Most companies fail to scale because their GTM systems break before the business does.

At Harochi, we design GTM Infrastructure: modular systems that unify CRM, enrichment, outbound, inbound, and reporting so revenue teams run on clarity instead of chaos.

Our work replaces fragmented campaigns with enterprise-grade infrastructure that:
• Aligns CRM data with how the business actually operates
• Automates enrichment, scoring, and lead routing
• Connects outbound + inbound so nothing slips through
• Creates executive dashboards that guide decisions in real time

This isn’t lead gen. It’s infrastructure. And once you’ve seen intelligent systems that never stop improving, traditional methods won't cut it anymore.

At 31, running a company with two kids, I failed my driving test.

Last winter, we moved out to the countryside about an hour from Berlin, and I actually needed to drive.

My New York license meant nothing here... so I had to start from scratch. Had to learn how to drive on German roads, driving a stickshift, in German. 

Before I could begin my practical lessons, I had to take a theory test. Took like 3 months to study and pass. 

That's when the fun began: 3-hour lessons twice a week with a 70-year-old instructor who yelled at me like I was 16.

I endured this for 6+ months and then I failed the exam anyway.

I've grown harochi from nothing, managed payroll during tight months, and put out client fires while on vacation. 

But sitting in that car getting screamed at in German like a child? 

That almost destroyed me. 

It hit my ego in a way that I hadn't expected. 

I knew how far I'd come since I was 16 and felt like I was being stripped of all the progress I made. 

There was no getting around it though. No n8n workflow or Clay table could save me. 

The same lesson applies to building harochi: some things just take longer than you want them to.

And the things that are worth doing are worth doing manually first. 

In case you're wondering, I passed on the second try.

Below is actual footage of me driving in the countryside of Germany.

If my life had stayed on its high school trajectory, I'd probably still be in my hometown working somewhere I hated.

Landscaping. Cleaning pools. The hardware store or the pizza place. 

I failed at all of those jobs and was running out of options. 

My biggest fear was getting stuck there, but the odds were not in my favor. 

After college, I kept pushing for "more" without knowing what it actually meant.

A job in tech. 

A life in a new country. 

A career that actually satisfied me.

7 years in, I started harochi, and for the first time, I no longer had the urge to change things up. 

2.5 years later, and I still just want to build this. 

Every decision, every failure, every win is mine. 

I'm addicted.

If you've spent your whole life feeling like you're supposed to want something else, maybe the problem isn't that you haven't found it yet.

Maybe it's that you haven't built it.

I miss what LinkedIn used to be...

It was a place where I could hear from founders/executives/salespeople about their business journeys

Tales about eating ramen to survive fundraising, IPOs, M&A, etc.

I am so tired of seeing posts about: 
- violent conflicts
- social causes
- politics
- non-business-related legislation

So you know what I did?

I used Claude Code to build a Chrome extension that blocks everything that I don't want to see. 

This is the age of personal software. 

One day you have an idea and 15 minutes later, you have your own tool that solves a problem. 

Very excited about getting to enjoy my LinkedIn feed again

I wasn't included in OpenAI's recent campaign, but here is some inspiration for the next one in case they decide to ask me

One summer when I was a kid, we got free groceries every week from a local elementary school in the town over. 

My mom was driving a school bus and summers could be especially hard if she couldn't find extra work. 

I still remember the taste of the off-brand Oreos. 

I'd often ask my mom if we were going to be okay money-wise. After all, we were on Section 8 housing and there was no real reason to be optimistic that our circumstances would change.

But she always said yes and never let on that she had doubts.  

There have been months at harochi where the bank account was looking like I might have to find a job.

But financial uncertainty is nothing new to me.

Growing up with little money instilled in me a high tolerance for financial pain. 

I don't recommend it as a business strategy, but when you've watched your mom figure it out with less, you develop this stubborn belief that things will all be alright. 

That's why I kept pushing to close new business and learning Clay when I had few clients and was barely bringing in enough money to pay rent. 

My mom always said we'd be okay. 

Now it's my chance to prove her right.

Founder & Lead software engineer

I'm leading a software development agency focused on fast iterations. Most of our clients are shipping more features, responding faster to support tickets, and have accelerated growth because of us.

We focused on HealthCare a lot lately due to the accelerated digitalization in this industry. I am a strong believer that we can make healthcare more technically advanced via pure software. 

In terms of technologies, our previous projects involved Ruby on Rails, React, React Native, Scala, Java, Kubernetes, GCP, AWS (ECS, RDS, AKS), Stripe Connect, HIPAA compliance.

