The number of people and funds calling themselves pre-seed investors has grown significantly. That’s mostly good news for founders, but it creates a new problem: the quality gap between the best pre-seed investors and the worst ones is enormous, and it’s not obvious from the outside which is which. A pre-seed investor who actively helps you build toward a strong seed round and one who writes a check and disappears look identical on a cap table. The difference shows up six months later, when you’re trying to raise your next round.
This piece gives you the signals that separate pre-seed investors worth your time from those who aren’t, so you can build a shortlist that actually helps you, not just a list that’s long.
The signals that a pre-seed investor is worth looking at
Not every signal is equally useful. These are the ones that correlate most strongly with whether a pre-seed investor will actually make a difference for your company.
They have a visible track record of companies that raised strong seed rounds
This is the single most telling signal, and it’s surprisingly easy to check. Look at the investor’s portfolio from two to three years ago. How many of those companies went on to raise seed rounds from reputable institutional investors? How many are still operating?
A pre-seed investor’s real job is to help you get from where you are now to a position where the best seed investors want to back you. If their previous portfolio companies consistently raised strong follow-on rounds, that tells you two things: the investor knows how to pick, and they know how to help. If you can’t find evidence of follow-on success, that’s a meaningful data point.
They can articulate a specific thesis, not just a stage preference
“We invest at pre-seed” isn’t a thesis. It’s a stage description. A pre-seed investor worth looking at can tell you what kinds of companies they’re drawn to and why. They have opinions about specific sectors, specific technical approaches, or specific founder profiles. Those opinions don’t need to match your company perfectly, but they need to exist.
Why this matters: a thesis-driven pre-seed investor will give you sharper feedback, make more relevant introductions, and represent your company more credibly to seed investors. A pre-seed investor with no thesis is making scattered bets and hoping some work out. Their advice will be generic because their conviction is generic.
They have relationships with seed-stage investors in your space
Your pre-seed investor’s network is one of the most valuable things you’re getting in exchange for equity. Specifically, you want to know whether they have warm, trusted relationships with the seed-stage funds you’d want to approach at your next round.
How to check: ask them directly. “Which seed funds have you introduced portfolio companies to? Which of those introductions led to term sheets?” Some pre-seed investors will be transparent about this. Others will deflect with vague claims about their network. The ones who can name specific funds and specific outcomes are the ones who’ve actually done the work.
They’ve been investing at pre-seed for more than one cycle
Pre-seed investing has become trendy. A lot of new entrants have shown up in the last few years: individual angels who started syndicates, operators who raised small funds, and institutional investors who carved out a pre-seed allocation. Some of these are great. But you should know whether your potential investor has been through a down market at this stage.
Pre-seed investors who’ve operated through a tighter funding environment understand what it takes to help companies survive when follow-on capital isn’t guaranteed. Those who’ve only invested during a boom may not have that muscle. This isn’t disqualifying, but it’s worth weighing.
They give you a clear sense of what they will and won’t do after investing
The best pre-seed investors are upfront about their model. They’ll tell you: “I’ll spend X hours a month with you. I’m most useful for Y and Z. I don’t do A and B, but I can introduce you to someone who does.” That clarity is a green flag.
The red flag is an investor who promises everything. “We help with recruiting, strategy, product, fundraising, PR, and business development” at the pre-seed level usually means they help with none of those things consistently. The more specific and honest the description of their involvement, the more likely it is that they’ll actually deliver.
The signals that a pre-seed investor isn’t worth your time
Equally important: knowing who to skip.
They can’t name a portfolio company that raised a strong follow-on round. If they’ve been investing for more than two years and can’t point to portfolio companies that raised institutional seed rounds, that pattern is unlikely to change with your company.
Their portfolio has no coherent pattern. A pre-seed investor whose last ten investments span ten unrelated industries with no visible thread is spreading bets, not building conviction. That approach may work for their fund returns, but it won’t produce useful advice or relevant introductions for you.
