B2B SaaS Companies List: 154 US Software Companies by Category (2026)

How this B2B SaaS companies list was built

Every company on this page comes out of one search, run on 10 November 2026 with Find companies by tech stack: site type SaaS, country United States, mode Reliable, no technology filter, 200 results, 200 credits. Nothing was added from memory or from another directory.

The search proves a site is a SaaS, not that it sells to businesses. It reads each homepage live and gives it a type score between 0 and 1; Reliable mode keeps sites at 0.8 or more, and 191 of the 200 rows scored 0.99 (the lowest, 0.88). It returns five columns: domain, site type, type score, main country and the technologies detected on the homepage. No company name, no headcount, no industry: those come from company enrichment or from an industry lookup later. So the B2B part was done by hand: well-known consumer brands and data vendors were set aside on sight, and every other homepage was read (plus a product or about page when it was vague) to answer two questions: what does the company sell, and to whom.

How to read what follows. The 100 companies with a description are the first 100 B2B companies in the order the search returned them; the 54 that came later sit in one table further down. The category is an editorial call from the company's own site, in a closed list of nine, one category per company. Inside a category, rows follow the type score, then the alphabet. The headquarters column shows a city only when the company's site displays it, otherwise the country the search returned. Descriptions were written from each company's pages, read on 10 November 2026; the domain stays the stable key if a company rebrands.

The free CSV on this page holds 100 raw rows of the same search, in the order returned, with the technologies detected. Companies that sell contact data, scraping or prospecting tools are left out, and so are sales data and intent data tools in the technologies column. It is the output before the B2B read: 84 of its rows are described below, 10 are consumer or double-audience products and 6 could not be read. Company data only, no emails and no phone numbers. All the company data guides of this series are on the business data hub.

The well-known names in this run

Ten companies in this run are names most B2B buyers already know, and they make a useful benchmark for the rest of the list: if your offer fits them, it probably fits the smaller companies sitting next to them in the same category.

None of them was picked by size. They are here because the search returned them, which is also why some famous SaaS names are absent: one run of 200 is a sample of the US market, not a census. Canva, for instance, came back in the run but its site refused automated reading, so it was left out rather than described from memory.

More B2B SaaS companies from the same run

These 54 companies passed the same B2B read as the 100 above. They came later in the order the search returned, so they get a single row here, sorted by category then type score. The list is not cut alphabetically: it is cut by search order. If one of them fits your offer better than anything above, its domain is where the next step starts.

What these companies run on their websites

The fifth column of the search, technologies, is the one most lists skip, and for a seller it is often the most useful. Across the 154 B2B SaaS companies kept from this run, here is how often a few tools appear in what their homepage loads:

Three readings are worth keeping. First, the LinkedIn Insight Tag on 79% of them says these companies advertise or retarget on LinkedIn, which tells you where their marketing team spends attention. Second, 29 of the 57 sites that load Salesforce also load HubSpot, often one for marketing forms and the other for the sales pipeline, so "uses HubSpot" does not always mean "HubSpot is their CRM". Third, a script on a homepage proves the tool is loaded on the site, not how deeply it is used inside the company. Treat the column as a strong reason to look closer, not as a contract you can quote. For more on what a stack fingerprint can and cannot tell you, see our guide to technographic data.

How to build a B2B SaaS companies list for another country or stack

The method above is reproducible, and that is the point of showing it. The tutorial below runs the same search in the Derrick web app, with Stripe added as a technology.

Three settings change the result:

• Country. Swap United States for any two letter country code. The French version of this page used the same search with France and returned 200 French SaaS sites. A site type alone is enough: you do not need to name any technology to list every SaaS in a country.
• Technology. Add one or more tools to narrow the list to companies that run them. SaaS plus Stripe gives software companies that bill through Stripe, which is a good starting list if you sell anything around billing, revenue or finance. A site must run every technology you add, so two tools narrow faster than one.
• Reliability and size. Reliable keeps sites with a type score of 0.8 or more. Broad returns more rows with a few mistakes, useful when the segment is rare. You can also leave out the biggest sites (the top 1,000, 10,000, 100,000 or 1,000,000) to focus on smaller companies.

