SaaS CLI + hosted dashboard that audits activation steering vectors for cross-concept contamination, giving alignment researchers shareable leakage reports.

Independent alignment researcher or ML safety engineer at small lab (1-5 people) who runs steering experiments on local LLMs weekly, publishes findings, and needs reproducible evidence that their vectors aren't polluting adjacent concept dimensions — not a big-lab employee with infra team.

one-time $1,200 in one-time sales in month 3 (roughly 12 licenses at $99 each)

Audit tool that tells ML practitioners which training samples should get SFT vs RL updates—before they waste GPU budget on interference-damaged runs.

Independent ML engineer or small-team AI startup (2–5 people) fine-tuning reasoning models (e.g., Qwen, Mistral, DeepSeek) on domain-specific data—medical Q&A, legal reasoning, code—who runs training on rented A100s and can't afford to discover the SFT/RL interference problem after a $300 run.

Spatial Q&A SaaS for robotics hobbyists — upload a phone video, query the 3D geometry in plain English

Indie robotics hobbyist building a home assistant or pick-and-place robot — someone spending weekends on ROS2 stacks who keeps hitting a wall when their robot needs reliable relative-position answers ('is the mug left or right of the kettle?') and doesn't want to fine-tune a vision model

A CLI tool that scores arXiv papers for genuine novelty against your personal reading history, so researchers stop re-reading recycled ideas

Solo ML researcher or technical lead at a seed-stage AI startup — reads 15-25 papers/week on arXiv, tracks papers in Notion or Zotero, constantly annoyed that 40% of papers are incremental tweaks on things they already know cold

Sell CoT Graph Compressor as a token-cost reduction tool for AI teams burning money on long reasoning chains

A SaaS tool that lets solo devs and small AI teams record, tag, replay, and diff agent trajectories to catch prompt-regression bugs without re-running expensive benchmarks.

Indie AI developer or solo founder who has shipped at least one LLM-powered agent to production (e.g. a coding assistant, research bot, or support agent) and is now iterating on prompts/tools weekly — and keeps accidentally breaking behavior they fixed two weeks ago.

From project: Agent Behavior Pattern Library (ADRA-Bank Clone)
