Our Story
Kidora began with a familiar part of family life: children grow quickly, but the clothes, toys, books and baby equipment they leave behind can still have plenty of life left in them.
Founded by Karolina Gudes in Chester, Kidora is a UK-only marketplace created to help parents and families buy and sell new and preloved baby and children’s items, find useful products locally or through nationwide delivery, and pass suitable items to another family rather than throwing them away.
Kidora was built from real family experience—not from a boardroom idea.
Where the Idea for Kidora Began
When Karolina’s daughter Sofia was born in 2022, the family home quickly filled with everything that comes with preparing for a baby: tiny clothes, blankets, accessories, toys, books and everyday essentials.
Some items were carefully chosen before the birth. Others were gifts from family and friends. Many were useful for only a short stage, and some were barely worn before Sofia had already outgrown them.
Before long, there were boxes of baby clothes, shoes, toys and equipment that were still in very good condition but no longer needed.
Like many parents across the UK, Karolina tried using large general marketplaces and social-media selling groups to clear space and pass those items on.
The experience was often more complicated than it needed to be:
- Long message conversations that did not lead to a purchase
- Buyers who arranged collection and did not arrive
- Listings surrounded by unrelated products
- Difficulty finding items specifically for babies and children
- Unclear payment and collection arrangements
- Repeated questions that could have been answered through a better listing structure
At the same time, family budgets were under growing pressure. Parents still needed clothes, toys, books, pushchairs, nursery items and school essentials, even though children often use them for only a short period.
That combination created the idea behind Kidora: a dedicated UK marketplace designed around the way families actually buy, sell, collect, deliver and reuse children’s items.
Built Together as a Family Project
Karolina shared the idea with her partner Martin and their close friend John.
Together, they began the long process of turning the idea into a working marketplace. That involved planning the buyer and seller journeys, designing the platform, building the native mobile apps, creating the website and developing the features needed for listings, messages, payments, delivery and local collection.
The team did not want to build another broad marketplace containing everything from furniture and cars to electronics and household goods.
Kidora would focus on one clear purpose:
Helping UK families buy, sell and pass on baby and children’s items.
A Marketplace Designed Around Family Life
Children’s items create different questions from many ordinary marketplace products.
Parents may need to check:
- Age, size and measurements
- Whether every original part is included
- The item’s genuine condition
- Compatibility with another product
- Whether an item is suitable for delivery or better collected locally
- Product instructions and recall information
- Whether the seller is a private individual or a business
Kidora was designed to make those details easier to organise and understand.
The marketplace includes categories for:
- Baby and children’s clothing
- Shoes and accessories
- Toys, games and books
- Pushchairs, baby carriers and travel equipment
- Nursery furniture, sleep and storage products
- Feeding, weaning, bathing and changing items
- School uniform and school supplies
- Pregnancy and maternity products
- Other useful baby and children’s items
Families can browse nearby listings through location-based discovery or purchase suitable products for nationwide delivery.

New, Preloved and FREE Items
Although Kidora was inspired by outgrown family belongings, the marketplace is not limited to second-hand products.
Sellers can list:
- New items that are genuinely unused and accurately described
- Preloved items with their true condition, wear and faults clearly shown
- FREE items priced at £0 for another local family to collect
The FREE option is an important part of Kidora’s purpose.
Some family items are still usable but may not be worth packaging and posting. A seller may simply want the item collected quickly, avoid unnecessary waste and help another family.
When an item is listed at £0:
- It appears to buyers as FREE
- It is available for local collection only
- The buyer secures it through Kidora checkout
- No card payment is required for the item
- No Buyer Protection fee is added
FREE does not mean that safety or honesty no longer matters. Recalled, broken, contaminated, incomplete or otherwise unsafe products must not be sold or given away.
Why Reuse Matters to Kidora
Babies and children move through clothes, toys, books and equipment quickly. An item may no longer suit one family while remaining useful to another.