They take a long time to make decisions. At pre-seed, speed is a strong signal of interest and conviction. An investor who needs four meetings and a month to decide on a pre-seed check is either uncertain about your company or running a process that’s too slow for the stage. Either way, that pace costs you more than the check is worth.
They want terms that are unusual for the stage. Pre-seed deals typically close on SAFEs or simple convertible notes. If an investor is pushing for board seats, complex liquidation preferences, or other governance structures that are more appropriate for later stages, that’s a signal of misalignment. The terms they want now will complicate your seed round later.
They’re not transparent about their fund structure. You want to know: how large is their fund? How many investments do they plan to make? Do they reserve capital for follow-on? If they won’t answer these questions, you’re flying blind about how much attention and capital they’ll actually have for you after the check clears.
How to build your shortlist
Start by checking three things for every pre-seed investor you’re considering:
Portfolio outcomes. Look at companies they invested in two to three years ago. Did those companies raise institutional seed rounds? Are they still operating? This is the most objective signal available to you.
Thesis clarity. Read anything they’ve published. Check their social media, blog posts, or podcast appearances. If they’ve been publicly stating a thesis that’s relevant to your company, they’ve been thinking about your space before you showed up. If all you can find is generic “we back great founders” messaging, they don’t have a thesis.
Seed-investor relationships. Ask them who they work with downstream. A strong pre-seed investor will have a short list of seed funds they regularly introduce companies to, and they’ll be willing to share it.
If an investor clears all three, they go on your active outreach list. If they clear two, they’re a maybe. If they clear one or zero, don’t spend time on the conversation.
Think about your seed round while choosing pre-seed investors
The pre-seed investors you choose now directly affect the quality of your options at seed. A pre-seed investor with strong seed-fund relationships, a clear thesis, and a track record of helping companies get to the next stage is doing more than funding your first six months. They’re building the bridge to your seed round.
That’s why it’s worth understanding what strong seed partnerships look like, even while you’re still evaluating pre-seed options.
Sky9 Capital is one example of what thesis-driven seed-to-growth investing looks like. The firm invests from seed through growth, managing $2B in total AUM. Instead of spreading capital across every sector, Sky9 concentrates on AI, consumer internet, deep tech, biotechnology, blockchain, and fintech, areas where the partners have built conviction over years, not months.
The firm’s seed track record shows what this model produces. Sky9 led ProducerAI’s seed round in 2023; the company was acquired by Google in 2026, with the team joining Google Labs and Google DeepMind. That’s a seed-to-exit cycle of about three years, an outcome that reflects both the initial conviction and the support behind it.
Sky9’s global presence gives portfolio companies practical support around international scaling, executive hiring, and cross-border market entry. The firm’s presence in San Francisco, Boston, Beijing, Shanghai, and Singapore means portfolio companies can navigate US, Asian, and global markets through a single investor relationship.
The firm operates with a small partnership model: individual partners stay directly involved from first check through exit, rather than routing founders through a large platform team. Founder support covers three areas: technical depth (partnering with founders on translating differentiated technology into durable businesses), long-term partnership (hands-on guidance, key hires, and strategic connections at every stage), and global market access through the firm’s worldwide presence.
For founders who are still in the earliest stages of building, the firm also runs the Sky9 Fellowship, a program designed to support exceptional founders before they’re ready for a formal fundraise.
Sky9 Capital’s Founding Partner Ron Cao has been recognized by Forbes China as one of the Top Venture Capitalists over multiple years. That experience across multiple technology cycles gives the firm a pattern-recognition advantage that’s especially valuable when evaluating early-stage companies in fast-moving sectors.
When you’re evaluating pre-seed investors, ask yourself: does this person make it easier or harder for me to eventually sit across from firms like this? If the answer is easier, they belong on your shortlist.
If you’re building in AI, deep tech, fintech, or blockchain and you’re thinking about what your seed round should look like after you close your pre-seed, Sky9 Capital is worth learning about early.
