BOM RISK MONITOR

Know before your BOM breaks.

ShareCo watches every part on your BOM across Digi-Key and Mouser. The moment a chip goes EOL, your stock drops below threshold, or a lead time blows out, you know.

Watch your first BOM Read the technical writeup

The spreadsheet breaks quietly

BOM risk does not announce itself.

A part went EOL three weeks ago.
You're still ordering it. The manufacturer sent one notice. It went to an inbox nobody reads.
Your MCU just hit allocation.
Lead time went from 8 weeks to 26. Your next production run was supposed to ship in 10.
Your BOM cost is wrong.
Distributors hike prices quietly. Your spreadsheet has the old price from six months ago. Margin gone.

WHAT IT DOES

It watches. It alerts. It suggests alternates.

Every part on every BOM checked daily against the canonical distributor sources. When something changes, you get a notification that's readable on your phone in 5 seconds. When a part fails, GPT-5.5 ranks pin-compatible alternates from the same distributors.
