Investigations into the people closest to you, partners, prospective spouses, individuals targeting you online, and those threatening your safety. Quiet, documented, and built for moments where the cost of being wrong is unacceptable.
Greyline's Relationship & Personal Intelligence service line is built for moments where the cost of being wrong about someone is unacceptable — before marriage, before relocation, before sending money abroad, before introducing a new partner to your children. We investigate quietly, document properly, and give you the structured answers needed to make a decision you can stand behind.
A focused investigation into a single individual you have met online or who has approached you online — designed to determine whether the person you are speaking to is who they claim to be, and whether the relationship pattern matches known romance fraud typologies. We verify identity claims, examine the digital footprint, look for the signatures of catfishing and synthetic personas, and produce a structured findings report you can act on.
A comprehensive sweep and analytical breakdown of a named subject's online presence, social media, dating platforms, posted images, public mentions, forum activity, and the wider digital trace. The deliverable is a scored report, not a screenshot dump: we map the footprint, assess consistency against the story you've been told, and rate the risk indicators across category dimensions.
The most comprehensive pre-commitment investigation we offer — built for the moment before a major life decision: marriage, cohabitation, joint property purchase, business partnership with a romantic partner, or relocation. Combines everything in the digital footprint analysis with identity cross-checks against public records, employment and education verification, marital status indicators, link analysis of associates, and a face-to-face debrief.
Sustained intelligence on a named subject over time, delivered as a monthly briefing rather than a one-off report. We monitor weekly for new accounts, alias appearances, dating platform activity, behavioural changes, and material developments in the subject's digital life. Findings are compiled into a monthly intelligence digest and supplemented with priority alerts for confirmed material changes.
Where digital evidence is insufficient and the matter requires real-world verification, we deploy field investigators to confirm what online sources can only suggest. Discreet observation, lifestyle verification, residence and workplace confirmation, third-party identification, and physical evidence collection — all conducted lawfully under UK and target-jurisdiction law, documented with timestamped evidence, and reported to evidential standard.
Investigation into stalking, harassment, sextortion, and online intimidation, combining digital trace work to identify the source, evidence preservation to UK police-acceptable standards, takedown coordination with platforms and hosts, and structured documentation suitable for restraining order and criminal complaint applications. Where threats originate from anonymous or pseudonymous accounts, we prioritise attribution.
All inquiries are reviewed by an analyst, not a salesperson. Provide a high-level summary, no sensitive material at this stage. A confidentiality agreement is provided before any detailed disclosure.
