As you are no longer with the company for which the visa was issued, you may not be granted entry to the US. This visa functions like any B1 visa but allows certain employers to bring a specific foreign workers based on the B-1 (in lieu of H-1) visas.
Additionally, at the border, you would be unable to provide the same evidence as was presented to the US consulate which considered, and granted, the visa (e.g., purpose of travel, source of pay, host company letter, employer letter).
While the visa may appear to be valid, attempting to use it may have significant, and far-reaching, repercussions.
