Co-founder at Caldera Agency, where I developed a prototype-first website offer and delivered client projects.

Greece
Message

At Dialectica, I researched unfamiliar markets, sourced experts, and negotiated fees and engagement terms for consulting and private equity clients. I personally delivered 141 client consultations across 55 projects, representing more than $125,000 in billed revenue.

I co-founded Caldera Agency to serve independent consultants, coaches, and fractional executives with weak online presence. I designed and ran segmented outbound campaigns and created a free custom website prototype offer.

I ran Caldera’s sales process from first contact to signed agreement, set pricing and payment terms, and delivered projects for clients in leadership consulting, finance, human resources, and biosafety. By analyzing the conversion funnel, I found the main drop-off was between the prototype and the sales call.

During my compulsory military service at the Hellenic Army General Staff, I managed the Club staff duty roster and leave schedule and organised official functions. Earlier, as an intern Technical Support Agent at ICAP Outsourcing Solutions, I handled inbound fault calls and resolved connectivity issues.
