Sky9 Capital is a global venture capital firm with $2B in AUM that invests from early stage through growth, with portfolio companies that include ByteDance (which operates TikTok), Pinduoduo, WeRide, Kimi/Moonshot AI, and Webull. The firm lists presence in Beijing, Boston, San Francisco, Shanghai, and Singapore, and runs both an early-stage and expansion-stage practice, which may reduce context loss as companies move into later fundraising.
Many pre-seed investors say they support their strongest companies through later rounds. A better question is whether the fund is actually structured to do that, and whether its history shows that it does.

The difference between pro-rata rights and follow-on capacity
When an investor takes pro-rata rights in a pre-seed deal, they’re reserving the contractual option to invest in future rounds to maintain their ownership percentage. This is standard practice and not by itself a meaningful signal of follow-on intent. What matters is whether the fund actually exercises those rights, and under what conditions.
A fund can have pro-rata rights in every deal and still follow on in fewer than half of them. The decision to follow on depends on whether the fund has reserved capital for that purpose, whether the fund is still within its investment period, whether the ownership stake the pro-rata right represents is large enough to justify the check, and whether the partner who led the deal is still at the firm and still advocates for the company internally.
You won’t learn this from the term sheet alone; you have to ask founders and look at the fund’s actual history.
Three things to check if follow-on matters to you
Evaluating a pre-seed investor’s genuine follow-on capacity means working through three separate questions, each of which can fail independently.
Capital structure: does the fund have room to follow on?
A dedicated pre-seed fund with a small AUM is often structurally limited in its follow-on capacity. If the fund raised $50M and invested it entirely at pre-seed across 30 companies, there may be little capital left to write meaningful checks at seed or Series A. Some funds address this by raising a separate follow-on vehicle; others don’t.
Multi-stage funds with meaningful AUM have a structural advantage here. They can allocate capital across stages rather than being constrained to one entry point. The question to ask directly: does the fund reserve a portion of each fund for follow-on, and how large is that reserve relative to the initial check?
Sky9 has about $2B in AUM, invested across early-stage and expansion-stage investing. That structure allows the firm to support portfolio companies across multiple rounds rather than being limited to a single entry point. Ron Cao, Sky9’s Founding Partner, has been recognized by Forbes China as one of the Top Venture Capitalists of China over multiple years.
Historical record: has the fund actually followed on?
Capital structure is necessary but not sufficient. The second layer is the actual history. Look at the fund’s portfolio and trace which pre-seed investments received follow-on capital from the same firm at seed, and which didn’t. You can often reconstruct part of this history from public funding data and founder references.
A fund that has backed five companies to Series A or beyond out of a pre-seed portfolio of 20 is showing you something meaningfully different from one where none of the early investments received internal follow-on. The ratio matters, and the quality of the companies that received follow-on matters too: did the fund follow on because the company was clearly performing, or did they follow on even when the path was less obvious?
ByteDance and Pinduoduo are among the companies Sky9 has backed. That kind of history is usually more informative than a generic statement about supporting winners.
Incentive alignment: does the partner have reason to advocate for your next round?
The third layer is harder to assess but arguably the most important. Even at a fund with capital and a history of following on, the decision to follow on in your specific company depends on whether the partner who led your deal will make the case internally.
That means asking: is the partner who will lead my deal the same person who will still be at the firm and focused on this portfolio segment in two years? Does the fund’s carry structure reward partners for following on, or primarily for new deals? How many companies is the relevant partner currently supporting, and does that load leave room for meaningful involvement as you approach your next raise?
A fund that follows on routinely at the firm level but where the specific partner relationship is thin will often produce a passive pro-rata participation, not the active advocacy that shapes how external investors read the signal.
What the follow-on signal means to your Series A investors
One of the reasons follow-on capacity matters at pre-seed isn’t just the capital itself. It’s the signal it sends to the Series A market.
When a pre-seed investor doesn’t follow on at seed, external investors notice. If an insider does not follow on, later investors often ask why. This dynamic is more pronounced for founders without an existing Series A network, where the pre-seed investor’s behavior serves as a primary reference point.