Because each homepage is read live, a single call returns up to 500 companies and stops by itself when matches become rare. In that case, add a country or a technology, or switch to Broad. Then do what this page did: read the sites, keep the ones that sell to businesses, and drop the rest. The search gives you the SaaS; the B2B judgment stays yours, and it is the part that makes the list worth contacting.

If you start from domains you already hold rather than from a search, the reverse step exists too: Website Technologies reads the stack of a given site at 2 credits per website. Do not mix the two up: one finds companies, the other describes a company you already have.

How to tell if a website is a SaaS, and if it sells B2B

The type score settles the first question at scale. For the second, reading the site is still the fastest method, and a few signs come back on almost every homepage that sells to businesses:

• a "Book a demo" or "Talk to sales" button next to, or instead of, "Sign up";
• pricing per seat, per user or per team, often with a plan labelled Enterprise and no public price;
• words like "your team", "your customers", "workflow", "integrations", "SSO" or "SOC 2" in the first screen;
• a customer section that shows company logos rather than individual reviews.

The opposite signs point to a consumer product: an app store badge as the main call to action, a monthly price for one person, and language about "you" rather than "your team". The hard cases are the double-audience products, which this page removed: a website builder used by both solo creators and agencies, a podcast tool used by hobbyists and brands. Whether to keep them depends on what you sell. If your offer only makes sense for a company with a sales or support team, removing them saves you a lot of wasted outreach.

The same read also gives you the category and what the company does, which is how each description above was written. If you need that at scale, our guide on getting a company description from its website shows how to fill it row by row, and the one on finding a company's industry covers the classification side.

Selling to B2B SaaS companies: from a list to a conversation

A list of domains is the start of the work, not the end. Three steps turn it into accounts you can actually approach, and Derrick runs each of them from the same rows:

1. Check who is hiring. Company Hiring Signal costs 1 credit per company and returns whether it is hiring, how many open roles it shows (up to "10+") and the job titles. A SaaS hiring account executives has budget and a sales problem. A SaaS hiring support agents is growing its customer base. The titles tell you which door to knock on.
2. Get the company profile. Enrich Companies costs 1 credit per company and adds the firmographics the search does not return, such as headcount and industry. It works from the company's LinkedIn page and needs your LinkedIn account connected to Derrick. Both this step and the hiring signal take a LinkedIn company URL as input. The search gives you domains, and the description pass gives you names: Search Companies then finds the LinkedIn company URL from the name, at 1 credit per company, with your LinkedIn account connected.
3. Find the people. Import Leads from Target Companies lists the employees of the companies you choose, filtered by job title, at 1 credit per lead. It runs on your own LinkedIn session and starts from a Sales Navigator search, so it needs your LinkedIn account connected and Sales Navigator. In a SaaS company the buyer is rarely the founder once the team passes a few dozen people: look for the head of the function your product serves (RevOps for sales tools, the CFO or finance lead for billing, the CTO or platform lead for developer tools).

Two questions come up every time someone sells to software companies. When should you reach out? The honest answer is when something has changed: a new role posted, a new market announced, a new product line on the site. The hiring signal catches the first one; the others come from reading the site, which this list already did once. Who chooses the vendors? In a SaaS company, the person who owns the budget for the problem, usually a function head, with the founder involved on bigger or strategic purchases. Neither question has a universal number, and you should be wary of anyone who gives you one.

What a B2B SaaS companies list costs to build in Derrick

The list on this page took one search and a read of every homepage it returned. In credits:

Find companies by tech stack runs on paid plans, from STANDARD at 20 euros a month with 10,000 credits, in the web app and the Google Sheets sidebar. From Claude over MCP or through the REST API, it needs PLUS (47.50 euros a month, 25,000 credits) or above. The hiring signal, Search Companies and company enrichment also run on the free plan, whose 100 credits a month are enough to test them on a handful of the companies above before you commit.
