Use cases
Find managed service providers and MSP decision makers
They are already in the databases. What is not in any database is which vendor designations they hold, which verticals they really serve, whether they sell managed services or break/fix, and who owns them now. Search on those, and Causo reads the Microsoft Solutions Partner directory, the IASME Cyber Essentials certificate search, G-Cloud listings and Companies House provider by provider, then shows you the evidence behind every match.

Ask anything about an MSP or IT services provider
Every result is a starting point, not an endpoint. Ask a follow-up about any provider on your list in plain English and the agents go back out and read for it, then answer with the sources they used.
Which vendor designations do they actually hold?
AnswerSolutions Partner for Security and for Modern Work, plus an advanced specialisation in Threat Protection. Nothing on the Azure infrastructure side.
SourcesVendor partner directory + the provider’s own partner page
Is their Cyber Essentials Plus certificate still in date?
AnswerYes. Certified in March and valid for twelve months, and the certificate is held by the trading company rather than the group parent.
SourcesIASME certificate search + the provider’s trust page
Are they still independently owned?
AnswerNo. A private equity backed platform took a majority stake in April, and two other providers were added to the same group in the same quarter.

Contact databases are assembled from what companies publish about themselves: professional profiles, funding rounds, tech stacks, hiring pages. An IT services firm produces all of that by default, so unlike a fabricator or a care home it is already in Apollo and ZoomInfo, with a headcount, a location and an industry label. The company is in the database. The thing you need to filter on is not. No contact database carries which Microsoft Solutions Partner designations a provider holds, whether its Cyber Essentials Plus certificate is still in date, whether it is a registered C3PAO or merely says it is CMMC ready, whether it delivers managed services or break/fix or is really a reseller with a support contract stapled on, which verticals its client list actually sits in, which partner tier it reached this year, or whether a private equity platform bought it last quarter. Those facts live in vendor partner directories, the IASME certificate search, UKAS accredited certification bodies, the Cyber AB marketplace, G-Cloud supplier listings, Companies House and the providers’ own technical pages. None of those are where a profile-derived database looks, so the record you get back says "IT services, 45 employees, Dallas" and stops exactly where your qualification starts.

Apollo vs ZoomInfo vs Causo for MSP leads
| Apollo / ZoomInfo | Buying a list | Causo | |
|---|---|---|---|
| Filtering on "Solutions Partner for Security" | No such field | No such field | Read from the vendor partner directory |
| Telling managed services apart from break/fix and pure resale | Both sit under "IT services" | Not distinguished | Read from service, contract and pricing pages |
| Cyber Essentials Plus, ISO 27001, SOC 2 or CMMC status, and its date | Not tracked | Date the list was compiled | Read from the certification register at search time |
| Which providers a private equity platform already owns | Parent field is often stale | Rarely mapped | Read from registry filings and deal announcements |

Frequently asked questions.
Because those are not fields in a contact database. Apollo and ZoomInfo cover IT services firms well, since the collection method is built on professional profiles, web signals and hiring pages, all of which an MSP produces. What they hold is firmographic: headcount, location, industry label. Vendor designations, partner tier, certification level and the date it was awarded, delivery model and vertical concentration are published elsewhere, in partner directories, certification registers and company filings, and no filter can reach them.
Read the partner directory rather than a contact database. Microsoft publishes Solutions Partner designations across six solution areas, including Security, Modern Work and Infrastructure, along with advanced specialisations, and AWS and Cisco publish equivalent partner tiers in their own finders. Causo reads those directories alongside each provider’s own partner page, so you can search for a designation directly instead of guessing from a company description.
By reading what the firm sells rather than how it is labelled. All three sit under the same industry code in a contact database. The distinction shows up in contract language, whether pricing is per seat or per hour, whether there is a service desk and a NOC, whether staffing ads are for recurring support roles, and whether the vendor relationship is a resale agreement or a managed offering. Causo reads those pages and job posts and reports which of the three a provider actually is.
Start from the certification body, not the vendor. In the UK, IASME administers Cyber Essentials and Cyber Essentials Plus on behalf of the NCSC and publishes a certificate search, and ISO 27001 certificates are issued by UKAS accredited certification bodies that publish their client registers. In the United States, SOC 2 attestations are issued by CPA firms and providers publish the report status themselves, while CMMC readiness and C3PAO registration sit on the Cyber AB Marketplace. Causo reads those registers and pages, so certification level and award date become searchable.
Yes, from filings rather than from a parent-company field. In the UK a change of control shows up in Companies House as a new person with significant control and in the confirmation statement, in Ireland it appears in CRO filings, in the Netherlands in the KVK register, and in the United States in state registry amendments and, for listed acquirers, SEC filings. Causo reads those alongside deal announcements, so a provider bought last quarter is separated from one that is still founder owned.
The provider, why it matched, the evidence behind that with its source, and the decision maker with a verified email address. For an MSP that typically means the vendor designations it holds, its certification level and the date it was awarded, whether it delivers managed services or resells, the verticals its clients sit in, and its current ownership. You can then ask follow-up questions about any result and get answers with sources attached.
Yes. Vendor partner directories such as the Microsoft Solutions Partner directory, AWS Partner Finder and Cisco Partner Locator are global. The local layer differs: in the United States it is the Cyber AB Marketplace, the FedRAMP Marketplace, SAM.gov and state business registries; in the United Kingdom it is the IASME Cyber Essentials certificate search, G-Cloud on the Digital Marketplace and Companies House; in Ireland it is the CRO, in Germany the Handelsregister and in the Netherlands the KVK; in Australia it is ASIC and the ACSC partner programme. Causo reads whichever set applies to the country you are searching.
