It's grammatically correct, but it's very awkward. Most people would say "We partner with technology companies to introduce their products to new markets in developing countries".

As it's written, it only mentions "a business" (singular) when it likely means multiple businesses. It also uses the word cooperation, which has different connotations than a partnership. Typically, business will say that they "cooperate" with governments, standards bodies, or trade restrictions. For friendly and mutually profitable agreements, they'll use the word "partner" to indicate that both parties benefit.
