Biggest update to my Ultimate Claude Code guide for GTM since launch.

Major update. Still free.

What's new:

→ More connectors. And the right ones.
The tools to plug Claude Code into your revenue stack, ready to wire.

→ Deployment, done properly.
There are several ways to ship a Claude Code agent in production. Which one is right depends on your team, your stack, and your context. The new version walks through all of them, with a decision tree.

→ New tools to make your agents sharper.
Each one a small upgrade. Together they compound.

The original 4 sections, 42 topics, and 47 ready-to-use skills are still in.

Not a prompt library.

A complete OS for building GTM automation with Claude Code.

If you want it:

1. Like this post
2. Connect with me
3. Comment "Claude" and I will DM it to you
4. ♻️ Repost so other GTM teams can find it

I watched people ship in one day what used to take a quarter.

Last week, I mentored at the Anthropic x FullEnrich x Sillage GTM hackathon.

Three lessons.

1. Claude Code collapsed the build timeline

Some of what got shipped in 8 hours was close to production-ready.

The gap between idea and running software is basically gone.

2. Speed means nothing without data

You can ship the perfect tool in a day. If the contact data behind it is wrong, it’s a dead app.

Nobody rebuilds FullEnrich in one hackathon.
Some layers of the GTM stack cannot be vibe-coded.

Enrichment is infrastructure. Not a feature.

3. Building capacity is not direction

Everyone in that room could build anything.

But that's actually the trap.
Most ideas land as nice-to-haves.

In GTM, good contact data plus real intent signals is what turns “I can build this” into “this should exist.”

That is the actual unlock.

I left exhausted and amazed at how fast this is moving.

Cold calling still beats ads, emails, and social media.
But most people are too soft for it.

Let’s be honest, it’s a difficult channel. 
→ It’s hard to scale.
→ Finding the right data is a pain.
→ And yes, you’ll get rejected a lot.

But this is also one of the best channels for business growth. 
→ Calls give instant feedback, faster than any funnel.
→ You hear objections, and close in real time.
→ You refine your pitch instantly.

Top companies are picking up the phone again.
Because nothing gets you closer to the buyer.

Here’s how I’d structure cold call workflows if I were you:
(that's what we did at TC9)

1️⃣ - Start by calling yourself or hire a closer
2️⃣ - Use a parallel dialer like Aircall or PhoneBurner
3️⃣ - Only call high-intent leads (think warm replies)
4️⃣ - Enrich leads with BetterContact to find cell numbers
5️⃣ - Follow a 3–5 call workflow over 10–14 days

Give this a real 3-month push.
It’s not as difficult as it seems.
It’s a volume and systems game.

And it still works like crazy.

I was looking for a hot take, but I didn't expect this one!

I met with Nadja Komnenic in Barcelona.

She's such a legend, I had to ask her a question about sales!

"What’s the most overrated thing, right now, in the sales industry?"

Nadja has always been authentic, and this time wasn't an exception.

Describing tool FOMO while being head of sales of a tool!

But the pain is real.

Too many leaders are stuck in tech stack purgatory.

You keep chasing the “perfect” tool.
But in fact you're delaying action.

Strategy should drive the tool choice.
Not the other way around.

Tech should amplify what already works.
Don’t scale a broken system.

Get your basics right:
ICP, messaging, channels, offer.

Pick a tool. Start moving.
Optimize as you go.

You'll be in a much better position to ask yourself what tool comes next.

Clearly a solid reminder shared by Nadja here, while I was being attacked by a banana tree!

LinkedIn isn’t just a social media platform.
It’s a superpower for real life.

We crave real relationships.
But social media feels fake.

LinkedIn is the exception. This is the only platform that isn't anonymous.

Lindsay and I started our journey as content creators about the same time.

So when she came to Paris, we had to meet!
And of course, we talked about LinkedIn.

It might sound cliché, but creating content built visibility and trust.

Posting gave me access to CEOs.
I met Ruben, Charlie, Adam, Noam to mention a few.
They're now real friends.

And it all started with showing up online.

LinkedIn forces accountability.
Every profile is tied to a real person.
So people show up as their best selves.
That changes how we engage.

We went from DMs to dinner tables.
Events, collabs, even global travel.

Online connections became real-life bonds.

I use 3 different AI agents systems every day.

One for when I’m at my laptop.
One for when I’m not.
One for when it’s not just me.

1. When I’m at my laptop: Claude Code

In VSCode and Conductor (sometimes the desktop app).

Content, research, knowledge work.
Small apps that make my life easier.

And any GTM play that touches my CRM, my enrichment workflows, etc.

All connected through MCP, API or CLI.
I’m driving. It executes.

2. When I’m not: Hermes

I host it on a VPS, always online, and I talk to it on Telegram.

It knows my professional life and a good part of my personal one.

Research, my routines, reminders, emails, the tools I gave it access to, scraping socials for what’s trending and what actually fits my content strategy.

It sees patterns in what I’m doing and hands me the overview I could never see myself.

Sometimes I just use its capacities when I’m on a trip.
Mostly running on Codex. Testing Grok 4.5.

