Paul Steckler
Founder & Senior Partner, Ramp Catalyst
“We worked on leading-edge voice agent technology. They recently built an AI agent with Ph.D.-level research and development skills; the result was a breakthrough for that industry. The quality of their engineers is phenomenal. Their skill sets helped us secure important cutting-edge industry work. We may be selling a start-up that we built with them. We’re expecting a 10x ROI if the sale goes through, which is significant for the minimal resources we put into it.”

CTO at Mount Sinai
“Vention has provided very talented engineers across web UI, mobile, backend APIs, and system designs, to data integrations and beyond. Their staff integrated quickly and were dedicated to the internal teams throughout the relationship, acting as long-term partners in our strategic digital efforts.”

“The account management has been great. Proactively seeking out any issues to be addressed and providing the right people quickly when needed. Project management of their delivery has been less of a direct concern, though they have provided a project manager to oversee our engineering coordination who has worked very well.”
