| Singulate | The early Hopin team (#1, #4, #30 are cofounders) are back together to solve the biggest problem they saw in events and marketing at Hopin. They’re building a next gen AI marketing platform called Singulate. Singulate provides the easiest way to do audience segmentation and better relevance-personalization for marketing to individuals at scale —results of up to 10X higher CTRs and 5X response rates. They’re helping marketers (in demand gen, growth, community/events) nurture and convert more pipeline from their events and existing customers - it’s not an AI cold outreach sales tool (although it can do reactivations) but rather a lifecycle growth marketing tool. The best personalization is invisible - this is the future of large-scale communication. Get a demo to see the product. | $2.3M | Pre-Seed | Oct 08, 2024 |  |
