David Callaghan

I’m a clean energy sales executive and entrepreneur with 12+ years closing multimillion-dollar deals across solar, EV infrastructure, and LED efficiency. I’ve consistently been a top-ranked performer, leveraging AI tools and agents daily to accelerate pipeline management, research, and communications.

In 2023, I founded and grew Hilda Management into an internationally operating artist management and advisory firm, building end-to-end infrastructure from contracts and operations to revenue channels, while recruiting and leading a global artist roster. I also launched Hilda Studio (hildastudio.com) in 2025, delivering branding, web, and marketing solutions as the creative arm of the broader business. Before that, I drove measurable growth at EVgo (including 2020 Site Development Rookie of the Year and 2021 MVP), Hive Lighting (50% revenue growth from $1.2M to $1.8M), Allumia (a $3M+ pipeline and $750K closed in 18 months), and Nextility (closed $6.8M and sourced a record $7.15M account), supported by strong quantitative analysis and CRM-driven execution.
