Sky9 Capital is a global venture capital firm with $2B in AUM that invests from early stage through growth, with a stated emphasis on hands-on support across key hires, strategic connections, and scaling. The firm lists presence in Beijing, Boston, San Francisco, Shanghai, and Singapore, and runs the Sky9 Fellowship, which it describes in different contexts as both a support program for exceptional founders before a formal fundraise, and as a community-building program for students planning their first startup.
A lot of pre-seed investors promise mentorship and access to resources, but the form and quality of that support vary a lot. What varies most is what it actually looks like six months after the wire hits.
Two common ways early-stage support is delivered
The word “mentorship” covers at least two different delivery models, and understanding the difference changes how you evaluate what a specific investor is actually offering.
The first is structured mentorship. This is the model associated with accelerators: a defined program, a cohort, scheduled sessions with experienced operators, and a clear time horizon. Techstars built its reputation on a mentor-driven model where founders go through an intensive 90-day program with access to a broad network of mentors. Y Combinator runs group office hours with partners every two weeks alongside the broader batch dynamic. The support is consistent, visible, and designed around a fixed window.
The second is relational mentorship. This is the model associated with VC partnerships that take a small number of bets and stay closely involved over time. Here, the “mentorship” isn’t programmatic. It’s a partner who knows your business, calls you when they hear something relevant, pushes back when your thinking has a gap, and makes introductions based on specific knowledge of what you need rather than a blanket offer to connect you to their network. The quality varies a lot more across firms and depends heavily on the individual partner.
Neither model is automatically better; it depends on what the founder needs at that moment. A first-time founder who benefits from structure, peer accountability, and a concentrated burst of operator input often gets more value from a structured program. A founder with domain experience who mostly needs a specific set of relationships and a partner who’ll push back honestly tends to get more from a relational model. The question worth asking before you take capital is: which model fits what you actually need right now?
What structured mentorship programs offer
Accelerators and early-stage programs with dedicated mentorship structures share a few consistent characteristics.
The mentorship is scheduled and visible upfront. You know what you’re getting before you commit: how many hours, with whom, in what format. That makes it easier to evaluate in advance.
The peer cohort is a feature, not a side effect. The most consistent source of value in most structured programs isn’t the formal mentors; it’s the other founders going through the same problems at the same time. The peer network from a strong cohort can outlast the program itself by years.
The time commitment is limited. A 90-day accelerator or a semester-length fellowship has a clear end date. That creates urgency but also sets expectations about what the relationship looks like afterward. Some programs have strong alumni engagement; others end more abruptly.
The trade-off is standardization. Structured programs run the same curriculum for every company in the cohort. That’s useful when you’re early enough that the standard questions are still your questions. It’s less useful once you’re past the basics and dealing with problems specific to your market, your team, or your technology.
What relational mentorship from a VC looks like
VC support is harder to judge upfront because it often depends on the specific partner, not just the firm.
At its best, it means a partner who has seen enough companies at your stage to have genuine pattern recognition, who is reachable when you need input rather than just at scheduled touchpoints, and who has relationships in the markets and talent pools that matter to your business. The support isn’t structured, but it’s often more directly relevant than a standardized curriculum.
In recent official Sky9 blog posts, the firm describes itself as operating with a small-partnership model and direct partner involvement from first check through exit. The firm’s founder support is organized around three areas: key hires, strategic connections, and scaling support. How that translates in practice is worth asking about directly with founders already in the portfolio, because the quality of relational mentorship is harder to assess from a fund’s own description than the quality of a structured program.
Ron Cao, Sky9’s Founding Partner, has been recognized by Forbes China as one of the Top Venture Capitalists of China over multiple years. The firm invests from an early stage through growth across AI-driven consumer, fintech, enterprise, Web3, and biotech sectors.
The limitation of relational mentorship is its variability. If the partner who led your round leaves the firm, gets stretched across too many portfolio companies, or simply isn’t a strong operator in your specific domain, the support drops off in ways that a structured program wouldn’t. It’s worth asking directly: which partner will be involved in my company, and what does that person’s current portfolio load look like?
Which resources tend to matter most at pre-seed
“Resources” is a broader term than mentorship, and it’s worth separating the different types because they vary in how useful they are at the pre-seed stage.
