FIG. 00 / POSTURE
ATHANOR is an AI-native operating studio. Three modes from one vessel: ventures we own, founders we embed with, engagements we take by hand.
FIG. I / READINGS
Live readings from the studio floor.
We run the studio out loud: continuous instruments, not a marketing dashboard. Telemetry from the work as it happens.

The vessel holds three modes at once. PL. 0A / IX
FIG. II-IV / THE THREE MODES
One studio. Three modes.
Most studios choose one posture: venture builder, embedded operator, or strategic advisor. ATHANOR holds all three because worthwhile company-building often needs more than one. The difference is clearest side by side.
FIG. II
Studio
Ventures we own and operate. Built inside the studio, financed off our own balance, released only when the cycle is complete.

FIG. III
Partners
Founders we embed with. We become a missing co-founder for 6-18 months, on the operating side, with skin attached to outcomes.

FIG. II / STUDIO / LAPIS
"Six ventures on our balance sheet. Released only when the operating wiring stands without us."
FIG. II / STUDIO MODE
Ventures we own and operate.
The studio's first mode. We hold the cap table, finance the first build cycle, run the operation, and release each venture only when it can stand without us.

FIG. III / PARTNERS / SAFFRON
"Eleven embedded teams. Four days a week each, for 6-18 months. Then we step out."
FIG. III / PARTNERS MODE
Founders we embed with.
The studio's second mode. We become the missing operating co-founder: four days a week, equity-aligned, for a constrained window. Then we step out and the company keeps its shape.

FIG. V / READING ROOM
The reading room.
Two rhythms: quarterly editions and daily fragments. Editions are the long account. Fragments are notes from the floor. Both are open. Neither is gated.

On the inflection where a founder stops being the bottleneck, and what we changed at Ferrum, Lyra Labs, and Saffron Capital to get there. With three case readings.

Pricing rewrite for Quill. Three tiers became one: $48/seat/mo, no annual lock, no enterprise tier. Conversion this morning: 6 of 14 trials.
Ferrum closed its Series A - $14M, Index lead. Embedded since Jan 2024. We step out at month nine; the operating wiring stays in place.
Reread Christopher Alexander, Vol. II, pp. 412-430 - on patterns that survive the death of their authors. Reused for a hand-off doc this afternoon.
A founder asked when a venture is finished. We use three criteria: founder runway greater than 18 months, decision velocity flat for two quarters, no remaining open loops on the studio side.
FIG. VII / PRICING
Clear terms before heat.
The operating model is simple: Studio is ownership, Partners is embedded operating capacity, Works is a fixed intervention. No vague advisory. No endless retainers. No misaligned incentives.
Studio
No service fee
For ventures formed inside Athanor or spun out from an operating thesis. We supply capital, product, engineering, go-to-market, and company formation.
- Shared ownership, not an invoice.
- Athanor funds the first build cycle.
- Formation terms are set company by company.
Discuss terms -> VII.01
Partners
$18k-$42k / month + equity
For founders who need an operating co-founder for a constrained window. Four days a week, 6-18 months, with a release plan from day one.
- Monthly operating retainer.
- Equity or warrant alignment.
- Maximum fourteen embedded teams at once.
Discuss terms -> VII.02
Works
$45k-$160k fixed scope
For teams already underway who need one sharp intervention: strategy, instrumentation, capital architecture, hiring, or editorial systems.
- Six- to twelve-week scopes.
- One named partner accountable.
- No retainers and no vague advisory.
Discuss terms -> VII.03
What changes price
Surface area, urgency, and whether Athanor carries outcome risk.
- Product and engineering ownership increases scope; advisory conversations do not.
- Equity alignment lowers cash requirements only when the operating risk is real.
- Anything under six weeks is usually a workshop, not an Athanor engagement.
