29 systems, and counting.

across 6 GTM domains · most live in production

Real builds, not slideware. Most shipped inside OpenBorder (a cross-border ecommerce platform); others for agency clients at Vital Traffic Labs, OneAway, and The Deal Lab. Every one runs on evidence: audited data in, verified numbers out.

01

Deliverability Command Center

open →
Inbox placement engine349 inboxes tested; Outlook isolated as the real problem

Real-copy placement tests across the whole sending fleet, so I know which inboxes actually land in the inbox before a campaign goes out.

Domain health checker157/158 domains clean; 1 silent DKIM failure caught

SPF, DKIM, DMARC, blacklist and Spamhaus diagnostics across every sending domain, on a schedule.

Inbox fleet provisioning + warmup548 senders migrated

Moved the whole program off a shared dirty sending pool onto owned, prewarmed infrastructure.

Automated bounce suppression

Verification-backed suppression that keeps undeliverables out of the send and protects domain reputation.

02

Enrichment Engine

open →
TAM enrichment pipelinevalid-contact coverage 48% → 85%

One command sources, qualifies and enriches a 40k-account universe with traffic, ads, firmographics and buying temperature.

TAM account scoring

Problem-size over wallet-size scoring that tiers every account, so reps work the highest-intent list first instead of a flat dump.

Email-finding waterfall23,760 deliverable emails cracked from a dead list

Pattern permutation, coworker inference and catch-all resolution that beats paid finders on hard, faceless lists.

Answer-engine scraper9,287 emails from 12,407 domains at ~$0

Bulk cited-answer enrichment for the questions APIs can't answer, like the owner behind a faceless store.

03

Audit & Intelligence Scrapers

open →
Cross-border checkout auditor98% anti-bot pass; $6-15 per 1,000 stores

Walks a store's real checkout per market and reads back the shipping cost, DDP/DDU incoterm, and which competitor or merchant-of-record they use.

Competitor website auditor84% competitor-ID accuracy on a 334-store bench

Detects the cross-border provider a store runs so a pitch can name the incumbent instead of guessing.

Ad-intelligence scrapers0.80 correlation vs the paid tool, at $0

Free per-country ad counts from Meta Ad Library and Google Transparency Center, validated against a paid vendor.

Audit Copilot (Chrome extension)60,201 audit tasks queued

Published side-panel that turns a human into an audit machine for the stores bots can't crack.

04

AI Sales Copilots

open →
RB2B visitor outbound

Identified website visitors get page-specific outbound based on exactly what they looked at. Map it once, it runs forever.

Job-change auto-enroll

Past champions get relevant outreach within minutes of starting a new job, with do-not-contact checks built in.

Network Mine

The team's combined LinkedIn network matched against open deals to surface warm introduction paths reps didn't know they had.

Reply copilotrewrites at $0.0066 each; learns each rep's voice

Every reply is classified and drafted as an interactive Slack card with send, edit and rewrite, mirrored into Gmail, with a double-reply guard.

Meeting summary bot$0.07-0.10 per call

Sales call to AI recap to a draft in the rep's inbox, a CRM meeting log and a Slack DM, same day.

Follow-up bots + booking routing$4.6M stale pipeline surfaced

Surfaces stale deals and unanswered interested leads, drafts the follow-up, and routes the meeting to the right rep on rotation.

05

Campaign Engine

open →
Email campaign factory4,755-lead campaign written for $7.65 in ~4 min

Describe a campaign in a sentence; the system builds the list, writes unique copy per person, validates every line and uploads it.

Cost-anchor methodology~43% of positive replies trace to the anchor

Lead with the audited per-package cost the prospect is actually eating. It's the measured winning message, not a guess.

Template + spintax system10 campaigns, ~48k leads, $0 marginal copy

Heavy template-level spintax and conditional flavor branches so a big send doesn't share one fingerprint.

EmailBison over SmartLead

Why the whole program runs on EmailBison: SmartLead missed replies, broke webhooks, and priced per-lead in a way that punishes a real CRM.

06

Platform & Infrastructure

open →
OpenClay — in-house Clay replacement729/729 tests green; 50k rows at 60fps

A full lead-enrichment platform with a virtualized 50k-row grid, a money-safe enrichment engine, and an MCP server so agents can drive it.

Claude Code operating system for the team40+ in-house skills

The referential context, skills and memory system behind all of my work in Claude Code, so the GTM engine is operable by command instead of tribal knowledge.

VPS + cron automation fleet10 production crons

Ten standing automations on owned infrastructure: sync jobs, linkers, attribution stampers, copilots and trackers.

CRM cleaning + auto-enrichment81,892 contacts re-attributed

HubSpot hygiene at scale: source-attribution backfill, deal-contact linking, dynamic do-not-contact sync.

Attribution portal

Human-reviewed campaign-to-deal matching, built before the company had multi-touch, then grown into company-wide linear multi-touch through HubSpot.

GTM data scaffolding

Validation statuses, enrichment timestamps and rollback files on every write, so the CRM gets more trustworthy every week instead of rotting.

Outbound-to-CRM sync

In-house replacement for a paid outbound-sync SaaS, on owned workflows at $0 license cost.
