Luke Sparey: The Startup Veteran and Numbers Guy Powering sherloc’s Innovation Engine

Luke is the kind of team member every startup dreams of - curious, versatile, and relentlessly hands-on. Whether it’s backend, frontend, devops, or wrangling the numbers, Luke is the person who quietly makes complex systems work. “I like doing a bit of everything,” he says. 

He speaks from deep experience. Luke’s tech journey began at Postcode Anywhere, where he joined as employee #5 and stayed for a decade, helping it grow all the way to a £65 million acquisition. “That was formative,” he says. “We were the first to do international address autocomplete with sub-15ms postcode response times - real high-competition stuff.”

“That’s the beauty of startup life - you’re not just doing what you’re told. You’re constantly figuring things out.” 

CURIOSITY, INNOVATION, AMBITION

“Startups make you think differently. There’s no formula. You have to be inventive, constantly pushing the limits.”

After Postcode Anywhere, Luke caught the startup bug for good. He built his own product but ran into familiar early-stage walls: limited connections, no marketing muscle, and the challenge of attracting investment. 

Still, he was hooked. 

“I had the broad experience, but I wasn’t in a key role. I knew I needed to be somewhere I could shape the product, not just maintain it.”

From there, he joined Moneyhub, initially a B2C financial app that pivoted into a leading open banking API provider powering the likes of Scottish Widows and Legal & General. The company scaled quickly, but Luke missed the early-stage grit. 

“We cannot solve our problems with the same thinking we Used when we created them.”

Enter sherloc. Or more specifically, Karen Rudich, sherloc’s founder. “The minute I spoke to Karen, I knew. She had everything I lacked - sector expertise, connections, credibility. I could build the tech - but to make it work in the real world, I needed a partner like her.”

That meeting rekindled the same energy Luke had felt at Postcode Anywhere. “We’re doing something small but bold. No huge VC cheque, no safety net - just something new, valuable, and needed. That’s the kind of thinking I like.”

At sherloc, Luke’s superpower is simple but vital: “I’m the guy that does the numbers.” Whether it’s forecasting, modelling, or getting under the hood of complex systems, he makes sure sherloc’s data engine runs smoothly.

What drives Luke is a constant desire to innovate. 

“I admire people who push the limits.”

“There’s a comfort in routine, but I’m drawn to people who don’t settle.”

One of his earliest inspirations was the CTO at his first real startup job. “It was a small, innovative company right down the road from where I lived. That CTO changed the way I saw tech - and made me believe in the startup way of thinking. We just clicked.”

He’s also inspired by figures like Roger Penrose, a physicist who rose from a modest background to become one of the world’s greatest scientific minds. “Stories like that - where someone may have been overlooked or underestimated goes on to do something extraordinary - they really resonate with me.”

If Luke could change one thing in the world? Free, abundant energy. “That’s the kind of innovation that changes everything. It would shift how the world works - from resource conflicts to climate crisis.”

And when he’s not behind a screen? You’ll probably find him in Canada, carving down a mountain in Calgary. “I ski a couple of times a year. It’s the place that brings me peace.”
