Day14 OS is the multi-tenant studio I built to run every business I own from a single worktree. Marketing sites, customer portals, billing, admin app, scheduled agents, an inbox that only surfaces things a human has to decide.
Today I’m opening the waitlist. The signal closes Sunday at 14:00 EDT.
I open the admin dashboard, the inbox shows me three things to approve, I approve them, the scheduled tasks fire, and by noon every business has shipped something. No team, no project manager, no Notion archaeology. The OS is the manager.
Demo recording in progress. Paste the Loom share URL into LOOM_EMBED_URL in page.tsx.
The OS is multi-tenant from the metal up. These three businesses share the same admin app, the same inbox, and the same evidence verifier. They look like three companies because they are.

Clinician portal — credential checklist + intake parser running over a candidate resume, dossier auto-generating into the right panel.
Result
Credential-aware intake that used to take 40 minutes per clinician now takes 4. Same admin app the operator uses for the other five businesses.

Brand site hero with menopause-positive editorial photography, product grid, MailerLite-wired waitlist, AI chatbot answering symptom questions.
Result
Brand-led D2C site built to look like it came from a 20-person team. Lives in the same OS as the SaaS tenant — different brand, same admin.

Article archive of 30+ drafts on an editorial template, with the scheduled-task panel showing the daily content agent's last run.
Result
A scheduled agent drafts essays nightly to the brand voice. Operator reviews and ships from the inbox. One content business running on autopilot.
Same OS. Same inbox. Same evidence verifier. Three completely different businesses.
One config entry. The OS picks up the tenant everywhere — admin dashboard, inbox routing, deploy strip, scheduled tasks, work-log.
Daily briefing, content drafts, image generation, deploy commit, EOD evidence check. Each agent writes to the work-log when it ships, surfaces to the inbox when it can't.
The operator's job is one screen: /admin/inbox. Everything else is either automated or evidence-verified. If it's not in the inbox, it doesn't need you.
Founder pricing locks for the first 100 signups. After that the Founder tier closes; Portfolio becomes the top public tier.
1 tenant
One operator, one business, wants the OS but only needs one slot.
Up to 5 tenants
One operator, two to five businesses. The shape this OS was built for.
Unlimited tenants
Heavy users. Onboarding session, direct line, closes at 100 signups.
No drip campaign · No upsell · Founder tier closes at 100 signups
If 50+ operators want this by Sunday at 14:00 EDT, I start onboarding next week. If fewer, I refocus on the strongest tenant and the OS stays private tooling. Either answer is useful. The point of the waitlist is to find out.
I’ll send one email Sunday with where the signal landed, and maybe one more on launch day. That’s the whole sequence.
No drip campaign. No upsell. Unsubscribe is a one-click reply.
The build studio that funded Day14 OS is still taking three customers a month. Fixed-price 14-day platforms — site, portal, admin app, billing. Same operator, same agents, different deliverable.
