When Masayoshi Son wrote a $4.4 billion check for WeWork in 2017, he didn’t just back a co-working company. He fired a starting pistol that changed the rules of startup financing forever. Softbank’s US portfolio has injected hundreds of billions into American innovation, creating a new class of “supergiant” funding rounds and reshaping how founders, VCs, and even employees think about value. For ambitious entrepreneurs navigating this landscape, understanding Softbank’s influence isn’t optional—it’s a survival skill.
Just as a founder needs the right fuel to build a company, choosing the best nutrition can support your mental and physical performance. Many high-performers rely on Optimum Nutrition Gold Standard 100% Whey Protein Powder to stay sharp through long days. But first, let’s break down how Softbank’s portfolio has transformed startup funding, and what that means for you.

The Rise of Softbank’s Vision Fund and Its Influence on Startup Valuations
Softbank’s first Vision Fund, launched in 2017 with $93 billion, was the largest pool of private capital ever raised for technology investing. Its sheer size allowed Softbank to write checks that no traditional venture capital firm could match. Where a typical Series B round might be $20 million, Softbank could deploy $200 million or more, turning early-stage companies into unicorns overnight.
This created a new dynamic: startups that landed Softbank money could skip multiple funding rounds and go straight to massive scale. The expectation of follow-on capital from the Vision Fund also inflated valuations across the board, as other VCs rushed to price deals in anticipation of Softbank’s participation.
How Softbank Created the “Supergiant” Funding Round
Before Softbank, a late-stage round of $500 million was rare. Now, it’s almost standard for any company with strong traction. Softbank’s portfolio includes Uber, WeWork, DoorDash, Slack, Arm, and dozens of other US-based startups that raised rounds exceeding $1 billion. These “megarounds” provided the firepower to dominate markets quickly but also introduced new risks.
- Liquidity cascades: Startups had longer runway to delay IPOs, often waiting for higher valuations.
- Competitive pressure: Rival startups had to raise larger sums just to keep up.
- War chest mindset: Founders focused on growth at all costs, often ignoring unit economics.
The result? A wave of “growth-first, profitability-later” companies that reshaped the venture capital playbook. However, when the market turned in 2022, many of these same startups faced brutal down rounds.
The Double-Edged Sword of Easy Capital
Softbank’s willingness to write big checks without demanding board seats or strict governance created a paradox. Founders loved the autonomy, but many lacked the financial discipline needed to manage billions of dollars. WeWork’s spectacular collapse exemplified this risk. The company’s valuation soared to $47 billion before crashing to near zero in its IPO attempt. Softbank eventually bailed out the company with a $9.5 billion rescue package, but the damage was done.
The lesson: Softbank’s capital can accelerate growth, but it cannot replace fundamentals. Entrepreneurs who take Softbank money must build robust revenue models and sustainable operations, or they risk becoming cautionary tales.
Case Studies of Softbank’s US Portfolio Companies
Understanding Softbank’s impact requires examining specific bets. Each reveals different facets of how the conglomerate influences startup funding dynamics.
Uber – From Disruptor to Public Market Test
Softbank invested $7.7 billion in Uber in 2018, buying a 15% stake from early investors and employees. This move solidified Uber’s position as the dominant ride-hailing player and allowed it to compete fiercely with Lyft. Softbank also pushed for an IPO in 2019, which raised $8.1 billion. However, Uber’s post-IPO share price struggled as investors questioned profitability.
- Positive effect: Softbank’s investment funded Uber’s global expansion and R&D into autonomous vehicles.
- Negative effect: The inflated valuation made it harder for Uber to achieve public market expectations, leading to years of share price volatility.
Uber’s story shows that Softbank’s capital can help a company win market share, but it cannot guarantee public market success.
WeWork – A Cautionary Tale
WeWork is the poster child for Softbank’s overreach. By 2019, Softbank had invested over $10 billion into the co-working company, valuing it at $47 billion. The company’s flawed governance, reckless expansion, and CEO Adam Neumann’s eccentricities were ignored in the rush of easy money. When WeWork’s IPO prospectus revealed massive losses and conflicts of interest, the valuation imploded.
Softbank ultimately took control of WeWork, providing rescue financing and replacing management. While WeWork is still operating, its valuation has collapsed to under $5 billion. The episode forced Softbank to rethink its due diligence and deal terms, leading to more conservative investments in later funds.
