How to Find Investors for a Startup: A Founder's Playbook for Targeted Outreach
Updated: Sep 19
Founders think fundraising is a numbers game. Email 400 investors, book 12 meetings, close 2 checks. It is not a numbers game. It is a targeting game.
The founder who emails 60 well-researched investors gets more meetings than the founder who emails 400 cold. Not slightly more. Meaningfully more. Warm and researched outreach converts at ten to thirty times the rate of cold, generic outreach. The math on hours per meeting, on quality of conversation, and on time to close all favor the smaller list.
The founders who close their round in eight to twelve weeks share one thing: they built a list of 60 to 80 investors, they knew exactly why each name was on the list, and they reached almost every one of them warm. Founders who take nine months usually built a list of 400 and reached most of them cold.
This guide covers how to build the list, where to actually find investors that match, how to research each name before reaching out, and how to get warm intros that convert.

Why Targeting Beats Volume in Investor Outreach
Every venture investor operates inside a narrow slice. A partner at a $200M seed fund with a thesis in vertical SaaS does not write checks into consumer marketplaces. A US-based fund with a mandate to invest in Delaware C-corps does not write into UK LTDs. A $50M pre-seed fund does not lead a $10M Series A.
Founders who ignore these constraints and pitch every investor they can find are not being efficient. They are training investors to see them as unfocused. The same email sent to 400 partners across every stage, sector, and geography signals to any partner who checks that they were name 397 on a list, which lowers the odds of a reply from a partner who might otherwise have been the right fit.
The alternative is a list of 60 to 80 investors where every name has been chosen for a specific reason. The founder can articulate, for each name, why this fund invests in this stage, this sector, and this check size, and what portfolio pattern makes them a plausible lead or follow. That level of preparation produces a first email that reads specifically to the recipient, which is the entire difference in response rate.
The best fundraising lists are short and sharp. If you cannot explain in one line why each investor is on your list, they should not be on it.
The Five Filters Every Investor List Needs
Every investor on your list should pass five filters. If a name fails any one of them, they come off the list. This is not optional. A misaligned meeting takes the same hour to prepare and hold as a well-matched one, and it converts to a check almost never.
Filter 1. Stage
The most binary filter. Pre-seed funds do not lead Series A rounds. Growth funds do not write $500K checks. For each investor, confirm the stage they lead at, the stage they follow at, and the stage they no longer touch. Fund websites and Crunchbase both usually list this. If a fund is stage-agnostic in name only, check their last 20 deals to see where they actually deploy. This is especially important when your round is at a stage boundary: if you are raising a pre-seed round, most "seed" funds will not participate. If you are raising a Series A, pre-seed funds will not have enough capital to lead.
Filter 2. Sector
Not "SaaS." That is a category. Look at the fund's stated thesis and the actual pattern in the portfolio. "Vertical SaaS for regulated industries," "consumer-facing marketplaces," "dev tools and infrastructure," "deep-tech hardware." A fund that says "SaaS" but has invested in fifteen dev tools companies and one CRM in the last three years is a dev-tools fund. Match your company to what they actually fund, not what their homepage says they might.
Filter 3. Check size
A fund's typical initial check is public information and it is decisive. A $50M seed fund cutting $500K checks writes 100 deals across the fund. A $50M fund cutting $2M checks writes 25. The check size determines how many partners you compete with for attention and how much conviction the partner needs to write a check. If your round needs a $3M lead and the fund's typical initial check is $500K, they cannot lead. Move them to follower status or off the list.
Filter 4. Geography
Not just where the fund is located, but where they invest. Some US funds only invest in Delaware C-corps. Some European funds only invest in Europe-headquartered companies. Some funds actively invest in emerging markets, others actively avoid them. Check the location of the last 20 portfolio companies. If none of them look like you geographically, do not add the fund to your list.
Filter 5. Portfolio pattern
This is the filter founders skip most often. Read the last 20 investments the fund has made. Two questions: does any of them compete directly with you (in which case the fund cannot invest for portfolio conflict reasons), and does the fund have a clear pattern that supports investing in a company like yours (which raises your odds materially).
A fund whose last four investments are all AI-native infrastructure companies is telling you what their next check probably looks like. A fund with a scattered portfolio is telling you they do not have a strong thesis, which means the partner has to convince the whole partnership on the merits of your specific deal.
