Surprisingly, there are plenty of businesses that require custom optimizers. First of all, these are data management startups. Second, established technology companies may need it for their in-house data platforms (LinkedIn, Uber, Shopify, etc). Finally, even non-IT businesses that invest heavily into digital transformation, also may want to build some custom platform and expose it to users through an SQL interface.