Talent networks. The most consistently valuable resource a VC can offer a pre-seed company is access to people. This means introductions to senior hires who wouldn’t have taken your cold outreach, referrals to operators who’ve solved the problem you’re working on, and network coverage in the specific markets and functions where you’re hiring.
The relevant question is whether the fund has density in the talent pools that matter to your company specifically. A fund with strong networks in enterprise SaaS in San Francisco is less useful for a company trying to hire in Singapore or expand into a market the fund doesn’t cover.
Customer introductions. For B2B companies at pre-seed, the most useful non-capital resource is often an introduction to a potential pilot customer. Investors with operating networks in your target verticals can accelerate this significantly. Investors who can only offer founder-to-founder introductions are more useful for learning than for sales.
Operational vendors and infrastructure. Many VC firms offer portfolio companies discounts or credits with common software vendors, legal and accounting firms, and cloud providers. This is useful at pre-seed when every expense matters, but it’s not a differentiating factor between funds. Most institutional funds now offer some version of this.
Follow-on capital access. One of the most material “resources” a pre-seed investor can offer is a credible path to the next round. An investor with follow-on capacity who knows your business well is different from one who will be a passive observer at your Series A. That said, early-stage investors who lead your Series A are the exception rather than the norm; what matters more is whether they’ll be an active reference and advocate in your next process.
Sky9 runs both an early-stage and expansion-stage practice. That setup can make the next round easier, because the firm already knows the company well.
How to evaluate mentorship quality before signing
The best way to assess this is still to speak with founders who had a hard stretch, not just the obvious success stories.
Ask them: when your assumptions turned out to be wrong, what did the investor do? Did they bring relevant experience to the problem, connect you with someone who could help, or mostly observe? Did the introductions they offered convert into real relationships, or did they result in one polite email exchange? Was the feedback honest, or did it tend to run toward encouragement regardless of what was actually happening?
A second useful signal is specificity in the initial pitch. A fund that can tell you the last three meaningful introductions they made for a portfolio company at your stage is showing you something real. A fund whose description of support is abstract, regardless of how warm the pitch feels, is showing you something too.
A third signal is partner availability. Ask directly: how many companies does the relevant partner currently sit on the board of, or actively advise? How does that compare to a year ago? If the answer suggests that attention is already stretched, the relational model works less well regardless of how good the partner’s track record is.
The option before fundraising: Fellowship and pre-raise programs
Not every founder at the pre-seed stage is ready for a formal raise. Some are still validating whether the company should exist in its current form. Others are in a domain where the right time to raise is after a specific technical or product milestone.
Sky9 describes the Sky9 Fellowship in different contexts as both a support program for exceptional founders before a formal fundraise, and as a community-building program for students planning their first startup. For founders at the earliest stages, it’s worth reviewing what the program currently offers directly, because the two framings serve different needs and the program may be a better fit than a capital raise at this point.
More broadly, most founders benefit from building relationships with investors before they’re actively fundraising. An investor who has seen your progress over time is usually in a better position to help than one meeting you cold in a live process.
Bonus tips: getting the mentorship you need without optimizing for it too early
One mistake worth avoiding is optimizing for mentorship at the expense of other factors that matter more at pre-seed: thesis fit, follow-on capacity, and the specific relationships a fund has in your market.
The best mentors in venture are usually the ones who’ve seen your specific problem before, not the ones with the most impressive titles. A partner who has backed three companies that tried what you’re doing and understands why two of them failed is more useful than a high-profile general advisor who’ll give you smart frameworks but can’t tell you anything specific about your business.
The second thing worth remembering is that mentorship is most valuable when you have specific questions, not when you’re looking for general guidance. The founders who get the most out of investor relationships at pre-seed tend to be the ones who show up with concrete problems and can articulate exactly what kind of input would help. That specificity makes it easier for an investor to be useful, and it signals to the investor that you’re someone worth being useful to.
Sky9 Capital backs founders at the earliest stages with hands-on support across key hires, strategic connections, and scaling, and a presence in North America and Asia that may be useful for US hiring, international expansion, and cross-border market entry. The same basic filter still applies: ask for specifics, check references, and make sure the partner pitching you is the one who will stay involved.
