7 STARTUP IDEAS IâD BUILD USING CLAUDE AGENT SDK/CLAUDE OPUS 4.5:
1. SOC 2 / ISO compliance packet agent for saas
Agent that reads a SaaS companyâs policies, infra docs, and tickets, then assembles SOC 2 / ISO audit-ready evidence. Iâd connect the SDK to Linear/Jira, Notion, GitHub, and GDrive, load in standard SOC 2 templates, and have it produce checklists, evidence folders, and draft responses for auditors.
2. Nonprofit grant writing agent
Agent that finds relevant grants, drafts tailored applications, and organizes all deadlines for a nonprofit.
Iâd plug Claude Agent SDK into a grants database + Google Drive, feed it past successful applications, and have it generate full packets and follow-up tasks for the team.
3. Airbnb host operations agent
Agent that responds to guests, coordinates cleaners, handles pricing tweaks, and generates monthly summaries. Iâd wire the SDK into Airbnbâs API (or inbox), Google Calendar, and a cleanerâs scheduling tool, then give it workflows for messaging, scheduling, and simple pricing rules.
Who knows. Maybe this gets acquired by Airbnb.
4. Shopify conversion/creative agent
Agent that reviews a Shopify store, analyzes analytics, and ships specific CRO fixes plus ad creative. Iâd hook the SDK into Shopify, Google Analytics, and a simple image/video tool, then have it propose changes, write new copy, tag winning products, and draft UGC-style ad scripts.
5. Real estate deal coordinator agent
Agent that keeps a real estate deal on track: chasing documents, scheduling inspections, reminding clients, and tracking key dates. Iâd connect the SDK to email, e-signing, calendar, and a simple deal tracker, then give it a closing checklist so it runs the communication and nudges.
6. YouTube research + script agent for creators
Id love this.
Agent that researches topics, pulls data, builds outlines, and drafts long-form scripts based on a creatorâs style. Iâd give the SDK access to YouTube, Google, and a library of past scripts, then have it return a ready-to-record outline with hooks, segments, and CTAs.
7. Agency âBrainâ and Onboarding Agent
Agent that absorbs an agencyâs SOPs, past projects, and Slack history, then answers questions and ramps new hires. Iâd load all docs through the SDK, connect it to Slack and Notion, and give teammates a chat interface where they can ask âhow do we do X?â and get step-by-step answers plus links.
BONUS IDEA:
Insurance claims prep agent
Agent that helps people prepare insurance claims by collecting photos, receipts, timelines, and forms into a clean packet adjusters love.
Iâd probably hook the SDK into email, cloud storage, and a claims-template library, then have it assemble everything automatically and flag missing items.
TLDR;
The Claude SDK acts like a full operating system for agents memory, tools, workflows, everything.
These ideas were just something to get your creative juices flowing.
Happy building.
