AI coding tools have dramatically lowered the barrier to building enterprise software prototypes. But a prototype is not a product, and a product is not a platform your team will rely on every day to make investment decisions worth billions of dollars. Firms should build where it creates genuine investment edge, and buy commodity infrastructure from specialists.
Who This Is For
- Chief Investment Officers (CIOs)
- Directors of Research
- Heads of Investment Technology
- Chief Technology Officers (CTOs)
The Prototype Trap
The initial build is intoxicating. Stand up a database, wire in an AI API, generate structured notes in a slick front end and within a week you have a demo that impresses the CIO.
The Problem: The build that took two weeks to prototype takes 6–12 months to make production-grade. Then it needs a team to maintain it indefinitely.
Hidden Complexity
Real-world requirements compound quickly:
- MS Office Integration: Add-ins, Excel check-out/in, version history, calculation scripts, consensus vs. internal diffs.
- Permissioned AI: Role-based access, BYO API keys, grounded citations, zero data training commitments.
- Regulatory Compliance: Audit logs for s1043A Corps Act (AU), FCA SYSC 6.1 (UK), SEC Rules 17a-3/17a-4 (US).
- ESG Workflows: Scorecards, engagement logs, proxy voting, SFDR/TCFD reporting.
- Long-Term Maintenance: Security patches, schema evolution, regulatory changes, key-person risk.

Buy: Research management infrastructure, coordination layers, compliance frameworks.
Build: Custom AI models, proprietary data integrations, unique analytical frameworks, bespoke screening tools. These are features no platform provider will build for a user base of one.
