Founder of BuiltDiffernt | Creating a world where great ideas don't die ahead of being seen by the right person. 📧 Ex-music producer turned cold outreach lunatic. I’ve spent the last year building Bob (our AI GTM manager) to handle the "boring crap" of outbound so you don’t have to. 50k campaigns of data baked into one platform.

The "Lunatic" Who Loves Email: Why We Built BuiltDiffernt

Hey Product Hunt! David here.

I ll be honest, nobody graduates with dreams of starting a cold email agency. When I tell people at parties what I do, I usually get that polite, glazed-over look before they ask if I m the "Nigerian Prince" in their spam folder.

Hey everyone, David here. Founder of BuiltDiffernt.

I appreciate the hype of AI in the past few years has produced many a "useless" product at least, in my world that being the world of sales-tech.
