Demand Forecasting API ·

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

If you land 65 paying customers at $100/mo average by month 12, that's $78k ARR - but AWS Forecast will undersell you on day one and cold-start trust issues will kill 70% of trials; honest odds of getting there are around 1 in 8.

~50,000 US mid-market e-commerce and retail companies ($1M-$100M revenue) spending ~$3,600/yr on inventory optimization tooling, where an API product can realistically compete against spreadsheets and legacy ERP add-ons.

Go-to-market motion

Outbound LinkedIn to e-commerce Ops/Supply Chain leads at Shopify/WooCommerce merchants → offer free 30-day accuracy trial on their own historical data → convert to $500-$1,500/mo subscription when forecast beats their current method.

Key risks

AWS Forecast, Google Vertex AI Forecast, and Azure ML offer demand forecasting as a commodity service with massive infrastructure advantages - price and trust undercut any indie API instantly.
Cold-start credibility problem: buyers won't pay until they see your model outperform their existing system, but a meaningful accuracy test requires 12-24 months of their historical data and a long evaluation cycle.
Deep integration burden falls on the buyer - connecting to their ERP, POS, or inventory system is weeks of engineering work, killing conversion in the SMB/mid-market segment where eng bandwidth is scarce.
