Rates & Engagement Scope Guidance
Review our transparent advisory fee structure for independent A/B test audits, pre-experiment power sizing, telemetry diagnostics, and quarterly retainer engagements.
Advisory Engagement Pricing Models
At Flow Harbor Point, our fees reflect the depth of quantitative analysis, sample complexity, and dedicated practitioner hours required to rigorously verify your experimental data. We do not offer automated self-service software or recurring platform subscriptions; every engagement is an independent, human-delivered professional consultation resulting in signed mathematical briefs.
All rates are informational and quoted in USD. Formal scope proposals are provided following an initial review of your dataset dimensions and decision timeline.
Standard Engagement Fee Schedule
1. Flagship: Comprehensive Experiment Result Audit
- Typical Fee Range: $3,400 – $5,800 per experiment dataset
- Engagement Duration: 3 to 5 business days
- Scope Basis: Up to 5 million unique assigned experimental entities and up to 10 secondary/guardrail metric streams.
- Deliverables: Complete telemetry sanitization, SRM chi-square diagnostics, CUPED variance reduction modeling, Dual Frequentist/Bayesian bounds, 18–25 page signed Verification Brief, Executive Decision Memo, and 60-minute technical presentation.
2. Pre-Experiment Power Sizing & Variance Modeling
- Typical Fee Range: $1,800 – $2,900 per testing protocol
- Engagement Duration: 2 to 3 business days
- Scope Basis: Historical baseline variance analysis (30–90 days data), mathematical sample size calculations across multiple MDE scenarios, Dunnett/Bonferroni multi-arm allocation plans, and seasonal runtime specifications.
- Deliverables: Experiment Sizing Blueprint, parameter workbook, and hypothesis design review session.
3. SRM & Telemetry Forensic Diagnostic
- Typical Fee Range: $2,200 – $3,600 per investigation
- Engagement Duration: 2 business days
- Scope Basis: Urgent forensic analysis of an active or concluded test exhibiting sample allocation skew or tracking anomalies.
- Deliverables: Sub-cohort stratification report (OS, device tier, geo, network latency), root-cause telemetry audit memo, and engineering remediation guidance.
4. Guardrail & Multi-Metric Portfolio Analysis
- Typical Fee Range: $2,600 – $4,200 per multi-variant suite
- Engagement Duration: 3 business days
- Scope Basis: Comprehensive statistical evaluation across primary conversions, technical health metrics (crash rate, API latency), and cohort retention.
- Deliverables: Interaction Risk Matrix, Benjamini-Hochberg FDR adjustments, non-inferiority confidence bounds, and rollout threshold rules.
Retainer & Ongoing Advisory Engagements
For engineering and product organizations managing continuous testing pipelines across multiple feature teams, we offer dedicated Quarterly Statistical Advisory Retainers:
| Retainer Tier | Monthly Inquiries / Audits | Dedicated Reviewer | Monthly Advisory Fee |
|---|---|---|---|
| Standard Advisory | Up to 2 Full Audits + 4 Sizing Reviews | Senior Statistical Consultant | $6,800 / month |
| Comprehensive Advisory | Up to 4 Full Audits + Unlimited Sizing | Lead Methodologist (Dr. Vongviphas) | $12,500 / month |
Retainer agreements are committed on a quarterly (3-month) basis and include priority 48-hour audit turnarounds and standing weekly office hours.
Scope Estimation Factors
When preparing an engagement quote, our team evaluates several operational parameters:
- Total Sample Volume & Entity Count: Experiments with extreme scale (>10 million rows) or micro-second level telemetry logs require additional ingestion and distributed compute cycles.
- Metric Complexity & Distribution Shape: Binary conversion metrics require simpler modeling than zero-inflated continuous revenue metrics or ratio metrics requiring Delta Method variance expansion.
- Number of Experimental Arms: Multi-cell tests (e.g. 5 variants vs Control) necessitate multi-comparison family-wise error adjustments and complex covariance matrices.
- Urgency & Turnaround Requirements: Standard delivery is 3 to 5 business days; accelerated 48-hour rapid turnaround is available upon request subject to scheduling availability.
Payment Terms & Engagement Protocols
- Deposit & Milestone Schedule: Project-based engagements require a 50% deposit upon contract execution and data intake sign-off, with the remaining 50% due upon delivery of the final Verification Brief.
- Confidentiality: Mutual Non-Disclosure Agreements (NDAs) are executed prior to any data transmission.
- Payment Methods: Wire transfer (SWIFT) or international commercial invoice. All pricing is informational and subject to formal written agreement.
