The name behind the product
φ is nature's own design algorithm

φ = 1.6180339… — the Golden Ratio. The Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55… converges toward φ with every step — nature's own law for efficient and beautiful growth, visible everywhere from sunflowers to the greatest architecture ever built.

🌻
Sunflower Seeds
34 clockwise, 55 counterclockwise spirals — consecutive Fibonacci numbers. Nature's optimal packing pattern.
🐚
Nautilus Shell
The logarithmic spiral follows φ precisely at every quarter-turn — grown over millions of years without any design tool.
🏛️
The Parthenon
The entire façade fits a golden rectangle. The greatest architects always found φ — knowingly or not.
🧠
PhiMind + Geometry
The AI that applies φ precision to every building — from a spoken brief to a permit-ready drawing, in minutes.
"We did not name the company after a Greek letter. We named it after the universe's own design language — the same constant that appears in the greatest architecture ever built, now powering the AI that designs the next generation of it."

The problem
The AEC industry runs on a broken paradigm
💸
$55K+
per year, per 10-person firm
Autodesk AEC Collection charges $3,375–$3,675 per seat per year. Software licences before a single line is drawn.
⏳
60%
billable hours lost to drafting
Architects spend more than half their time manually drawing walls and calculating spatial geometry — not designing.
🔄
2–6 wks
per client change request
Every time a client says "move the kitchen" — it means weeks of manual redrawing before they see anything new.
🗂️
5–8
tools for one project
Revit, SketchUp, Navisworks, ACC, Bluebeam, Excel, WhatsApp — none talk to each other cleanly. Data silos cost time and money.
📋
Manual
compliance every project
Building regulations checked from memory and experience — not a system. One missed rule means weeks of costly redesign.
🎯
All-in-One
is missing from the market
No platform combines AI design generation, automatic compliance, browser-native access, and multi-discipline coverage. Until now.

Technology edge
Building our own AI — the PhiMind Geometry Model (PGM)
Spatial Accuracy Benchmark
Higharc GBM — proven domain model (US residential only)
98.2%
PGM — our target (global boutique AEC, all disciplines)
95%+ target
Claude 3.5 Sonnet (general LLM — Phase 1–2)
76.4%
Validation: Higharc proved domain AI outperforms general LLMs on spatial tasks and raised $83M — for US residential only. PGM applies the same principle to the entire global boutique AEC market.
Benchmark: Higharc DDEP published benchmark, 2026
Phase 1–2 (Now)
Claude + OCCT Geometry Kernel
LLM writes parametric Python scripts → OCCT executes exact B-Rep geometry. Deterministic — no hallucinated walls. Production output identical to Autodesk Revit quality.
Phase 3 (Month 18–30)
PGM — Own Domain Transformer
Trained on 5,000+ real boutique AEC projects. BIM-native tokenization (buildings as language). 100% owned IP. Self-improving with every project. Licensable to other AEC software vendors.
PGM cost reduction at scale
Self-hosted PGM drops cost per generation from $0.10–0.50 → $0.01–0.05. At 100,000 monthly generations: $9,000–45,000/month saved vs external LLM API.
φ
Competitive advantage
Four moats that compound over time
1
Compliance Knowledge Base
Building codes are jurisdiction-specific, legally complex, and require months per region to ingest correctly. By Year 3: 12+ jurisdictions, 200,000+ pages of validated regulatory knowledge. A new entrant starting today begins 3–4 years behind.
2
LLM-to-Geometry Bridge
Connecting a general LLM to an OCCT geometry kernel with validation, error recovery, and compliance integration is novel engineering that does not exist in production anywhere today. Once built and proven on thousands of real projects, it is extremely difficult to replicate.
3
PhiMind Geometry Model (PGM)
Domain-specific Transformer trained on 5,000+ real AEC projects. 100% owned IP. Improves automatically with every project. Cannot be replicated without our training data — which compounds with every customer every month.
4
AEC CX Layer — Permanently Gated
Drawing-aware client helpdesk answers from the actual project file. Only works because we own the design data. Intercom, Zendesk, Salesforce — permanently locked out. This moat cannot be crossed by any company that does not own the BIM design layer.

Universities as long-term market infrastructure
Individual Student Access
Register with an academic email. Student tier at significantly reduced or zero cost. Exports carry an education watermark. No commercial use permitted. Platform prompts upgrade when they enter professional practice.
University Institutional Licence
University pays one annual licence. All enrolled students get free, unrestricted Student tier access. Lecturers get Pro tier. Institution management dashboard. No watermark for institutional students — a university recruitment advantage.
"When a student graduates and joins an architecture firm, they already know the platform. When that firm considers software, they are influenced by the team member who used it since university. Over years, they become the advocates who drive adoption across entire practices."

How We Reach $1M ARR at Month 12
100 UK paying firms × avg $520/mo$52,000
45 Netherlands firms × avg $450/mo$20,250

Professional services (implementation)$6,000
Monthly Recurring Revenue — Month 12$91,250
Annualised Run Rate (ARR)$1.095M
Can we exceed $1M ARR? Yes — strong PLG via client sharing links, RIBA CPD leads, early US pipeline (letters of intent Month 10–11), and enterprise trials push the stretch case to $1.2M–$1.5M ARR at Month 12.

"I didn't read about this problem in a report. I lived inside it for nine years — drawing walls at midnight, checking building regulations page by page, watching clients struggle to visualise what I was trying to show them, and spending weeks redrawing the same floor plan after every change request. It sparked me to build PhiMindLabs Geometry — because I know exactly what is broken, and I know what good looks like."

The vision
The φ of AEC & BIM software — globally
Product Vision
"The most useful, intelligent, and accessible design platform in the AEC and BIM industry — for both boutique practices and global enterprises. I want every person who touches a building project to feel how technology and AI can make things simple and useful — which always felt complicated before."

— J. Nazre Aalam Rafeez, Founder & CEO
10-year platform thesis
By 2036, PhiMindLabs Geometry is the default AI-native design platform for both boutique AEC firms and enterprise architectural practices globally. PGM is licensed to AEC software vendors as an intelligence API. The AEC CX layer has defined a new product category. Boutique practices use it for speed and creativity. Enterprise firms use it for scale, compliance, and intelligent collaboration across large multidisciplinary teams.
Organisational Vision
At PhiMindLabs, we are building something rare: a deep-technology company that grows with integrity. We believe our team, our partners, and our customers must all thrive together — not one at the expense of another.

We lead with lean and honest leadership, where every person is heard and every voice matters. We value long-term excellence over short-term gain, and we measure our success not only in the depth of our platform, but in the dignity of the people who build it and the trust of the professionals who use it every day.

Technology and human dignity are not in tension. At PhiMindLabs, they compound each other.
5–7 year acquisition landscape
Autodesk: $50B mkt cap Trimble: $15B mkt cap Bentley: €8B mkt cap Procore: $8B mkt cap
A Series B-stage PhiMindLabs Geometry with $5–10M ARR, 200+ customers, PGM deployed, and a unique AEC CX layer is a compelling acquisition target in the $100–500M range.
