Business Economics & Unit Economics Deep Dive
April 2026 — For Internal Use Only
At $249/month with ~$43 in variable costs, each family contributes $206/month to cover fixed costs and generate profit. The key metric: human time per family per month. If we keep this below 0.10 hours in steady state, the economics are exceptional at any scale.
FSRs are variable costs — they scale with families. Fixed costs are the corporate team that exists regardless of family count.
Engineers $250K · Org mgmt $200K · Ops $110K (1 per 2,500 families)

| FSR labor allocation | $26.04/family |
| AI / cloud | $5.00/family |
| Shared infrastructure | $4.00/family |
| Payment processing | $7.47/family |
| Total per family | $42.51/mo |
Each family contributes $206/month after variable costs. The break-even point is: Fixed Costs / $206 contribution margin.
An FSR does both jobs — onboarding new families and managing their ongoing panel. We calculate capacity for each demand type separately so we can see which workload is actually driving headcount at any point in the ramp.
Driven by new families per month.
160 hrs/month total · 50% allocated to onboarding = 80 hrs/FSR/mo
At 6 hrs/family → ~13 new families per FSR per month
Driven by total active families and outreach intensity.
80 hrs/FSR/mo for panel · at 8% outreach × 40 min/touch = ~0.053 hrs/family/mo
→ workload supports ~1,500 paneled families per FSR
Required FSR pool = whichever demand is binding
Under a cross-trained model, we size the pool to the larger of the two demands rather than adding them. During growth phases, onboarding throughput is typically the binding constraint. As the installed base grows, panel demand can overtake it — and that crossover is where AI tooling (reducing panel demand hours per family) creates the most leverage.
| New / Month | Onboarding FSRs needed | Active Families (M12) | Panel FSRs needed | Required FSR pool |
|---|---|---|---|---|
| 75 | 3 | ~800 | 2 | 5 |
| 150 | 6 | ~2,250 | 6 | 12 |
| 250 | 10 | ~4,450 | 11 | 21 |
| 500 | 19 | ~9,500 | 24 | 43 |
250 new/month (highlighted) is our Phase 3 target. Active family count assumes 2% monthly churn and ramp-up. Panel FSRs needed calculated at 8% outreach × 40 min handle time.

0.5% churn change = ~$2K LTV swing and ~500 family difference at Year 3.
These are the assumptions the model is most sensitive to. Each one has a concrete test and a timeline for getting an answer.
Section II
Each scale is a viable business. The question is which one we're building toward.
A profitable, founder-controlled company. ~40 people. $13M ARR. Strong cash generation by Year 3.
A market leader with health plan partnerships. ~48 people. $30M ARR. Regional expansion.
A category-defining platform. 200-400 people. $150-300M ARR. National presence.
36-month plan outcome. Self-funded, founder-controlled. Team: 5 eng, 8 mgmt, 22 FSRs, 1 ops = ~40 people.

6 hours × ($125K ÷ 1,920 work hrs/yr)
+ $600 acquisition cost*
= $990.63 total CAC
*$600 acquisition cost is a planning estimate — not yet validated. Actual CAC could range from $200 (referral-driven) to $1,500+ (paid digital). This is a key variable to test in Year 1.
$500 onboarding fee collected upfront
Remaining $490.63 recovered via subscription margin over ~2.4 months
Reducing onboarding from 6 to 3 hours
= $625K/year in salary savings. Halves onboarding headcount.

| Structural (1.67%) | Natural end of ~5-year care journey: death, facility transition, estate resolution |
| Voluntary (0.33%) | Dissatisfaction, affordability, switching to alternatives |
| Active Families | Lost / Month | Lost / Year | Replace / Mo |
|---|---|---|---|
| 1,000 | 20 | 240 | 20 |
| 5,000 | 100 | 1,200 | 100 |

| 50,000 | 1,000 | 12,000 | 1,000 |
At 10K families, 200 of every month's onboardings are just replacing churn. Growth requires intake above this replacement floor.
