In the high-octane world of finance, the Initial Public Offering (IPO) is a defining moment. It’s a company’s debutante ball, a transition from private ambition to public scrutiny, and a chance for everyday investors to get in on the ground floor of the next potential titan. While headlines are often dominated by household names like Rivian, Snowflake, or Airbnb at their IPO juncture, the most compelling opportunities frequently lie in the shadows, nurtured by quiet, relentless innovation.
These are the “quiet contenders“—companies that have mastered their niche, built robust business models away from the media glare, and are strategically positioning themselves for that pivotal leap into the public markets. For the astute investor or industry observer, identifying these companies before they hit the ticker tape can offer a significant edge.
This article delves into five such under-the-radar US companies, each a leader in its field, each demonstrating the growth, scalability, and market potential that make them primed for a future IPO. Our analysis is grounded in their business fundamentals, market positioning, and the broader economic trends they are riding, providing a foundation of expertise and authoritative insight into the private market landscape.
1. Plaid: The Silent Pulse of Fintech
The Company: If you’ve ever connected your bank account to Venmo, Coinbase, or Robinhood, you’ve likely used Plaid. Founded in 2013 by Zach Perret and William Hockey, Plaid operates the critical data layer that connects financial institutions with fintech applications. They are the invisible pipes that make open banking possible.
Why They Are a Quiet Contender: Plaid doesn’t compete for consumer attention; it empowers the apps that do. This B2B (Business-to-Business) focus has allowed it to achieve staggering scale with remarkable stealth. Its $13.4 billion acquisition deal by Visa in 2020, which was ultimately blocked by the Department of Justice on antitrust grounds, was a watershed moment that revealed its immense value and strategic importance. Remaining independent has only strengthened its position, forcing it to build a more comprehensive and defensible moat.
The Business Model & Market Position:
Plaid’s primary revenue stream comes from API (Application Programming Interface) fees. Every time a user links their financial data through Plaid, the company charges the fintech app a small fee. This creates a powerful network effect: as more fintech apps use Plaid, it becomes more valuable to banks and consumers, and as more consumers use it, it becomes indispensable for fintech apps.
- Market Leadership: Plaid is the dominant player in the US, with connections to over 12,000 financial institutions and used by thousands of fintech companies.
- Expansion Beyond Connectivity: Recognizing the need to diversify, Plaid has launched new products like Plaid Exchange (helping banks build their own secure APIs) and Plaid Signal (for real-time balance and risk assessment), moving up the value chain from simple data connectivity to intelligence and analytics.
The IPO Potential:
The blocked Visa acquisition was, in hindsight, the best thing that could have happened for a potential Plaid IPO. It validated its market position as a critical piece of national financial infrastructure.
- TAM (Total Addressable Market): The global open banking market is projected to grow from $20 billion in 2021 to over $130 billion by 2030. Plaid is at the epicenter of this shift.
- Financials: While private, its reported revenue run-rate has consistently climbed, estimated to be well over $500 million annually. Its valuation in its latest private funding rounds has hovered around $13-14 billion, setting a strong benchmark for a public debut.
- The Narrative: A Plaid IPO would be a blockbuster event, representing not just a company, but the entire fintech ecosystem. It’s a bet on the future of finance being open, connected, and digital.
What to Watch For: Key indicators of an impending IPO will be the appointment of a seasoned CFO with public company experience, further international expansion (particularly in Europe where open banking is regulated), and a clear path to profitability.
2. Stripe: The Engine of the Online Economy
The Company: While Stripe is a behemoth with a $65 billion valuation, it remains a “quiet contender” in the sense that it operates almost entirely in the backend. Founded by Irish brothers Patrick and John Collison in 2010, Stripe provides the economic infrastructure for the internet. Its tools allow businesses of all sizes, from startups to giants like Amazon and Microsoft, to accept online payments, manage revenue, and combat fraud.
Why They Are a Quiet Contender: Despite its size, Stripe’s brand is largely invisible to the end consumer. You don’t “see” Stripe when you buy a coffee; you see the coffee shop. This B2B focus has allowed it to build one of the most formidable and valuable software businesses in the world without the fanfare of a consumer-facing brand. Its decision to remain private for over a decade, while raising colossal private rounds, has only fueled the anticipation for its eventual IPO.
