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
  • Report without decks: the cockpit, dashboards, and report views your client can check any day of the quarter
  • 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.

Bring your next client onto the OS.
