This page is the high-level current-state portrait of the DomiDo business: what the project is doing, at what scale, with what infrastructure, and with what kind of cost discipline. DomiDo is built by Avvyland Limited (United Kingdom) and sells universal blocks and fasteners only; every construction shown on the platform is a user-generated design. This synthesis is the picture a newcomer needs to understand the business shape — it covers product positioning, the business case, the economic model, a feasibility assessment, the architecture and infrastructure footprint, funding posture, decision checkpoints, the leading opportunities and risks, and the conditions the operating plan rests on. It is current-state only, not a forecast or a forward-looking projection.
DomiDo is an AI-assisted design-to-physical pipeline. A user describes an outdoor structure as a text prompt, a reference image, or an uploaded 3D model. The platform generates a buildable design, runs it through the dd-mesher pipeline, produces a validated bill of materials and an optimised block layout with a structural-integrity assessment and a step-by-step assembly sequence, and ships a kit of universal blocks and fasteners to the buyer's door. The pipeline is deterministic: the same input produces the same kit. The physical product is a set of universal blocks and fasteners — a small number of stock-keeping units of an interlocking polymer block with a patent-pending self-complementary tetrahedral relief connection mechanism, plus the fasteners required to combine them. The block material is preliminary: the product conformity notice currently shows ABS as a placeholder, and polypropylene, phenol-formaldehyde, and other resins remain open candidates without changing geometry. The connection mechanism uses a square base plane partitioned into four quadrants, each containing one tetrahedral protrusion and one complementary recess, arranged in a four-fold rotational array — so any block connects to any other block in any orientation, with no male or female face distinction and no fixed top or bottom. DomiDo blocks are positioned as an adult outdoor creative-building system for decorative and utility structures; they are explicitly not toys and not marketed toward children. The platform is part of the Avvyland family of products, alongside Avvyland's interactive virtual-world product.
The business creates value across four overlapping streams. Direct-to-consumer kit sales sell kits of universal blocks and fasteners to consumers, with the kit content determined by each user's bill of materials. AI design credits are a subscription product giving users access to the AI generation features at a tier-appropriate monthly allocation. A designer marketplace opens in Phase C: designers create and publish designs, and the platform takes a share of each kit sale that originates from a designer's design. Uniqueness fees also open in Phase C, applying a small fee on designs that are unique to one buyer rather than discoverable in the public gallery. The competitive moat is the four-pillar intersection: AI-assisted design, proprietary three-dimensional-to-block conversion (the dd-mesher pipeline), functional outdoor-scale physical structures, and a designer marketplace. No competitor currently occupies the same intersection.
The economic model rests on a small number of cost levers and a clear unit-economic structure. The dominant operating cost is the team. It is composed of a small salaried core plus a larger equity-only contributor group, with the equity-only contributors carrying no salary cost during the validation phase. Infrastructure cost is small and stable, well under one percent of revenue across the multi-year projection. Marketing carries a meaningful share of the first-year cost as the platform needs visitor acquisition before any revenue ramp. Patent filing, freedom-to-operate analysis, and product-safety testing are budgeted explicit line items.
Kit cost-of-goods is driven by amortised tooling, material, machine and labour, kitting, packaging, and outbound shipping. At launch volumes, amortised tooling dominates the per-block cost; as volumes climb past the multi-cavity tooling thresholds, the per-block cost falls sharply. The kit margin target is a clean percentage of the retail price set so that gross margin holds across the kit-size range. AI generation cost is variable, sometimes unpredictable, and managed by per-request, per-user, and per-system budgets — the AI cost per pipeline run declines materially over time as model providers compete and as the platform consolidates traffic with the best-fit providers. Payment processing fees follow Stripe's standard rates plus value-added services such as Stripe Tax; payment cost as a share of revenue is small and stable.
AI design credit subscriptions sit across a small number of tiers, each with a monthly credit allocation suited to a different user intensity. The credit token system tracks per-user balances and per-generation deductions, and free-to-paid conversion uses transparent overage cues. Subscription lifecycle (trial, renewal, dunning, cancellation, plan change) is webhook-driven. Across all of these streams, the break-even logic is staged: the first phase generates only subscription revenue, the second phase adds kit revenue once tooling is complete and the bill-of-materials path is validated, and the third phase opens marketplace and uniqueness-fee revenue. Cash discipline is maintained through decision checkpoints rather than aggressive cost cuts.