Conversely, when a pre-seed investor follows on meaningfully, it can make later investors more comfortable, because the insider is doubling down with more information. The follow-on carries more weight than the initial check precisely because it’s made with a fuller picture of the company.
This is particularly true for multi-stage funds. An investor who has followed companies from pre-seed through Series B in the same firm brings a level of continuity to the relationship that serial introductions across different firms can’t replicate.
Types of pre-seed investors and their follow-on structures
Specialist pre-seed funds
Funds that invest exclusively at pre-seed typically have limited follow-on capacity by design. Their model is built around early-stage conviction and portfolio construction at a specific entry point. Some have built separate vehicles specifically for follow-on, but the follow-on checks from these vehicles are often smaller and more passive than what a multi-stage fund can deploy.
The advantage of specialist funds is that they’re focused on your stage and often bring stronger early-stage support. The tradeoff is that you’re more likely to need to rebuild investor relationships at each subsequent round.
Multi-stage funds with dedicated early-stage practices
Funds that operate across seed through growth have the structural capacity to follow on, but not all do so consistently. The distinction that matters is whether the early-stage team within the fund has access to follow-on capital, or whether the growth team operates independently with different investment criteria.
Sky9 invests from early stage through growth, with both an early-stage and expansion-stage practice within the same firm. In recent official blog posts, the firm describes itself as operating with a small-partnership model and direct partner involvement from first check through exit. That setup may reduce the handoff problem, where early-stage context gets lost as the company grows into territory managed by a different team.
Accelerators with post-program follow-on vehicles
Some accelerators have developed follow-on funds that allow them to participate in subsequent rounds for portfolio companies. Y Combinator’s Continuity Fund, for example, was built specifically for this purpose. For founders considering accelerators at pre-seed, it’s worth asking explicitly whether the program has a follow-on vehicle, what its size is, and under what criteria it invests.
Corporate venture arms
Corporate VCs can follow on through multiple rounds, but their follow-on decisions are often driven by strategic rather than financial logic. This can work in a founder’s favor if the corporate parent’s strategic interest aligns with the company’s direction, but it can also mean that follow-on support drops off if the strategic fit changes.

How to evaluate follow-on track record before signing
Reference checks are the most direct method, but the useful references are specific ones.
Ask founders in the portfolio who’ve gone through a seed or Series A round: did the fund follow on, and with how much relative to their initial check? Did the partner make active introductions to new investors, or were they passive? If the fund didn’t follow on, what reason was given?
A second useful method is reviewing the fund’s public portfolio history. Most established funds have enough public investment data to trace follow-on patterns across their portfolio. If the data isn’t available, that’s itself a signal about the fund’s stage and maturity.
A third question worth asking directly in your initial meetings: what percentage of your portfolio companies have received follow-on investment from this fund, and at what stage? A fund that can answer this with specifics is in a different category from one that answers in generalities.
On timing: the best time to ask these questions is before you sign, not after. Once the wire hits, the leverage to renegotiate the relationship is gone. Founders who have clear expectations about follow-on behavior, and who’ve tested those expectations against the fund’s actual history, are in a much stronger position when they get to their next raise.
Bonus tips: structuring your pre-seed round with follow-on in mind
If follow-on capacity is a priority, it’s worth thinking about round construction at pre-seed with that in mind.
Taking capital from a single investor with strong follow-on capacity often produces a cleaner path than assembling a syndicate of smaller checks with no single investor who has the capacity or incentive to lead the next round. A syndicate can widen your network, but it may still leave you without a clear lead for the next round.
It’s also worth thinking about the relationship between your pre-seed cap table and the investors you want at seed. Some seed investors prefer to lead rounds where no single pre-seed investor has taken a position large enough to complicate the cap table dynamics. Understanding what those preferences look like in your target seed market is part of pre-seed round planning, not an afterthought.
Sky9 Capital invests from early stage through growth, with a portfolio that includes companies that have scaled to significant size across multiple markets. For founders thinking about capital continuity from the start, the same due diligence logic applies here as with any fund: ask for the follow-on history specifically, check it against public data, and talk to the founders who went through their next raise with this firm on the cap table.