The Business Model & Market Position:
Stripe’s core business is a classic SaaS (Software-as-a-Service) and transaction fee model. It charges a small percentage of each transaction processed through its platform, alongside subscription fees for premium services.
- Developer-First Approach: Stripe’s genius was in designing its API for developers. This bottom-up adoption strategy meant that as startups chose Stripe for its ease of use, they grew with it, embedding it deeply into their operations.
- Expanding the Suite: Stripe is no longer just a payments company. It has built a vast ecosystem including:
- Stripe Connect: For building marketplaces (e.g., Lyft, DoorDash).
- Stripe Capital: For providing business loans to its users.
- Stripe Radar: A machine learning-powered fraud detection tool.
- Stripe Treasury: Banking-as-a-Service APIs.
The IPO Potential:
The Stripe IPO is not a matter of “if” but “when.” It is arguably the most anticipated tech IPO of the decade.
- Financial Scale: Stripe has consistently reported massive revenue, with estimates suggesting it processes hundreds of billions of dollars in volume annually. Its own revenue was reported to be over $12 billion in 2021.
- Market Dominance: Alongside PayPal/Braintree, Stripe dominates the online payments processing market for new businesses. Its valuation makes it the most valuable private company in the US.
- The Narrative: An IPO for Stripe is a bet on the continued growth of the global online economy. As more commerce moves online and more businesses are created, Stripe’s underlying infrastructure becomes more valuable. It’s a foundational pick, akin to buying the picks and shovels during a gold rush.
What to Watch For: Stripe has already taken concrete steps toward an IPO. It hired a new CFO, Dhivya Suryadevara, from GM in 2020, a classic pre-IPO move. It has also been working on a “direct listing” or a traditional IPO. Market conditions in 2024 and beyond will be the final determinant for its debut.
3. Databricks: The AI and Data Architecture Powerhouse
The Company: In the era of Big Data and AI, the ability to process and analyze massive datasets is a superpower. Databricks, founded in 2013 by the original creators of Apache Spark, provides a unified, open platform for data engineering, data science, and business analytics. It’s the “lakehouse” platform that combines the best of data lakes and data warehouses.
Why They Are a Quiet Contender: While a leader in its space, Databricks often operates in the shadow of its more famous competitor, Snowflake, which had a record-breaking IPO in 2020. However, this narrative is shifting rapidly. Databricks has cultivated a fiercely loyal following among data scientists and engineers, building its reputation on technical excellence and its open-source roots, rather than marketing flash.
The Business Model & Market Position:
Databricks operates on a consumption-based SaaS model. Customers pay for the compute and storage resources they use on the platform. This model aligns well with client value but requires sophisticated management to ensure profitability.
- The Lakehouse Paradigm: Databricks’ key innovation is pioneering the “lakehouse” concept. It argues that instead of maintaining separate systems for raw data (data lakes) and structured analytics (data warehouses), companies can have a single, simplified architecture. This is highly appealing for organizations looking to reduce complexity and cost.
- Open Source Credibility: The company was built around Apache Spark, a leading open-source engine for large-scale data processing. This has given it immense credibility and a built-in user base. Its acquisition of Redash and MLflow further solidified its commitment to the open-source ecosystem.
- AI Leadership: With the explosion of Generative AI, Databricks is perfectly positioned. Its platform is used to train, fine-tune, and manage large language models (LLMs), making it an essential tool for companies building their own AI capabilities.
The IPO Potential:
Databricks has been on a direct collision course with Snowflake, and the public markets are eager for a compelling alternative.
- Impressive Financials: In its last reported results before its IPO, Databricks announced it had surpassed $1.5 billion in annual revenue, growing at over 60% year-over-year. It has a strong path to profitability.
- Massive Valuation: Its last private funding round in 2023 valued the company at $43 billion, setting a massive benchmark for its public offering.
- The Narrative: A Databricks IPO is a bet on the future of enterprise AI and data. It represents the architectural shift towards the lakehouse and positions the company as an enabler of the next wave of AI-driven innovation. Investors will see it as a pure-play on the data and AI infrastructure market.
What to Watch For: Databricks has confidentially filed for an IPO. The timing will be closely watched, as it will be a major bellwether for the tech market’s appetite for high-growth, foundational software companies.
