Tell us about Searchflex
Searchflex exists because most ecommerce brands don’t actually know why their growth has stalled. Google has turned into a black box – companies are spending six figures or more, but can’t clearly link that investment to CAC, LTV, or board-level margins. On average, 30–50% of spend leaks away unnoticed. Smart Bidding hides inefficiency, Performance Max erodes margin, and SEO becomes invisible when it’s not tied to profit.
We built Searchflex to change that. We expose those leaks, cut wasted spend, and rebuild search as infrastructure – something that compounds into long-term growth rather than short-term wins. The result is clarity, control, and profit across SEO, Ecommerce SEO, Google Ads, Shopping, Performance Max, CRO, and attribution.
Unlike an agency, we’re a team of embedded search engineers working directly inside ecommerce businesses. Based across the UK, Melbourne, and the Middle East, we plug into your Slack, stay accountable to your numbers, and operate as part of your team. The difference is in the accountability: we’re not chasing vanity metrics, we’re engineering profitable growth that leadership teams can measure and trust.
How did you come up with the idea?
Ecommerce brands have traditionally treated channels like Google, Meta, SEO and CRO as separate pieces – but in reality, they perform best when they’re connected. Every customer journey should be seamless, and every pound of ad spend should be mapped directly to SKU-level margins.
At the same time, we saw a glaring gap in the technical SEO market. Even household-name ecommerce brands were drowning in technical debt without the expertise and accountability to fix it. That disconnect was the spark for Searchflex: to bring performance and technical depth together into one system.

Tell us about your core product or service
We specialise in ecommerce performance, with search as the foundation. At the heart of this is CheckoutOS – our growth infrastructure that unites Google Ads, SEO and CRO into one operating system. It’s not about tweaking a channel or chasing incremental gains. It’s about engineering a system that consistently transforms intent into profit, removes inefficiencies, and creates sustainable, compounding growth.
What excites you most about the ecommerce/search industry?
There’s a recurring narrative that “SEO is dead,” but the truth is that SEO is evolving – and agencies that don’t adapt will be the ones that disappear. What excites us is building resilient systems that thrive through those changes. We don’t chase hacks, loopholes, or short-lived wins. Instead, we’re focused on durable performance architecture: search that compounds results quarter after quarter, no matter how the search landscape or algorithms shift.
What has been the biggest challenge?
When I relocated from the UK to Australia, I had to rebuild everything from scratch – network, reputation, and client base. That was a hard reset, but it forced me to think bigger and prove the model in a brand-new market. It was tough at the time, but it’s been a challenge that’s made every day an interesting challenge.
What’s your number one piece of advice to aspiring entrepreneurs?
Building a business is messy. Things will fail, plans will change, and the outcomes won’t always reflect the effort you’ve put in. The key is not getting attached to expectations – stay unemotional, learn quickly, and move on.
The hard work you put into previous jobs and relationships always pays back later. Those connections and habits make a real difference when it comes to building something of your own.
And don’t forget balance. Growing a business will demand everything from you, but health and exercise are what keep you sharp enough to keep going.
What’s next for Searchflex?
We’ve just secured our biggest client to date that deliver over £100M dollars worldwide – the results we’re already delivering are a clear proof point of what our system can achieve at scale. It’s the perfect project for us.
Over the coming months, we’ll be sharing a full case study that shows exactly how CheckoutOS compounds performance across Ads, SEO, and CRO.
Beyond that, our focus is on scaling what works: embedding deeper into client teams, expanding internationally, and continuing to prove that search, when engineered properly, is the most powerful driver of profitable ecommerce growth.
