Strategic Communications Advisory For Visionary Founders
O'Brien dedicated her first six months at Opna solely to brand development before focusing on lead generation. In nascent markets like climate tech, establishing trust and credibility through consistent brand application across all touchpoints creates a foundation for all future marketing efforts. Even LinkedIn posts with stronger visual design consistently outperform generic content.
Rather than hiring specialists (copywriters, designers, social media managers), O'Brien advocates for hiring "AI-native generalists" who can operate multiple tools and adapt to evolving responsibilities. This approach creates more resilient teams that can pivot quickly while leveraging AI to handle previously specialized tasks at speed and scale.
O'Brien's shift to unpolished, self-filmed TikTok-style videos significantly outperformed heavily produced content. The key is genuine moments that show real people behind the brand, creating connection over perfection. This approach works particularly well for startups where authenticity naturally aligns with the brand story.
O'Brien emphasizes continuously identifying which 20% of work and team members drive 80% of results. This framework helps marketing leaders allocate resources effectively, reward high performers appropriately, and address underperformance quickly - crucial in resource-constrained startup environments.
Opna takes a "no BS, provocative" stance in the often formal climate tech space, using direct messaging like "if you don't like us, you can find someone else." This contrarian positioning helps cut through noise in crowded markets and attracts aligned customers while repelling poor fits.
Despite heavy AI adoption, O'Brien stresses the importance of maintaining human touchpoints, especially in B2B relationships. She advocates for making marketing as accessible as possible while being mindful of environmental impact - a particular challenge in climate tech where flying to conferences conflicts with company values.
In this episode of The Marketing Front Lines, we speak with Rachael O’Brien, Head of Demand and Brand at Opna, a seed-stage climate tech startup specializing in carbon removal solutions. O’Brien shares her journey from marketing bedroom furniture to building brand and demand generation strategies in the rapidly evolving climate tech space. Through her experience at Opna, she reveals how AI-native marketing teams are restructuring, why authenticity beats polish in content creation, and how climate tech companies must balance growth with genuine environmental impact.
