What Founders Get Wrong About Investor Research
By TurboFund Research Team
Fundraising advice tends to focus on the pitch — your deck, your story, your ask. But most rounds don't die in the meeting. They die before the meeting ever happens, in the research phase that determines who you're even talking to.
After watching hundreds of founders go through the process, the same research mistakes come up over and over. Here are the five that cost the most time and the most deals.
Mistake 1: Treating Every Investor Like a Potential Lead
The most common mistake is the simplest: starting with a massive list and hoping something sticks.
Founders pull 200-300 names from a database, write a template with a few merge fields, and start blasting. The logic feels sound — more emails, more chances, right?
The reality: when you email an investor who doesn't invest at your stage, in your sector, or at your check size, you're not just wasting that email. You're training yourself to expect a low response rate, which makes you send even more emails, which dilutes your effort further.
What to do instead: Start with a strict filter. Stage, sector, check size, geography. Your initial list should have 30-50 names, not 300. If you can't explain in one sentence why each investor is a fit, they shouldn't be on the list.
Mistake 2: Ignoring Portfolio Overlap
This is the single highest-leverage thing you can check about an investor, and most founders skip it entirely.
An investor's portfolio tells you:
- What they actually care about (not what their website says — what they put money into)
- Whether they have competitive conflicts (if they backed a direct competitor, they're not investing in you)
- Your personalization angle ("I noticed you invested in [Company X], we're tackling [related problem]" is the most effective cold email opener that exists)
Portfolio overlap isn't just a filter — it's your pitch strategy. When you know an investor already understands your market because they have 2-3 companies in adjacent spaces, your email can skip the market education and go straight to what makes you different.
What to do instead: For every investor on your shortlist, check their last 15-20 investments. Look for companies in your sector, your business model, or your customer segment. If there's overlap, lead with it. If there's a direct competitor, remove them from the list. If there's nothing related, move them to a lower tier.
Mistake 3: Emailing the Wrong Person at the Fund
Most cold emails go to the managing partner. Most managing partners at funds with more than two people don't source deals through cold inbound. They have principals, associates, and scouts for that.
The person most likely to read your cold email — and most motivated to champion a new deal — is usually one or two levels below the name you recognize. They're the ones who need to find the next breakout company to build their track record. Your email is an opportunity for them, not an interruption.
What to do instead: Research the team, not just the fund. Find the person who sources deals at your stage. On a fund's website, they're usually listed as Principal, VP, or Associate. Check their LinkedIn — if they're posting about your sector, even better. Email that person. If you do get a meeting, the partner will be in the room when it matters.
The exception: solo GPs and very small funds (1-2 partners). There, the managing partner is the sourcing team. Email them directly.
Mistake 4: Not Tracking Outreach Status
This sounds basic. It is basic. And it's still the reason founders miss follow-ups, double-email investors, and lose track of warm intros.
Here's what typically happens: a founder starts the raise with a Google Sheet. Week one, it's organized. Week three, there are 60 rows, half are color-coded in a system they've already forgotten, follow-up dates are scattered, and they just realized they emailed the same partner twice through two different intro paths.
Fundraising is a multi-week process with dozens of parallel conversations happening at different speeds. Without a system, things fall through cracks. And in fundraising, a missed follow-up or a double-email doesn't just cost you one deal — it costs you your credibility with that investor permanently.
What to do instead: Use a pipeline. It doesn't have to be complicated, but it needs three things:
- Status tracking — where is each investor in your process? (Researching → Contacted → Replied → Meeting → Diligence → Pass/Commit)
- Follow-up dates — when did you last reach out, and when is the next touch due?
- Notes — what did they say? What were their concerns? What did they ask for?
Update it after every interaction. It takes 30 seconds and saves you from the chaos that derails most fundraises in week 3.
Mistake 5: Spending Weeks on Research That Should Take Hours
The last mistake isn't about doing research wrong — it's about taking too long to do it right.
Some founders spend 2-3 weeks in "research mode" before they send a single email. They're checking every LinkedIn profile, reading every blog post, cross-referencing three databases for check sizes that are probably out of date anyway. They tell themselves they're being thorough. What they're actually doing is procrastinating on the part that scares them: hitting send.
The research phase should take a day or two, not a month. You need five things for each investor: stage fit, sector fit, check size, portfolio overlap, and the right contact. That's it. You don't need to read their entire Medium archive.
What to do instead: Set a time limit. Give yourself one day to build your shortlist of 30-50 investors, fully researched. If you can't get there in a day with your current tools, the problem is the tools, not your speed.
The best founders we've watched treat research like a sprint: intense, focused, and finished. Then they move immediately to outreach while the research is fresh and their energy is high.
The Common Thread
Every one of these mistakes has the same root cause: treating fundraising like a volume game instead of a targeting game.
Volume feels productive. You can measure it — emails sent, investors contacted, intros requested. But volume without targeting just generates noise. And noise is what makes founders burn out on fundraising before they get to the conversations that actually matter.
The fix is straightforward: spend more time on fewer investors, research each one properly, personalize your outreach, and track everything. It's less exciting than blasting 300 emails, but it's what actually works.
Do the Research Right
The research mistakes above all share one other thing in common: they're fixable with better tooling. Checking portfolio overlap, finding the right contact, filtering by stage and sector — this is exactly the kind of work that should take minutes, not days.
