About · Jenn Day

I have spent my career making complicated things make sense.

I work with AI, fintech, Web3, and other technical companies when the business has moved faster than the marketing.

Jenn Day, JDay Creative

I spent twenty years in New York working in financial-services technology, where vague language gets found out quickly.

Since then, the industries have changed. The pattern has not.

The company grows. The story splinters. Sales starts translating. Marketing starts taking requests. Everyone is busy. Nobody is quite steering.

That is where I come in.

Selected Results

Built full-funnel demand systems across fintech and SaaS engagements that contributed to more than $5M in pipeline, reduced CAC by up to 20%, and improved SQL conversion by up to 30%.

Fintech & SaaS Portfolio

Who's This For

Founder-led AI, fintech, Web3, and B2B technology companies that have outgrown improvised marketing leadership.

CEOs entering a raise, launch, expansion, or category shift without a senior marketing lead keeping the story and strategy aligned.

Leadership teams with plenty of marketing activity, but no clear system connecting positioning, demand, sales, and execution.

Companies that need experienced marketing leadership without forcing a full-time executive hire before the business is ready.

When the company has changed and the old marketing logic no longer fits.

Start the Conversation

I am back in Colorado after twenty years in New York. I publish Founder Out Loud and CryptoJazzHands, write fiction, and once carried a sousaphone through Canary Wharf for reasons that seemed sound at the time.
