gi-log: Persistent Session Memory for Claude Code

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

If you land 240 paying devs at $10/month, that's $28.8k ARR - but Anthropic is one blog post away from making this irrelevant, so honest odds are 16% you get there before they do.

Market size (TAM)

$1.5M

~250k active Claude Code developers globally × ~5% willing to pay for session memory tooling × $10/mo avg × 12 months

Year-1 ARR range

$6k - $108k

midpoint $29k

Gross margin

92%

Investment to production

$9k

Dev: $3k for auth, billing (Stripe), and storage backend. Landing page + SEO: $1.5k. Community seeding + sponsorships in Claude/dev Discord/

Probability of success

16%

P(reaching mid case in 12 months)

Expected take-home Y1

$-4762

probability-weighted, after investment

Go-to-market motion

PLG via Claude Code subreddit, Hacker News, and X developer communities → free tier with storage cap → 3-5% convert to paid $9-12/month; no outbound viable at this price point.

Key risks

Anthropic ships native persistent memory directly in Claude Code (already on their public roadmap), instantly zeroing the product's core value proposition
Developer audience has zero tolerance for paying for tools they can replicate with a 50-line shell script or open-source MCP server - free/OSS alternatives already exist on GitHub
Platform dependency is total: if Anthropic changes how Claude Code sessions work or restricts third-party hooks, the product breaks with no fallback
