Year 2 building StackOptimise 🚀

Here’s what we shipped this year:

1️⃣ Launched the world’s first GTM Engineer course. 
2️⃣ Released the $1M Messages eBook. 
3️⃣ Launched our newsletter - 15k subs in 8 months.
4️⃣ Grew the team from 2 to 17.
5️⃣ Expanded our client base from 8 to 20+.
6️⃣ Rebuilt our website - monthly traffic up from 4k to 30k/month.
7️⃣ Became 3× certified experts in B2B sales-tech.
8️⃣ Expanded service line (LinkedIn outreach & RevOps). 

Year 1 was survival.
Year 2 was systems and scale.
Year 3 is where everything compounds.

Onwards.

Welcome to the team, Viktor. 

He’s only a few weeks in, but we knew straight away he was built for GTM Engineering.

We assigned him three clients on day one.

One of them launched a week after he started. Their target was 28 leads per month. He smashed that target in 3 days. 

Beyond the numbers, his technical depth is insane.

Custom landing pages and AI-generated videos personalised to each lead… fully bespoke GTME workflows that would take most people months to figure out.

This is exactly the level we’re building towards at StackOptimise. Elite operators who ship fast and seriously raise the bar.

If you’re an elite operator who wants to build at this pace, we’re still hiring - come join us: https://tally.so/r/m6a5rY

Cold email and LinkedIn DMs serve the same goal - but they work in slightly different ways.

We’ve run thousands of both everyday, and here’s what we’ve learned 👇

1️⃣ Copy
Cold emails need to sound professional and stripped down.
LinkedIn DMs work best when they sound like something you’d actually say.

2️⃣ Volume
Cold email = scale. 20–30/inbox/day.
LinkedIn = slower pace. Around 200 new connections/week/profile. 

3️⃣ Rules
Email success comes from relevance and proof - direct, simple, and credible.
LinkedIn success comes from consistency - showing up, commenting, and sharing useful content.

4️⃣ Follow-up
Email: 3-5 value-led touchpoints. No empty followups. 
LinkedIn: max 3 messages, spaced out, keep it social.

5️⃣ Tools & Testing
Email: test multiple versions - value, case study, pain question.
LinkedIn: test different DMs at scale, double down on what gets replies.

6️⃣ Results & Setup
Cold email: higher volume, lower reply rate, easy to scale.
LinkedIn: smaller volume, higher engagement, harder to scale.

Both channels work - but for different reasons.
Email is the engine.
LinkedIn is the accelerator.

The best outbound strategies use both — working together, not competing.

$250k ARR closed this week.

We’re scaling hard. We need more hands.

GTME applications @StackOptimise ⚙️: https://tally.so/r/m6a5rY

You’ll learn GTM Engineering at the highest level - plus a platform to build your brand and establish yourself as a recognised leader.

Felix and I only spotted the opportunity in outbound (AI-driven sales + GTM engineering) because we’d spent 15 years collectively in B2B sales. If we weren’t deep in that world, we wouldn’t have seen it. 

People talk about “eureka moments” like flashes of inspiration. Ideas that magically fall out of the sky. They don’t. As Zuckerberg says, this is a dangerous lie.

Your ideas are a product of your knowledge.
Your knowledge is a product of your experiences.
The deeper your experiences, the better your ideas. 

So don’t get emotionally attached to the first draft of a business idea - it’s just the starting point. Because early on, your business will likely change direction anyway (we've pivoted our model 3 times in 2 years). 

And the deeper you get into your domain, the more opportunities emerge. We’re now seeing entirely new ways to scale the business - ideas we simply couldn’t have accessed without being in the trenches long enough to earn that level of insight.

Don’t refrain from entrepreneurship because you question your initial idea - that idea is the stepping stone to unlocking great ideas. Get started.

How we generated $450k ARR for our agency in the last 3 months:

Cold email.

A 6-step cold email sequence.

Not 2 steps.
Not 3 steps.
Six.

Because when done properly, a longer sequence compounds your credibility.

This is the most powerful sequence I’ve ever created.

Here’s why it works:

1️⃣ We identify 22+ unique personalisation points per lead.
2️⃣ Every email builds on the last. There’s a cohesive narrative. 
3️⃣ Zero reminders. Every step adds new value.
4️⃣ The tone is so human it disarms people.
5️⃣ Lots of pattern disruptors. Copy that makes the reader pause and think: “Ok… this is different.”

When you stack all of that across six well-crafted touches, you create something rare: a sequence that starts conversations with people who normally ignore cold email.

The industry keeps preaching 2 - 3 steps.
But if each step compounds, you can scale it up. 

And if we can make it work pitching outbound service (the hardest, most saturated service to pitch via outbound), we can make it work for your business.

Ok, I'm super biased. 

But I really believe this is the Age of the Outbound Agency.

Let me explain why 👇

1️⃣ Ramp time
SDRs take months to get going. You need to train people, test scripts, build lists, and wait for results. With an agency, you start seeing leads within weeks, sometimes days. 

2️⃣ Experience level
Most SDRs are entry-level. They learn on the job - which usually means learning with your accounts. Agencies are made up of specialists who’ve already run hundreds of campaigns. You skip the learning curve.

3️⃣ Tech stack
In-house teams often use old tools or limited software budgets. Agencies already have the full stack - data tools, enrichment layers, AI personalisation, automation - all integrated.

4️⃣ Data and optimisation
SDR teams often lack the volume or data to learn fast. Agencies run thousands of sends per day across clients, so they can spot patterns instantly and keep improving results.

5️⃣ Risk
Inexperienced SDRs are susceptible to bad practices that can destabilise performance, like burning your domain or TAM. Agencies protect deliverability with domain pools, warm-up systems, and smarter targeting logic.

6️⃣ Experimentation
A/B testing rarely happens consistently in-house. It’s slow, and SDRs don’t always have the time or know-how. Agencies live and breathe iteration. They test constantly - messaging, timing, CTAs - and double down on what works.

7️⃣ Cost
An SDR setup means salary, tools, management, and turnover. An agency gives you a whole team, stack, and strategy for a fraction of the cost.

Right now, agencies have the edge because outbound has become a technology game. The power lies in the tools, data, and automation - and agencies are the ones moving fastest to harness it ⚙️