Where to Actually Find Investors: A Tool-by-Tool Breakdown
There is no single database that surfaces every investor who fits your five filters. Serious research uses three to five tools in combination. Below, the ones that consistently produce the highest-quality list, roughly in order of how founders should use them.
Crunchbase
The starting point for most fundraises. Free tier is limited, but Pro (paid) lets you filter funds by stage, sector, check size, geography, and recent activity, and lets you export lists. Crunchbase is the fastest way to build a first pass at the top of the funnel, before you narrow with the other tools.
PitchBook
More comprehensive than Crunchbase, with deeper deal history and detailed fund profiles. Enterprise pricing, but many law firms, accelerators, and business schools offer access to their startup members. Ask if your legal counsel or your accelerator has a seat you can use. PitchBook is especially useful for confirming a fund's exact check size, deployment pace, and remaining dry powder.
Signal.NFX
Free. Built by NFX. Its most useful feature is the ability to map your network to specific investors, showing you who you know that can make an introduction. For warm intro planning, Signal is one of the highest-value tools available at no cost.
OpenVC
Free searchable directory of venture funds with filters by stage, sector, and geography. Not as deep as Crunchbase or PitchBook, but useful for building a wide first-pass list and for finding smaller funds that may not appear prominently elsewhere.
AngelList / Wellfound
The right tool for angel investors and syndicates rather than institutional venture. If your round includes angel checks (as most seed and pre-seed rounds do), AngelList is where you find them. Look at syndicates that lead in your sector and stage, and at solo GPs who invest through the platform.
LinkedIn Sales Navigator
The best tool for finding the specific partner at a fund who covers your sector and stage. Filter by title, current company, and industry to identify the exact person to reach out to. Do not skip this step: emailing "info@fund.com" or a general partner who does not cover your sector rarely produces a response.
Twitter / X and podcasts
Real-time signal on what investors are thinking. Investors publicly state their thesis, share what they are excited about, and comment on their portfolio. A partner who tweets about vertical SaaS every week is a lead for your vertical SaaS company. A partner who has appeared on three podcasts about AI infrastructure is a lead for your AI infrastructure company. Read their last 20 tweets and their last two podcast appearances before you send an email.
Portfolio scraping
The single most productive research tactic. Find three to five companies that recently raised at your stage and closely resemble your business. Look at who invested in them. Those are the highest-quality candidates for your list because they have already made the exact bet you are asking them to make again.
The best investor list is not built from one tool. It is built by cross-referencing three or four. Crunchbase for breadth, Signal for warm-intro mapping, LinkedIn for the right partner, and portfolio scraping for the highest-signal candidates.
How to Research an Individual Investor Before Reaching Out
Before adding a name to your list, and before sending the first email, do 15 to 30 minutes of research on each investor. What to look for:
Fund thesis. Read the fund's homepage and thesis pages. What do they say they invest in, and what is the language they use to describe it? If your outreach uses similar language back to them, response rates rise materially.
Last 20 investments. Look at the fund's recent portfolio on Crunchbase or PitchBook. What stages, sectors, and check sizes have they actually deployed into? What patterns emerge?
Partner-specific coverage. Funds have partners who specialize. Identify the partner most likely to lead your deal, not a random name at the top of the website. Look at what deals they have personally led (not just the fund's) and what they have written or spoken about publicly.
Recent public statements. Twitter, LinkedIn, podcast appearances, and blog posts from the last 90 days. A partner who has just written about the AI moat problem is receptive to a pitch that leads with your answer to it.
Portfolio conflicts. Check the fund's portfolio for direct competitors. Do not pitch a fund that has recently invested in a company you compete with. They cannot invest, and a poorly researched approach loses you their attention permanently.
Path to introduction. For each name on your final list, identify the highest-quality path to a warm intro before you send anything cold. Signal.NFX and LinkedIn are the fastest tools here.
Building a Tiered Investor Outreach List
A final outreach list should be organized into three tiers. The tiers determine the order of outreach, the level of preparation, and how much runway you use on each name. The math on how much warm intro capital and prep time you have does not support treating every investor identically.
Tier 1 (10 to 15 investors)
Perfect fit on all five filters, plus a warm intro path. These are the investors most likely to lead your round. Hold Tier 1 until you have built early momentum (usually week 2 or 3 of your raise), then approach them with social proof from Tier 2 conversations. Reaching Tier 1 first, before you have momentum, wastes the strongest names in your network.
