About Mango Media Advisors
Senior-Led. Independent.
Built for Outcomes.

Mango was founded because we kept seeing the same problem everywhere: real money being spent on advertising with no clear line between what was going in and what was coming out. Good technology being run by junior people. Agencies with platform conflicts giving advice that benefited the platform more than the client. We built something different.

Our Mission
"We help brands, marketers, and agencies use programmatic advertising, audience intelligence, data, and AI to make smarter decisions โ€” and connect every media dollar to a real business outcome."

We don't measure success in impressions served. We measure it in revenue generated, customers acquired, costs reduced, and strategic decisions made with confidence. An independent practice with no vendor kickbacks, no conflicts, and senior-level expertise on every account.

๐Ÿ“ˆ
Growing Revenue & Customer Base
Every strategy we build is designed to bring in more of the right customers at a sustainable cost of acquisition.
โšก
Improving Cost-Efficiency
We find where budget is leaking and fix it. Systematically, not by instinct.
๐Ÿ›ก๏ธ
Independent & Conflict-Free
No vendor relationships. No platform kickbacks. Every recommendation is based entirely on what's right for your business.
๐Ÿ“Š
Financial Accountability
We connect every media dollar to a business outcome your CFO can stand behind.

The Performance
Marketing Architect.

Sam is a serial entrepreneur and performance marketing executive who has built his career connecting advertising investment to measurable business outcomes. Before founding Mango, he built and sold two companies โ€” including an advertising network acquired by Weedmaps โ€” which gave him a first-hand understanding of what it takes to grow a business through paid media. Not just the strategy side, but the pressure of every dollar mattering.

His expertise spans programmatic advertising, DSP strategy, business intelligence, AI-driven campaign optimization, and audience curation. He's managed over $50M in media across some of the most complex advertising categories in the industry โ€” cannabis, regulated products, real estate, retail, and hospitality. When marketers ask what to look for when selecting a media strategy consultant, the answer starts here: someone who has actually done the work, managed real budgets, and been accountable to real business outcomes.

The Award-Winning
Creative Strategist.

Rachel is a Clio award-winning creative director and brand strategist who has spent her career turning complex business challenges into creative strategies that actually perform. She's built brands from scratch, launched products in some of the most competitive markets in the country, and created advertising systems that consistently deliver results.

What makes Rachel rare is that she's equally fluent in brand strategy and performance creative โ€” a gap most agencies can't bridge. She started her career at fashion and tech startups before moving into cannabis, where she spent over a decade building some of the most recognized brands in the category.

At Holistic Industries, she led the launch of an entire house of brands โ€” including Garcia Hand Picked (with the Jerry Garcia Estate) and Cannaceutica, a first-of-its-kind pharmaceutical brand backed by a clinical trial. She designed and opened over 20 dispensary retail experiences and built campaigns that repeatedly landed in BDSA and Pioneers top 10 best-selling brand lists.

Alongside her work at Mango, Rachel leads brand strategy and marketing for ultra-luxury real estate in the Hamptons through The Agency โ€” one of the most recognized names in high-end residential real estate. She works directly with agents on personal brand development and go-to-market strategy.

She also built The Agency's in-house creative studio โ€” the first of its kind in real estate โ€” giving agents access to agency-quality creative and brand systems at the individual level. It's a model that's now influencing how the broader industry thinks about agent marketing.

How We Work
The Mango Difference
01
Independent
No preferred platforms, no vendor relationships, no conflicts of interest. Every recommendation is based on what's right for your business โ€” nothing else.
02
AI-Native
We've integrated AI and agentic workflows into everything we do โ€” not as a marketing claim, but as an actual operating model for running smarter campaigns.
03
Senior-Led
When you work with Mango, you work with Sam and Rachel. Not a coordinator who started last quarter.
04
Transparent
You see everything โ€” every metric, every decision, every dollar. No black boxes, no agency markup hidden in a reconciliation you're not allowed to see.
05
No Minimums
We work with budgets starting at $500/month. Enterprise-grade strategy without enterprise requirements.
06
Outcome-Focused
We measure success in revenue, CAC, and business growth. Not impressions served.
