YelloWhistleAvis 

I have to give YelloWhistle 4 stars only because I didn’t see the ROAS i was expecting. However they are a great brand and i would work with them again after I create more content. Ana I love her she’s AWESOME. My biggest fear was over spending on the ads and she made sure that was not my experience. She’s the sweetest. She was extremely honest and conservative with AD spend. 10 out of 10 for Ana!

After moving to Shopify, I realized I was not growing beyond my existing customer base and needed to do something different. That is when I found Yellow Whistle.

In just three months using their Meta advertising program, we achieved 592% revenue growth, while also improving our average order value and website conversion rate. Yellow Whistle helped put my brand in front of the right audience and pushed me outside my comfort zone in the best way.

My coach Anna, especially helped guide me through the process with patience and clear direction. I see my Meta ad budget and my Yellow Whistle fee as rent for my storefront, and it is paying off.

I'm a small artist brand and I'm really great at creating products, I'm at a total loss when it comes to marketing and branding. Yellow Whistle was crucial at helping me gain confidence in learning advertisement styles and working with me to make marketing still feel on brand. Highly recommend!

We love working with Yellowhistle! They are incredibly knowledgeable, helpful & so quick to respond. I would be so lost advertising on Meta Ads if it wasn’t for them!

Yellowhistle literally changed the trajectory of my business! They were able to quadruple my sales within the first 90 days! Annie is amazing! She’s very helpful! The entire team is great!

Working with Yellow Whistle has been one of the best decisions I’ve made for my business. In just three months, my brand has grown in ways I thought would take YEARS to accomplish. The transformation has been real.

My ads manager, Thati, is truly incredible. She believes in my brand, understands my mission, and you can feel that she is genuinely rooting for me every step of the way. The entire team has poured into my business with strategy, care, and consistency and the results show it.

I’m beyond grateful for everything they’ve done, and I absolutely plan to stay with them long-term. If you’re looking for a marketing team that actually delivers and truly cares, Yellow Whistle is it.

Words can not describe how great our experience with YelloWhistle has been. I have to be honest, in the past, I've worked with several ad agencies for different businesses and my experience has always been poor. I always felt like just a number to them and there was never personalized care or service... so I was nervous to sign up with another one with our current business but I am I happy we took the leap! My sister, who's my business partner, found YelloWhistle and we agreed to sign up. Since the get go, they were super knowledgeable about meta ads, caring, and communicative. It has been a night and day difference with YelloWhistle comapred to the other ad agencies. We chose to do the "Done with You" program with them and it has been incredible to work along side of them and to learn how it all works as well. We got assigned to Kai as our coach and she has literally changed our business financially and it has only been 3 months! I cannot recommend Kai enough and it's such a blessing that YelloWhistle has built such an amazing team of knowledgeable people. If you're on the fence, hire them! But there is one thing I want to mention, don't expect any magically marketing pills (for lack of a better phrase), you still need to be the creative mind behind your business and think of clever ads that will convert in your specific industry. The good news is that YelloWhistle is there to help you brainstorm and idea generate too, and many times there ideas are better than yours but YOU as the business owner needs to be proactive since this is YOUR industry to own. When those two things align, your ideas and YelloWhistle's ideas, that's when beautiful things begin to happen. So with that all said, I dare you to hire YelloWhistle.. it might just change your life :)

So happy I started working with YelloWhistle. In the past 6 months my monthly sales have tripled, and new first-time customers are literally pouring in around the clock. My coach Ana is incredibly helpful, very available, and has helped me increase my knowledge by leaps and bounds. Really glad I took the step to working with them, it has truly changed my business.

Do not fall for their instagram ads.
This was by far the agency that has delivered the worst results. By month four, our sales were actually worse than when we started and I took out an $18k loan to pay for their services. Worst mistake ever.

They sell you on the ads and sales call with: “You won’t have to rely on organic sales anymore.” That person reassured us, overpromised… and then disappeared. We never heard from her again.

From that point forward, Our account manager was polite but inexperienced, and the actual media buyer only got on a call once. Pretty much forced cause they realized how annoyed I was by now with their results.

Even more concerning: they never asked about our cost of goods, margins, or LTV. How can any serious agency run paid campaigns without that information? All they wanted was our target CPA and ROAS, but never dug deeper into whether those numbers were even realistic or how to improve them.

The results spoke for themselves: declining sales and increased stress on our end as we had to rely on organic sales and promotions just to cover the gap their ads left behind.

We ended their services early! 2 weeks before our contract was even up just to stop wasting more time and money.

If I could save one business owner from going through what I did, it would be this: don’t be fooled by their Instagram ads or polished promises. This agency is all talk, no execution; you’ll just end up stressed, disappointed, and paying for “stability” instead of growth (and -$18k)

I've been with the company for about 6 months and I have had GREAT Results! YelloWhistle is very consistent and very knowledgeable. They have helped me to understand the process and have been more than willing to thoroughly answer any questions that I have. I have seen a steady increase in sales at a minimum of 10K per month. Most recently I reached over $20k in one month. I am almost to my 2nd goal in just 6 months. Now I have to work on setting a new goal which I am sure I will exceed. If you are looking for a GREAT advertising company that will help to take your business to the next level, this is the BEST company for the job!

They were professional and nice, but it didn't work out for us. It's great seeing their positive reviews, but from our experience, we regretfully spent $18k for 3 month contract and that doesn't include separate daily ad spend. We had weekly meetings with account rep, but it should have been with the media/ad buyer who is more knowledgeable. Sounds like others also spent the same as us with no results. Just want to put this out there so you can research options carefully. We also went with them due to the facebook ads.

