Conservative, base, and aggressive scenarios across the same 24-month horizon.
| Assumption | Value | Justification | Source | Risk |
|---|---|---|---|---|
| Client acquisition rate | 3–4/mo | Founder-led + LinkedIn + referrals. 75-day B2B sales cycle. Requires ~15 SQLs/mo at 25% close rate. | GTM Playbook | Medium |
| Annual retention | 85% | SMB SaaS averages 80%. Annual contracts and ongoing model justify 85%. SMB churn can exceed 20% — this is the key risk. | SaaS benchmarks | Medium |
| Tier mix | 40/35/25 | Core attracts price-sensitive first-timers. Growth is the decoy-optimised target. Scale serves established clients. | Pricing analysis | Low |
| Blended ARPU | $882/mo | Weighted: ($660×40%) + ($940×35%) + ($1,350×25%) = $882. Rises to ~$924 after M9 increase. | Pricing architecture | Low |
| Gross margin | 63% | Bottom-up cost build: labour, platform, tools, founder allocation. Improves to 65–72% at scale with portal automation. | Cost model | Low |
| Blended CAC | $600 (Y1) | Starts ~$800 (paid-heavy) M1–3, converges to $400–500 as referrals and SEO scale. Founder-time included. | Channel data | Medium |
| Manager hire trigger | 15 clients | One manager handles 15–20 clients with portal automation. Cost: $4–6K/mo per manager. | Strategy Deck V2 | Low |
| No external capital | Bootstrapped | Revenue-funded growth with $62–102K initial investment. Seed round viable at 25+ clients with portal live. | Trend Intelligence | Medium |
| Metric | re/start (Base) | SMB SaaS Median | Top Quartile | Assessment |
|---|---|---|---|---|
| LTV:CAC | 17.6:1 | 3:1 – 5:1 | >6:1 | Exceptional Low CAC + high retention |
| CAC Payback | 2.1 months | 12–18 months | <6 months | Exceptional Among fastest in B2B services |
| Gross Margin | 63% | 50–65% | >70% | Good Portal automation should push to 70%+ |
| Annual Retention | 85% | 75–85% | >90% | Good Solid for SMB; target 88%+ |

| Magic Number (Y2) | 1.8 | 0.5–0.75 | >1.0 | Exceptional $1.80 ARR per $1 S&M |
Five conditions that should trigger immediate corrective action.
| Metric | Healthy | Warning | Action Required |
|---|---|---|---|
| New clients/month | ≥4 | 2–3 | <2 for 3 mo |
| Monthly churn | <1.5% | 1.5–3% | >3% |
| Blended ARPU | >$850 | $726–850 | <$726 |
| Gross margin | >60% | 50–60% | <50% |
| CAC payback | <3 mo | 3–6 mo | >6 mo |
| Cash runway | >6 mo | 3–6 mo | <3 mo |
$2.28M cumulative revenue, $1.59M exit ARR, break-even at month 8, no external capital required. The numbers support the strategy.
