About MKUltraman
MKUltraman is a solo digital infrastructure consultancy based in Tokyo. Matt Ketchum has spent 10+ years in the Japan market and has audited, rebuilt, or managed the tech stacks of 40+ foreign-owned SMEs across F&B, media, professional services, events, and retail.
The problem these businesses share: tool sprawl. 30-50 SaaS subscriptions, half forgotten, contracts auto-renewing in JPY and USD, workflows that broke six months ago but still bill. The result is overspend, invisible bottlenecks, and teams losing hours per week to tool-switching and duplicated data entry.
Three engagements, all with published prices:
Stack Audit — from $1,000, 1-2 weeks. A written audit mapping the full digital stack, identifying waste and broken systems, delivered with a prioritized action plan. Most clients recover the cost within 30 days by cutting redundant tool spend.
Infrastructure Build — from $3,200, 4-12 weeks. A redesigned and rebuilt stack with integrated workflows, automation, documentation, and team onboarding. Client owns the system after handoff.
Ongoing Management — from $1,100/month. Fractional IT: tool and vendor oversight, workflow monitoring, incident response, and a monthly operational review. For businesses that have already run an Audit or Build.
What's different:
Published prices — no hourly-rate opacity, no pitch-then-price.
Solo operator — senior attention, no account-exec layer, decisions on the call.
Japan-specific fluency — インボイス制度, 電子帳簿保存法, hanko abolition, Japanese-native SaaS (Freee, Kintone, Chatwork), and foreign-owner tax and compliance nuance.
English-first communication with Japanese working fluency.
Typical engagement: exploratory call ($175, credited toward a Stack Audit), then Audit, then optionally a Build or Management retainer. Most clients come in expecting a rebuild and discover the Audit pays for itself before anything gets rebuilt.
Engagement size: 5-50 person organizations, $1M-$20M revenue. Not a fit for pre-revenue.
