Which should you pick?

The two programs are not directly comparable on dollar value. Google accepts a wider range of funding stages, while Customer.io is more targeted. Note that only Customer.io is fully verified against its official page; double-check the other before relying on it. If you qualify for both, there is usually no reason not to apply to both; the programs are independent.
