Over promise, under deliver

One star — based solely on the quality of work and unauthorized credit card charges.

I originally chose this company based on their Trustpilot reviews — which now makes me wonder how reliable those were.
First, the facts:
• 30 days after our agreement ended, after assets were turned over and all communication had ceased, my card was charged $6,530 without consent.
• No new work had been done. No explanation was provided.
• The charge is now in VISA arbitration.

Prior to that, I hired them to build a landing page for a flat $2,500 for one month of work. The experience was difficult:
• Repeated misunderstandings and careless errors
• Junior copywriting that required heavy rework
• The CEO seemed overwhelmed and distracted
• Three-day turnaround for each revision
At 30 days, I ended the agreement. The team was professional in handing over assets — but all of the work was ultimately discarded. I’ve had it redone elsewhere for about 1/3 the cost.

During this process, I had unknowingly entered into a “monthly subscription” via Apple Pay small print — triggering a $4,750 charge, followed by the larger $6,530 charge a month later. I had already stopped payment on the card, but they got through.

I also paid $1,300 for market research that bore little resemblance to my actual customers. They resisted my feedback and a month was wasted. Later, after more analysis and research, I was pitched a $14,000 super complex marketing package I didn’t fully understand or feel that I needed it — such as ghostwriting my reels and ebook (I’m already a published author.)

They require full payment upfront — which thankfully, I declined.

It's not like in the US. When I wasn’t satisfied, it turned into a debate, with justification and always the big promise of the next phase.

I told the CEO that after several months and thousands of dollars, I had nothing to show for our efforts — not a single captured email address, no usable marketing asset. He reminded me of a six-minute meditation video they had delivered. Fair enough. I just rewatched it yesterday: the closed captions are riddled with language errors. It’s unusable.

In hindsight, I am responsible for my decision. Nobody put a gun to my head. The deeper my investment became, the harder it was to exit.

The worst part is that I came to really like the team and trusted them implicitly … until they began charging my card without my consent.

The five-month experience was emotionally and financially devastating to me.

Final takeaway: Partnering with Yang Flow was the single worst business decision I’ve made in eight years of running my company.

This is my honest and transparent account, in hopes it helps others.

Since I met Yangflow

Since I met Yangflow, they’ve helped me solve several problems I faced as CEO. From the very beginning, they were open to understanding how my business was positioned in the market and how they could provide solutions to improve that.

More than just understanding the problems I was facing, they proposed real and practical actions, guiding me on how to tackle each challenge and also providing services for tasks I wasn't able to handle. They also offered ongoing consulting, providing both practical and theoretical support whenever I needed it.

The impact was positive from the start. They helped me understand where I was and where I wanted to go, always empowering me to move forward and giving me the information I needed to make informed decisions.

I definitely recommend them. The clarity they provide is exactly what a business needs to move forward!

We interviewed 6 agencies - and chose Yangflow for many reasons...

As the owner of a digital consultancy with hundreds of teammates, we selected Yangflow to work in parallel with our team as we (1) had limited bandwidth [we are always serving our own clients], and (2) I wanted a fresh perspective on an important internal initiative.

In short, Rafa, Jhon, Juliano and Danilo have been nothing short of fantastic. Organized, insightful, efficient, respectful, proactive and smart-as-heck! It's like getting a group of digital surgeons to give you the business treatment you need.

Plus .our entire team really enjoys working with them. Chemistry is oh-so-important to me...and these guys are so great to talk and brainstorm with.

No matter how you look at it, Yangflow is a FIRST CLASS organization and ANY advice or deliverable you get from them is going to be superb.

If you are looking for a partner to help you get your project off the ground - Yangflow is the team to count on.

Yinflow is extraordinary

Yinflow has established itself as an extraordinary company. Being extraordinary is simple but not easy: find great people and put them in the right role; develop tools and processes that make a marked difference to your clients’ success; relentlessly pursue best practices and never stop learning; commit to a work ethic that allows your clients to implicitly trust and value you; and find joy in making the dreams of your clients come true. Rafael took me through a difficult, incredibly constructive journey of taking stock of where I was in product design and where I needed to be, and he helped me make major changes in my team, tools, and work flow. Most importantly, he assigned Maicon to lead our new design and development team. I love Maicon! Our productivity has increased exponentially and we are having fun doing it. With Maicon and his team’s help, we are producing a product that will transform people’s lives and that I am proud of - something, also, truly extraordinary!
