Google ads works for sure, bit costly than LinkedIn that’s also correct but it will give you that missing audience which may not be active on LinkedIn. There are two campaigns that works in Google ads, one is search and another one is pmax, both work mostly on top funnel if your product is high ticket size. And Google search may work for you and give demo related leads if your product is low ticket size. Feel free to connect if you need any help, I am working for an enterprise software company and bringing good pipelines for them
