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.

Dirk Kinley's Review Sourced from Google
I have reviewed the industry in late 2021 both from technical and non-technical viewpoints. The Jumio solution, a platform hosting a full suite of KYC & Identity Verification, AML and more, offers well documented API on github and user support channels. The KYC is consistent and accurate and importantly the solution integrates well with your internal company systems regardless of tech stack.