Tier 2 (30 to 40 investors)
Strong fit, plausible thesis match, warm intro available or best cold approach option. This is the core of your outreach and where most first meetings will come from. Start here in week 1 of your raise. Tier 2 is also where you generate the momentum signal that Tier 1 will respond to.
Tier 3 (20 to 30 investors)
Decent fit, worth a meeting if scheduled, but not where you focus. Use Tier 3 for pitch practice in the first week. First meetings with Tier 3 sharpen your delivery before you spend it on Tier 2 and Tier 1. Some Tier 3 conversations will surprise you and produce a check, but do not plan on it.
How to Get Warm Introductions That Actually Work
A warm intro to a partner from someone the partner trusts is the single highest-conversion outreach method in venture. The gap between warm and cold response rates is large enough that founders should treat warm intro sourcing as its own workstream.
The best sources of warm intros, in rough order of quality:
Founders in the fund's portfolio. A founder who is already funded by the partner and who says "you should take this meeting" is the highest-signal intro possible. Find the portfolio company most similar to yours, find their founder on LinkedIn, and send them a short, specific message.
Your existing angels or seed investors. If you have raised any prior capital, your existing investors have an economic interest in your next round closing. They should be introducing you actively. If they are not, ask directly and give them a short forwardable email to send.
Other investors you have met. Investors who have passed can still be a source of intros. When a partner passes, ask if there are one or two funds in their network they would recommend you speak with. Most will give you at least one name.
Accelerator and program networks. Y Combinator, Techstars, On Deck, EF, and industry-specific accelerators all provide access to a preferred list of partner funds. If you have been through one of these programs, use the intros. If you have not, the demo-day funds are still identifiable and reachable.
LinkedIn second-degree connections. Signal.NFX and LinkedIn Sales Navigator both surface 2nd-degree paths to specific partners. Not every 2nd-degree connection is willing to make an intro, but some are, and the ask costs almost nothing.
Founder friends who recently raised. Founders who closed a round in the last 6-12 months know which partners were sharp, which were slow, and who is actually deploying. They will intro to their favorites if you ask directly.
For every intro request, write a short forwardable email that the introducer can send with one or two lines of their own. Make it easy. An intro request that requires the introducer to write the email themselves will not be sent.
Five Mistakes That Kill Investor Outreach
Mistake 1. Spraying without targeting
Sending the same email to 400 investors across every stage and sector. Response rates on this approach are consistently in the low single digits, most of the meetings that come out of it do not match, and the founder burns four to six weeks of a nine-week raise on misaligned conversations. The founder who instead spends the same time building a list of 60 to 80 highly-targeted names outperforms on every measurable metric.
Mistake 2. Pitching the wrong stage
Approaching a growth fund at pre-seed, or a pre-seed fund at Series A. Both are common. Both waste weeks. Every fund publishes their stage focus. If a fund's typical initial check does not match the round you are raising, take them off the list. Do not spend your energy trying to convince a growth fund to write their smallest check ever.
Mistake 3. Ignoring the associate
Most first meetings at institutional venture funds are with associates, not partners. Some founders treat associates dismissively or push to skip them. Associates are the primary screen at most funds. A good associate advocate is one of the strongest positive signals a partner will encounter about your company internally. Take the associate meeting seriously and treat it as the real meeting it is.
Mistake 4. Pitching a portfolio conflict
Reaching out to a fund that has recently backed a direct competitor. This is a two-minute check that founders often skip. When a fund has already made the bet you are asking them to make, they cannot invest, and the poorly-researched approach costs you their attention on the next company you build.
Mistake 5. Using a generic email
The email opens with your company name and a boilerplate description that could have been sent to any fund. Investors read hundreds of these every week and skip them by default. The fix is a single, specific sentence at the top that references something the partner has said, written, or invested in recently. That one sentence changes the response rate more than any other single variable.
How Investor Research Connects to the Rest of Your Raise
Investor targeting sits upstream of every other fundraising activity. A great pitch deck sent to the wrong investors converts poorly. A weak pitch deck sent to the right investors also converts poorly. The strongest raises stack both variables: a problem and solution that land clearly, traction that meets the stage bar, unit economics that hold up in diligence, and a list of investors who are pre-qualified to say yes to a company that looks like yours.
