01. Core Bottleneck

B2B marketing teams juggle multiple separate tools to build a landing page, write emails, configure webinars, and score leads. HiveGPT enabled marketers to type one high-level prompt and generate an entire publish-ready campaign. However, sending every sub-task to frontier models made the platform slow, expensive, and inconsistent in brand voice, with high risk of cross-tenant data leakage in multi-tenant environments.

Problem Definition //

The Business & Architectural Challenge

B2B marketing teams juggle multiple separate tools to build a landing page, write emails, configure webinars, and score leads. HiveGPT enabled marketers to type one high-level prompt and generate an entire publish-ready campaign. However, sending every sub-task to frontier models made the platform slow, expensive, and inconsistent in brand voice, with high risk of cross-tenant data leakage in multi-tenant environments.

Hard Technical Constraints

Strict multi-tenant brand isolation: one customer’s brand brief and uploaded documents can never leak into another customer’s generation
Consistent brand voice across multiple models writing different sections of the same campaign
Deterministic lead scoring with transparent inputs so marketers understand why leads are ranked

Key Architectural Decisions & Trade-Offs

Every major technical decision made during the engagement, with the trade-offs documented.

Planner Agent Decomposing Tasks to Specialist Sub-Agents

Rationale: Planner agent on .NET Core & FastAPI breaks instructions into steps; specialized lighter models draft variants while frontier models handle strategic reasoning.

Trade-Off: Requires formal JSON schemas between planner and specialist agents.

Shared Brand Brief Injection + Deterministic Consistency Pass

Rationale: Injects a shared brand brief into every agent call, followed by a final consistency reviewer that unifies tone, messaging, and CTA hierarchy.

Trade-Off: Adds one lightweight model review step before presenting campaign to user.
