About E4C5
We are a results-driven marketing agency built for growth-stage tech companies.
We bring together strategy, SEO, GEO, CRO, paid search, and the technical expertise to turn growth goals into results.
Our work combines strategy and execution. We don’t believe in spending months planning before putting ideas into the market. We ship quickly, measure what happens, learn from the results, and then use those insights to make the next move smarter. We dig into data, challenge assumptions, test what matters and focus our time and energy on what moves the business forward.
We believe the companies that win are the ones that learn faster, make smarter bets and turn what they learn into action and results.
Our Mission and Values
E4C5 is striving to create a world where the best growth tech companies win in market - not because they outspent the competition, but because they outlearned them.
Iteration Wins
Done and learning beats perfect and waiting every time. We move through our process: test, learn, deliver, and repeat (aka TLDR), which helps us iterate and improve deliverables. The fastest path to the right answer is a real result in the real world, not another round of internal deliberation. Perfection is how good work dies waiting.
Put Outcomes First
We are outcomes oriented and we succeed because of ruthless prioritization. Speed is a weapon and knowing what to skip is a skill. Focus on the outcomes that move the needle, the clients who need us most, and the work worth doing well.
Seek to Understand
We communicate openly, honestly, and often. Before we react, we ask. Whether it’s with clients or our teammates we lead with curiosity, not assumption. When results disappoint or a client asks hard questions, we go to the data, not to the exits. We sit with them in the problem, name what’s happening clearly, and focus on what’s next.
Ego is an Enemy
At E4C5 we own our flaws, name our tendencies, and believe in the ongoing self-work that makes people genuinely excellent. No one is “above” completing any task or helping each other out. Ego closes the loop. It stops you from listening, learning, and growing.
Bet on the Person
We believe in management that makes people reach for more, rather than put people in a box with a ceiling. This cultivates self-starters, rewards ownership, and creates space for people to surprise themselves. We would never bet against the people at this company. If they want it and believe they can do it, so do we.
Founder, E4C5
Luke
Richardson
E4C5 was launched in January 2025 by Luke Richardson, who spent nearly ten years working internally at startups and major companies in SEO, web, conversion optimization, and analytics.
The practitioner
Along the way, he moved from practitioner into leadership roles
But the real turning point in his career came from working both sides of the fence: growth marketing and product management.
Leading an experimentation team taught him something many marketing organizations overlook: ruthless value for effort prioritization.
The middle game
That discipline, borrowed from Agile and product management
became the foundation of how E4C5 operates. Every client engagement runs on the same cadence: weekly stand-ups, monthly deep dive analysis, and a roadmap that is re-prioritized every 30 days. The goal is always to ship something meaningful within a week and land a major milestone within a month, not to produce sprawling plans that go nowhere.
The next position
E4C5 grew into a $100K+ MRR agency entirely through referrals and expansions
driven by a simple observation from Luke's own time on the brand side: too many agencies hand over polished ideation and leave the client to figure out execution. E4C5 was built to close that gap. Clients get a roadmap instead of a glossy slide deck, with dependency mapping, effort estimation, and size of prize already scored, so the conversation is about what to do first, not how to start at all.
The result is a build-measure-learn mindset applied relentlessly. Clients consistently tell E4C5 they've never experienced this brand of outcome-first thinking and prioritization discipline from an agency before. That's our mission: winning by outlearning and out-thinking the competition, not just spending more than them on ads.
Client Results You

“I’d been burned enough times to basically give up on SEO agencies. But Luke and his team are the real deal. They’re helping us stay ahead in an explosively competitive market — across both traditional search and the emerging GEO landscape — and more importantly, they’re turning our wins (200% non-brand traffic growth in 12 months) into what actually matters: conversions and influenced pipeline. Everything is moving at warp speed right now. Having the right partners in your corner has never felt more important”

"We have page one ranking for most of our keywords, and in some cases our AI results are ranking higher than some of Google's cyber security products. As I like to say, we're out ranking Google, on Google!"
