For fractional CMOs
The one-person agency, fully staffed.
Your clients hired senior judgment. T2D3 OS makes the execution underneath it look like a full team — strategy, content, design direction, web, and reporting — without the payroll.
Where the OS earns its keep
- Win the engagement: run the free Website Compass on a prospect and open the first meeting with their scored GTM diagnosis
- Land fast: onboard the client workspace, run the GTM survey and interviews, and lock the foundation in the first weeks
- Deliver weekly: playbook modules draft plans, scorecards, and content grounded in that foundation — you review, edit, lock, and ship
- Never write the follow-up again: Engagement Notes records the client call — Teams and Zoom audio included — and hands you the decisions, the assigned action items, and the follow-up email before you have closed the tab
- Report without the deck busywork: the cockpit, dashboards, and report views your client can check any day of the quarter — and the deck assembles itself when you do need one
- Scale yourself: pull a Sculptor into the rebrand or a Scribe into the launch from the marketplace — no hiring
The economics of one
One platform replaces the AI stack, the project tool, and the reporting layer — and every engagement's judgment compounds inside the OS instead of evaporating between tools. A single retainer covers your entire practice, with every client in its own workspace under one login. Here's the arithmetic:
What you're paying now vs. what you'd pay here
Your current stack, itemized at typical solo-operator pricing. Every one of these bills separately — and none of them share your client context, so every hand-off between them is unbillable glue work.

The bigger number is your time. At a $10K retainer and 20 billable hours a month, your hour is effectively $500. Recover four hours of unbillable glue work per client per month across three clients and that's ~$6,000 of billable capacity back — several times the Agency tier, before counting a single cancelled subscription. Those are our assumptions, not yours: Swap in your own numbers in the ROI calculator →
Built by someone who did the job
T2D3 OS comes from Stijn Hendrikse, who has done this job since before it had a name: he went fractional in early 2015, helping Atera's founders stand up their first marketing — Atera went on to become a unicorn. When Chief Outsiders drove the term into the mainstream, he joined in 2016 as their first B2B-SaaS-focused fractional CMO, then co-founded Kalungi, the fractional-CMO agency for B2B SaaS, and wrote the T2D3 and Syntropy books. The OS is the system a fractional CMO practice actually runs on, productized.
