Pricing

What Phronimos charges, on one page.

Three engagements, in one order. A $999 Agent Reliability Review answers whether what you already built is actually working. An Agent Implementation Sprint from $3,500 puts one painful workflow into production, with testing, guardrails, and a documented handover. A $5,000 / month Fractional AI Officer retainer keeps it running and adds the next one. Each one is fixed-scope, priced before it starts, and re-priced in writing if scope changes during the work. The review fee is credited forward, so anyone who goes on to build effectively gets the diagnosis free.

The review fee is credited in full toward an Agent Implementation Sprint or the first month of a Fractional AI Officer retainer.

$999

Agent Reliability Review

Is what you already built actually working?

Best for: Owners who have already bought or built AI agents, workflows, or automations and are not sure whether they still work.

A written diagnosis mapped to the four silent-failure modes, evidence per finding, and a monitoring posture so the next failure gets caught before your customer sees it.

Build one

From $3,500

Agent Implementation Sprint

Put one painful workflow into production.

Best for: Owners with a specific workflow scoped and ready to ship — auth in place, inputs identified, escalation path agreed.

One workflow becomes measurably faster and less owner-dependent, with testing, guardrails, and a documented handover.

Keep it running

$5,000 / month

Fractional AI Officer

roughly one junior FTE, without the hire

Best for: Owners who have one or more agents in production and want an accountable operator layer without hiring for it.

AI adoption becomes a line in the operating budget with an owner attached, monitoring for the four silent-failure modes, and a queue you can see into.

What's included at each tier?

The comparison below reads left-to-right as the natural sequence: diagnose, build, run. Most engagements begin at the review because the diagnosis is credited forward. Some skip straight to a sprint or the retainer when the workflow is already scoped.

How the pricing works

What's included in the review?

A 45-minute working call with whoever owns the workflows, a diagnostic run against the four silent-failure modes (bad output on green status, dropped webhooks, stalled triggers, downstream data loss), per-workflow findings with evidence and blast-radius numbers, a remediation plan with hours-of-effort per fix, and a monitoring posture recommendation. Two weeks from kickoff. About 90 minutes of your time.

How does the sprint work?

One workflow is designed, built, tested against live examples, and handed over with guardrails, escalation paths, an SOP, and a team training session. The scope is agreed before work starts and the price is fixed to that scope. If scope changes during the work, it gets re-priced in writing before continuing. Sprints run 4–6 weeks. Complexity moves the price above the $3,500 floor; the number is agreed up front.

What does the retainer include?

One to two active requests at a time, an under-48-hour turnaround target, monitoring for the four silent-failure modes, incident response against the published reliability standard, maintenance and tuning of what's already running, new-workflow rollout at retainer pace, a customer-facing request queue, async video updates, and a monthly report. Priced flat at $5,000 / month, month-to-month, 30-day notice.

How does the credit-forward mechanic work?

The $999 review fee is credited in full toward an Agent Implementation Sprint or the first month of a Fractional AI Officer retainer. For anyone who goes on to build, the diagnosis is effectively free. If the findings point nowhere, the report is still yours to use — the review has already paid for itself by preventing a build that would have failed.

What isn't priced on this page?

Engineering time on custom software builds, third-party subscription costs (model APIs, automation platforms, integration tools — passed through at cost), and any work outside the agreed scope of a specific engagement. Those get priced separately, in writing, before they start.

Is there a minimum term on the retainer?

No. The retainer is month-to-month with 30-day notice on either side. The commercial promise rests on the monthly report showing what changed, not on a lock-in.

Two calculators to make the case internally. The formulas are visible on each page — no email gate, no accounts.

  • Workflow ROI calculator

    Given the hours a workflow eats each week and the fully-loaded cost of the person doing it, computes annual dollars saved if it were automated and months to break even against the $3,500 sprint.

  • Cost of a manual process

    Given volume per month, minutes per instance, and a loaded hourly cost, computes the hours per month and the annual dollars tied up in the process.
