Hugo Reviews & Testimonials
Greg Digneo founder at content guppy
5.0★
B2B Review from Greg Digneo
Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.

Patricia Woolridge Owner at Undisclosed

Amazon Review from Patricia Woolridge
My Amazon vendor problems began when I realized that there were many instances of copyright infringement. Virtual Assistant India provided the perfect VA for the role who has also helped me with ensuring that certifications and product licensing are in place. The last 2 years have seen me, and my Amazon VA grow our sales together.this collaboration actually works!
Chad Fairbanks Chief Executive Officer at Undisclosed
5.0★
Amazon Review from Chad Fairbanks
I had no clue why many of my product listings were flagged or blocked by Amazon. Despite repeated calls with their support team, I could not find a proper answer. Thanks to my Amazon VA, all such escalations were handled with a clear diagnosis to the problem and a quick solution. My VA also helped me with brand registry.
Cheryl Patton Owner at Undisclosed
5.0★
Amazon Review from Cheryl Patton
I had very clear priorities in terms of what an Amazon Ad expert should be able to do. My PPC virtual assistant has performed admirably, creating ad spending limits, choosing most relevant ad types, and identifying redundant campaigns. Today, I have the clarity I sought as a part of my Amazon ad targeting and the expertise I demanded for PPC performance analysis.
