Tribu Box—Kids' Toys Subscription Model—Powered by circuly

‍Tribu Box was born in a Berlin prenatal class.

Co-founders Cilia Laug and Daniela Illanes, both first-time mothers, both new to Germany, realised they were thinking about parenthood differently from everyone else in the room.

While others talked about the wonder of newborns, Cilia and Daniela were asking harder questions: why is the right toy so difficult to find, so expensive to buy, and so short-lived in a child's life?

Children outgrow toys fast. A rattle that captivates a three-month-old holds no interest by six months.

A stacking toy perfect at nine months gets abandoned well before a child's first birthday. And yet parents keep buying, accumulating plastic, spending money, filling landfills, when what they actually need is the right toy for right now.

"Tribu is all we wanted as first-time parents and we could never find. So, we built it." — Cilia Laug & Daniela Illanes, Co-founders

The two founders launched Tribu Berlin GmbH in early 2021, with a clear mission: give families access to developmentally curated, expert-selected toy boxes on a rental subscription and take those toys back when children were ready for the next stage.

Today, Tribu Box serves over 10,000 families across the DACH region and is backed by Ravensburger Next Ventures.

How the Tribu Box Model Works

Tribu Box offers a rolling toy rental subscription for children aged 0 to 3+ years, starting from €19.99 per month.

Each box is curated to match a specific developmental window, there are 12 age-matched boxes covering the first three years of a child's life, with names like Hedgehog (0M+), Mouse (3M+), Fox (6M+), and Bear (9M+), plus a further range for children aged three and above.

Every box is selected by child development experts and paediatricians, not by an algorithm.

The mechanics of the subscription are built around how families actually live:

• Swap every 90 days: The standard rental period is 90 days. Once a family is ready to move on, they initiate a swap through the customer portal, return the current box, and receive the next developmental stage.
• Early swaps for a small fee: If a child moves through a stage faster than expected, families can swap before the 90-day window closes by paying a small early-swap fee.
• Keep a toy you love: If a child bonds with a particular toy, families can purchase it directly — keeping what matters, returning the rest.
• Insurance included: All toys are insured against normal wear and damage, removing a key source of anxiety for parents of young children.
• Flexible plans: Monthly, semi-annual, and annual subscriptions are available.
• Simple returns: Toys are sent back via a pre-included return label, then cleaned, checked, and passed on to the next family — completing the circular loop.

Toys that retire from the rental cycle go to the Tribu Shop, sold at reduced prices to families who prefer ownership. Nothing goes to waste.

The Problem: Shopify and Recharge Were Built for the Wrong Model

When Tribu Box first launched, the team built their subscription infrastructure on Shopify with Recharge Payments, a standard combination for e-commerce subscriptions.

The problem became clear quickly: Recharge treated every billing renewal as a new order, which meant it charged shipping again every month — even when no new box had been sent.

For consumable subscriptions, coffee, vitamins, razor blades, that logic is correct. A renewal means a new shipment.

But Tribu Box doesn't work that way. Families hold a box for 90 days. Billing is tied to access, not dispatch. Recharge couldn't model that distinction.

And the billing issue was only the beginning.

Tribu's model raised operational questions that generic tools had no answers for:

• Should the subscription renew if the box hasn't come back yet?
• How should an early swap fee be calculated and charged automatically?
• What happens when toys come back with items missing?
• How does stock get updated in real time when a return arrives?

Tribu needed a subscription management system built specifically for physical product rentals — not repurposed from SaaS or consumables.

The Solution: circuly

Tribu Box moved to circuly in 2023. The core requirement was straightforward: a system flexible enough to match a model that no off-the-shelf billing tool could represent.

As co-founder Cilia Laug put it:

"circuly powers all the standard subscription operations we need (payments, invoicing, communication, and customer portal), but what we value most is its flexibility to adapt to our unique business model." Cilia Laug, co-founder at Tribu Box

Since making the switch, Tribu Box has averaged around 90% year-over-year growth in active subscriptions.

The Core Logic: Return-Gated Renewal

The most important mechanic circuly enables for Tribu is return-gated renewal: the subscription stays active, but a new cycle only begins once the current box has been returned — or the customer has signalled intent to return it.

Without this, Tribu faced an impossible choice: charge customers for a new period before the box is back (unfair), or pause and manually restart billing each time (unscalable). Neither works at volume.

With circuly, the subscription rolls over automatically when no return or return intent has been registered. The billing clock stays in sync with the physical product cycle — exactly as a rental model requires. No manual intervention. No incorrect charges.

Automating the Edge Cases

Beyond the core renewal logic, circuly handles the operational edge cases that define Tribu's day-to-day:

• Early swap fees: When a family requests a swap before 90 days, circuly automatically charges the correct fee — no manual calculation or support ticket required.
• Missing item charges: If toys come back incomplete, circuly automatically charges for missing items — protecting inventory economics without staff having to chase customers.
• Subscription and price adjustments on extension: When customers extend their rental period, circuly adjusts the subscription and pricing in the background automatically.
• Asset tracking and stock management: Every return updates inventory in real time — no manual reconciliation.
• Customer self-service portal: Families manage their own swaps, extensions, and account details through circuly's hosted portal — keeping the support load low as the subscriber base grows.
• Transactional communication: Swap confirmations, return reminders, billing notifications — all triggered automatically by circuly at the right moment.

"circuly makes it possible for us to run Tribu Box the way we imagined it." — Cilia Laug, Co-founder

Operations Where circuly Supports Tribu Box

circuly is the subscription management system behind Tribu Box, automating the core infrastructure needed to run a rental subscription for physical products. Out of the box, circuly handles subscription management, recurring billing and invoicing, asset tracking, product lifecycle management, return management, a customer self-service portal, transactional communication, and fraud prevention through credit checks — allowing the Tribu team to focus on growth and curation rather than manual operations.

Conclusion

Tribu Box demonstrates that a genuinely circular product model demands infrastructure built for it — not adapted from it. The 90-day swap cycle, return-gated renewal logic, early-swap fees, missing item charges, and real-time stock updates: none of these could be handled reliably by generic billing tools. With circuly running the operational layer since 2023, Tribu Box has grown active subscriptions by an average of ~90% year-over-year, crossed the 1,000-subscription milestone, and served over 10,000 families — all while keeping operations lean enough to scale without proportionally growing the team behind it.