Passing on suitable products can:
- Help a family spend less than buying everything new
- Give a seller more space at home
- Recover some of the money originally spent
- Extend the useful life of an item
- Reduce unnecessary disposal
- Help another child use something that might otherwise be stored or thrown away
Kidora does not claim that every used product should automatically be resold. Some products require detailed history, safety and hygiene checks, while recalled or unsafe products should never enter another reuse route.
The Kidora Parent Hub provides practical guides covering buying preloved, product safety, decluttering, local collection, donations, recycling and product-specific checks.
Making Family Essentials More Affordable
Children’s needs do not stop when household budgets become tighter.
Families still need clothes in the next size, shoes, books, toys, nursery products, school uniform and seasonal essentials. Buying suitable preloved products can make those costs more manageable, while selling outgrown items can return money to the family budget.
Kidora does not charge sellers a listing fee or seller commission on the item sale price. Sellers keep 100% of the price they set, subject to Kidora’s terms and any applicable payment-provider costs, refunds, reversals or chargebacks.
Buyers pay a mandatory Buyer Protection fee on paid purchases. The exact amount is displayed before checkout.
Supporting Local Collection and Nationwide Delivery
Kidora was built to support two different ways families often exchange children’s items.
Local Collection
Local collection can be practical for:
- Bulky nursery furniture
- Large toy bundles
- Pushchairs and other equipment
- Low-cost items that are not economical to post
- FREE listings
Paid local-collection purchases must still be completed through Kidora before handover. Collection details should be arranged privately through Kidora messages rather than published in the listing.
Nationwide Delivery
Delivery allows families to find suitable products from sellers elsewhere in the UK. Sellers choose an appropriate carrier and should package items carefully, retain postage evidence and provide tracking where practical.
Buyer Protection and Marketplace Support
Kidora adds a mandatory Buyer Protection fee to paid purchases.
Subject to the applicable policy and evidence, an eligible issue may include an item that was not shipped, was lost, arrived damaged or was significantly not as described.
Buyer Protection does not mean that Kidora has physically inspected, tested or certified a product. Buyers and sellers remain responsible for checking descriptions, condition, instructions, completeness, compatibility and product recalls.
Read the Kidora Buyer Protection Policy.
A Marketplace for Private and Pro Sellers
Kidora supports parents privately selling belongings their families no longer need, as well as Pro Sellers operating as businesses.
Pro Sellers are identified through their Pro status and have additional responsibilities. Different return, cancellation, refund and consumer-rights rules may apply when buying from a business.
This distinction helps buyers understand who they are purchasing from before completing checkout.
More Than a Place to Buy and Sell
Kidora is growing beyond the marketplace itself.
The Kidora Parent Hub has been created to give parents useful UK-focused information across subjects including:
- Things to do with children
- Local family guides
- Saving money
- Buying and selling children’s items
- Pregnancy and baby preparation
- Toddlers, preschool and primary school
- Family support and parenting resources
The guides are intended to help parents find official information, ask better questions and make practical decisions. Health, legal, financial, education and product-safety pages signpost appropriate NHS, GOV.UK, council and recognised specialist sources rather than replacing professional advice.
Built in Chester, Growing Across the UK
Kidora was founded in Chester, close to the communities of Wrexham, Flintshire and North Wales where the marketplace first began developing local activity.
Its purpose, however, has always been UK-wide.
Kidora supports parents and families throughout the United Kingdom through:
- Native iOS and Android apps
- A web marketplace
- Nationwide delivery
- Local collection
- English and Polish language support
- Family-focused categories and discovery
- Practical Parent Hub resources
Kidora’s approach is to build genuine activity in communities, learn from parents and grow location by location rather than pretending every area is already equally active.
Meet Karolina, Founder of Kidora
Karolina Gudes is the founder and public face of Kidora.
She is a mum of two who understands how quickly family life becomes filled with clothing, toys, equipment, appointments, work and everyday responsibilities.
Kidora was created because she wanted a marketplace that felt more relevant to parents: a place where baby and children’s items were not an afterthought, where local collection and delivery could both work, and where a suitable item could be sold, bought or offered FREE instead of forgotten in a box.
Her founding belief remains at the centre of Kidora:
“Every item carries a story. Every sale helps another family.”
