What Is a B2B Investor?
A B2B investor backs startups that sell to other businesses instead of to consumers. That could be a software tool a finance team pays for, a logistics platform a retailer runs on, or a security product a hospital buys.
Here's the thing to know before you start: B2B isn't an industry. It's a way of making money, which is why it cuts across almost every other category in the database. Close to half of all investors in Angel Match carry the B2B tag, so filtering by B2B alone won't give you a list you can actually use. You need a second filter, like your stage, your location or the market you sell into.
There's a lot of overlap between this list and the SaaS and enterprise software lists, since plenty of B2B startups sell software. But B2B also covers hardware, services, marketplaces and financial infrastructure. If your product isn't software, this page is the better place to start. If it is software, start with the narrower list and come back here to widen your search.
What B2B Investors Look For
B2B investors care less about how fast you're growing and more about how hard it is for your customers to leave. That one idea explains most of the questions you'll get.
Start with who signs the contract and how long it takes. Investors want to know the job title of the person who says yes, how many people have to approve the purchase, and how many months pass between the first call and the first payment. Put the answer in the first two lines of your email. A long sales cycle isn't a dealbreaker. Not knowing your own sales cycle is.
Next comes retention. A customer who pays once and leaves is a bad result in B2B, because winning that customer took real selling time. Investors look at how many customers renew, whether customers spend more over time, and whether contracts run monthly or annually. If you're too early for real renewal data, show the next best thing, like a customer who grew from one team to three, or a pilot that turned into a paid contract. Sales-led companies spend a lot up front to win each account, so work out your payback period with a CAC calculator before you talk numbers with anyone.
Then there's concentration. If one customer makes up most of your revenue, expect questions. It's common in early B2B, so don't hide it. Say how big a share that customer is, how long the contract runs, and what you're doing to land a second and third anchor customer.
Be careful with pilots, too. A free pilot tells an investor very little, and a letter of intent isn't revenue. A paid pilot with a clear path to a full contract is worth far more, even at a small price. If all you have is free pilots, explain what would have to be true for each one to convert.
Finally, look at how you win customers. At seed, B2B investors usually expect the founders to still be doing the selling, and they'd rather see you learn what works than hire a sales team too early. By Series A, they want a sales process that someone other than you could run. Know which of those two you are and be honest about it.
What Stages B2B Investors Back
Seed is where the most B2B investors sit. Nearly a third of the list, 17,000+ investors, backs seed rounds. Early stage venture is next at 14,000+, then pre-seed at 5,000+ and Series A at 4,000+. Series B comes in at 2,500+ and late stage venture at 1,000+. Investors often back more than one stage, so don't add those numbers together.
The pattern to notice is how fast the list thins out. For every Series B investor, there are roughly six who back seed. That's good news if you're early, because you have plenty of choices. It's a warning if you're planning ahead, because the pool you'll pitch in two or three years is much smaller, and those investors will expect a repeatable sales process, not just early wins.
Long sales cycles make timing trickier for B2B than for most startups. Revenue shows up months after the work starts, while costs don't wait. When you decide how much to raise, plan for a slow close, not a fast one, and check what that does to your runway. A round that looks big enough on paper can run short if your first three big deals each take an extra quarter.
Who Invests in B2B Startups
Two groups dominate the list. There are 33,000+ venture capitalists and 32,000+ angel investors, and each group is more than half of the total, which tells you they overlap a lot. One person often carries more than one label, so don't add them together. Another 32,000+ are tagged as private equity investors.
If you're at pre-seed, lean on angel investors. Angel checks usually run $25,000 to $500,000, angels can decide without a committee, and the best ones for B2B have run sales teams or bought software at real companies. Ask them for introductions to buyers, not just money. One intro to the right head of finance can be worth more than the check.
Venture capitalists write bigger checks, from $2 million to $100 million or more, and they want a clear story about how the business gets large. Your best case is a customer list that's growing and getting stickier, plus a reason the next customer will be easier to win than the last. Micro VCs, which number 2,000+ on this list, sit in between. They tend to write smaller checks than larger funds and often move faster, which suits a first B2B round.
Where B2B Investors Are Based
More than half of the B2B investors on this list are in the United States. The United Kingdom is a distant second, and India comes third, ahead of Germany, France and Canada. If your first customers are in India, that's a sizable local pool worth filtering for.
In the city rankings, New York City is the most common investor location, slightly ahead of San Francisco. London is third and Boston is fourth. That's a small gap, but it matters if you're deciding where to spend your first round of meetings. One possible reason is that business buyers cluster in places like New York and London, and investors who want to be near those buyers go where they are. If you sell to banks, insurers, agencies or big retailers, a New York list probably deserves more of your time than a default Bay Area one.
By state, California is the biggest pool, but its investors are spread across the Bay Area, Los Angeles and beyond. New York's are almost all in the city itself, so one trip can cover a lot of ground.
How to Build Your B2B Investor List
Start with the customer, not the investor. Pick the market you sell into and add it on top of the B2B filter. If you sell payments software to small businesses, pair B2B with fintech. If you sell scheduling tools to clinics, pair it with health care. Investors who've backed companies in your buyer's world usually understand the sales process, which saves you a lot of explaining.
Next, add your stage and then your location. Be honest about your stage. If you have a prototype and two pilots, you're usually pre-seed in an investor's eyes, however you describe it.
Before you send anything, open each investor's portfolio and look for two things. The first is customers: has this investor backed a company that sells to the same kind of buyer as you? If so, they may be able to make introductions. The second is competitors. Many B2B investors avoid funding two companies that fight over the same customers, so a direct competitor in their portfolio usually means a polite no. Cross those names off early and spend your time on investors who have an obvious reason to say yes.