We really enjoyed working with our account manager Ana and YelloWhistle! Our sales have grown exponentially after utilizing their programs and we have since learned how to manage our ads ourselves with the guidance of Ana. Would definitely recommend!

I had tried social media ads in the past, but didn't understand it and thought I would give YellowWhistle a shot after seeing their ads on social media and taking a free introduction call. They were in my budget and I liked that they would be teaching me how to run ads so that I could learn on my own. By month 2 of working with yellowwhistle, my sales increased by almost 500%! 10/10 recommend.

I cannot recommend YelloWhistle enough! As an e-commerce business owner, I had been struggling to grow my online presence and convert traffic into sales. After partnering with YelloWhistle, everything changed.

From the beginning, their team took the time to understand my brand, target audience, and goals. They crafted a tailored marketing strategy that included SEO optimization, ads & social media campaigns. Within just a few weeks, I started seeing a significant uptick in website traffic and conversions.

Thanks to their efforts, my sales have increased dramatically, and my brand visibility has never been stronger. They were communicative, proactive, and always willing to adjust tactics to get the best results.

If you're looking for a professional, results-driven marketing company to take your business to the next level, look no further than YelloWhistle. They truly deliver.

This year my goal has been to grow and scale my business and I knew that a proper ad strategy was needed to help make this happen. I have never run ads before (my business is 10 years old) and my marketing strategy has consisted of social media posting, live events, and word of mouth. I took a big leap to work with YelloWhistle and have learned so much! In the last three months, my online sales have more than tripled. I continue to see growth in traffic and revenue. Huge thanks to Kai, who has been my coach. Kai is kind, thoughtful, and knowledgable. It feels like she has my back. YelloWhistle continues to provide knowledge and guidance so that I can continue to build my business.

Overall, it has been a good experience. There is a lot to learn and sometimes a little overwhelming. Having more things on paper (outlines, steps, etc.. ) would be easier for me to learn, but I'm sure plenty of people love watching a video and learning that way, just not me. It would have been better for me to do this when my business wasn't so busy since juggling it all has been difficult. Kai has been great and utilizing the skool classes has been helpful on top of the coaching meetings. While I gave myself high goals (that have not been met, yet) I do see general growth in my web sales, website visits, etc... With 1 month left, I'm still hoping to see some amazing results! Thank-you, YelloWhistile!

I began YelloWhistle in February 2025 after launching my brand Glimmers in November 2025. I was only making anywhere from $200-400 a month, mostly from people that I knew. I joined the Done With You program and my coach, Ana, has been great! She's knowledgable and I appreciate her timely and thorough responses when I have questions about my accounts. After finishing the 90-day program, I just hit my first $3000 month and have sold over 70 orders, selling a $15 product. I know this is just the beginning and I am very excited to continue my work with YelloWhistle and continue to scale my account! I know it can be intimidating and uncertain if a company will live up to what its promises, and from firsthand experience, they are honest, genuine, and really do whatever they can to help! I really do recommend them for anyone seeking support!

I signed up with Yellow Whistle to learn Facebook ads, based on their promise of hands-on support and expert guidance. Unfortunately, my experience was completely unprofessional and frustrating.

They missed multiple scheduled appointments without informing me, and the person assigned to teach me disappeared for days in the middle of the program. I was left with no direction or support, completely hanging in the middle of the process.

When I reached out to reclaim the missed time or get an explanation, I was completely ignored. After the program’s time limit expired, they kicked me out of their platform without warning. Now, my emails to them are bouncing back, and I have no way to contact anyone.

I spent money and time trusting that Yellow Whistle would deliver what they promised — instead, I got zero value, no accountability, and no follow-through. I would not recommend them to anyone looking for reliable service or proper education in digital advertising.

YelloWhistle has literally been a Godsend. As a busy business owner, managing my own marketing was a hassle. Furthermore, Meta ads and analytics have been quite complex and ever changing. My business was already doing $50k months through organic marketing and ads via TikTok. However, since alot of my target audience is on Meta, I knew the Meta ads would take us to new heights. I just needed someone who knew what they were doing to streamline the process. Plus, since I work in the Holistic Health Industry, I needed someone who knew how to work around the red tape that plagues marketing and advertising in this space. I seen a business owner who I’m familiar with that also works in my industry give YelloWhistle a high recommendation. Since I know this person is very honest and blunt, I quickly booked a call. Oksana was such an awesome business advisor. She was very patient, genuine, and non pushy. She explained clearly what they offered and let me take some time to think it over.

Fast forward, I’ve been with YelloWhistle since Oct 2024 and within two months (1 month of running ads) our sales jumped up to $100k and has sustained that every month thereafter. Matt and Thatiane have been such amazing people to work with. The customer service is top notch. I don’t have any complaints. They have helped to lighten my burden as a business owner. I highly recommend YelloWhistle and will continue to work with them as well.

Working with Ana has been one of the best decisions I’ve made for my business. I chose the DONE-WITH-ME service so that I could learn as well, i highly recommend choosing that option if you can for the first time you run real ads. In just three months, she helped me nearly double my monthly income through strategic, data-driven ad management that exceeded every expectation. Ana is not only incredibly knowledgeable and skilled in her craft—she’s also a joy to work with: professional, responsive, and genuinely invested in my success. Her ability to understand my brand and translate it into highly effective campaigns was unmatched. I was so impressed by the results and the experience that I immediately chose to continue working with her long-term. If you’re looking for an expert who truly knows what they’re doing and delivers real growth, Ana is the one.
