Today's Startup Ideas

Fresh ideas from the latest trending topics — updated daily.

July 20

Prompt Purse

A local proxy that sits between your IDE and any LLM API (OpenAI, Anthropic, Groq). It caches repeated prefix prompts, compresses context by summarizing older messages, dynamically switches to cheaper models when confidence is high, and provides a real-time cost dashboard per project. Also auto-generates weekly waste reports.

Target audience

Freelance full-stack developers who pay out-of-pocket for AI coding tools like Copilot, Cursor, or direct API usage, spending $200+/month on tokens while building client projects, and lack visibility into what queries are expensive.

Why now

HN front-page post 'I burned all my tokens researching how to save tokens' and Dev.to 'I burned through thousands of AI tokens. Then a friend did it for free' this week. GitHub trending 'airllm' (compression) and 'ktransformers' (efficiency) show the technical feasibility of optimizing token consumption.

Agent Glass

A desktop app that runs locally and hooks into any AI agent framework (CrewAI, AutoGen, MCP servers) to capture full execution traces—thought chains, tool calls, API responses, token usage. Provides a visual timeline of reasoning, flags hallucinations or loops, and suggests cutoff points. All data stays on-device, unlike cloud-only observability tools.

Target audience

Individual developers building autonomous agents for internal automations (data entry, customer support bots) on their Mac/Linux, who currently litter their code with print statements and guess why agents fail because existing tools require cloud or complex setup.

Why now

Dev.to posts 'I got tired of not knowing what my AI agents were doing, so I built a tiny observability tool' and 'Building an AI Agent That Knows When Not to Guess' directly describe this frustration. GitHub trending 'cua' (agent framework) and PH 'AgentX' show the agent tooling wave, but none offer a local-first privacy-respecting solution.

IoT Patch Pipeline

A SaaS platform that scans IoT firmware for known vulnerabilities, generates signed OTA update packages, and manages rollout across device fleets with audit trails for FCC compliance. Automatically tracks CVEs and EOL components, alerting manufacturers when they must ship a patch.

Target audience

Small-to-mid IoT device manufacturers (5–50 employees) building home automation and wearables, who lack dedicated security teams and currently scramble to manually push binary updates via custom scripts when a vulnerability is publicly disclosed.

Why now

Ask HN: I’m an FCC Commissioner proposing regulation of IoT security updates this week signals imminent mandatory requirements. The ESP32 hacking trend (Show HN: replaced $120k system with $1,600 ESP32s) shows explosive IoT growth, but these makers can’t handle compliance.
