We build, buy and grow health businesses.

Better products. Better health.

Meet the businesses How we work

We don't just own them. We get involved.

Ownership without involvement is just a spreadsheet.

Growth Product Technology Operations
Start from a real need

We start with a problem someone actually has, not a category with a nice growth chart.

That means talking to customers and clinicians before the branding, and being willing to abandon an idea that does not survive the first honest conversation.

Respect what already works

When we buy a business, the first job is to understand why it worked without us.

Founders keep what made the thing good. We add the parts that were hard to fund alone — media, technology, supply, systems — and take the admin off their desk.

Inside the business, not above it

Growth, product, technology, distribution and execution. Our people work in the businesses, not on quarterly review calls.

One team supports every brand in the group, which means a lesson learned in one company shows up in the others within a week.

Through REIKHO

Where we cannot operate day to day, we back founders who can — with money and the group behind it.

Strategic investments of up to $3 million, with access to the group's marketing, distribution and clinical capability from day one.

Good people don't always arrive through a job ad.

A senior creative role where the work is judged by whether it performs. You will set the creative direction for every brand in the group and be close enough to the media numbers to know which ideas actually earn their place.

What you will do
  • Set creative direction across group brands
  • Lead concept and production for paid social, video and D2C campaigns
  • Work directly with growth on what to test and what to kill
  • Build a library of creative that keeps performing
What we are looking for
  • Strong D2C and paid media portfolio
  • Comfort making work that is measured, not just admired
  • Ability to art direct and write
  • Care for accuracy in a regulated category
Apply for this role

Every brand in the group has a customer base worth talking to properly. This role owns that conversation end to end: the flows, the segmentation, the calendar and the revenue that comes out of it.

What you will do
  • Build and optimise lifecycle flows across group brands
  • Own email and SMS calendars, segmentation and deliverability
  • Run the testing programme on subject lines, offers and timing
  • Report honestly on retention and lifetime value
What we are looking for
  • Hands-on experience with Klaviyo or similar
  • Genuine interest in retention, not just sends
  • Copy instincts and comfort with data
  • Consumer or health brand experience
Apply for this role

Not a coffee-run job. You will design things that go live, get feedback from people who care about craft, and see the results of your own work in the numbers.

What you will do
  • Produce social, campaign and web assets across brands
  • Adapt and extend brand systems
  • Work alongside the Creative Director on bigger concepts
  • Keep files, templates and assets in order
What we are looking for
  • A portfolio showing taste and range
  • Confidence in Figma and Adobe
  • Curiosity and willingness to redo work
  • Interest in health and consumer brands
Apply for this role

Not the kind of internship where you watch other people do marketing for three months. You will work across Steady Freddy, Nutraviva and SuperFastDiet — thinking about collagen one day, women's health the next, and how to make a men's sexual wellness ad people actually stop scrolling for the day after.

What you will do
  • Come up with TikTok, Instagram and Reels ideas
  • Write hooks, captions, scripts and ad concepts
  • Help brief and coordinate creators and UGC
  • Assist with Meta and TikTok campaigns, Shopify and email
  • Test AI tools and build simple automations
  • Work out why something went viral — or completely bombed
What we are looking for
  • You understand social media and internet culture
  • Curious, full of ideas, happy to test rather than wait for instructions
  • You can write clearly
  • Interest in AI and what it does to marketing
  • No years of experience required. That's the point.
Apply for this role

The person who makes sure we always know where we stand. Reporting, cash, compliance and the financial detail behind four operating businesses in more than one market.

What you will do
  • Own management reporting, budgeting and forecasting
  • Manage cash flow, payables and receivables across entities
  • Keep statutory, tax and audit obligations in order in AU and SG
  • Partner with the operating team on margin, pricing and inventory
  • Improve the systems and controls the group runs on
What we are looking for
  • Qualified accountant with group or multi-entity experience
  • Comfort across both statutory work and commercial decisions
  • Consumer, e-commerce or health experience an advantage
  • Someone who improves a process rather than just running it
Apply for this role

A lot of what makes a group like this work is unglamorous and genuinely important. This role owns that: suppliers, orders, records, systems and the follow-up that stops small things becoming problems.

What you will do
  • Support purchasing, suppliers and logistics coordination
  • Process orders, invoices and records accurately
  • Maintain systems, documentation and reporting
  • Support compliance and quality requirements
  • Be the person who follows things up
What we are looking for
  • Operations or administration experience
  • Genuine care for detail and follow-through
  • Comfort with spreadsheets and new systems
  • Calm across competing priorities
Apply for this role

A small-team role linking management, customer service, commercial activity and our Bathurst warehouse. Around 20 hours a week over four days, roughly 9am–2pm. We're after someone with the right attitude more than a specific background — practical, proactive, and not precious about what's below them.

What you will do
  • Executive and general administrative support
  • Follow-ups, records, documentation and day-to-day priorities
  • Phone-based customer service, including escalations
  • Order, inventory and supplier/purchasing administration
  • Compliance documentation, SOPs and basic accounts
  • Spreadsheets, data and management reporting
What we are looking for
  • Strong attention to detail and a genuine sense of ownership
  • Proactive — sees what needs doing and gets on with it
  • Confident with Excel/Sheets; Xero or Cin7 a plus, not essential
  • Comfortable working independently and as part of a small team
  • EA, office manager, operations or accounts background welcome
Apply for this role

Some of the best hires we have made did not match anything we had advertised. If the work here appeals, start the conversation.

What you will do
  • Tell us what you are good at
  • Tell us where you would like to point it
  • Show us something you made that you are proud of
What we are looking for
  • Curiosity and honest collaboration
  • A bias toward useful work
  • Any discipline across the group
Apply for this role

None of these quite you?

Tell us what you're good at. We read every one.
