10 lessons for anyone interested in building a business: 

1. You do not need a pioneering business idea/eureka moment. 
2. You do not need genius IQ. It's all about action. 
3. Your ideas, plans, goals, vision etc mean very little. 
4. Find a co-founder. 
5. A sustainable co-founder relationship = healthy competition with the ability to roast each other unapologetically.
6. Make growth plays. Don't coast. 
7. Growth comes from big bets, not polishing the edges. 
8. The arrival fallacy is real; problems never disappear, they just evolve, and become more painful and frequent as the business grows. 
9. Build things with intrinsic value that also reinforce other parts of the business.
10. To reiterate, disciplined action and output is everything. You can't talk, think or feel your way through things - just execute, ship fast, learn and grow.

Felix manages our sales process. 

I genuinely believe his output = typical output of 4-6 human sales reps. 

Why? 

Because we've built an AI-first sales engine. 

Outbound, followup, pre-meeting, post-meeting, proposal creation, nurturing, multi-threading = all handled by AI. 

If AI isn’t deeply embedded across your GTM funnel, you will fall behind. It must become a mission critical priority in 2026.

If you want guidance on how to architect this end-to-end (without duct tape or hype), book a call and we’ll walk you through what AI-powered actually looks like: https://lnkd.in/e3qxXKmr

This is the best outreach I've ever received. 

Three months ago, Dan told me we were on his radar.

He was waiting for the right moment, while making sure the outreach strategy didn’t just meet the standards of an outreach guy, but exceeded them.

Safe to say, mission accomplished.

Sometimes the most unscalable strategies are the most effective.

Scaling content for business owners with AI & systems | Co-Founder @ Thakos

How far would you be willing to go to impress just ONE prospect? 

(Most people will say 2-3 hours max) 

Well, I am completely insane and do EVERYTHING to impress prospects. 

Penn Frank ⚙️ & Felix Frank ⚙️announced they were looking for a marketing manager, so I knew it was time to do something absurd for them. 

Below is easily the best outreach they will ever see and no doubt the best outreach anyone will ever see. 

Going above & beyond for people (who aren't even my clients!) is just what we do. 

🚨🚨 THE BEST OUTREACH OF ALL TIME 🚨🚨:

339 positive replies in 1 week. 
33 calls booked. 

We only launched the client last week. 

Stop sleeping on cold email. 

With the right growth partner, it is undoubtedly the most powerful, scalable, outbound channel.

More insane results from the team! 

We launched with a new client last week. 

We instantly identified Message Market Fit with not 1 but all 8 strategies. 

Nolan - Bravo! And it was your debut campaign at StackOptimise...phenomenal execution. 

This is what happens when you run a Message–Market-Fit Methodology truly optimised for speed-to-value.

No waiting months to see a return.

We’ve split the team into two focused pods.

From age 14 I've worked in Sales...

I started at my family's dry-cleaning business, spending weekends handing out discount vouchers. Over the years that followed, I got promoted to hanging clothes and, eventually, working at the till! 🤣

Following my economics degree at Nottingham, I had the privilege to kick-start my SaaS Sales career at a tech unicorn in Klaviyo. I learnt from some of the best in the game and quickly achieved top-performance as the #1 SDR in EMEA, receiving a few awards and setting a few records along the way 🚀 

Following this I decided to go travelling for a year, immersing myself in cultures across 5 continents. Unsurprisingly, it was a transformative and unforgettable year 🌏

Today you’ll find me at my favourite coffee shops around London, helping home care providers to transform the way care is delivered to older adults using Birdie 🐦

If you know of anyone in the home care industry, want to chat about the world of sales, or just want some coffee shop recommendations, let’s talk! ☕✨

I feel extremely grateful to share that I have been promoted to Senior Account Executive (SMB) at Birdie!

As I write this on a plane back home and reflect on my past 6 months in role, I could easily share the highlights, however, they don’t speak to what underlies the success I have experienced, which is my '𝘸𝘩𝘺'…

In November, a few days before my birthday, I lost my Dadima (my grandmother) unexpectedly. She was the strongest woman I know. She lived a rich life, focussed on providing a better one for our family.

For most of her life she lived in poverty, waking up in the early hours of the morning to make samosas, spending her days selling them on the streets of Uganda.

In 1971, she moved her family to England, alone. Despite building a successful business with my Dadabapa, they caught word of Idi Amin’s plans to expel those of Asian descent, and made the courageous decision to leave before this unfolded the following year. 

Upon arrival, she started again from nothing. She would take 3 buses to work, spending her waking hours every day in a factory, often unable to use the bathroom because her managers would use it as a smoking area. 

In recent years, she provided me with a home after I graduated and moved to London to work at Klaviyo. She did the same again when I joined Birdie.

She refused me paying for anything so I could save and build the financial security that she never had. When I naively chose to pay for something, she would first tell me off in her broken English, and would then proceed to pay me the money back in cash, to the exact penny! 

She taught me what sacrifice means, what hard work really is, and what leading a faithful life looks like. 

I share this story because when people ask me how I have experienced the success I have in my early career, I enthusiastically share the tactics and strategies that have helped me.

However, at the core, my driving force is one that extends beyond myself.

This deep sense of responsibility I feel to fully exhaust myself and provide a better life for the people I love is what drives me forward in the best of ways. 

It is instilled because of the sacrifices every generation before me has made, and my Dadima's journey is the epitome of this, and one worth sharing.

Account Executive @Birdie | Formerly #1 SDR @Klaviyo & Birdie

2025 was transformative for my career, here’s how it went... 

Q1: Got promoted from Senior SDR to AE, took myself off ramp early, and hit 127%

Q2: Continued to learn the ropes in Q2, hit 111%, finishing #2 in our SMB AE team and won a 'Boscar' at our yearly awards ceremony.

Q3: Got promoted into our upper SMB segment, hit 140% and finished as the #1 AE not just in SMB, but at Birdie.

Q4: Closed the largest deals of my career, multiple times. Finished #1 in our SMB team at 135% and closed the 2 largest deals of the year in our team!

2025: 129% to target, closing as the #1 SMB AE ✅ 

On the surface, everything went as well as it could have gone.

What the numbers don’t capture is the consistency of showing up everyday and remaining faithful, the support I’ve had around me through some challenging moments personally, and the trust the team and my managers have put into me.

My following here also grew by over 50% so thank you to those supporting!

If 2026 is anything like 2025, I would be blessed! 😅
