signal layer behind GTM OS.
A Signal Decay Model for Sales: Why Stale Intent Pollutes Your Queue
A buying signal is worth less every day it ages, but most scoring treats a month-old pricing visit the same as this morning's. Here is the decay model that fixes it - half-lives by signal type, the one-line math, and why it keeps your queue ranked on heat instead of history.
How I Built a Lead-Enrichment Webhook That Fires on Every New CRM Contact
Every new contact should be enriched and scored before a rep ever sees it. Here is the build: a webhook on contact-create that calls Apollo, writes firmographics back, and drops the lead into the scored queue - no Zapier seat, no manual research.
The Data Model for a Clay-to-Warehouse Lead Pipeline
Clay is excellent at enrichment and a poor system of record. Here is the data model for piping Clay outputs into a warehouse - the three layers, the keys, and the idempotency that stops re-runs from duplicating your whole pipeline.
Why AI Coding Ran Up a $349 Hosting Bill (and the Two-Setting Fix)
I am not an engineer. I let Claude Code build StackSwap, hit deploy, and got a $349/mo Vercel bill that was 99% build CPU minutes - because every push rebuilt the whole site. Here is the operator teardown and the two settings that took it to ~$30-80.
Build Your Own CRM With Claude Code Instead of HubSpot? An Honest Build-vs-Buy
The viral take is that AI coding killed the CRM - build your own in an afternoon, cancel HubSpot. I run HubSpot daily and built my own GTM system with Claude Code. Here is the honest line: what is worth building, what to keep paying HubSpot for, and where the DIY CRM quietly breaks.
How I Built a GTM Cockpit on Headless Connectors (MCP + API)
A build log: how I assembled a single operator cockpit on top of headless connectors - Apollo, SES, HubSpot, a warehouse - over MCP and API, instead of renting a vendor platform. The architecture, the connector choices, and what broke.
An Oversight Cockpit for Your GTM Agents (Small-Team, Not Enterprise)
As AI agents take over GTM work, you need a place to watch and steer them. The enterprise control planes are overkill for a small team. Here is what a right-sized oversight cockpit looks like - approval gates, one screen, human-in-the-loop - built into one neutral control center.
AI SDR Infrastructure: What's Actually Under the Hood
A map of the infrastructure components that make AI SDRs actually work - data, signals, prompts, feedback loops, guardrails, and measurement.
Autonomous GTM Systems: What's Real Today, What's Hype, and What's Actually Dangerous
A measured map of autonomous GTM - which tasks run unattended today, which need human oversight, and which are still dangerous to automate for operators.
Human-in-the-Loop Sales Automation: The Patterns That Actually Work
The design patterns, human roles, and anti-patterns that make human-in-the-loop sales automation work in production instead of quietly failing.
