Hi, we’re Annabelle & Jacob

the founders of Kaia Kini.

Annabelle & Jacob

How we got here

The story so far.

01

The fit problem

Kaia Kini was born from a very real struggle; finding bikinis that actually fit. After four years as a fitness content creator, I had tried just about every swimwear brand out there and kept running into the same problem. Cute bikinis? 100’s of them. Cute bikinis sold separately so you can buy different sizes for top and bottom? Not so much.

As someone who isn’t the same size on top and bottom, settling for a standard bikini set just wasn’t cutting it.

02

Enter Jacob

Enter Jacob. The creative half of the relationship, with a love for fashion and a long-time dream of building a brand. Women’s swimwear wasn’t exactly on his vision board, but after one too many conversations about bad bikini sizing, he found himself deep in the world of fabrics, fits and colour palettes.

03

A family of makers

Growing up, Jacob’s dad ran his own jewellery business, but it didn’t start in a showroom or behind a polished brand. It started much more simply: selling jewellery in his local town, learning as he went, meeting people face to face and building something from nothing.

Over time, that small beginning grew into a real business. He went on to source jewellery from all over the world, travelling to places like Bali, Indonesia to meet manufacturers in person and build real relationships with the people he worked with.

04

The creative spark

Jacob remembers watching that world closely: the creativity, the independence, the eye for detail, and the pride that came with building something of your own. It’s definitely where his own creative spark grew from. His dad even used to pay him 1p for every friendship bracelet he made, safe to say he got very good at it!

05

Carrying it forward

After Jacob losing his dad, Kaia Kini feels like our way of carrying that forward. A new generation, a new industry and a very different world of online commerce, but with the same belief in building something with care, character and real connection.

Behind the name

Why Kaia Kini

The name Kaia Kini has its own story too.

We knew exactly what we wanted to build, but we couldn’t quite find the right name. I had always wanted the brand to have a connection to my dad, Derek, who I sadly lost to cancer in 2025. The only problem was that “Derek” wasn’t exactly the easiest name to weave into a bikini brand!

For months, Jacob kept asking me if I’d come up with a name yet. And every time, my answer was the same: “Leave it with me.” Being the stubborn person I am, I was convinced the right name would come when it was meant to.

But as the business started taking shape, samples were being made, and everything was beginning to feel very real, Jacob finally cracked me. I had to admit defeat. We couldn’t keep kicking the can down the road, the brand needed a name, and it was time to let Jacobs ideas in.

Then, on a car ride to the gym, Kaia Kini popped into Jacob’s head.

Kaia was the dog we got to keep my dad company during the last few years of his life. He absolutely adored her, and I’m convinced she was one of the reasons he lived as long as he did. They were inseparable.

When my parents named her, they believed that “Kaia” meant “the sea” in Māori, a fitting choice, given that my dad’s sister and my brother both live in New Zealand. It later turned out that the meaning wasn’t quite what they thought, but by then it didn’t matter. The name had already become so much more than its literal definition.

So when Jacob came up with this name for the bikini brand, it felt like the perfect fit, a way to honour both my dad and a little dog who brought him so much joy.

With both of our dads woven into the story in different ways, Kaia Kini became something much more personal than a swimwear idea. It became a way of building something of our own, with meaning behind it, and creating a brand that felt like us.

Kaia Kini

Every Kaia Kini piece is created with the belief that great bikinis shouldn’t just look good, they should fit beautifully and make you feel amazing the moment you put them on, with separate sizing because life’s too short to squeeze yourself into a bikini that wasn’t made for you.

Whether you’re poolside, beach-bound, chasing sunsets or ordering your third spicy marg of the day, we want Kaia Kini to be the bikini you reach for when you want to feel your absolute best.

Thanks for being here.
