The Mega App Spec

Before you build, know what's worth building.

This is the demand map for the entire Mycelium. Three registers cover every job a venture could need — from auth to tokenomics, from legal tech to construction payments, from hot wallets to multisig. Features that score high enough earn a PRD and become shared capabilities. Everything else gets partnered or skipped.

The Three Registers​

RegisterWhat It CoversFeaturesKey Question
Horizontal SaaS177 features across 24 categories — auth, billing, data, AI, voice, blockchain, IoT, geospatial, booking, field ops, UI177Where do we have unfair advantage?
Vertical SaaSIndustry opportunities scored by lucrativity, effort, and market size — PropTech expanded to 6 sub-verticals6 verticalsWhich vertical do we enter first?
On-ChainWallet safety, DePIN device registration, property tokenization, carbon credits, attestationAll chainsHow do we make the next action safe and obvious?

Scoring Methodology​

Every horizontal feature is scored on four dimensions (1-10 each):

DimensionWhat It Measures
CurrentHow much capability exists today
FitHow well it fits the platform architecture
ValueHow much customers care
EdgeHow differentiated we are vs alternatives

Priority = (Current + Fit + Value + Edge) / 4 x Edge

Edge is the multiplier. High-value commodities (payments, auth) score high on Value but low on Edge — partner for these. High-edge capabilities (multi-agent orchestration, smart contracts) compound — own these.

Top 10 by ROI​

The highest-scoring features across the entire superset, ordered by priority score:

9 of the top 10 already have a Mycelium PRD. The one that doesn't — CI/CD Automation — is developer tooling that compounds through the engineering repo, not here.

Critical Gaps​

Features that score high on Value but have no Mycelium PRD yet:

The Loop​

SUPERSETS (score demand)
  → MYCELIUM PRDs (spec highest-ROI capabilities)
    → MUSHROOM CAPS (prove in one venture)
      → COMMISSION (verify against spec)
        → SCALE (promote to platform primitive)

The supersets are the input. The Mycelium PRDs are the output. The mushroom caps are the proving ground. Nothing scales until it's commissioned.
