Jonathan Lo
Fractional Chief Marketing Officer
Hi, I’m Jonathan Lo – a Fractional Chief Marketing Officer.
As principal and founder of Salt Foundry, I help CEOs build custom marketing strategies, lead internal teams, and manage agencies, all without the overhead of a full-time CMO. With over 15 years of experience spanning startups to multi-billion-dollar enterprises, I’ve driven results across the funnel and managed annual ad budgets up to $50 million.
One client said it best:
“Jonathan Lo made an immediate impact as our fractional CMO. From a sales perspective, his work directly influenced pipeline growth and lead quality. He brought clarity and focus to our marketing strategy, introduced structure where we needed it most, and helped us start thinking like a high-performing marketing team.”
I’ve earned a master’s degree in management from Harvard University and certifications from the McKinsey Management Program. Former employers include World Vision and Overstock. Clients include Dwellify, Krosswood Doors, MERGE4 Socks, and Annieglass. In my free time, I’m a teaching assistant for graduate-level courses at Harvard and advise startups in the artificial intelligence, health technology, and consumer luxury goods spaces.
