DatabaseMaker says so · source ↗“Sense is a semantic network, means we have a graph under the hood. Without Neo4j we would never launch such a complex product like Sense so fast! It's just incredibly powerful solution with great documentation and very helpful support. They have a startup program, which makes their product affordable for an early stage company like us.”

DatabaseMaker says so · source ↗“Neo4j Aura was the only option that handled volume without overloading the main database or costing a fortune. With Aura, the database stays idle. Each scan gets its own session, which we delete afterwards, so we don't pay for anything that runs all the time. Nearest-neighbor search and grouping are built in, so we don't have to juggle the data volume in our own infra.”
