About the Founder
Hello! I'm Sarah. I build and launch AI-native products, help founders take their ideas to market, and help established businesses learn to leverage AI for their next phase of growth. I believe in the power of AI coupled with a human-centric approach.
I founded Campsix in 2012 to help founders go to market, secure funding, and scale — and fourteen years later I'm evolving it into a studio where I build and scale AI-native products alongside founders, and help business owners get AI-savvy. I'm building in public on this journey, sharing my learnings and documenting the process as I grow.
I've spent my career as the person leaders call when they need an experienced operator to drive vision, execution, and results — whether launching something new, navigating high-growth phases, or restructuring for what's next. I've done this within and alongside industry-defining companies like Salesforce, LTK, thisMoment, Moe Assist, Rosy Wellness, Hello Alice, and Female Founder Collective. In 2020 I co-founded Lemon HQ, a seven-figure agency, where my team scaled brands like Brilliant Earth, Ring Concierge, Armani, and Evolus through brand marketing, partnerships, and influencer campaigns.
With 25+ years of experience — building venture-backed startups from $0 to $10M as an executive, and supporting multi-million-dollar brands through my agency — I've built the playbook for repeatable strategies that drive growth and retention. And that playbook now runs on modern AI.
Who I’ve Worked With
My Superpowers
Growth Marketing
I develop and implement end-to-end growth frameworks—integrating paid, organic, outbound (including direct mail), channel partnerships, and product-led initiatives—to drive rapid, data-driven customer acquisition and optimize revenue performance.
Scaling Influence & Content
I define and lead content strategies that drive growth, shape perception, and unlock revenue—activating voices across podcasts, YouTube, Instagram, TikTok, Substack, live events, and educational series. By crafting a unified voice, structure, and storytelling at every touchpoint, I spark authentic engagement and amplify brand lift.
Uncovering Opportunities & Ideas
I have the unique ability to connect the dots and uncover big ideas for businesses who are looking to expand their market footprint. I work alongside founders to reveal meaningful opportunities, industry positioning and strategic moves that maximize impact.
Brand Strategy & Positioning
In a world where anyone can ship a product overnight, brand and experience is the moat. I help founders define their essence, values, and true differentiation, then build the experience around it: from positioning and messaging to the full customer journey — first touch, onboarding, engagement, and retention.
Execution & Leadership
As an effective leader and communicator, I provide hands-on support, working closely with leadership to align strategy, inspire teams, and ensure momentum toward business objectives.
AI Integration & Enablement
I help established businesses become AI-savvy — auditing where AI creates real leverage, then embedding the right tools into how teams plan, execute, and scale. Practical adoption, not hype.
Operational Optimization
I help businesses at all stages assess their business models, strategies, operations, AI tools and teams to maximize profitability and scale. I analyze systems, processes, tools against KPIs to drive success.
Revenue Enablement
Campsix helps companies tie brand and go-to-market directly to revenue. I do this by shaping offers, prioritizing channels, and building marketing programs that support pipeline, conversion, and growth—alongside decisions around pricing, packaging, and new revenue opportunities.
Go-to-Market
I craft end-to-end GTM playbooks—aligning product, marketing, and sales—to pinpoint your ideal audience, sharpen messaging, optimize pricing & packaging, and select the right channels to create high-impact launches that convert and build lasting traction.
Building AI-Native Products
I concept and launch AI-native products from zero — turning ideas into real, working products. From idea and validation to build and go-to-market, I move fast with AI at the core, and can handoff MVPs for launch or development.
