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.

Lead Generation Review from Josh Kaye
Complete Scam.Hired them for lead generation.Delivered bogus made up leads.Beat us for 10,000$.Zero return.Avoid at all costs.

Email Marketing Review from Josh Kaye
I recently engaged Cience Lead Generation, paying $10,000 for 250 qualified leads, expecting a professional service and solid prospects. Unfortunately, what I received was far from that. The leads they presented were completely fabricatednone of the individuals or businesses had requested information about my company. In fact, we obtained sworn affidavits from many of these so-called "leads" affirming they had never heard of us or requested any information.This is a blatant scam, and we're now in the process of pursuing legal action against Cience to recover our full payment. If you are considering working with them for lead generation, I strongly urge you to reconsider. Their practices are fraudulent, and you risk losing a significant amount of money without getting anything of value in return. We were misled, and now we're facing the consequences of trusting this company. Dont make the same mistake.

Financial Review from Joel Mantecon
I have worked with with the CIENCE team for over two years already. They provided my company with a team of SDRs that helped us with our lead generation efforts. Overall, we feel satisfied with our investment, as we have seen an increase in sales and organization.

Allan Reyes's Review Sourced from Google
We can’t say enough great things about SalesHive! They helped us build our very first outbound strategy, and it’s been such a game changer for our business. Shoutout to our strategist, Tori—she’s been amazing to work with. She really took the time to understand our goals and guided us every step of the way.It was a little slow to start, but now we’re hitting our weekly goals, and the meeting progress has been fantastic. We’re honestly blown away by how much we’ve grown in such a short time.

Darren Ourth's Review Sourced from Google
This is our first time using a lead generation company and I couldn't be more pleased with the performance of the people at SalesHive. From the initial sales process through onboarding to working with the team to build out the playbook, they walked us through every step of it. Once the program was kicked off the team was great, from the appointment setting to follow up to weekly update meetings, it was a real pleasure to work with them.If you are looking for a lead generation company that really knows there stuff, look no further than SalesHive.

Thaddeus Tague's Review Sourced from Google
They booked us almost 30 meetings in 2 months. That's not normal even for them, but it was exactly what we needed. Shout out to Tykia Jackson, Michael Folling, Melissa, Liam, Madi, and the full team of people that handled our outbound with the specificity and expertise it deserved. Would 100% recommend these guys, and will be returning for more when we can.

Startek is the worst. They provide tech support for other companies... And they never seem to know what is going on. Poorly trained.
