We just launched our vlog:

Brothers Building Business.

Check out episode 1 (full story below):

Here’s how we got here…

My name is Penn, and I run businesses with my brother, Felix.

After both spending around five years in outbound sales, we joined forces to launch our outbound sales agency, StackOptimise.

We scaled StackOptimise to $3M ARR in just two years.

One of the biggest drivers of that growth was LinkedIn content.

We’ve posted on LinkedIn every day since launching, and it has consistently generated leads for the business.

So as we grew the team, we started encouraging everyone at StackOptimise to post too.

But managing content across an entire team quickly became messy.

We realised we needed one central system to create, manage and organise everything.

Enter Blume. Our second business.

Blume is a SaaS platform that helps companies create and manage LinkedIn content across their entire team.

Both businesses are ultimately focused on the same thing:

How do you generate more sales in B2B today?

StackOptimise focuses on outbound.

Blume focuses on organic content and employee-led growth.

And across both businesses, we’re constantly testing new ways to generate leads, close deals and grow using the latest tools, AI and GTM strategies.

That’s what Brothers Building Business is going to document.

No polished founder interviews. No pretending everything is going perfectly.

Just a raw, behind-the-scenes look at us building two businesses in 2026.

The campaigns we launch. The deals we close. The experiments that work. The ones that don’t. And the new strategies we’re using to grow.

If you’re interested in how B2B companies are actually generating sales right now, that’s the core of the vlog.
