About

🚀 Unlock Growth Without Burning Cash or Energy

Too many founders invest time, energy, and money in wasteful tactics that fail to deliver results.

You are probably doing everything you can, but still not seeing progress. The last thing you need is more fluffy campaigns adding fuel to the fire.

I'm Sid from Unlock Growth. For 24 years, I've helped founders and teams break through growth ceilings, without the fluff or waste that so often plagues growth efforts.

I strip things back to first principles. We dig deep into customer insights to uncover what truly drives buying decisions. We sharpen your positioning, craft messaging that sticks, and validate every move with data-backed experiments. We bin the guesswork and random acts of marketing. We focus on repeatable, measurable growth.

That's why accelerators such as Techscaler, Barclays Eagle Labs, Opportunity North East, Digital Boost, and Edinburgh Innovations trust me to mentor their startups.

💥 Highlights from my journey:
• Delivered 37% MoM MRR growth as Head of Marketing at Krotos. I led their expansion and go-to-market of their AI-powered sound software, which is now used by Hollywood studios and content creators worldwide.
• Helped Mindset AI build a marketing engine that supported their £4M raise and contributed 59% of closed revenue.
• Doubled year-on-year revenues for Flavours Holidays and Lenses in Glasses. My expertise in growth hacking and optimising customer journeys significantly boosted these companies' inbound leads and overall revenue.
• I've worked with major brands like Coca-Cola, Cadbury, NHS, and Unilever, as well as leaders from FanDuel, Meta, PayPal, Klarna, and Ogilvy.

💡 You can access my expertise in flexible roles as a Strategic Growth Partner, Fractional CMO, or Mentor. I'm here to help you build a system for scalable, sustainable growth.
