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.
BPO Review from Nimmit Shah
Collaborating with Hugo elevated our property management firm's performance. Their support solutions slashed response times by 40% and boosted tenant satisfaction by 30%. Hugo's seamless integration proved instrumental in propelling our business forward, setting new benchmarks in operational excellence.
Customer Support Review from Jambu Subramanian
Their team quickly integrated into our workflow, demonstrating a deep understanding of our business needs. We were impressed by their professionalism and the ease with which they handled complex customer inquiries. Hugo's technical support team showed exceptional problem-solving skills, significantly reducing resolution times for order issues.

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.

Maya Cooper's Review Sourced from Google
Medcare MSO has proven to be far more than just a billing service — they’ve become a true strategic ally. Their data-driven insights identified underpayments from payers, resulting in substantial revenue recovery. Thanks to their automation tools, our team saves hours every week, and they continually seek opportunities to enhance our workflows.
Daniel Smith's Review Sourced from Google
Claim delays were disrupting cash flow, but Medcare MSO implemented a pre-billing audit process that catches errors before submission. Automated eligibility checks have reduced patient billing disputes. Their responsiveness is unmatched, and patient satisfaction with billing has improved noticeably.
Nora Jade's Review Sourced from Google
In behavioral health, billing is complex, but Medcare MSO adapted to our needs instead of forcing us into a generic process. Denials have dropped by more than 50%, telehealth billing is smooth, and revenue is predictable. Their guidance on documentation has improved compliance and reduced back-and-forth between providers and billing.

Courtney Miller's Review Sourced from Google
I am the clinical director for a community-based outpatient mental health counseling center. I also oversee the agency's business operations. Our agency has struggled in past years with finding a billing vendor and lost significant revenue during that time. From the beginning of our relationship with Swagpro (2023), we have had a significant increase in billing efficiency. The Swagpro team has provided exceptional service, consistently even when they have had internal transitions. They are very responsive to any questions, typically in less than 24 hours, with friendly and knowledgeable team members. I, as an administrator who is responsible for overseeing the agency's financial sustainability, highly recommend Swagpro for medical billing services!
Amanda Austin-Mafilika's Review Sourced from Google
I have worked with Swagpro as my billing team for my psychotherapy practice and they are always on top of things. They have always handled my billing issues with courtesy, swiftness, and professionalism. I would definitely recommend!
Megan Matulka's Review Sourced from Google
Swagpro has been a game changer and business saver for me. All my questions and concerns were promptly answered. I was hesitant to use a billing service due to a couple of other contracting experiences, but they have been able to fix everything without adding stress to me. Praveen Potti and his team listen, validate, and are extremely knowledgeable about billing services across medical AND mental health services. I cannot recommend them enough!

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.
