From brainstorming to proofreading, I can help with it all.
Your question can be reframed as follows: Can "To create a fancy product..." be used as the subject of a sentence? This really depends on whether "To create a fancy product..." can be used as a noun.
I was recently tutoring a student who has been having difficulty understanding pronouns. We were using the Gettysburg Address as a sample text In this speech, Abraham Lincoln begins three sentences with "It is..."
In the first, the "It" refers to "that we should do this." In the second, "It" refers to "to be dedicated". And in the last, "It" refers to "to be here dedicated..." He clearly used an infinitive form of a verb (to be dedicated) as a noun. If we assume that Abraham Lincoln is an acceptable authority on English grammar and usage, I think we can conclude that "to create a fancy product" can be used as a noun, and therefore can be the subject of the sentence "To create a fancy product will require more effort."