The formal five-dimension assessment summarises the project's current state. The composite assessment is to proceed with conditions actively managed; the paragraph below the table walks through each dimension.
| Dimension | Assessment | Summary |
|---|---|---|
| Technical | Strong | The dd-mesher pipeline is functional; the AI generation stack is multi-provider with no single-vendor lock-in; infrastructure cost is small and stable; there are no critical technical blockers. |
| Operational | Moderate | The team is small, with knowledge concentration in the backend and chief-technology-officer roles. Documentation, cross-training, and a planned headcount increase are active mitigations. |
| Legal and regulatory | Moderate to strong | The DomiDo trademark is registered with the UK Intellectual Property Office; a patent application for the interlocking mechanism is to be filed within the first month after the launch programme starts; freedom-to-operate analysis is budgeted and scheduled; UK Conformity Assessed (UKCA) testing is budgeted before the kit-sales phase begins; no regulatory blockers have been identified, but the regulatory checks are pre-launch prerequisites that have not yet been completed. |
| Market | Moderate to strong | The addressable market is large; the four-pillar intersection is favourable; pre-order validation gates manufacturing investment before significant capital is committed; demand is unvalidated until kit sales begin. |
| Financial | Moderate | The first year is an investment year. Capital is committed by the founders across staged tranches with explicit drawdown triggers; the funding horizon covers a multi-year period to a planned external-equity round; founders retain a majority position entering that round. |
The architecture is a modular monolith backend in Go, a Progressive Web Application frontend in React Native with Expo and React Three Fiber, an event-driven asynchronous worker for compute-intensive pipelines, and a small managed-service surface (Stripe for payments, MongoDB Atlas for the primary data store, Redis with Asynq for the queue, and a single product-analytics provider with European-Union data residency). The infrastructure runs on a European-Union cloud provider with a self-managed Kubernetes distribution. Infrastructure cost is small in absolute terms and very small relative to team cost; it is not a material lever on the business outcome. Cost discipline focuses on the few items that actually shape runway: team headcount, tooling investment, and marketing spend. The technology stack is described in the architecture options page; the architecture choices are described in architecture choices.
The project is funded by the founders across staged tranches. The funding strategy keeps external dilution at zero until the planned external-equity round. The tranches are milestone-triggered rather than calendar-triggered: a launch tranche, a growth tranche after the first peak demand period is validated, and a contingency tranche drawn only if cash falls below a defined working buffer. The contingency tranche is rarely expected to be drawn; the existence of the tranche is a guard against schedule slippage in the planned external-equity round. A separate non-dilutive cash source is the United Kingdom research-and-development tax credit, which provides a material cash injection in the year following each qualifying expenditure and reduces the effective cost of the validation period.
The plan includes structured decision checkpoints. Each checkpoint asks a small set of go-or-no-go questions and triggers a clear action. The checkpoints span the validation year and continue into the kit-sales phase and beyond. The most consequential checkpoint is the manufacturing go-or-no-go decision before significant tooling capital is committed; that checkpoint requires both a demand-signal threshold and a cash threshold.
Three opportunities sit at the front of the operating plan. The research-and-development tax credit provides a material non-dilutive cash injection. Marketplace and uniqueness-fee revenue adds gross-margin-favourable streams as the designer side of the platform reaches critical mass. And the universal-block model removes per-product tooling cost — one set of moulds serves an unlimited design catalogue, allowing rapid catalogue expansion with zero incremental manufacturing cost per new design.
Three risks anchor the active risk-management work. The first is that kit demand fails to materialise at the modelled conversion rate, in which case revenue grows more slowly than the plan and the operating period needs to be extended. The second is that the backend and chief-technology-officer concentration of knowledge creates a single point of failure; documentation, cross-training, and a planned headcount increase are the active mitigations. The third is cash management before the multi-year revenue ramp; staged founder tranches and the contingency tranche bridge to the planned external-equity round, and a written wind-down plan is feasible and humane if the business needs to stand down. The detailed risk catalogue is in risk analysis.
The active operating plan is conditional on a small number of operating disciplines being maintained. Checkpoint discipline means go-or-no-go gates are honoured with the actions they require. Tooling strategy is flexible: tooling is funded from operating cash where favourable, or deferred and funded from operating cash and tax credits where conditions tighten, with the option to pull tooling forward if pre-order demand is strong. Pre-order validation requires interest reservations and pre-orders to accumulate enough demand evidence before tooling capital is committed. Backend bus-factor mitigation requires cross-training and documentation to move the backend bus factor above one before the manufacturing phase begins. Equity team retention requires structured vesting agreements in place before launch and weekly hours explicitly agreed. Patent filing requires the United Kingdom patent application for the interlocking mechanism to be filed within the planned window. Product-safety testing requires UKCA compliance testing completed before the kit-sales phase opens. A cash-buffer policy keeps the business above the working buffer. And the freedom-to-operate analysis is completed before significant capital is deployed.
DomiDo is a phase-gated platform that turns AI-assisted designs into kits of universal blocks and fasteners, operated by a small team on a small infrastructure footprint, funded by the founders across staged tranches to a planned external-equity round, with the technical foundation in place and the validation work in motion.