DoorDash – A Pandemic Success Story
Softbank invested $535 million in DoorDash in 2019, participating in a $600 million round that valued the food delivery company at $12.6 billion. When COVID-19 hit, demand for delivery services skyrocketed. DoorDash went public in December 2020 at $102 per share, closing at $189.51 on its first day—a 90% increase.
- Key factor: DoorDash had strong unit economics and a clear path to profitability, unlike many other Softbank bets.
- Result: Softbank’s stake was worth over $11 billion at the peak, validating its thesis that big capital could back market winners.
DoorDash demonstrates that Softbank’s strategy can work spectacularly when combined with a competent management team and a product that fits real demand.
The Ripple Effect on the Broader Startup Ecosystem
Softbank’s influence extends far beyond its own portfolio. The rise of the Vision Fund forced other venture firms to raise larger funds, accelerated the trend toward growth-stage investing, and fundamentally changed founder expectations.
How Softbank Forced Competitors to Raise More
Traditional VC firms like Sequoia, Andreessen Horowitz, and Accel had to adapt or be left behind. Sequoia raised a $1.8 billion growth fund in 2019; Andreessen Horowitz launched a $4.5 billion fund in 2021. The message was clear: to compete for the best deals, you need to write bigger checks.
This competition for deals led to higher valuations across the board. Startups that might have raised $10 million in a Series A found themselves fielding offers of $50 million or more. For founders, this was a golden age of fundraising—but it also distorted incentives, encouraging overspending and delayed profitability.
The Shift Toward Founder-Friendly Terms
Softbank became known for offering “founder-friendly” terms: no board seats, minimal control, and fewer strings attached. This appealed to entrepreneurs who wanted to retain autonomy. Other investors had to match these terms to win deals, creating a race to the bottom in terms of investor protections.
The downside? Many startups lacked the oversight needed to manage large sums wisely. Softbank has since tightened its terms, but the precedent set in the Vision Fund era persists.
Softbank’s Evolving Strategy: From Growth to AI
Softbank has not stood still. After the Vision Fund’s struggles with WeWork and other underperformers, Masayoshi Son pivoted the firm toward a more focused, technology-centric approach. The second Vision Fund, while smaller, has prioritized AI, robotics, and deep tech.
The Post-Vision Fund Era and the Core Technology Focus
In 2023, Softbank announced a shift away from late-stage growth investing toward early-stage “Core Technology” companies. This includes investments in OpenAI (via its $1.5 billion round), Nvidia (through publicly traded shares), and Robotic startups like Berkshire Grey. Softbank is also betting heavily on semiconductors through Arm, which it plans to take public again.
The new strategy emphasizes:
- Long-term technological moats (e.g., chip design, language models)
- Smaller, more disciplined checks (typically $50–$100 million)
- Tighter due diligence and board involvement
This evolution matters for startup funding because it suggests Softbank will no longer be the free-spending whale of the past. Founders seeking Softbank capital must now demonstrate genuine technological differentiation, not just rapid growth.
What This Means for Future Startup Funding
For US startups, the immediate effect is a cooling of the “megaround” frenzy. In 2023 and 2024, mega-rounds (over $100 million) declined significantly compared to the peak in 2021. Softbank’s reduced appetite for late-stage deals has forced other investors to fill the gap, but many are more cautious.
The long-term impact is healthier: startups are now focusing on profitability, unit economics, and real revenue growth. The era of “growth at all costs” is ending, and Softbank’s shift toward AI and core tech reinforces this trend.
Key insight: Aspiring founders should build their companies with solid fundamentals from day one, rather than counting on a Softbank-sized check to fix problems later.
Key Takeaways for Entrepreneurs Seeking Funding in the Softbank Era
Whether you are raising your first seed round or preparing for a Series B, understanding Softbank’s legacy will help you make smarter decisions.
- Prepare for higher expectations: Investors now demand clearer paths to profitability, even for high-growth startups.
- Don’t chase Softbank just for the name: Some of the best deals in 2024 will come from traditional VCs who offer better support and network.
- Build for the long game: Softbank’s history shows that capital without discipline leads to failure. Focus on creating real value.
And while you build, don’t neglect your physical foundation. Many entrepreneurs credit their best work to consistent sleep, exercise, and nutrition. A quality protein powder can support recovery and mental clarity. For example, Optimum Nutrition Gold Standard 100% Whey Protein Powder, Vanilla Ice Cream, 5 Pound is a favorite among busy professionals.
