How It Works
Search once. We keep searching for you.
105,000+ vetted suppliers, 1,000+ updated every day. Nearly 40 years of sourcing data, supplier-submitted catalogs, and AI deep research — working together to find your parts.
Search
One search box queries categories, parts, brands, and companies simultaneously. No filters to configure.
Instant Results
Matches from 105,000+ vetted suppliers appear in seconds. Unlock to see contact details. Your search keeps running after you close the tab.
Deep Research
Every search triggers our AI deep research system — multi-round investigations across manufacturer sites, distributor catalogs, and broker networks. Each finding is evaluated, verified, and quality-reviewed before it reaches your results.
Notification
Every time a new supplier is found for your search — whether it's hours, days, or months later — we email you. Your search never expires.
Three sources. One search.
Every search queries all three simultaneously.
40 Years of Sourcing Data
Nearly 40 years of sourcing relationships. 105,000+ companies across aerospace, telecom, defense, energy, and manufacturing. Built one deal at a time.
Verified Supplier Profiles
Suppliers and manufacturers list their parts directly. Free to list, reviewed before publication. Keeps inventory data current from the source.
Deep Research + Human Review
Every search triggers our deep research system. Research agents conduct structured, multi-round investigations — analyzing industry databases, manufacturer sites, distributor catalogs, and broker networks, then cross-referencing company details and validating that suppliers actually carry the parts they claim. Research is automated, verification is human, before publication. Over 1,000 companies are updated, enriched, or added every day as the research runs. A search today can surface new verified suppliers months later.
We’ll let you know.
When our research finds new sources relevant to your search — whether that’s hours later or a year later — we send you an email with what we found. No spam, no newsletters — just results.

How accurate is the supplier data?
Every user search triggers AI deep research that updates and enriches company records in real time. Over 1,000 companies are updated, enriched, or added every day. Contact information changes — companies move, numbers get disconnected, emails change — so we recommend verifying current details directly with the supplier before placing orders.
How is 3E different from Octopart, ThomasNet, or FindChips?
Octopart and FindChips search select distributor inventory for real-time stock and pricing. ThomasNet lists suppliers who registered themselves. 3E indexes 105,000+ companies including brokers, surplus dealers, and specialty distributors that don't appear on those platforms, and our deep research system keeps hunting for new sources after you search. Different problem, different tool.
Do I need a subscription to get notified?
No. Any registered user receives alerts when new suppliers are found for their searches. Every account gets 5 free unlocks per month. Beyond that, credit packs and unlimited subscriptions are available — see our pricing page.
Can I search by category or keyword instead of a specific part number?
Yes. You can search for categories like "power supplies," "MIL-spec connectors," or "industrial sensors" — not just part numbers or company names. The research runs on every query and notifies you when new suppliers appear.
What if I search for something you don’t have yet?
Your search starts AI deep research in the background immediately. We hunt across broker sites, surplus dealers, and specialty distributors worldwide for anything that matches your query. When a verified supplier surfaces — an hour from now or six months from now — we email you. Your search never expires, so a match next year still reaches you.
Can I export my unlocked data?
Yes. Your unlock history is saved permanently to your account, and you can export it from your dashboard at any time. The export includes contact details — phone numbers, emails, website URLs, and addresses — for every supplier you've unlocked.
