Joseph DeVille
GTM engineer / FDE
Signal feeds, research agents, personalized outbound, deliverability. Measured in pipeline, not activity.
Deep Research + Hermes
What it is
A clickable walkthrough of research and outbound for one meeting. Static on purpose. No live model.
What it does
Hands the rep a research packet, a read on the buyer, a close plan, and three emails that would get better from replies.
GTM account briefs
What it is
An account-research queue for sales.
What it does
Checks a brief against a rubric before a rep sees it.
Forecast Evidence Engine
What it is
A forecast screen for a CRO. Sample data.
What it does
Puts claimed Commit next to Commit that has evidence behind it.
ITAD signal engine
What it is
A ranked list of companies from public events.
What it does
Shows who may buy next. Same idea as new DOT authority, fleet growth, or a renewal.
Neo signal engine
What it is
A hiring-signal list built from public job posts.
What it does
Ranks which employers to call, and why now.
gaiia GTM engine
What it is
A sample pipeline board. Concept demo.
What it does
Shows how leads sit in a queue and get routed to an owner.
SentinelOne pipeline queue
What it is
A sample pipeline board for a security buyer. Concept demo.
What it does
Lets a sales team click through a queue the way they would work real deals.
DNSFilter health console
What it is
A GTM health screen. Concept demo.
What it does
Makes every record show an owner so nothing sits unowned.
Mitek lead to pipeline
What it is
A sample path from lead to pipeline. Not Mitek production.
What it does
Shows how a first touch would move into a deal the sales team can work.
Legalist origination
What it is
A front-office screen for inbound deals.
What it does
Scores those deals and lines up the next outreach.
Five Cortex systems
What it is
A write-up of GTM systems shipped at Cortex.
What it does
Shows how the $1.57M pipeline influence and 17 builds were tracked.
Context Mode
What it is
A live product for teams that run coding agents.
What it does
Gives those agents a shared place to keep context so work does not fall out of the window.
ai-sdr-engine
What it is
Open-source outbound agents you run on your machine. No public website.
What it does
Researches a lead, waits for a person to approve, then reads the reply. Closest public sibling to Cortex Hermes.
ClaudeGTM
What it is
A local tool that starts from a company domain.
What it does
Writes who to sell to, who sits on the buying committee, and a first outreach playbook.
hermes-superagent
What it is
A plugin that sits in front of Hermes workers. Not a website.
What it does
Routes tasks, restarts stuck jobs, and keeps a ledger so work is not dropped.
01–05
Case studies
What it is
Five short write-ups of shipped GTM work.

github.com/josephdeville
What it is
The rest of the public code.
What it does
Opens the repos behind these demos. Not a brochure.
I build GTM systems reps actually use.
TypeScript and Python. Agents, enrichment, routing, outbound, deliverability. One foot in pipeline this quarter, one in process that compounds.
Some of this work maps to fleet compliance GTM (DOT / FMCSA): new authority, fleet growth, renewals. Foley is one audience for that pattern, not the name of the site.
