Bizscree — Platform for startups and aggregators

Overview

Bizscree replaces the fragmented reporting where startups have to duplicate their data for every investor, incubator, or accelerator they work with. Instead, companies create a single comprehensive profile — financials, team, projects, KPIs — and grant each aggregator exactly the level of access they need.

"Build once, share many" — a single source of truth per company, with granular control over who sees what.

What the system does

• Company profiles — Financials, team, projects, business plan, and data rooms all in one place
• Portfolio management — Aggregators get granular permission controls over their portfolio companies
• Virtual companies — Aggregators can create profiles for companies not yet on the platform; real companies can later claim and take them over
• KPI tracking — Custom metrics, targets, and trend analysis per portfolio company
• Portfolio analytics — Sector breakdown, stage distribution, and performance reports
• CEO reports — Structured updates and progress boards
• Passwordless auth — Magic-link sign-in with multi-organization support
• Real-time notifications — WebSocket delivery via SignalR
• AI-powered features — CEO briefs and suggestions via OpenAI
• PDF export — Reports and profiles as downloadable PDFs
• Audit logs — Full traceability for compliance
• Guided onboarding wizards — For both company and aggregator organizations

Technical choices

Bizscree is built as a clean SPA + API architecture with full separation between frontend and backend:

• End-to-end type safety — Auto-generated TypeScript client from the OpenAPI spec via hey-api
• Organization-aware authorization — Middleware extracts organization context; policies and handlers scope access per aggregator
• Real-time updates — SignalR hubs push notifications straight into the UI
• Rate limiting — Fixed-window policies protect sensitive endpoints (auth, AI, uploads)
• Health checks — /health endpoint for load balancers and monitoring
• Structured logging — Serilog with rolling files in production
• Production-hardened — Ten implementation phases delivered: security, infrastructure, deployment, features, polish, notifications, analytics and KPIs
