One simple growth system

Most B2B founders overcomplicate growth.
You don’t need fancy ads or viral loops.
You need a repeatable system.

Here’s a dead-simple 3-step strategy that helped me grow my agency to $60k MRR (on a shoestring):

→ Create a lead magnet your ICP actually wants
Think checklist, template, swipe file.
Something fast, specific, and useful.
I call this your Trojan Horse offer.
Build it once. Use it everywhere.

→ Build a landing page in under 30 mins
Use Divi (my go-to theme) + Fluent Forms + Clearout for real-time email verification (more on this setup in the GrowthKit system course).
Make the headline benefit-led.
One CTA. No fluff.
Your goal? Get them on your list.

→ Drive traffic with cold email + LinkedIn
Use ListKit to find your ideal buyers.
Use Smartlead to send cold emails.
Post content daily on LinkedIn.
Drive traffic back to your landing page.

Bonus tip?

Set up an automated welcome email to build trust straight away.
No list? No growth. Start today.

I did all this solo.
No team.
No budget.
Just one rocksolid system.

Cold email to grow your email list

Why aren’t more B2B founders using cold email to grow their email list?

Because they think cold email is only for selling.

Wrong move.

Here’s a simple system I use to grow my list with cold email — without sounding spammy.

→ Step 1: Create an irresistible lead magnet
Think checklist, template, or mini-guide.
Something your ideal customer would actually trade their email for.

→ Step 2: Define your 10x customer
Who are they? Where do they hang out? What do they struggle with?
Use the Hyperniche Matrix to lock this in.

→ Step 3: Use ListKit or Apollo to get targeted contacts
Clean the data with Clearout or Truelist (no excuses here)

→ Step 4: Craft a simple, non-salesy cold email
Keep it under 100 words.
Make it helpful, human, and high-value.
Example:
Hey {first name},
Saw you’re doing {X} – I made a free {template/tool} that helps with {Y}.
Happy to share it if you’re interested – no sales pitch, promise.

→ Step 5: Send it using Smartlead
Warm up your inbox.
Send 50-100/day.
Rinse and repeat.

→ Step 6: Add them to your welcome sequence
Send a warm, helpful sequence using Kit – my go-to email tool.
Turn that cold lead into a loyal subscriber.

This works.
It’s how I got my first 1,000 newsletter subs.
No ads. No fluff. Just systems.
