Founder / CEO @ ColdIQ | Scale Outbound with AI & Tech 👉 coldiq.com

I’m (Michel) the Founder & CEO at ColdIQ, a sales prospecting agency (+ we compare the latest sales tech, too!).

We worked with 100+ B2B organizations (including SaaS & Agencies!) and are using Clay, Prospeo, FullEnrich, Instantly, Lemlist, Ocean.io - alongside other great sales tools - to run outbound campaigns that flood 🌊 our (and our clients’) inboxes with interested prospects.


We can help you:

• If you’re a B2B business leader who doesn’t have the time to handle your prospecting engine or to hire and manage salespeople… You can outsource your lead gen to us, and we’ll transparently show you the exact way we run your campaigns. (We’ll provide SOPs, too… if it works so well that you want to build your in-house team).


• If you’re a sales leader or an outbound agency owner: We’ll help you set up the exact systems & tools we use to run automated ‘trigger-based’ campaigns that convert like crazy. 


• And… if you simply want to improve your B2B sales automation skills or learn to run these campaigns yourself, we’ll teach you by building a campaign from scratch together with you —from ‘idea’ to ‘running campaign’ (we’ve done it more than 50 times already, and the rumour says people ❤️ed it).


We've launched hundreds of campaigns, so you don't have to.


Thus - if you: 
- are a B2B service/solution provider making > $50k/month
- provide solutions with Lifetime Value > $10k
- want to shortcut your outbound success


We can help.

Send a DM, and I'll share more details.

Hosted by Ivan Falco (Head of Growth) & Kenny Damian (Head of GTM) at ColdIQ.

February 26th - 1:30 PM EST

In case you missed the event....

Here's the link to the webinar recording - https://lnkd.in/eqNfrT7b

Founder & CEO at ColdIQ | Tomorrow’s GTM Systems, Built for you 👉 coldiq.com

Yesterday, > 1400 people watched Kenny Damian build an entire outbound campaign using Claude code.

He wrote a few prompts in the terminal, fed it a list of companies, and then...

Claude Code took over:

1. It scored and prioritised the entire company list against our ICP

2. It found verified email addresses through Apollo’s API

3. When Apollo didn’t have coverage, it automatically pulled in additional enrichment providers to fill the gaps

4. It wrote personalised copy templates on its own (based on our best-performing outreach)

5. Then it uploaded the entire campaign: leads, sequences, and copy... straight into Instantly.ai

It took fewer than 20 minutes.

This was just one of three demos we ran.

Right before that, Ivan Falco showed us how to automate ad campaign creation & 'warm' social prospecting.

Unfortunately, I can't upload the entire video here due to LinkedIn's file size limits.

If you couldn't attend: 

Here is the recording and the full playbook bundle (frameworks, SOPs, templates) so you can try this yourself -

https://lnkd.in/eD-WAHyU

We recently crossed $7M ARR.

Here’s every tool we use to run our business:

1️⃣ Content Engine

LinkedIn generates 100+ leads for us every month.

This includes my account: Michel Lieben [67,000+ followers] 
+ other team members [300,000+ followers combined]. 

I use:

- Taplio for content inspiration & ideation.
- Notion for content planning & calendar.
- Scripe to draw inspiration from specific creators.

I crossed 2,200 YouTube subscribers from 15 videos. 

I use:

- Tella for async video production.
- vidIQ for content discovery & ideation.

We ship 2 articles/week and attract 100,000+ visitors quarterly.

30% now comes from SEO, thanks to free mini-tools we built for lead gen, & programmatic pages we created at scale. 

We use:

- Claude Code to build these out.
- AirOps for programmatic SEO.
- Ahrefs for keyword research.

We have ~10,000 active newsletter subscribers with 40%+ open rates. 

We use beehiiv to send our weekly issues.


2️⃣ Outbound System

We deliver Outbound & GTM services to 80+ B2B clients.

Our entire outbound engine runs on Clay for:

→ Enrichment
→ Personalization
→ Prospect research
→ Workflow automation
→ Signal-based targeting

We also use Claude Code for list building, email copywriting, and automating campaign creation.

Plus specialised tools for:

- AI Agents: Relevance AI, n8n.
- Outreach: Instantly.ai, lemlist, Expandi.
- Lead Sources: Prospeo, Apify, Exa, Openmart.
- Contact Data: Wiza, FullEnrich, Prospeo, LeadMagic.
- Intent + Retargeting: PredictLeads, Common Room, Vector 👻, Fibbler, Midbound


3️⃣ Operations Stack

Our team includes 35 FTEs & ~12 Fractional Freelancers.

We use:

- For internal automations: n8n, Claude Code

- For internal database & documentation: Airtable, Notion, Supabase

- For team communication: Slack, Google Meet, Norrsken Barcelona (office by the sea 🌊)


4️⃣ Inbound Funnel

We book ~100 qualified B2B meetings monthly. 

