Just an idea:
Some kind of platform to crowdsource connector building, and match this with developers willing to build it.
Lets say 3-4 companies have a need for a connector, but it's not urgent enough for Airbyte to build it, and the companies don't have the developer resources to do it themselves. Then this platform could match companies in need with developers who could offer a price estimate, and then crowdsource the creation of the connector, which would subsequently be open sourced .
Think this could offer both the cheapest way for companies to make connectors happen, and expand the value of the entire Airbyte ecosystem
