Founder at Chapters Agency

It all started back in 2015 - I joined Woodpecker.co as one of the first salespeople. About a year later, I started building the sales team and took over inbound sales. We grew the company to $4M in ARR by 2021. Then I decided it was time to move on.

In 2023, I founded Chapters Agency - and now leading an awesome team, working with clients across the globe. We help companies drive consistent growth and land high-quality clients through smart, modern outbound strategies.

I'll be honest - I used to avoid working with custom software development companies.

The market is saturated, competition is huge, and prospects get bombarded by hundreds of similar outreach emails. It's one of the toughest niches for cold email.

But one of our partners introduced me to a US-based dev team - genuinely top-tier people, not cheap, but exceptional at what they do.

I liked them so much that I decided I wanted to help. It felt like a great challenge and a great case for us.

After miles of iterations, the first month brought some responses, but not enough. I kept trying different angles, different segments, different messaging.

Then, at the start of the second month, things started clicking.

Below are results from a campaign I launched just 5 days ago - we've already got 9 positive replies and first meetings booked.

A good reminder that even in a brutal niche like custom software development, cold email still works if you go deep, iterate, and truly understand the offer.

It's official - this is one of the most successful outreach campaigns we've done (in terms of engagement).

We tried it with several clients, and it works every time.

If you're going to a conference, just get the attendee list, see who's actually relevant to your business, and send them a short email.

That's pretty much it. More meetings, no magic.

Would you recommend working with Chapters Agency? 🤔

Closed a great customer from my own outbound. Started the campaign yesterday. I think they will be happy, and hopefully we'll build a forever-long relationship :) sounds like a love story haha 😄

Just received this testimonial from Abdullah Abdelkafi at Nomupay - really grateful to share it.

We started working together back when they were still Total Processing. After Nomupay acquired them, we continued the partnership and kept delivering consistent results.

Fintech is competitive, so early on we spent time testing different angles, markets, and signals to find what actually resonated. Once we dialed that in, things became much more predictable.

The best part of this project has been working with Abdullah. He's engaged, provides clear feedback, and genuinely collaborates. That kind of partnership makes all the difference in getting great outcomes.

Client Testimonial: Nomupay & Chapters Agency

Customer feedback loop.

A few years ago, I was honestly afraid of asking customers for feedback too often. I'd send results, assume everything was okay, and move on.

Until one day… 

We worked with a customer, generated tons of leads, and two months later, they came back saying most of them were out of scope.

Their criteria were very specific, and I didn't check properly. I relied on a team member and didn't verify it myself.

It was a hard lesson, and honestly - pretty embarrassing.

But it taught me something important.

In work and in life, we must learn to put ourselves in other people's shoes and really understand their perspective.

Now, I constantly ask for feedback. Even when I'm worried I'll hear something critical - I still ask.

I'd rather hear it early and improve than avoid it and face bigger problems later.

I learnt it the hard way, but I'm glad I did.
