Companies that are looking to get acquired don't hold press conferences to announce, "we're now ready to be acquired". They typically build and acquire press wins to get attention until they are a thorn in the side of a market leader who then takes a meeting with them. It's a quiet process, but the initial conversation is almost exclusively, "we're building this for the long term and we plan to be around for a long time".
Just like all the products that promise long or even "lifetime" warranties - for most of these tech startups, they are well aware that lifetime means "OUR" short lifetime as a company and not your lifetime as the consumer.
