Due diligence on a new contact before you commit
A new supplier, partner, or client reaches out by email. A two-minute footprint check tells you whether the person behind the address is who they claim.

Before a contract, an investment, or a first big payment, you do diligence on the company. The person emailing you deserves the same quick scrutiny - and their email address is the easiest place to start. The goal isn't suspicion; it's consistency. Does the footprint behind this address match the story you're being told?
- A professional presence that fits the claim - if someone presents as a senior engineer, a developer-platform and professional-network footprint is expected.
- Consistency of name and username across services. The same handle on several platforms is reassuring; a brand-new, isolated address is worth a second look.
- Account age that matches a career, not a long-con. People who've worked in a field for a decade tend to leave a decade of breadcrumbs.
- Linked emails and accounts that corroborate - or quietly contradict - the identity in front of you.
- Run the contact's business email through Account Finder, then any personal address they've shared.
- Compare the footprint with their stated role and history. Note matches and gaps.
- Follow public profile links to confirm names, photos, and bios line up.
- If something doesn't fit, raise it directly before money or commitments change hands.
A sparse footprint isn't automatically a red flag - privacy-conscious people exist, and a fresh business email may simply be new. But a senior professional with no professional footprint at all is a mismatch worth a polite question. Absence of evidence and a contradiction are different things; weigh them differently.
No. This is a fast consistency check on a digital footprint, not a formal background or credit check, and it must not be used for employment, tenant, or credit decisions. For a deeper look, the full report adds profile details and the accounts found through linked usernames, emails and phones.
Diligence isn't about catching liars; it's about confirming honest people are who they say. Most checks end with quiet reassurance - which is the point.
Account Finder groups every match by service category - social, professional, developer, gaming, shopping, messaging, and more - and attaches whatever profile details each service exposes: full name, username, avatars, bio, linked emails and phones, user IDs, account-creation date, and last-login date. A match means an account exists for that email on that service. On its own it does not tell you how actively that account is used.
- Categories show the shape of an online footprint - the kinds of services an email is registered on.
- Per-service fields (usernames, display names, bios, creation and last-login dates) help you confirm the match is the person you actually care about.
- Treat an old, dormant account differently from one with a recent last-login. Existence is a lead; recent activity is a signal.
Account Finder indexes publicly observable account metadata - the same kind of information you could assemble by hand with enough patience and the right searches. It never shows passwords, private messages, or anything hidden behind a login; the paid full report can also list known data breaches the email appears in. Use it for authorized work: OSINT, fraud investigation, due diligence, or auditing your own footprint and accounts you have permission to investigate. Do not use it for harassment, doxxing, stalking, or unauthorized surveillance. For a deeper look, the full report adds profile details and the accounts found through linked usernames, emails and phones.
