If an entrepreneur "adopted" this product today, here's the realistic math.
Fermi summary
If you grind to 200 paying engineers at $25/mo, that's $60k ARR - but there's only a 14% chance you get there in year 1, and you'll be in the hole on investment until month 8 at best.
Market size (TAM)
$58.0M
~120k US structural/civil/mechanical engineers at small-to-mid firms who document calculations for code compliance × $480/yr avg spend on niche calculation tools
Year-1 ARR range
$11k - $240k
midpoint $58k
Investment to production
$27k
Dev: $10k for auth, billing, team accounts, PDF export, and polishing AI explanation quality. Content/SEO: $8k for calculation-specific land
Probability of success
14%
P(reaching mid case in 12 months)
Expected take-home Y1
$-20800
probability-weighted, after investment
Go-to-market motion
SEO on specific calculation types (e.g. 'beam deflection calculator with steps') → free trial → $25/mo individual or $120/mo firm seat, targeting small structural/MEP consulting shops.
Key risks
- Excel + hand-typed comments is the deeply entrenched incumbent - engineers at firms are trained on it and switching requires justifying the tool to a PE who stamps the work
- Liability gap: engineers may not trust or legally be able to rely on AI-generated explanations for code-compliant submissions without independent verification, undermining the core value prop
- Calculation scope fragmentation - a civil PE's needs differ radically from an electrical or mechanical PE, forcing expensive vertical-specific depth before the product is truly sticky in any one discipline
- Thin differentiation from Mathcad and similar tools that already export annotated calculation reports - buyers will ask 'why not just use what our firm already licenses'
