The composable digital mental model

Tame digital chaos before it compounds.

Archally is the composable digital mental model your teams and AI agents share — one source of truth for architecture decisions, API contracts, and agent context.

  • $12.9M/yr fragmentation cost per enterprise Gartner
  • 72% of executives say AI is built in silos Writer 2025
  • ~50% agentic-AI projects to be cancelled by 2027 Gartner
  • text-to-SQL accuracy with semantic model Snowflake

The 6 pillars

What makes Archally a composable digital mental model

Six pillars: composable, design-time, living, agent-readable, governed, enduring. One model emits all of them.

Composable

One model, many composable domains. Bounded contexts compose into a coherent whole — ID collisions detected at compose time today, conceptual conflicts on the roadmap.

Design-time

Validate, version, and time-travel your model before runtime locks decisions in. Move freely between as_is, to_be, and point_in_time.

Living and multi-view

One model emits Event Storming views, blueprint diagrams, brand strategy docs, PRDs, and OpenAPI / AsyncAPI / OpenRPC / GraphQL contracts — never goes stale.

Readable by agents

MCP servers expose model state as structured grounding for AI agents — not RAG over docs, inference-time context that lifts accuracy 20%+ and cuts tool calls by 39%.

Governed and evidenced

Decisions (ADR D### + BCC v5 BD###), motivation, value-streams, and GDSM methodology are first-class primitives. Every claim ties to evidence_refs.

Knowledge that endures

One blueprint emits living onboarding curricula, governed golden paths, and a permanent decision archive — so new engineers ramp in days, not months. Knowledge that endures, not documentation theatre.

Evidence

See It in Practice

Real systems, real scale, real outcomes.

Real Estate

Helped a platform team at a major real estate developer unify integration contracts across 10+ departments and establish traceable decision-making for regulatory compliance.

E-commerce

Modeled the full architecture of a large open-source e-commerce platform to enable blueprint migrations and change impact analysis across 2000+ entities.

Engagement Models

Three of the most common ways teams work with us. Bring one active change initiative; leave with a comparison plan.

1–2 Weeks

Architecture Diagnostic

Rapid architecture health assessment. Fixed scope, fixed price. We surface the architectural risks that matter most and produce a prioritised action list — not a 60-page report.

What You Receive

  • System health report with risk matrix
  • Interactive architecture map of the current state
  • Prioritised recommendations with effort estimates
  • Executive summary for leadership

Ideal For

Teams that need a defensible read on architecture risk before a major investment, hire, or transformation decision.

2–4 Weeks

Architecture Design Sprint

Intensive architecture design for new products or major modernisation. Outputs are machine-readable: a validated YAML blueprint that generates diagrams, API contracts, and decision records from a single source.

What You Receive

  • Machine-readable YAML blueprint of the system
  • Context maps + component and integration specs
  • Generated diagrams (C4, sequence, flow)
  • Architecture Decision Records linked to the model

Ideal For

Teams shaping a new product, planning a major refactor, or rebuilding an architecture documentation surface that has decayed.

Ongoing — 2–3 days/week

Fractional Architect Advisory

Sustained architecture presence without a full-time hire. Embedded with the team: PR reviews, design sessions, ADR maintenance, and live evolution of the architecture model as the system changes.

What You Receive

  • Weekly architecture reviews with the team
  • Decision records authored as decisions are made
  • Continuously updated blueprint of the system
  • Quarterly architecture health checkpoint

Ideal For

Teams that need an architect's discipline without the cost or commitment of a full-time hire.
