10 lessons from building an AI company in 2025

Hey there,

If we haven't met yet, I'm Simeon. I run Wellgrow and AI Receptionist, and I've spent this past year deep in the trenches of AI implementation for businesses.

In 2024, I sold my previous business (brick & mortar health and fitness operation). And instead of taking a break like a normal person, I permitted myself to say yes to everything. Every project. Every opportunity. Every experiment.

I dove deep into practical use-cases for artificial intelligence (I’m sure you are tired of hearing the word AI at this point), but 35 custom AI projects later, I learned more about what works, what fails, and what actually matters than I did in years of running my previous company.

This is my brain dump. No pitch. Just the raw lessons from a year of building in AI and what I think matters for business owners heading into 2026.

The Exit and What Came After

After the sale, I thought I'd take time to think. Explore. Figure out what was next.

That lasted about a week.

What actually happened was I threw myself into a new world where I gave into my passion for tech, automation and marketing. That was the verge of AI adoption and I was at awe what you can do with it. I got my hands on as many AI projects as I could.

Some with small businesses. Some with enterprise clients. Some with agencies looking to add AI to their stack.

I wanted to see everything. Touch every use case. Understand where AI actually moves the needle versus where it's just hype.

What I Learned From 35 Custom Projects

Here's the thing nobody tells you about AI implementation.

The technology works. That's not the problem anymore. The models are good. The tools are accessible. You can build impressive stuff in a weekend.

The problem is people.

I spotted resistance from internal teams who felt threatened. I worked with business owners who thought AI would magically do the job without any monitoring. I saw unrealistic expectations crash into reality over and over.

The gap isn't technology. It's education.

For Business Owners: What This Actually Means For You

If you're running a business and thinking about AI, here's what I wish someone had told me:

AI is not a replacement for your team. It's a tool that handles the repetitive stuff so your people can focus on what actually requires a human touch.

It's also not set-it-and-forget-it. Models evolve. Customer needs change. You need someone to monitor and adjust. Whether that's you, your team, or a partner like us.

And most importantly, start with one problem. Not "we need AI." Instead: "We're missing calls after hours" or "Our follow-up is inconsistent" or "We can't keep up with inbound inquiries." Specific problems get specific solutions.

Finding the Use Case That Actually Works

Somewhere in the middle of all this experimentation, I found the thing that kept producing results.

AI receptionists.

It is directly tied to a pain I'd experienced in my previous business. Even with a team of 20+ people handling phones, doing follow-up communication, and being active on social media, I couldn't maintain a consistent standard.

Phones got missed. Follow-ups slipped. Information was inconsistent. And I was paying a fortune for coverage that was never quite enough.

The reality is that AI solves this problem better than humans in most cases. It never sleeps. It never has a bad day. It answers the same way every single time.

We now have over 200 accounts with Wellgrow, which I still can’t believe.

We're working with some of the biggest franchises in the US, specifically in the Men's Health Clinic space. And I'm proud to say that even now, I'm the one answering all the support tickets and taking calls.

Not because I have to. Because I want to stay on the pulse of what's actually happening with our customers, usecases, features, and market headwinds.

The Enterprise Side

Beyond the receptionist work, we've deployed full AI call center solutions. Multiple reps. Live call transfers. High-level operations in the financial and legal sectors.

This is where I see things heading. Not just single AI agents, but entire AI-powered call centers that can handle complex operations at scale.

We've expanded into law, legal, immigration, insurance, solar, real estate, healthcare, gyms, and more. We even have government projects in the pipeline for next year.

The demand is real. And it's growing.

The 10 Lessons

Whether you're building in AI or integrating it into your business, here's what I'd tell you:

1. Educate before you implement. Most of the failed projects I saw came down to misaligned expectations. Take the time to understand what you're getting.

2. This is not set-it-and-forget-it. Models evolve daily. What worked last month might need adjusting tomorrow. Plan for ongoing optimization.

3. Focus on one use case first. AI can do a lot. But you'll get better results solving one problem really well before expanding.

4. Internal resistance is real. Your team might feel threatened. Bring them along early. Show them how AI makes their job easier, not obsolete.

5. The technology is the easy part. Integration, change management, training—that's what takes the real work.

6. Stay close to your customers. I still take support calls. I still answer tickets. The moment you disconnect from your customers, you lose the thread.

7. Underpromise and overdeliver. Overpromising was one of my early mistakes. Set realistic expectations and exceed them.

8. Education is the biggest gap. Both for people building in AI and business owners trying to integrate it. If you don't understand what you're buying, you won't get results.

9. Product-market fit is everything. Once you find what works, double down. Don't get distracted by shiny new use cases.

10. Sleep matters. I spent too many nights doing two-hour sleeps handling tickets across time zones. It's not sustainable. Build systems that let you rest.

For Those of You Already Working With Us

Thank you.

Seriously. Whether you've been with us from the beginning or just started recently, you've been part of building something I genuinely believe in.

Every support ticket, every piece of feedback, every conversation has shaped how we build this product. I read everything. I take it all seriously.

And for those of you who've referred other business owners our way, I'm especially grateful. That trust means more than any marketing campaign ever could.

What's Next

2026 is about focus.

AI voice and chat agents. Refining our product suite. Building more robust case studies. Going enterprise with full AI call center production.

I also want to spend more time on education. Tutorials. Content. Helping business owners understand what's actually possible without the hype.

For me personally, I want to create more space for strategic thinking instead of just executing. We've proven the model works. Now it's about scaling it right.

The YouTube Surprise

One thing I didn't expect: YouTube brought in six figures in revenue this year.

I started sharing what I was learning. Turns out people are hungry for practical AI content that isn't outdated in a week.

The challenge is that technology moves so fast that tactical tutorials become irrelevant quickly. So I try to stay high-level. Focus on principles. The stuff that stays true even when the tools change.

The Honest Truth

This year was stressful. Probably more stressful than running my previous company.

Living in Asia and Europe while serving the US and Canadian markets meant weird hours. Constant context switching. Never fully off.

But it was also one of the most educational years of my life. I touched more use cases, met more business owners, and saw more of what actually works than I could have in a decade of traditional business.

Looking Ahead

I don't know exactly what 2026 will bring. Nobody does. The space is moving too fast to make predictions.

But I'm excited to connect with even more business owners this year. To build meaningful things together. To keep pushing on what's actually possible with AI without the hype and empty promises.

If you're on this list, you're part of that journey. And I'm grateful for it.

Happy New Year. Make it a productive one.
