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.

Michael Muffoletto SVP at LendUS

Recruiting Review from Michael Muffoletto
Global Impact Sourcing was an incredible success for me and my company. I worked for one of the largest mortgage lenders in the nation, and GIS helped us grow much quicker and with high quality new talent joining our teams across the country. They under promised and over delivered, and I could not be happier with their performance. The company is super easy to work with, affordable, and the leadership is extremely knowledgeable! I'd recommend GIS to any company looking to grow, and more importantly, looking to grow with highly talented people!

Kaho Sakemi's Review Sourced from Google
Working at Zventus as a contractor has been one of the most insightful opportunities of my career. The projects I worked on were diverse and impactful, giving me hands-on experience in data analysis, marketing, and cross-functional collaboration. The leadership team is approachable, highly knowledgeable, and genuinely invested in helping you grow. The work culture is collaborative and supportive, making it easy to learn from colleagues and contribute meaningfully to company goals. I’ve gained valuable skills, industry knowledge, and professional connections that I hope to maintain with these individuals for years to come.

Harley Chen's Review Sourced from Google
I have just completed my four-month internship as an Associate Consulting Intern at Zventus, and I highly recommend this company as a place to work and intern.As a college student eager to break into the business world, I found Zventus to be an incredible launchpad. It provided me with the opportunity to apply what I’ve learned in school to real-world, client-oriented projects, while also engaging directly with senior management. Most importantly, they truly listen to your ideas and feedback.During my internship, I contributed to a variety of projects including market research, data analysis, marketing resource creation, business strategy, financial forecasting, and even project management. This diverse experience has been invaluable in preparing me for my future career.I have now secured an internship with a Fortune 500 company. My experience at Zventus was instrumental in this achievement. Not only was it my first internship in the U.S.—which significantly enhanced my resume—but it also gave me the deep knowledge and practical experience that became the highlight of my interview discussions.Thank you for all the amazing people here, each one of them is absolutely amazing to work with!

Gabriela Saavedra's Review Sourced from Google
I absolutely do not recommend working for this company. They are inefficient. If there is a problem, don't expect them to contact them, as they never show up. It seems like a school project where they never know what happened or who did what, and in the end, it's a collage of incomplete projects. They still want to pay the minimum and expect you to divide your time into three or four different activities. PLEASE DO NOT APPLY. This company is not worth it. They are inept, irresponsible, arrogant, and underpaid.

J B's Review Sourced from Google
They are simply crooks. I told them multiple times to cancel my subscription and they continued to charge my credit card. Over $1000 in stolen charges. Hours on hold with a ridiculous inept customer service system that ran me in circles. I finally had to cancel my credit card. My emails were ignored. Stay away from this company.
