White Paper

YuMaMi is a community-driven marketplace built for parents. We make it simple, safe and rewarding to buy and sell new and pre-owned children's items — from clothing and toys to strollers and car seats — directly between families.

• What YuMaMi is

  A modern marketplace dedicated exclusively to parents and children's products, focused on quality, trust and ease of use.

• Marketplace for parents

  A platform designed around the real needs of mothers, fathers and caregivers, with categories, filters and conversations that fit family life.

• Buy and sell new and pre-owned items

  From brand-new boutique pieces to gently used essentials, YuMaMi gives every product a second chance at being loved.

Our mission is to make parenting more affordable and more sustainable by giving children's products a longer life and a wider home.

• Extend the lifecycle of children's products

  Children outgrow items in months, not years. YuMaMi keeps strollers, clothes and toys in circulation between families instead of in storage or landfill.

• Reduce waste

  Every reused item is one less product manufactured, shipped and discarded — meaningfully reducing the environmental footprint of raising a child.

• Help families save money

  Quality children's goods at a fraction of retail prices, plus the ability for families to recover value from items they no longer need.

YuMaMi is designed to feel natural from the very first tap. The full journey — from joining to closing a sale — takes minutes.

• Create account

  Sign up in seconds with email or Google. Your profile becomes your reputation across the marketplace.

• Publish listing

  Add photos, a title, condition and price. Listings go live immediately and are instantly searchable.

• Search and buy

  Browse by category, city or keyword. Save favourites, add to cart and reach out to sellers when something feels right.

• Secure communication

  Buyers and sellers chat inside YuMaMi — no need to share phone numbers or external accounts to agree on details.

• User ratings

  After each successful exchange, both sides leave a rating. Reputation builds over time and helps the community self-regulate.

Parents trust YuMaMi with items for their children. We treat that responsibility as the foundation of the product.

• User verification

  Verified email and phone, with optional identity checks for high-value sellers, ensure the people you talk to are real.

• Reporting system

  Every listing, profile and message can be reported in one tap. Our moderation team reviews reports within hours.

• Content moderation

  A combination of automated checks and human review keeps prohibited items, unsafe products and inappropriate content off the platform.

• Scam prevention

  Pattern detection, payment guidance and clear in-app warnings protect users from common marketplace fraud techniques.

Your data belongs to you. YuMaMi collects only what is needed to operate the marketplace and protects it with industry-standard safeguards.

• GDPR compliance

  We operate under the European General Data Protection Regulation, giving every user the right to access, export and delete their data.

• Data protection

  All personal information is encrypted in transit and at rest, with strict access controls inside the company.

• Secure authentication

  Authentication is powered by hardened identity infrastructure, with password reset flows, session management and optional social sign-in.

We are building a payment experience that protects both sides of every transaction without getting in the way.

• Secure transactions

  All future card payments will be processed by PCI-DSS compliant providers — YuMaMi never stores raw card data.

• Buyer and seller protection

  Clear policies define what is covered, how disputes are handled and how funds move between parties.

• Future escrow support

  An optional escrow flow will hold funds until the buyer confirms delivery, raising trust for higher-value items like strollers and car seats.

Sustainability is not a side feature of YuMaMi — it is the entire reason the platform exists.

• Circular economy

  By default, every transaction on YuMaMi keeps a product in use rather than producing a new one.

• Reuse before disposal

  We encourage families to resell or donate before discarding, with categories and flows designed around second-hand items.

• Lower environmental impact

  Local-first listings reduce shipping distances, and reuse cuts the raw materials, water and energy needed for new production.

YuMaMi is being built in clear phases, each one unlocking deeper value for the community.

YuMaMi aims to become the leading marketplace for children's products in Bulgaria and Eastern Europe — a trusted, sustainable and joyful place where every family can give and receive value across generations of childhood.
