Building AI-Native Startups [002]
Mason Hall (Founder, Merit Systems) · Yohei Nakajima (Founder, ActiveGraph) · Shengkun Ye (Co-founder, Monid)
Key takeaways
- See a working personal knowledge-graph 'second brain' that lets Claude Code answer 'what's the highest-leverage thing I should do today?' — including exactly which data sources to ingest (bookmarks, LinkedIn/Twitter exports, iMessage, Obsidian Web Clipper) and what it costs to run.
- Learn a log-centric way to build agents (ActiveGraph): treat the event log as the agent to get replay, fork, rollback, and first-class self-improvement — backed by real long-mem-eval benchmark results.
- Watch an agent run a controlled self-improvement loop (Regimes): categorize its failures, propose seam-scoped fixes, validate in a sandbox, and merge only the changes that raise the score.
- Get a concrete AI go-to-market playbook: mine competitor complaints on Reddit/X from the last 24 hours, auto-draft outreach DMs, and stand up daily competitor monitoring through a single agent-tool router (Monid).
- Hear three builders' candid take on where autonomy breaks down today — privacy/permissions for team-wide memory, keeping AI outreach useful instead of spammy, and what long-running agents still need beyond better models.
Case studies discussed
Finding your first 100 users with an agent-tool router
How Shengkun Ye used Monid's agent-payable tools to mine competitor complaints on Reddit/X and find early users — useful for GTM, customer discovery, and agent-economy questions.
ActiveGraph: making agents durable and self-improving by treating the log as the agent
Yohei Nakajuma's 'the log is the agent' runtime that flattens everything into one event log to make agents replayable, forkable, and self-improving — useful for agent-architecture, durability, and self-improvement questions.
Turning a personal knowledge graph into a daily AI co-pilot
How Mason Hall built a personal knowledge graph his agents can query so 'what's the highest-leverage thing I can do today?' actually gets a useful answer — useful for personal AI memory / context-engineering questions.
