126 Steps to Becoming a Successful Entrepreneur:

The Entrepreneurship Fad and the Dark Side of Going Solo

The US Census Bureau reported 32,570,855 small businesses operating across the States. Allegedly, every tenth American runs their own business.

But a follow-up story discloses that 76.2% of businesses that had no employees accounted for merely 4% of SMB sales.

As the memory of the 2008 financial recession fades away and the stories of funded startups crossing the 1 billion dollar mark, both regular workers and college students dream about running a successful business, relieved from the boredom of their corporate job or a life spent in a cubicle while paying off debts and mortgages.

Strategic goals. Tactical objectives.

I take an operational approach to accelerate leadership development and propel business forward.

Quite a good call.

Mario bracketed the issues really quickly and then gave me project suggestions that I could understand. I’m not saying I’m slow, but Mario just has a clear way of expressing things, to the point where I’m going to be able to plug things right into my project. I’m finding that Clarity is becoming a kind of board of directors that helps me make smarter decisions *before* I spend money, instead of after.

Highly helpful!

Mario is a professional that wears several hats on any given occasion. WordPress developer, business advisor, business growth strategist, educator, and content marketing strategist are just some of the areas he has expertise in. He has been highly helpful in helping us better understand our business processes and consequently, improve as a company. Look forward to working with Mario well into the future.

Professional and fast!

Mario is a wordpress magician. From day one his impact on our business was immediate. We run a media platform with intense daily deadlines and 80+ clients to service, and we desperately needed his skill and service to continue to grow. I love Mario–because he has saved and made our company money. He’s professional, fast and I sleep well at night knowing he (via DevriX) is at the controls.

Experienced in many fields!

I worked with Mario for 18 months. He’s experienced in many fields, including SEO and Link Building. This made our working relationship easier. He had realistic expectations and good attitude. I had really good experience working with him and his team at DevriX. I’ve never stepped into their office but just by communicating with the DevriX team members it looks like they have a nice work environment. I can recommend Mario – he’s a very nice client and an employer. Also, if you’re young and ambitious and looking for a mentor I guess that Mario can give you some pretty good tips if you’re around him.

Skillful and innovative.

During my career as a Marketing Manager, I have been in touch with many web design companies and SEO experts from Europe. Noone managed to make a better impression on me than Mario. He is a skillful, innovative, and knowledgeable CEO. His pieces of advice are very professional and show he knows pretty well what he is doing. I recommend him and his agency as a reliable and trustworthy partner.

Density Vice President, Global Sales and Channel

You won't be disappointed.

I can’t say enough positive things about Mario and the teams he has built over the years. He’s attentive to detail, but also cares about/understands the big picture. He pushes hard to hit deadlines, but is also comfortable pushing back when requirements aren’t clear or user stories need further refinement. And, most important, he genuinely cares about the quality of the end software product – both in terms of its performance (speed, UX, overall design) and its impact to your business. Hire Mario, talk with Mario, get coffee with Mario, read Mario’s books – you won’t be disappointed, in any case.

Founder of GoProposal & OverSuite

Sound advice.

I’ve been working with web design firms since the mid-90s. Mario’s firm DevriX is the best I have worked with by a wide margin. Their ability to customize high-performance WordPress sites is exceptional. They bring a spirit of collaboration to their work, as well as taking initiative on the virtual project management. Mario has been responsive and has really taken the time to understand out business model. Some of my best interactions with Mario have nothing to do with pending projects but with big picture issues and strategies we need to be thinking about. He’s offered us candid feedback which I find invaluable. A real pro to work with

Instrumental connection!

Connecting with Mario was instrumental to resolving some pain points with one of my businesses. Having spent a decade as a business executive and a serial entrepreneur, I’m quite confident in the best practices of launching and growing a company. That said, niche expertise across different verticals and segments of operations, management consulting, and delegation that Mario assisted with made a notable difference for our roadmap in 2021. I definitely recommend Mario as a business advisor for service B2B organizations looking for growth or support with business process management. His insights were worth 320x his fees!
