Tech-led, not tech-focused

Technical marketing that earns technical trust

Hi! I'm Eirilena, a technical and cybersecurity marketer based in Athens, Greece, with 9 years in tech B2B and B2C marketing. I don't write about technical products; I give engineers, developers, and product teams the structure, voice, and strategy to tell their own story.

Portrait of Eirilena Papadopoulou

My manifesto

Technical, developer, or engineer-first storytelling should not be done by marketers. We are here to serve as conduits for the brilliance and deep technical expertise of the people who actually know what they're talking about.

Your user, your buyer, your community does not care about what I have to say; even if I've developed the best marketing strategy in the most polished marketing words. Your ICP values real words, real experiences, and real expertise.

My goal is to provide internal teams and experts with the means to share their story. Technical product storytelling should always come from the people who are building that product, not from the people who market it.

Featured case study

CrowdSec | 2023–2025 | Technical Content Marketing Manager

Repositioning an open source project into an enterprise-ready brand

When I joined CrowdSec, it was a heavily B2C, open source brand: playful visuals, community-first messaging, and a positioning that spoke to individual tinkerers more than the security teams and buyers who could actually adopt it at scale. The product had grown into serious enterprise territory, but the brand didn't follow. I led the repositioning from that consumer-leaning identity to a mature, buyer-focused brand: sharpening the messaging around real threat intelligence and business outcomes, rebuilding the visual identity, and rewriting the core product and solution pages. The new website design also directly addressed long-standing UX and conversion problems, restructuring the journey so that a security buyer could understand the value and act on it.

Before B2C, open source
The old CrowdSec brand: playful, community-first visuals
After Enterprise, buyer-focused
The new CrowdSec brand: mature and buyer-focused

Keeping the community DNA

Moving up-market is where most open source rebrands lose their soul. The hard part here wasn't looking more enterprise; it was doing so without abandoning the community that made CrowdSec what it is. So, I made the community the spine of the story, not a footnote to it. The crowd fuels the threat intelligence, the threat intelligence powers the product, and enterprise adoption feeds the crowd back. It was never community versus enterprise; it was two halves of the same cycle, and the brand had to make that loop obvious.

Cyberbit | 2025–present | Head of Content Marketing & Brand

From nice-to-have training tool to mission-critical readiness platform

Cyberbit was positioned as a platform for upskilling and hyper-realistic cyber range training, making it a rather nice-to-have tool. The reality was bigger. The Cyberbit Readiness platform is a critical piece of SOC operations that builds genuine, measurable readiness. Every part of that story already existed; it just needed the right way to demonstrate it. I'm leading the repositioning from "training you might invest in" to "readiness your SOC depends on," and evolving the identity from a disjointed mix of stiff corporate design and a half-committed attempt at gamified visuals into something mature, fresh, and clean. As with CrowdSec, the new site design is also solving concrete UX and conversion issues rather than just restyling the surface.

Before Stiff, corporate
The old Cyberbit brand: stiff and corporate
After Fresh, clean
The new Cyberbit brand: fresh and clean

From the people who know me

What teammates say

Eirilena lives, breathes, and writes tech like no other content manager I have ever worked with. She also goes beyond content and copyrighting, as for many internal projects we worked together, she has done incredible project management, dealing both with external agencies to deliver on time and our internal product & dev teams, while delivering great pieces of content across multiple formats and channels, with a taste in writing and design.
Nikos Malekos Head of Growth & Demand Generation
Eirilena is a person of passion, ideals, and curiosity. She is collaborative but direct and creative, and she dives into projects with unmatched enthusiasm, no matter how great or small.
Colleen Calahan Head of Product
Eirilena is a true asset to any marketing team. Even in a fully remote environment, she has a rare ability to make work feel more human and meaningful by building genuine connections across the team. She strikes an impressive balance between being exceptionally professional and genuinely fun to work with, which elevates both the culture and the output of the team. Her expertise in content marketing is matched by her deep understanding of the cybersecurity space, including the nuances of different personas across both B2C and B2B environments. She brings a strong growth mindset, paired with the judgment to prioritize effectively and say no when needed. Once Eirilena takes ownership of a project, regardless of its complexity, you can be confident it will be delivered with outstanding quality. She is smart, knowledgeable, and a highly trusted partner to everyone she works with.
Daphne Deiktaki Chief Marketing Officer
I interviewed Eirilena for her role at Snyk and mentoring her afterward was one of the genuine pleasures of my time there. We were building the documentation function in a fast-moving, developer-first environment, and she stepped up to the plate with curiosity and confidence from day one. She's exceptionally smart — she picks things up fast, asks the right questions, and thinks carefully about the reader on the other end of the page. I taught her what I knew, and she ran with all of it. She's also just a joy to work with: warm, funny, and the kind of teammate who makes hard work feel lighter. I'd work with Eirilena again in a heartbeat, and I recommend her without reservation.
Rachel Cheyfitz Deep Tech GTM & Marketing Strategist
Eirilena is such an amazing person to work with! She's extremely knowledgeable in technical writing, content creation, and brand strategy. From the moment she started at CrowdSec, she hit the ground running, creating valuable content that boosted our organic impressions, web traffic, overall messaging, and leads. She has a fantastic ability to tell/create a brand story in a clear way that resonates deeply with the users. I truly admire her work ethic. She is absolutely someone you always want on your team!
Paige Jenkins International Marketing Manager
Talented, creative, hard worker, and incredibly detail-oriented, a true perfection-seeker in everything she delivers. Eirilena is the kind of colleague and Content Manager every team and every company wishes they had. She is the kind of person who you know that if a project is in her hands, you are safe, she will deliver with perfection. Working closely with her, I always knew I could count on her, whether it was strategy, content creation, managing tight deadlines, she consistently delivered work of the highest quality and impact. As a colleague and teammate, she stands out not only for her skills but also for her character. She is trustworthy, collaborative, supportive, honest, and an absolute joy to work with. Definitely, she is one of my highlights of working at CrowdSec.
Olalla Serrano - Piedecasas Intelligence Analyst
I worked with Eirilena during her time as Content Manager at CrowdSec. She is one of the most talented and reliable professionals I have had the chance to collaborate with. Eirilena combines strategic thinking with hands-on execution: she not only created compelling content that resonated with both our technical and business audiences, but also knew how to align it with broader marketing and company goals. Her ability to translate complex cybersecurity topics into engaging and accessible narratives was a real asset to the company. She brought creativity, structure, and a proactive attitude to every project. She managed multiple priorities with ease, met deadlines consistently, and always contributed fresh ideas to improve our campaigns. Beyond her skills, she truly is an amazing person, collaborative, smart, someone you can always count on. Any team looking for a content expert who can drive impact and build strong messaging would be lucky to have her.
Jean Devaux Director of Revenue Marketing
Eirilena is a strong writer/editor/manager who is not only laser focused on the goal of the content and how to measure success, but she also understands how to build and scale a process around how to achieve that goal.
Dylan Rodgers Senior Digital Marketing Manager

My trusted partners in crime

Good web development and design are the alpha and the omega of a good marketing outcome. Without spot-on execution, marketing would fail 8 out of 10 times.

I've been fortunate enough to have two incredible individuals who have been my partners for the better part of my career, executing my ideas, thoughts, and countless iterations to absolute perfection.
