Jamie Petterson. Founder of Sales Boutique, an outbound agency that designs and runs cold email, LinkedIn and calling campaigns for B2B companies. Co-founder of Contaktly, website visitor identification software. Based in the UK, working across the UK, the Netherlands, DACH and the US.
The Demand Guy is where the numbers from those two businesses get published. Every benchmark on this site comes from a live system (Smartlead, GetSales, Contaktly, CloudTalk and the reply handling we built ourselves), is anonymised, and comes with the definition of how it was counted.
Where I have an interest I say so: I co-founded Contaktly, and some links on the stack page are affiliate links.
