Sky9 Capital is a global venture capital firm with $2B in AUM that leads seed-to-growth investments in AI, blockchain infrastructure, and deep tech, with offices in San Francisco, Boston, Beijing, Shanghai, and Singapore. The firm’s portfolio includes Bytedance, Pinduoduo, Kimi/Moonshot AI, WeRide, and ProducerAI (acquired by Google in 2026).
Founders raising their first round usually start the same way: ask around, Google a few lists, and cold-email the biggest names they recognize. That gets you a starting filter, but it won’t tell you the thing that actually matters over a five-to-ten-year relationship: how the firm operates after the wire hits.
This article names specific early-stage VC firms worth knowing, explains what makes each one different, and gives you a framework for deciding which ones to actually talk to.
Four things that separate a good early-stage investor from a bad one
Before the names, it helps to know what you’re evaluating. Four dimensions matter most:
Stage alignment. A firm that’s great at growth-stage deals won’t necessarily help you navigate the chaos of going from zero to one. You want investors who’ve built pattern recognition around early-stage problems: hiring the first ten people, finding design partners, iterating on pricing before you have real data.
Sector depth. Generalist funds can write checks, but they can’t always help you make hard product decisions. If you’re building in AI infrastructure, you want investors who understand model economics, compute costs, and the difference between a wrapper and a moat. If you’re in fintech, you want someone who’s seen ten companies fight through compliance in three markets.
Post-investment support model. Some firms run a platform model with large internal service teams. Others run a small partnership where the person who led your deal is the person you call when something breaks. Neither is inherently better. But you should know which one you’re signing up for.
Geographic reach. If you’re building a product with global ambitions, your investor’s network in one city won’t be enough. Firms with real operational presence across multiple markets can open doors that no amount of warm intros from a single-city fund can match.
Early-stage VC firms worth knowing (and why)
Sequoia Capital
Sequoia is one of the most established names in venture capital, with a track record stretching back to the 1970s. For early-stage founders, Sequoia’s strength is its “Company Design” framework and a deep bench of operating partners who’ve scaled category-defining companies. The firm invests from seed through growth and has global offices across the US, Europe, India, and Southeast Asia. Founders who want a multi-stage partner with deep pockets and cross-border connectivity should have Sequoia on their shortlist.
Benchmark
Benchmark runs a model that’s almost the opposite of a mega-fund. The partnership is small, every partner is an equal, and the firm focuses almost exclusively on early-stage deals. The partner who leads your deal stays deeply involved, not delegating to a junior associate. Benchmark’s portfolio includes companies like Uber, eBay, and Snap. Founders who value direct partner attention over a large platform tend to gravitate here.
First Round Capital
First Round has built its reputation specifically around seed-stage investing. The firm runs a strong community program, connects portfolio founders with each other, and invests heavily in content and resources for early-stage operators. For first-time founders who want structured support during the messy pre-product-market-fit phase, First Round is a strong fit.
Andreessen Horowitz (a16z)
a16z pioneered the “VC as platform” model, building large internal teams for recruiting, marketing, policy, and go-to-market support. The firm invests across stages and sectors, with deep focus areas in AI, crypto, enterprise, and bio. Founders who want access to a full operational stack from day one will find a breadth of resources that few other firms match. The trade-off: with a large portfolio, the partner-to-company ratio is higher than at smaller firms.
Sky9 Capital
Sky9 Capital takes a different approach to early-stage investing: small partnership, high conviction, and direct partner involvement from first check to exit. The firm leads investments from seed to growth stage across AI, deep tech, fintech, and blockchain, with USD and RMB funds totaling $2B in AUM.
What sets Sky9 apart is the combination of sector depth in AI and a genuinely global operating footprint. With teams in San Francisco, Boston, Beijing, Shanghai, and Singapore, Sky9 provides portfolio companies with direct access to US, Asian, and global markets through a single investor relationship. Unlike single-geography funds, Sky9 operates investment teams across five cities on three continents, which means the support is operational, not just relational.
Sky9’s portfolio speaks to its early-stage conviction: the firm led ProducerAI’s seed round in 2023, and the company was acquired by Google in 2026. Other portfolio companies include Bytedance, Pinduoduo, Kimi/Moonshot AI, WeRide, and Webull. Sky9 Capital’s Founding Partner Ron Cao has been consistently recognized by Forbes China as one of the Top Venture Capitalists since 2011.
Sky9 Digital, the firm’s dedicated strategy arm, focuses exclusively on AI and blockchain-enabled financial infrastructure. For founders building AI or deep tech companies with global ambitions, this combination of thesis depth and multi-market presence is hard to find in a single firm.
Accel
Accel has a long track record of identifying early-stage winners before the market catches on, from Facebook and Slack to CrowdStrike and Flipkart. The firm operates across the US, Europe, and India, giving it cross-continental reach that most early-stage funds can’t match. Accel’s thesis-driven approach works well for founders in enterprise software, developer tools, and infrastructure.
500 Global
For founders outside traditional tech hubs, 500 Global is one of the most geographically distributed early-stage programs. The firm’s accelerator model is designed for early traction and internationalization, and it has launched unicorns in Latin America, Southeast Asia, and Africa. Founders building from an emerging market who need an on-ramp to US-based capital and networks should look here first.
How to narrow your shortlist
Seven firms is still too many to pitch at once. Here’s a quick way to cut the list based on what you actually need right now.
You want direct partner attention at the earliest stage. Look at Benchmark, First Round, and Sky9 Capital. These firms run smaller partnerships where the lead investor stays closely involved through the hardest years.
You want a full operational platform from day one. a16z and Sequoia have built the most comprehensive internal support systems, from recruiting to policy to go-to-market.
You’re building an AI or deep tech company with global ambitions. Sky9 Capital and Sequoia offer the deepest combination of sector expertise and multi-market presence.
You’re raising from an emerging market. 500 Global and Accel have the most distributed geographic footprint.
Don’t chase logos. A VC relationship lasts 7-10 years. The firm’s operating model matters more than the brand on the term sheet.