We use:

- Default (lead routing)
- GA4 + Wistia (analytics + VSL)
- Usermaven (analytics & attribution)
- Webflow & Vercel (website hosting)

For re-engagement:

- Customer.io (email marketing)
- Kondo: Superhuman for LinkedIn DMs (LinkedIn inbox management)


5️⃣ Sales Stack

We closed +$1,000,000 in new ARR last month. We use:

- Attio (CRM)
- Qwilr (proposals)

6️⃣ Billing & Finance

We’re integrating Hyperline for billing our productized offerings. It handles quoting, invoicing, and payment collection in one.

On top of that, we use:

- Ramp (expense & treasury management)
- Stripe, Revolut, Mercury (billing + banking)


P.S: What’s one tool we should absolutely try?

Kenny automates entire outbound campaigns using Claude Code.

...and we recorded a 40-min breakdown anyone can replicate:

You write a few prompts in the terminal, along with a list of companies, and then...

Claude Code takes over by:

1. Scoring & segmenting your lead list against your ICP.

2. Finding verified email addresses via several email lookup APIs.

3. Writing personalized copy on its own (based on best performing frameworks)

4. Uploading the whole campaign (leads, sequence & copy) straight into your sequencer.

The entire process is completed in under ~15 minutes.

And we broke it down to the slightest detail.

You can watch it here - https://lnkd.in/e3t6WRNs


P.S: What's the craziest buildout you've done using Claude Code?

Most companies bet their LinkedIn strategy on the Founder.

We turned 24 employees into LinkedIn influencers:

In the span of 90 days, it led to:

581 LinkedIn publications,

adding up to:
> 43,000 reactions (likes, supports, loves)
> 28,000 post comments
> 34,000 new followers

Craziest part about all this is that I'm convinced most B2B teams can replicate this playbook 'pretty' easily.

P.S: Any tools surprise you?

My cold outreach process that generated 25,000+ leads in 2026

(and got us to $7m ARR with our agency)

1. Build a few relevant audience segments

There are some ‘easy’ targeting wins when you run cold outreach for the first time.

- Companies engaging with your brand
- Companies similar to your best clients
- Companies showing buying intent in your category


2. Map your total addressable market (TAM)

That is, every single company that fits your client criteria.

You can use B2B data sources like: Clay, Wiza & Prospeo to build your account lists according to your chosen criteria (company size, geography, industry)


3. Research your target accounts & segment them into tiers.

- Tier 1 should be your dream clients or perfect fits (similar to your best clients).
- Tier 2 should be good fit clients (similar to orgs you helped).
- Tier 3 should be orgs you believe you can help.

You can prompt AI models within Clay to tier/score accounts, or do it within Claude Code by creating a .md file that includes your scoring criteria to be compared against your account list. 

APIs or tools like PredictLeads, Common Room come very handy here as well.


4. Try reaching your entire TAM every 3-6 months

- For Tier 1 leads: mix manual AE outreach + multichannel engagement = phone (use Nooks) + LinkedIn + email.

Pro tip: make sure to write the first 25-50 messages manually. 
Do the unscalable at first; this is how you’ll uncover patterns you can scale later on.

- For Tier 2 leads: automate multichannel outreach with AI (use Clay + lemlist)

Pro tip: make sure every message is valuable, relevant + personalised to each recipient. Think: “what can I send to my prospect that’ll be helpful to him, even if they ignore me”

(Here I like to think of what’s the first thing I’d do if I were to sign them as clients, and I do it already… for free).

Example: Building a free ‘niche’ lead list for target accounts, with companies/people data of their ideal clients.

- For Tier 3 leads: engage leads at scale with a proper deliverability infrastructure (use Instantly.ai).

Use tier 3 leads as an experimental playground to test out various copywriting frameworks. (Let me know if you’d like to see some high-performing ones; we collected our own list.


5. Respond to positive replies asap.

The faster your replies = the higher your meeting rate.
More meetings = more sales.


6. A few bonus tips:

- The lead list // targeting is the most important element to succeed at cold outreach. Spend most of your time on list building.
- You’re interrupting people’s day whenever you’re reaching out cold. Keep that in mind, make it a ’nice’ interruption (not always possible, but try your best!)
- Implement a proper deliverability setup. The biggest killer of email outreach is messages that land in spam.
- Warm your target accounts. If you have budget, build a target list & run LinkedIn ads to them, so that they won’t be 100% cold when they receive your outreach.


P.S: Anything you’d add?

P.S: What's your favourite GTM API for Claude Code?

Top 27 GTM APIs for Claude Code

This GTM workflow helped us hit $7M ARR

It consistently books us 100+ meetings per month:

1. Our team publishes 150 posts per month

- 24 people publish LinkedIn content in our team
- We incentivise w/ competition & cash prizes
- We write around our prospects' pain points
- We use Taplio + Scripe to find inspiration
- We study hooks & visuals from outliers

↳ We’re launching a new competition for Q2 2026. The goal will be to get > 300 posts/mo.

