If there's one principle that consistently appears in successful fundraising stories, it's this:
Founders raise money through relationships.
That doesn't mean you need to know investors personally before launching your company. It means the strongest fundraising conversations usually begin long before the founder starts asking for capital.
Building relationships early gives investors an opportunity to watch your execution over time. They see product launches, customer growth, hiring decisions, and milestones instead of hearing about them for the first time during a pitch.
The following five channels are among the best ways to build those relationships.
1. Warm introductions from other founders
Warm introductions remain one of the most effective ways to meet investors.
When another founder introduces you, they're effectively lending part of their reputation to your company. Investors know that experienced founders rarely recommend startups they don't genuinely believe deserve attention.
Portfolio founders are often especially valuable because they already understand how a particular investor thinks and what types of businesses they fund.
Before asking for an introduction, make sure the investor is actually relevant.
Check whether they:
invest at your stage;
fund SaaS companies;
typically write checks of the size you're raising;
invest in your geography;
don't already back a direct competitor.
Making the introduction easy is equally important. Instead of asking someone to "tell them about my startup," prepare a short summary they can forward in less than a minute.
2. Founder communities
Founder communities are often underestimated as fundraising channels.
Most communities aren't filled with investors. They're filled with founders who already know investors.
That's an important distinction.
Experienced founders regularly introduce companies to angels and VC firms, recommend investors who were helpful during their own fundraising, and warn others about investors who weren't a good fit.
Communities also provide something equally valuable: fundraising feedback.
Before meeting investors, founders can receive input on:
pitch decks;
fundraising strategy;
SaaS metrics;
pricing;
positioning;
investor lists.
Over time, these conversations naturally lead to introductions.
Instead of joining communities only when you're raising capital, become an active participant early. Helping other founders creates relationships that often become valuable months later.
3. LinkedIn
LinkedIn has become one of the best platforms for building relationships with investors before fundraising begins.
Rather than thinking of LinkedIn as a place to send fundraising messages, think of it as a place to become visible.
Many investors regularly publish about the industries they're interested in, comment on market trends, and share recent investments. Following these conversations helps founders identify investors whose interests genuinely align with their companies.
LinkedIn is also one of the easiest ways to research investors before reaching out.
For example, you can review:
recent investments;
portfolio companies;
posts and comments;
mutual connections;
speaking engagements;
areas of expertise.
Instead of sending the same message to every investor, tailor your outreach around their investment thesis.
4. Existing customers
Customers can become much more than paying users.
Some become angel investors.
Others introduce founders to investors in their own network.
Even when neither happens, satisfied customers provide something investors value tremendously: validation.
Reference calls with real customers often become an important part of due diligence because they demonstrate that the product solves a meaningful business problem.
Strategic customers may also introduce founders to executives, operators, or angel investors with deep industry expertise.
5. Advisors and mentors
The right advisor can shorten months of fundraising into a handful of well-targeted introductions.
Because advisors already understand your business, they can identify investors who genuinely fit your company instead of introducing you to everyone in their network. They can also review your pitch, challenge your assumptions, prepare you for difficult investor questions, and help evaluate term sheets once offers begin arriving.
Specific requests almost always produce better results than general ones. Instead of asking whether an advisor knows any investors, explain exactly what you're looking for. A request such as "Do you know anyone investing in B2B SaaS companies raising $1 million seed rounds?" is much easier to answer and often leads to significantly better introductions.
