Find SaaS companies and software company decision makers

These are not hidden. Software companies are the archetype every contact database was built around, so the list is the easy part. What no database field carries is which marketplaces a product is listed in, whether the SOC 2 Type II is current, what the product actually does past the category label, and who it sells to. Search on those, and Causo reads AWS Marketplace and AppExchange listings, trust centres, public changelogs, GitHub and filings at Companies House and SEC EDGAR company by company, then shows you the evidence behind every match.

Ask anything about a SaaS company

Every result is a starting point, not an endpoint. Ask a follow-up about any company on your list in plain English and the agents go back out and read for it, then answer with the sources they used.

Which platforms do they actually integrate with?
Answer

Two listed marketplace apps, Salesforce and HubSpot, plus a documented public REST API. Nothing listed on the Shopify App Store.

SourcesMarketplace listings + the vendor’s docs site
Do they hold SOC 2 Type II, and when was it issued?
Answer

Yes. A SOC 2 Type II report covering a twelve month window ending in March, and ISO 27001 is listed as in progress rather than certified.

SourcesTrust centre + the vendor’s security page
What do they run on, and who do they actually sell to?
Answer

AWS in two regions with Postgres underneath, and the published case studies are all mid-market lenders and insurers rather than consumer apps.

Contact databases are assembled from what companies publish about themselves: professional profiles, funding rounds, tech stacks, hiring pages. A software company produces every one of those by default. It is the archetype those databases were built around, so pulling a list of tens of thousands of SaaS companies in a given headcount band takes about a minute, and anyone can do it. Finding them is free. Qualifying them is the entire job, and that is exactly where the fields run out. No contact database records whether a product is genuinely listed in AWS Marketplace, the Salesforce AppExchange, the HubSpot App Marketplace or the Shopify App Store, or what that listing says it does. None carries whether a vendor holds SOC 2 Type II or ISO/IEC 27001, what the report covers, or the date it was issued. None holds which cloud the product runs on, which database sits underneath it or whose payments it takes, all of which are readable from a status page, a docs site and a public changelog. None separates who a company sells to from what it is, so a vendor whose customers are all mid-market lenders sits under the same label as one selling to dental practices. And none notices that a first head of platform engineering role was created six weeks ago. That evidence lives in marketplace and app directory listings, trust centres and attestation summaries, status pages, changelogs and docs, job postings, GitHub, and filings at Companies House and SEC EDGAR. The record you get back says "computer software, 80 employees, Austin" and stops precisely where your qualification starts.

Frequently asked questions.

Because integrations are not a field in a contact database. Apollo and ZoomInfo cover software companies better than any other segment, since their collection method is built on professional profiles, funding rounds, tech-stack detection and hiring pages, all of which a SaaS company produces by default. What they hold is firmographic: headcount, location, an industry label. Whether a product is listed in AWS Marketplace, the Salesforce AppExchange, the HubSpot App Marketplace or the Shopify App Store is published in those marketplaces instead, and no filter reaches into them.

Read the marketplace itself rather than a contact database. AWS Marketplace, the Salesforce AppExchange, the HubSpot App Marketplace and the Shopify App Store each publish the vendor, what the app does, which editions it supports and when the listing appeared. Causo reads those directories alongside each vendor’s own integrations and docs pages, so being listed on a given platform becomes something you can search for directly instead of inferring it from a company description.

From the assurance evidence, not from a database field. SOC 2 Type II reports are issued by CPA firms under AICPA standards and are not held in a public register, so vendors publish the status themselves on a trust centre or security page, usually with the report type, the period it covers and the date it was issued. ISO/IEC 27001 certificates are issued by accredited certification bodies, in the UK by UKAS accredited bodies, and those bodies publish client registers. Causo reads trust centres, security pages and certification body registers, so certification type and issue date become searchable.

By reading the product rather than the label. Two companies filed under "computer software" can be a competitor and a perfect partner, and the industry code will not tell them apart. The distinction shows up in the docs site, the public changelog, the pricing page, the API reference and the customer case studies. Causo reads those and reports what the product does at the level of detail you need to decide whether it is a fit, a competitor or neither.

Yes, in plain English. A company’s own ICP is not a field in any contact database, which records what a company is and not who its customers are. It is readable from published case studies, customer logo walls, the verticals named on the pricing and solutions pages, the compliance claims the product makes, and the segment its G2 and Capterra reviewers sit in. Causo reads those and reports the buyer vertical alongside the company.

The company, why it matched, the evidence behind that with its source, and the decision maker with a verified email address. For a software company that typically means which marketplaces the product is listed in, what it genuinely does past the category label, which certification it holds and when it was issued, the cloud and database it runs on, the vertical it sells into, its funding stage, and any newly created engineering or compliance role. You can then ask follow-up questions about any result and get answers with sources attached.

Yes, and software is one of the few genuinely global markets. Marketplace and app directories such as AWS Marketplace, the Salesforce AppExchange, the HubSpot App Marketplace and the Shopify App Store are worldwide, as are trust centres, GitHub and status pages. The filing layer differs by country: in the United States it is SEC EDGAR and the state business registries, in the United Kingdom Companies House, in Germany the Handelsregister, in the Netherlands the KVK, in Ireland the CRO and in Australia ASIC. Causo reads whichever set applies to the country you are searching.
