Castro

B2B CYBERSECURITY MARKETING EXECUTIVE

I build marketing engines for cybersecurity companies from zero, turning demand generation, product positioning, and brand into measurable pipeline, from Seed through Series C.

Christine Castro
CHIEF MARKETING OFFICER
SCROLL

Visionary marketing leader with a proven track record of building world-class marketing engines for pre-IPO cybersecurity startups — across Seed through Series C. Specializes in accelerating pipeline, establishing category presence, and delivering measurable ROI by unifying demand generation, product marketing, brand, content, and revenue operations into one growth strategy. Deep domain expertise in identity threat intelligence, dark web monitoring, endpoint breach prevention, IAM, and SaaS security, with experience spanning commercial, enterprise, and public sector markets.

Three ways I move the needle

GTM

Demand Gen Engines

Builds full-funnel demand generation from the ground up — pivoting teams from lead gen to pipeline-accountable demand gen inside months, not quarters.

POSITIONING

Category & Product Marketing

Sharpens brand and product positioning so buyers understand why a category, and this company within it, matters right now.

OPERATIONS

Team & Budget Stewardship

Leads and mentors marketing teams up to 20, managing multi-million-dollar budgets with the discipline boards expect at every stage.

Built and ran a national CISO summit series, two years running

From Napa Valley to Newport, RI, I conceived and led HYPR's flagship executive summit series from the ground up — venue, guest list, agenda, and speaker lineup, designed as one seamless experience for a room of CISOs and security leaders. It's the same discipline behind the proprietary conference program that delivered a 1,112% ROI: high-trust gatherings, built to convert relationships into pipeline.
