Built for GPROJECTS · May 2026

Redefining Construction & Real Estate. BUILD IT.

The platform that turns West Africa's $80B+ construction market from an Excel-and-WhatsApp economy into something contractors can run a business on. Marketplace. Escrow. Project management. Verified artisans. AI architect. One platform, eight weeks, one production launch — and a Year 1 revenue target of $2M from the day it ships.

GPROJECTS pitched it. Black & Yellow builds it.

The Opportunity

You've drawn the
blueprint.
Time to build it.

Nigerian urbanisation is the largest formal housing-deficit market in West Africa — 28 million units short, +80% cement inflation, and a construction sector still running on WhatsApp threads and paper receipts. The deck identifies $80B+ of potential and a Year 1 revenue target of $2M. The lane GPROJECTS has pitched is real. It's open today. It won't be in eighteen months.

Procore charges $375/month and ignores Africa. Houzz lives in American renovations. Alibaba ships materials with no opinion on construction. None of them have built what GPROJECTS has already imagined — and none of them are paying attention to Lagos. This engagement turns the pitch into the platform. Eight modules. Eight weeks. One production launch. The platform stops being a pitch and starts being a business.

GPROJECTS pitched the future. Now we build it.

The
landscape
is unbuilt.

Procore runs project management for the West. Houzz Pro lists artisans for American renovations. Alibaba ships materials globally with no opinion on construction. Each is a giant in its lane — none of them stitch the three together for African construction. That's the unoccupied lane GPROJECTS owns today. This build claims it before anyone else does.

Procore End-to-end PM & CRM for the West. No marketplace, no escrow, no artisan network. $375/month minimum — pricing built for US general contractors, not Lagos developers. Active · West
Houzz Pro Artisan directory plus invoicing — built for US and UK home renovation. No materials trading, no real project management, no presence in African markets. Renovation Only
Alibaba Global B2B materials trading at industrial scale. No verified artisans, no project management, no escrow tuned for construction. Generic friction for African buyers. Huge · Generic
BUILD IT Marketplace, escrow, project management, verified artisans and REIT-ready — all under one roof. Nigerian-first compliance. Co-op pricing that beats every wholesaler in Lagos. You

Three giants. Three silos.
One platform stitches them. It's either you, or someone else, inside 12 months.

This will ship.
Here's why.

01
Engineering-grade architecture from day one
Postgres, Redis, queue workers, audit logs, NDPR posture. Not a v0 demo dressed up — the spine that survives 10× growth without a rewrite. The platform is built today for the user count you'll have in Year 3.
02
Nigerian-first compliance & payments
KYC tuned for BVN, NIN and CAC verification. Paystack escrow with a proper held-funds ledger. Customs and duty logic that knows local rules — not US tax assumptions wedged into Lagos. The platform passes a regulator review on day one.
03
Founder-level ownership, no agency layers
Architecture, code, security, deploy and post-launch support all sit with the same pair of hands. No junior delegation, no account-manager middlemen. You always know who's answering the phone at 2am — and that person can actually fix it.
04
Eight weeks of intensity, not three months of estimates
Weekly Friday demos on a single staging URL. You see real progress every seven days — not a deck, not a wireframe, the actual platform. If something's wrong, you catch it in week two, not month four.
