In the heart of the Waikato, a quiet revolution is brewing—not in a lab, but in the home of two founders who believe the future of food isn’t found in new additives. It is found in a better system. Vineet and Vibhah Shiriwastow, the duo behind Four Leaves Co Ltd, are transitioning from the high-pressure world of infrastructure to the delicate science of functional nutrition with their first platform: LULLAA™ NZSmartMilk™.
“We built and operated a separate business in infrastructure and workforce development,” says Vineet. That programme produced measurable outcomes, but more importantly, it established a philosophy. “Working closely with government, councils, and people rebuilding their lives teaches discipline, patience, and responsibility,” he says. “You learn very quickly that systems must work in the real world, not just on paper. That system’s mindset directly informs how we now build food.”
This systems-first lens now sits at the core of Four Leaves Co Ltd. Rather than chasing functional food trends or adding ingredient stacks to existing products, the founders focused on structural design from the ground up.
“Our belief is simple: if you design the underlying structure properly, the product doesn’t need to shout. It just works,” Vineet explains.
LULLAA™ NZSmartMilk™ emerged not from a lab brief but from a family tradition, and a moment of dissatisfaction with what was available on shelves.
“The inspiration is deeply personal,” says cofounder Vibhah. “In my family, a milk-based wellness drink has been prepared for four generations.” But when they became parents, she says, the modern options didn’t feel right. “We couldn’t find anything on the shelf that felt appropriate for everyday family use. Many products felt over-processed, overly engineered, or nutritionally aggressive.”
That prompted a different starting question. “Instead of asking ‘what ingredient should we add?’, we asked: What if the problem is how nutrition is held together in the first place?” she says. “That question led to LULLAA™.”
“Through our process, ingredients are kept suspended and stable in their optimal state, rather than being forced together with gums or stabilisers,” Vineet notes.
The goal, he says, is functional performance without the usual trade-offs in taste, texture, or label complexity. “That allows us to deliver functional nutrition in milk that still looks, pours, and tastes like milk without relying on stabilisers, preservatives, or heavy processing.”
The product is also designed in response to what the founders see as growing consumer fatigue with fragmented wellness routines.
“Today, people are expected to manage nutrition through fragmentation — protein powders, collagen sachets, mineral tablets, probiotics, botanicals, all separate,” says Vineet. “We designed LULLAA™ to reduce that burden. Not by piling ingredients together, but by designing a system where they can coexist naturally in a familiar daily format.”
He is careful about how he frames the benefit. “It’s about reducing friction, not increasing claims.”
That thinking also extends to how they view broader industry direction. “Globally, we’re seeing a correction in functional food,” he says.
“Consumers are more label-literate, more sceptical of ultra-processed solutions, and more interested in how food is designed, not just what’s listed.”
“Innovation is moving away from louder marketing and toward quieter architecture,” he adds. “That’s where we believe New Zealand can lead.”
Building a “slower, cleaner” product hasn’t been without its hurdles. The founders have bootstrapped the venture, facing the reality of a difficult funding landscape in New Zealand.
The company is currently in the pilot phase and preparing for scale, with rollout plans intentionally shaped around environment rather than speed. “We are currently finalising a New Zealand launch pathway, and a world-first regional pilot in a Tier-1 Pacific wellness and hospitality environment,” Vineet says. “That location was chosen very deliberately not for scale, but because the leadership there understands long-term guest wellbeing and operational simplicity.”
For the founding pair, the venture is also structured around complementary roles. “Vibhah leads product thinking, emotional strategy, and public narrative,” says Vineet. “I focus on systems architecture, execution, and operational scale. That separation allows us to build with both care and discipline.”
When asked about the hardest part of the journey so far, his answer is immediate. “The hardest part hasn’t been failure, it’s been restraint,” he says. “Choosing to build something slower, cleaner, and more disciplined when faster paths exist requires conviction.”
Their internal filter is deliberately simple. “Every decision was filtered through one question,” he says. “‘Would we give this to our own children every day?’ If the answer was no, we stopped.”
For Vibhah, that lens keeps the work grounded. “It turns product design into a responsibility decision, not a marketing decision,” she says. For her, the ultimate goal isn’t just a successful product—it’s time. “I’ve never worked for money. It’s time,” he reflects. “Every success we have is built on the same vision that we don’t work for ourselves, we work for our next generation”.
