I build GTM machines
that run themselves.

Enrichment engines, outbound pipelines, and revenue automations for SaaS and ecommerce teams, designed and shipped end to end. This is what the systems produce.

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

Inbox placement engine

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 checker

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

Inbox fleet provisioning + warmup

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

TAM enrichment pipeline

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 waterfall

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

Answer-engine scraper

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

03

Audit & Intelligence Scrapers

Cross-border checkout auditor

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 auditor

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

Ad-intelligence scrapers

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

Audit Copilot (Chrome extension)

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

04

AI Sales Copilots

Website visitor outbound

De-anonymizes website visitors and fires outbound tailored to the exact pages they viewed, so intent turns into a booked call automatically.

Job-change re-engagement

Watches past champions for job changes and enrolls them into the right sequence the moment they land somewhere new, suppression checks first.

Warm-intro network mapper

Cross-references the whole team's LinkedIn connections against open deals to surface who already knows the buyer, turning cold accounts warm.

Reply copilot

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

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

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

05

Campaign Engine

Email campaign factory

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

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

Template + spintax system

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

EmailBison complete system

The full sending program built on EmailBison end to end: inboxes, sequences, reply routing, and reporting wired into one operated pipeline.

06

Platform & Infrastructure

OpenClay — in-house Clay replacement

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 team

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 fleet

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

CRM cleaning + auto-enrichment

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.