Some of our previous clients: 
- Spotify
- Colgate
- Go4Ellis (incl. HIPAA compliance)
- KindBody (+1 HIPAA)
- NXT Sports
- Noom (Healthcare)
- Mochila Fulfillment
- 3Step
- Mylk Guys (YCombinator)
- NLV Productions
- SH Technologies
- One Step Software (Techstars)
- Ergodic Labs
- Med Prep
- Testing Psych
- Abundance Digital
- Tookitaki

I upgraded to a Standing Desk half a year ago! Worth it? Not really - I find I very rarely use it, and recently just thought about it... We tend to stick to what we're comfortable with, to what we are used to. It's hard to get into a new habit. But once it becomes a habit, it's almost like second nature. In 2026, I plan to use it more often.

Are you behind on your Stripe API upgrades? Be careful! Stripe is sunsetting some very important and widely used features.

Stripe::Charges, Stripe::Sources are being deprecated and replaced with the more modern equivalent, the Stripe::PaymentIntents and Stripe::PaymentMethods. While you can still use them, you should plan to upgrade your integrations to avoid imposed deadlines during your busiest season...

In fact, one of my long-term clients started contracting us for a challenging Stripe Connect upgrade, back in the days when Stripe rolled out mandatory Know-Your-Customer (KYC) flows. 

To learn more, keep an eye on the Stripe Change Log: https://lnkd.in/dBm7PKvf

How do we work remotely as a team? What tools to do we use? Let me break it down to you.

- Communication: Slack
- Email: GSuite
- Meetings: Google Meet
- Project Management: Trello - very simple and clean. For more complex projects - JIRA
- Code Editor: Windsurf

That's it - nothing fancy, nothing complex. This is our "productivity" stack. Next, it's up to the individual to figure out what works for them. We don't want to force anyone into using anything that they aren't excited about.

In B2B sales, I learned a valuable lesson: it's easy to focus on getting new customers, but super hard to get them to sign up. However, it's hard to focus on existing (or past) customers, but super easy to get them to sign.

Learning from others' mistakes! Here's another example of failures in marketing that will lead to bad outcomes.

I got a cold email from a company selling cybersecurity services. I clicked on their website, and I got this pop-up.

I get that sometimes marketing emails don't go through strong security checks, but you can imagine how a lead would react if you send such emails.

Are you rich when you make 25x your annual spending? Is that the "golden ratio" of financial independence?

Careful - we re getting replaces with cached code written by AI - so all our code will have the same bugs and issues that we will have to fix… that would be a cool service businss idea: bug fixes for your AI agentic coder

Cute how devs think they’re gaming the system with $200/month for unlimited Claude Code. ”Oh, I’m burning $2K in tokens with 6 Claude Codes before breakfast!”

Buddy, you’re not burning tokens. You’re burning markup.

I wired Claude Code into a dedicated vLLM to see what’s really under the hood. Six hours of pure coding and debugging later:

- 47M prompt tokens
- 45M prefix-cache hits
- 96.39% cache hit rate (token-weighted)
- Actual compute: 1.3M prefill + 300K generation tokens

That’s not GPUs working hard. That’s a cache with delusions of grandeur.

Anthropic’s “subsidized” coding plan isn’t subsidized; it’s a cache lottery. When they serve you a well-quantized Haiku/Opus hybrid that’s 96% memorized boilerplate, the marginal cost rounds to zero. The limits are fake scarcity. The $100 and $200 tiers are merely psychological anchors.

You’re not paying for compute. You’re paying for the feeling of unlimited power while they throttle you at 5 hours/week limits to protect GPU margins.

Agentic coding is a brilliant pricing hack. Just don’t confuse it with actual token economics 🤡

Make sure you own your AI. AI in the cloud is not aligned with you; it’s aligned with the company that owns it.

Here's a great hack I naturally learned that improved my sales skills:

Whenever you get a cold email, cold LinkedIn message, or even a cold call, answer and be receptive - be the buyer!

I'm almost always doing this, just to see how the best salespeople perform. If I forget about them, do they follow up? How many times? If I simply forgot to sign the papers, how do they gently ask me to sign?

I'll give you an example: I get called a few times per quarter from mobile carriers that are trying to sell me their phone services, like SMS, voice, and internet. I almost immediately say:

- I'm not interested - I already have an unlimited cheap subscription, thanks! 

However, last time I got a call, I asked them to tell me more, and asked:

- How are you better than this other subscrption I have?

Next time I send a message regarding custom software development work, I'll understand that most people like where they are at and don't want to change their teams. However, if you approach the conversation from their angle, you'll find that if you can tell them something that they don't know already, you might at least have a small conversation.

Doing this will make you more empathetic to your next clients, and you'll learn faster what works, and what doesn't work in sales.

Not to mention you'll see how easy it is to "slip" through the funnel 😆!
