Every MasterOS engagement is scoped on the hours of senior consulting effort required to design, build, and ship your PersonalOS — billed at a flat S$200/hour. No per-user fees. No surprise add-ons. The tier you pick is the price you pay.
Each tier is a fixed-fee package built around a target hour budget. If your scope falls between tiers, we'll quote a custom hour allocation at the same S$200/hour rate.
Solo founders, consultants, professionals
A focused PersonalOS for a single operator — inbox, calendar, brief, and one revenue-critical workflow codified into agents.
Founders with a small team (2–10)
The MasterOS flagship build. A multi-agent stack covering executive ops, sales, content, and knowledge — wired into the tools your team already runs on.
Multi-function execs, agencies, growing firms (10–50)
A department-spanning PersonalOS. Agents for ops, sales, marketing, finance, and delivery — with cross-functional orchestration and role-based access.
Professional firms, agencies, regulated industries (50+)
Custom PersonalOS infrastructure for organisations with compliance, security, and multi-team orchestration requirements. Scoped per engagement.
The same engineering discipline runs through every tier — only the scope, agent count, and integration surface expand.

Every tier is the product of a scoped hour budget and our flat senior rate. Here's how the numbers actually break down.
Operating-system mapping, decision-flow interviews, ROI baselining.
Agent topology, integration design, knowledge schema, SOP outlines.
Agent engineering, automation pipelines, dashboards, QA.
SOP documentation, team enablement, tuning, post-launch support.
Engagement fee = scoped hours × S$200
We do not bill by seat, by agent, or by month. You're buying a fixed quantity of senior consulting effort, and you keep everything we build — code, prompts, documentation, SOPs.
Post-launch monthly retainer for ongoing optimisation, new agent rollouts, model upgrades, and workflow tuning. Available after any build tier. 25 hours of senior effort each month at the same S$200/hour rate. Pause or cancel any month.
It's the senior consulting rate Fabian carried out of Deloitte, adjusted for two decades of operator experience and an AI-native delivery stack. It's deliberately below Big-Four day rates but above generic developer pricing — because you're paying for diagnosis and architecture, not just code.
We quote a custom hour allocation at the same S$200/hour rate. Most custom scopes land between Operator (100 hrs) and Executive (200 hrs).
No. You pay the engagement fee, you own everything we build. Third-party tool costs (OpenAI, Anthropic, your CRM, etc.) are passed through at-cost on your accounts.
50% on engagement start, 50% on launch. Enterprise engagements are milestone-billed. Retainers are billed monthly in advance.
Yes. Foundation clients regularly graduate to Operator or Executive as their team and workflow surface grows. Prior hours are credited toward the upgrade.
A 30-minute scoping call is the fastest way to size your PersonalOS. We'll map the hours required before you commit.