3. When it’s not just me: Buzz

Also on a VPS, for bigger projects where I need to track everything and put dedicated agents on specific tasks.

It’s model agnostic, so Claude Code, Codex and Grok (and more to come), side by side.

Humans can be in there too, which is the part that makes it a workspace and not a tool.

That’s what I’m adding next.

Very recent. Still experimenting.
But already excited by what I’m seeing.

I use agents in every aspect of my work now.

And for me there's no coming back!

Everyone says cold outreach is dead.
They’re wrong. Here's what's really happening:
 
Prospects haven’t stopped buying.
They’ve just stopped answering irrelevant messages.
 
The problem isn’t outreach.
It’s aimless outreach.
 
That’s why intent-led outbound wins.
It makes every touchpoint count.
 
Here’s the truth:
→ Intent signals tell you who’s ready now.
→ They show you where to focus next.
 
I’ve listed 79 powerful buying signals to help you do exactly that.
 
From job changes to funding rounds to tech installs.
Every single one helps you hit with perfect timing.

I've done the heavy lifting so you don't have to.

Stop guessing. Start targeting.
Outbound isn’t dead. It’s evolving.

Spray and pray won't work anymore.
Here’s why most messages get ignored:
 
Generic templates flood inboxes.
Trust never builds.
 
Time to lead with relevance and context.
 
→ Blasting templates burns bridges fast.
Volume without relevance fails.
 
→ Context turns a cold start warm.
Micro-trust fuels better replies.
 
→ Engagement warms leads naturally.
Automation should enhance. Not replace.
 
Outreach fails when it’s transactional.
It wins when it’s relational.
 
Stop blasting. Start connecting.
Test, iterate, and drop what flops.

Your SDRs are not lazy.
They’re stuck in outdated workflows.
 
Manual prospecting drains hours.
Real selling barely happens.
 
You need systems that turn time into revenue.
 
→ Searching LinkedIn manually wastes 15 minutes per hour.
AI surfaces high-intent leads instantly.
 
→ Writing cold outreach from scratch eats 10 minutes.
Personalization is suggested automatically.
 
→ Updating CRM fields steals 10 minutes.
Auto-sync eliminates redundant admin.
 
→ Following up with cold leads burns time.
Now, 20 minutes go to engaged prospects only.
 
→ Sales conversations used to be rare.
Now, they’re the bulk of an SDR’s hour.
 
Manual work costs you deals.
Systems turn SDRs into closers.
 
Your team’s time should be spent selling.

Your pipeline isn’t broken. It’s being slowly killed.
Systemize everything or fall behind.
 
Leads go cold. Reps forget. Deals die.
No system, no scale. Just chaos.
 
Smart systems remove human error and keep momentum alive.
 
1️⃣ Missed Follow-Ups
Reps forget. Spreadsheets fail. Warm leads go cold.
Systems automatically track replies and trigger timely follow-ups.
 
2️⃣ Bad or Stale Data
Wrong contacts. Bounced emails. Outdated records.
Real-time enrichment and CRM hygiene keep data clean and usable.
 
3️⃣ Random Outreach Timing
Cold cadences hit without context. Replies die fast.
Smart outreach triggers off warm signals like site visits or job changes.
 
4️⃣ No Prioritization
SDRs waste time on low-fit leads while hot buyers get ignored.
Intent-based scoring surfaces the best opportunities in real time.
 
5️⃣ Siloed Tools
CRM, enrichment, and outbound tools don’t talk to each other.
A GTM engine connects your stack and syncs everything seamlessly.
 
Revenue doesn’t fail from bad effort.
It fails from broken systems.
 
Systemize before you scale.
That’s how you win the long game.

Legacy outbound tactics are costing you more than just replies.
Cold outreach is NOT dead.
 
Prospects are numb.
Your tactics are dated.
And your funnel is bleeding money.
 
1️⃣ Spray and Pray ≠ Revenue
Most cold emails go to people with zero buying power.
Teams waste hours scraping LinkedIn for “decision-makers”—and pitch interns.
 
Burnout is guaranteed.
While real buyers slip through the cracks, reps chase ghosts.
 
2️⃣ $500+ per lead = CFO panic mode
You’re spending $17k/month for leads that ghost you.
90% stall at “Let’s circle back” (aka “Never”).
 
Budgets are being slashed.
Nobody’s funding strategies with single-digit ROI anymore.
 
3️⃣ <2% replies = Total silence
Buyers get 75+ cold emails a week.
Yours says “We’re great.” Theirs solves a pain.
 
Guess who gets deleted.
Push harder, sound more robotic. Lose the deal.
 
4️⃣ No insights = You’re flying blind
Traditional outbound gives you zero buying signals.
No tracking opens, engagement, or internal shares.
 
Gut instinct ≠ sales strategy.
You’re gambling, not selling.
 
Modern outbound is smarter, faster, and 10x more targeted.
You need data, intent, and relevance. Not just volume.

The shift we’re seeing is as big as the internet.
Refuse to adapt, and you’ll be left behind.
