Integrating Klaviyo via Harmonizer

"The Harmonizer team really want to deliver outstanding service. This is the most important thing and it is in line with what the customer wants. I think it is incredibly cool they are developing this amazing integration platform. Where needed, they orchestrate a custom integration and this truly enables all applications to talk to each other as they should. True craftsmanship! In addition, their API solution can solve issues precisely and they offer their service at a good price. I support and am excited about watching them grow their business."

"Various of our core systems didn't talk to each other in the past, and that was a real issue for us at Career Control. We were looking for a flexible tool to fix this issue, and found a perfect match in Harmonizer! We were pleasantly surprised by how fast the integration was up and running. Having the integration in place has enabled us to uncover important actionable insights, and allows me to use our budgets much more effectively. We would highly recommend Harmonizer to others, specifically because of its flexibility and the team's direct, proactive style of communication. The collaboration was excellent. "

"Using Harmonizer, we are exchaning all of our sales and marketing documentation in real-time with our alliance partner Delta Airlines. Harmonizer is a proven, flexible and cost efficient a way of streamlining the collaboration with our alliance partners."

"Partnering with Harmonizer means my team is unburdened where integrations are concerned. The Harmonizer team monitors in real time whether the integrations run as they should and the data is transformed and transferred according to specifications. Should a problem occur, they resolve it immediately - I don't notice the problem and only hear about it afterwards! The Harmonizer team is very fast. I rarely have to call them to log a ticket, because usually they anticipate any issues. In addition, they work on continually improving their platform and adding new functionality. Our interactions are pleasant, friendly, and to-the-point. "

"Ik zou Harmonizer zeker aanbevelen aan andere bedrijven. Niet alleen leveren ze kwaliteit, maar ze doen dit ook op een down-to-earth en efficiënte manier. Ze overdrijven niet met jargon en buzzwords. Het zijn gewoon nuchtere en slimme mensen die goed werkende oplossingen leveren binnen de tijdslimieten. Dit resulteert voor mij in vertrouwen in het team.""

"Interactions with Guido and the Harmonizer team were fantastic straight off the bat. Especially because their approach is highly personal, and they demonstrated a clear understanding of our organisation's needs. I really appreciated that they were solution-oriented. Normally I always think of solutions to problems, and it was great to be unburdened this time. I only had to present my challenge to the Harmonizer team, and they offered a solution. Even when I had doubts and concerns on the Friday before our go-live date, Guido took the time to walk me through the backend solution that Harmonizer provides and reassure me. Truly great customer service!"

"By partnering up with Harmonizer, we are able to offer any integration our customers ask for. This way, our social intranet platform is integrated even better with the organisation of our customers, leading to the best user experience."

"Before we started working with Harmonizer, we had to fill in our customers' data by hand. That was really a lot of work! It took us a lot of time and it was very easy to make mistakes. When we found Harmonizer and started the project, it turned out that our case was more complex and extensive than we initially thought. In order to explain the processes to my client in a simple and understandable way, I got detailed explanations about the technical part from Guido and Thom. They both really take the time to explain things in an understandable way, and I always feel welcome when I have a question."

"Ik ben bijzonder tevreden over hoe Harmonizer het integratieproject tussen ons HR-systeem AFAS en ons recruitment systeem Emply heeft opgezet. Het projectverloop was soepel, flexibel en volledig online beheerd. De overleggen en sessies die we hadden zorgden ervoor dat we de projectdoelen effectief bereikten. Ik was vooral onder de indruk van hoe goed Harmonizer met ons meedacht, het hoge kennisniveau, de creatieve oplossingen en de professionaliteit van het team. Ondanks de veranderende projectomvang op verschillende momenten van het project, ging Harmonizer hier flexibel en positief mee om. Ik zou Harmonizer absoluut aanbevelen aan andere partijen."

"Een van de grootste uitdagingen die Harmonizer voor ons oploste, was het direct binnen een in Yesplan gepland evenement beschikbaar maken van meerdere vrijwilligersdiensten, waarvan de aanmeldmethode per cultuurhuis kan verschillen. Hierdoor kan zowel het evenement als de inplanning van vrijwilligers vanuit één centraal georganiseerd systeem worden aangestuurd. Dit heeft de efficiency voor onze programmeurs én het inplan-gemak voor de vrijwilligers enorm verbeterd. Harmonizer hield ons met regelmatige updates en follow-ups goed op de hoogte van de ontwikkelingen gedurende hele proces, en stuurde bij of gaf advies waar dat nodig was. Wij hebben Harmonizer ervaren als een enthousiast, gedreven en gemotiveerd team, dat met ons mee dacht om zo de best mogelijke oplossingen te bieden. Wij raden Harmonizer dan ook van harte aan als integratiepartner."