For sector-specific fundraising, the targeting rules tighten. SaaS founders have more funds to choose from and can afford a wider first pass. AI startups have a small number of AI-native funds that dominate the category, and hitting them warm is disproportionately important. Fintech founders face a specialist audience that filters heavily by regulatory posture and geography.
When Founders Should Get Help Finding Investors
A few signals that investor targeting is holding back the round:
You are 400 emails in and have booked fewer than 15 meetings.
The meetings you have booked are largely with investors who do not match your stage or sector.
You have never seen your fund shortlist verified by someone who has watched a real raise close.
You have no idea who the right partner at each fund is, or how to get a warm intro.
At RunwayTeam, our tailored investor outreach work builds a research-backed list of the specific investors most likely to lead your round, mapped by warm-intro path, and paired with the outreach language that has landed for similar founders. If you are still figuring out who to talk to, book a strategy call and we will tell you where your list is losing you meetings.
Frequently Asked Questions
How many investors should I contact for a fundraise?
Between 60 and 85 investors on your final outreach list, organized into three tiers. Fewer than 60 usually means you have not built enough coverage across your stage and sector. More than 85 usually means you are not researching enough per name and the list is filled with poor-fit funds who will not respond. The exact number depends on stage: pre-seed rounds usually run wider (mixing angels and micro-VCs), Series A rounds run narrower (focusing on institutional lead-capable funds).
How do I find angel investors for a startup?
AngelList and Wellfound are the most direct tools. Signal.NFX and LinkedIn are useful for identifying angels in your network who invest in your sector. Look at recently-funded startups similar to yours and check who backed them at the angel round. Founder-turned-angel networks (like operators who have exited and are now investing) are one of the highest-quality categories of angel because their advice compounds with their check.
What is the best way to find VC investors?
Cross-reference three tools. Crunchbase or PitchBook for breadth and deal history. Portfolio scraping (finding recently-funded companies like yours and looking at their investors) for the highest-signal candidates. Signal.NFX for mapping warm-intro paths. Then verify each name against your five filters (stage, sector, check size, geography, portfolio pattern) before adding them to your list.
How do I get a warm introduction to an investor?
The highest-quality path is a founder in the fund's portfolio. The next is your existing angels or seed investors. Other sources include LinkedIn 2nd-degree connections, accelerator alumni networks, and founder friends who have recently raised. For every intro request, write a short forwardable email the introducer can send with one line of their own. Making the intro one click of effort dramatically increases the odds it actually happens.
Should I cold email investors?
Warm intros convert better, but well-researched cold emails still work. A cold email that references something specific about the partner (a portfolio company, a recent tweet, a podcast appearance) and that gets to your one-line company description in the first two sentences performs meaningfully better than a generic template. Cold email should not be the first line of attack for Tier 1 names, but it is a legitimate tool for the rest of the list.
What tools should I use to research investors?
Crunchbase (Pro tier for real value), PitchBook if you can get access through a law firm or accelerator, Signal.NFX for warm-intro network mapping, OpenVC for wide first-pass filtering, AngelList for angel investors and syndicates, and LinkedIn Sales Navigator for identifying the right partner at each fund. Then augment with the partner's Twitter, podcast appearances, and blog posts to understand their live thesis.
How long does it take to build an investor outreach list?
A well-researched list of 60 to 80 names takes 15 to 25 hours of founder time, spread over one to two weeks. Founders who try to build it in a weekend usually skip the portfolio scraping and warm-intro mapping steps, both of which are the highest-value pieces. The time invested in list-building is paid back several times over in shorter, better meetings across the raise.
Do I need a warm intro, or is a cold email enough?
For Tier 1 investors (the 10 to 15 names most likely to lead your round), a warm intro is worth waiting for. The response rate gap between warm and cold is large enough that the extra week of intro-hunting pays off. For Tier 2 and Tier 3, well-researched cold emails are a legitimate approach, especially if the email opens with something specific to the partner.
Ready to build the shortlist that will actually close your round?
Finding the right investors is upstream of every other part of your raise. A tighter, better-researched list gets more meetings than a bigger, poorly-researched one. It closes faster, on better terms, with less time wasted.
At RunwayTeam, we have helped over 600 founders raise more than $1.2B by pairing investor targeting with pitch deck and fundraising consulting work. If you are still deciding which investors to approach, or if the meetings you are booking do not feel like they match, book a strategy call and we will build the shortlist with you.
