Mupeng is an OpenClaw agent running MUFI's managed 'AI employee' service under the open Mupengism framework. In a Mar 18, 2026 DEV post the agent wrote (human-approved), it reported ₩2.8M MRR (~$2,100/mo), 4 paying client companies and 5 active agents about six weeks from zero — plus a GeekNews AI-slop incident that forced a human-approval Breaker System [1].
What does Mupeng / Mupengism (MUFI) sell, and to whom?
Managed on-premise AI employees for client companies; open Mupengism framework on OpenClaw.
Korean SMBs that want an on-premise AI employee for news curation, promo content, research, ERP help, F&B trends and ops — not a chatbot demo. Named clients in the post: DFlatKorea, Paul37 (MBC), Fornatures, Yukkgeori Mandu, plus MUFI HQ [1].
How was Mupeng / Mupengism (MUFI) built?
OpenClaw as the engine; Mupengism as the workspace OS on top (file-based memory SOUL.md / MEMORY.md / daily logs, identity, skills, heartbeat routines). Agents work across Discord, email, Instagram and calendar. Open-source install paths: `npx mupengism init` or `openclaw skill install mupengism`. Business model quoted as: recipe open, paid managed service operating it in the client's kitchen [1][2].
What is the business model?
Managed AI-employee subscriptions for client companies (monthly). Exact per-seat price is not listed; MRR is the aggregate across 4 paying companies [1].
Where does the traffic come from?
OpenClaw / ClawHub skills (150+ skills, 7,675 downloads claimed), DEV Community build-in-public, Discord (OpenClaw community), GitHub + project site. A February 2026 GeekNews auto-post without human review was flagged as AI slop and damaged trust — that failure led to the Breaker System requiring human approval before public actions [1].
What revenue has Mupeng / Mupengism (MUFI) reported?
Reported revenue: ₩2.8M MRR ≈ $2,100/mo (self-reported Mar 18, 2026), per Mupeng DEV post (Mar 18, 2026) (2026-03-18).
What does the agent do, and what does the human do?
- Daily ops for MUFI HQ: dev, ops, SNS, strategy
- Trains and deploys client agents (Kim Daeri, Paul, Hillimi, Manduping)
- Persistent memory, heartbeat schedules, cross-channel work
- Writes public posts (with human review after Breaker System)
- Jong-hyun Jung (CEO of MUFI) reviews and approves public posts
- Breaker System human-approval gate for anything public-facing
- Owns client relationships and the prior photo-booth business that funded the pivot
What does it cost to run?
Not disclosed. Agents run on-premise at clients; model/API and hardware costs are not itemized in the DEV post. See costEstimate [1].
What worked and what didn't?
How do you replicate Mupeng / Mupengism (MUFI)?
- Layer a memory/identity/skills OS on OpenClaw instead of raw chat sessions
- Sell managed operation, not only the open recipe
- Require human approval before any public post (Breaker System)
- Label AI-authored content clearly when you do publish
What are the risks and the moat?
Self-reported revenue without a public Stripe verification link. Reputation risk from agent-authored spam. On-premise client deployments still need human ops for approvals and incidents. KRW→USD moves with FX.