2. We promote successful posts via Thought-Leader Ads

- This generates extra views at ~$40 CPM.
- We boost posts that generated meetings.
- We check who booked from these posts.
- We boost posts in front of this ICP.

↳ We also use LinkedIn Ads to pre-warm accounts for outbound. Thus, all channels work together.

3. We re-engage leads that interacted with our ads, site or content.

- On the site: we use Midbound & Vector 👻 for website de-anonymization.
- On LinkedIn: we use tools like Trigify.io & Jungler to catch social interactions.

4. We route all qualified leads to a Clay table.

5. These leads are scored/segmented & tiered.

- Claygent does ‘advanced’ inbound research.
- LLMs prompts segment leads into tiers

- These enrichments are performed inside Clay.

7. We re-engage leads via 1 or several channels, depending on tiering.

- We use Instantly.ai, lemlist, Expandi or Nooks for sales engagement.
- We try our best to send valuable, relevant messages.

8. This workflow booked us 1,500 meetings last year.

- We’ll probably beat that in 2026.
- This allowed us to reach $7,000,000 ARR and 36+ FTEs
- Clients are closing 6-figure deals within 90 days, running the same workflow.

300+ hours testing Claude Code vs. Cursor to run our GTM...

Here’s my 'final' vibe marketing stack at $7M ARR:

1. Conductor (free)
- My go-to interface to run Claude Code & Codex's latest models.
- UI is much nicer than a terminal + it lets you effortlessly toggle between Codex & Claude Code.


2. Claude Code ($100/mo)
My central hub for all API & MCP calls.

We leverage it for lots of GTM activities, beyond outbound:

→ Creating mini-tools for lead generation.
→ Data scraping + enrichment workflows.
→ Deep SEO analysis via Google Analytics MCP.
→ Entire ad campaign + outbound campaigns creation.
→ List building through Wiza, Prospeo, FullEnrich & Exa's APIs.

...

3. OpenAI Codex ($20/mo)
I barely touch it, honestly.

Mostly for the occasional build that Opus couldn’t crack.

It plugs natively into Conductor, so maintaining access at $20/mo is an easy call.


4. Cursor ($60/mo)
- I began with Cursor. Loved the UI, so I was running Claude Code inside it.
- I used it to design/build some really sharp landing pages.

...but Conductor now covers everything I need with both Claude Code & Codex baked in, with an even slicker UI so… I'm cancelling Cursor.


5. Vercel
- We host all our mini-apps & our site here.


6. GitHub


7. Lovable
- Relied on it early for prototyping & our first mini-tools.
- Solid starting point, but CC is simply stronger for what we’re doing.

--

APIs (where it gets interesting)

Claude Code is an incredibly handy way to orchestrate API calls.

No need to grasp how APIs function; you just feed it your platform’s API documentation, and it sorts out the connection by itself.

Here are some GTM APIs I wire into it:

- PredictLeads: Company intelligence data (covering hiring signals, tech stacks, and funding details).

Example use case: Calling its API from Claude to reveal target companies’ tech stacks.

- Exa: Generates lead lists in natural language.

Example use case: Call its API to “Find Series A fintech companies in Europe”.

- LeadsFactory: “Find people API”

Example use case: Leveraging it within CC to locate people by job title, given a list of domain URLs // LinkedIn company URLs.

- Google Analytics MCP: This produced one of the most insightful custom SEO reports I’ve come across. It surfaced gaps we had overlooked for months in a matter of minutes.

- Apify to tap into custom scraping actors.

- Openmart: Local B2B database.

How to turn $233,000 in LinkedIn ad spend into > $1,500,000 in closed revenue?

We're showing the entire playbook today. Live

CONTEXT

AirOps had a great product trusted by Webflow, Ramp, Carta and LegalZoom. But their pipeline had been stuck at ~$536K/month for almost a year.

We built a full ABM motion combining outbound + LinkedIn Ads, hitting the same accounts from every angle.


WHAT WE'LL COVER:

Account-Based Outbound
→ Building and tiering target account lists with Clay using fit + intent signals
→ Syncing outbound and LinkedIn Ads to hit the same companies from both sides
→ Signal-triggered plays that changed based on account engagement stage

Thought Leader Ads
→ Why we put 80% of ad spend behind founder content, not product ads
→ Using webinars as an outbound play - 112 positive replies from input-request invites
→ Cross-channel feedback loops between outbound and paid

The Results
→ $7.8M qualified pipeline
→ $1.5M closed-won revenue
→ 164 deals created, 30 closed-won
→ 15x pipeline ROI on $233K ad spend
→ 1,058 outbound replies
→ Ad spend scaled 20x with positive ROI

We won't keep it high-level. We'll show the exact system: TAM to TAL to signal stack to coordinated touches to pipeline.

Hosted by Ivan Falco (Head of Growth at ColdIQ) and Eoin Clancy (VP of Growth at AirOps).
