I began investing in 2005 while still in medical school. In 2007, I started trading on the Brazilian stock exchange. 

By 2008, I was investing in the forex market using automated robots. For many years, I saw good returns with my stock portfolio in Brazil. 

Through day and swing trading with robots in forex, I had excellent years and others not so much; my results were unstable, though I tended to win more than lose. 

In 2020, I started investing in cryptocurrencies with robots, and in 6 months, I turned $32,000 into over $1 million. I stopped trading and exited this market upon identifying the end of that bull market cycle. 

Also in 2020, I began to study macroeconomics in depth, which became part of my analysis process, using fundamentals in my analysis as well and keeping up with new technologies. This is how I identified opportunities in cryptocurrencies, recognizing a time when the macroeconomic scenario was favorable, blockchain was an emerging technology, and then I developed a portfolio strategy that had an edge in selecting cryptocurrencies. 

Nowadays, my strategy is focused on long/short in the US stock market, aiming to buy (long) the best stocks (usually large tech stocks with high growth potential, solid business moat, but also some excellent defensive stocks) or ETFs of the best sectors and sell (short) ETFs that have poor strategies and/or prospects.

Kaicension

You know how visionary startups with groundbreaking ideas still struggle to scale?

They pour resources into branding and marketing, but they’re stuck in a loop of stagnant revenue, diluted messaging, and investor skepticism. The problem isn’t their product—it’s their inability to translate innovation into category leadership.  

At Kaicension, we don’t just “fix” brands—we engineer market dominance. 
As a growth strategy advisor, I work with AI and Tech Startups to build scalable growth engines that fuse emotional storytelling with ruthless data-driven execution. 

Our super power is turning Founders’ visions into unignorable movements that captivate Customers and Investors.  

And we do that by helping them

- Build a brand that’s impossible to ignore and one that customers root for not just buy from, using psychology-driven loyalty loops with messaging that resonates deeply with your audience 

- Replace guesswork with growth loops and systems that attract, retain, and monetize customers at scale without burning through cash.

- Position their startup as a high-potential, low-risk investment with properly craft pitch decks, unit economics, traction metrics and a compelling story. 

- Transform their startup into a category leader by aligning their brand, product, and growth strategy into a unified, unstoppable force.

My Job is to ensure we keep delivering exceptional services to our clients and mapping out strategies truly scale them to the next level.

If you’re currently trying to scale a startup and you are reading this, the LinkedIn algorithm must have brought you here for a reason.

Let’s make this a powerful 2-minute connection.

You’re an ambitious startup founder with a vision that could change the world. But let’s be honest, scaling your startup into a market leader is harder than participating in an Iron Man Challenge.

I'm sure you’ve poured your blood, sweat & tears into your Business. Yet, standing out attracting loyal customers, and securing the funding you need feels like fighting Mike Tyson in a Boxing Ring.

You’ve tried different strategies, maybe even hired experts or put together your own growth team like the Avengers, but the breakthrough you’re looking for hasn't come.  

Deep down, you know there’s a better way to grow. Not just fast, but sustainably. A way to build a brand that customers love, investors chase, and competitors fear.  

Here’s the problem:

1. Your startup has groundbreaking potential, but blending innovation with investor-ready scalability hasn't happened for you yet.  

2. Your brand feels invisible and no matter how much you tweak your messaging, customers still don’t care the way you want them to.

3. Your growth is inconsistent. You’re either burning cash on ads that don’t convert or stuck in a cycle of “good enough” traction that doesn’t excite VCs.

4. Your pitch isn’t landing Yes your startup is special, but VCs keep saying, “Come back when you have more traction.”

But what if you could

- Turn your startup into a category leader that dominates the conversation?

- Build a brand so emotionally compelling that customers beg to be part of your movement?

- Position your startup as investor-ready with metrics and narratives that make VCs compete to fund you?

That’s where Kaicension comes in.

We’re not just another agency, we’re your growth hacking partner.

We will work with you to:

1. Hack your Brand: We’ll craft a brand identity for you that builds moats that which turn your customers into fanatics who defend your brand and make competitors irrelevant.

2. Hack your Growth: Replace guesswork with scalable systems (viral loops, retention engines, and profit-driven campaigns).

3. Hack Your Pitch: transform it from “another SaaS tool” to “the only logical investment” with narratives that align with with Investor psychology and metrics that prove scalability.  

If you’re ready to turn your startup into an unstoppable force, DM me ‘GROWTH’ for a free, no-pitch Audit of Your Biggest Growth Leak.

Dear Founder, If you have not gotten half way to the Goals you set for your business this year this post is for you.


I had something polished to post today, but it felt disconnected.

So I deleted it and asked myself: "How are things really going for Founders right now?"

What's it like for you?


Perhaps you've been pitching Investors since January and still haven't closed a single check?


Perhaps you've been posting on LinkedIn every day for 3 months but still can't get VCs to respond to your DMs?


Perhaps you checked your startup account this morning and saw a number that made your chest tight

Wondering how you'll make payroll next week?


Perhaps you're worried about December,

About how to tell your team again there are no bonuses this year

About going home to family who ask "how's the business?" and you have to fake a smile?


Perhaps you believed so much that 2025 would be your breakthrough year,

But here we are in the final stretch and you're still fighting for survival?


Perhaps you have a toxic Investor who treats you like an employee,

But you can't walk away because you need the money and starting over feels impossible?


How's it really going for you?

Are you tired?

Are you holding it together but barely?

Do you need funding, traction, or just some peace of mind?

What's the one thing you would love to achieve before this year ends?

For me, it's helping 3 more Founders close their first investor check and end this year with momentum instead of exhaustion.


I wonder what it is for you.

But if it's landing that first $50 - 100K check,

The one that would let you breathe and pay yourself and your Team properly.

Also help you Hire that critical role

And start 2026 with actual runway instead of anxiety.

Then I can help you get it.


There's still time for you 

December isn't over.

2025 isn't done with you yet.

But you need to move differently than you've been moving.

You deserve to end this year with a win.

With proof that all the sacrifice wasn't for nothing.


If you believe you do, and you want real help to close out 2024 strong

Send me a DM with any word you want.

Let's talk about getting you funded before the year runs out.

You've worked too hard to finish empty-handed.

Have a lovely weekend.

- M.O.G