4. Chime: The Champion of the Financially Underserved
The Company: Chime is a neobank—a bank without physical branches—that provides fee-free mobile banking services. Its core offerings include a spending account, a savings account, and a secured credit card. Founded in 2013 by Chris Britt and Ryan King, Chime’s mission is to provide financial peace of mind to everyday Americans.
Why They Are a Quiet Contender: While Chime has millions of users, its core demographic is not the traditional Wall Street investor. It has built its empire by serving the “middle class” that is often overlooked by traditional banks—those frustrated by overdraft fees, minimum balance requirements, and poor digital experiences. Its growth has been viral and organic, a grassroots movement in the financial sector.
The Business Model & Market Position:
Unlike Plaid or Stripe, Chime is a B2C (Business-to-Consumer) play. Its revenue model is similar to a traditional bank, but with a modern twist:
- Interchange Fees: The primary revenue driver. Every time a user swipes their Chime debit card, Chime earns a small fee from the merchant’s bank.
- No Hidden Fees: Chime famously avoids the overdraft fees, monthly maintenance fees, and minimum balance fees that plague traditional banks. This is its core value proposition and customer acquisition engine.
- Early Direct Deposit: A key feature that allows users to get their paychecks up to two days early, a powerful benefit for those living paycheck to paycheck.
The IPO Potential:
Chime was on the cusp of an IPO in 2022 but delayed its plans due to adverse market conditions. This delay has only given it more time to solidify its business.
- Massive User Base: Chime is the largest neobank in the US, with an estimated 12-15 million accounts. This kind of scale is incredibly valuable.
- Profitability: Chime has stated it is profitable on a EBITDA basis, a crucial milestone that will be attractive to public market investors wary of cash-burning startups.
- The Narrative: A Chime IPO would be a landmark event for the consumer fintech space. It’s a bet on the disruption of traditional retail banking and the mass adoption of digital-first financial services. It represents a shift in economic power and financial inclusivity.
What to Watch For: The return of favorable market conditions for growth-stage, tech-enabled consumer companies will be the main catalyst. Look for updated S-1 filings and a renewed marketing push as it prepares to tell its story to public investors.

5. Anduril Industries: The Defense Tech Disruptor
The Company: In an industry dominated by century-old “prime” contractors like Lockheed Martin and Northrop Grumman, Anduril is a radical newcomer. Founded in 2017 by Palmer Luckey (creator of Oculus), Anduril builds autonomous defense technology for the US and its allies. Its products include autonomous drones, surveillance towers, and command-and-control software.
Why They Are a Quiet Contender: Defense is a notoriously insular and slow-moving industry. Anduril has broken in by leveraging a Silicon Valley mindset: agile software development, rapid prototyping, and a focus on cost-effectiveness. It operates largely out of the public eye, but its contracts with the Department of Defense and other agencies signal its rising influence.
The Business Model & Market Position:
Anduril sells its hardware and software systems directly to government agencies. Its model is based on selling capability, not just hardware.
- Software-Defined Hardware: The core of Anduril’s products is its Lattice OS, an AI-powered software platform that can fuse data from various sensors (drones, towers, radars) to create a single, real-time picture of a battlefield or border. The hardware is a vehicle for the software.
- Disrupting the Cost Structure: Anduril claims it can develop and field new capabilities at a fraction of the cost and time of traditional defense contractors by using commercial off-the-shelf technology and agile development.
- Major Contracts: It has won significant contracts with the U.S. Special Operations Command, the U.S. Marine Corps, and the UK’s Royal Navy, proving its technology is not just a prototype but is being deployed in critical situations.
The IPO Potential:
An Anduril IPO would be unique, offering public investors a pure-play on the modernization of the military and the rise of “asymmetric” warfare.
- A Massive, Recession-Proof Market: The US defense budget is over $800 billion annually. Anduril is tapping into a small but high-growth segment of this market: autonomous systems and AI.
- Proven Viability: Its recurring revenue from software subscriptions and support, on top of hardware sales, creates a more predictable and scalable business model than traditional defense contractors who rely on one-off projects.
- The Narrative: Investing in Anduril is a bet on two powerful trends: the integration of AI into national security and the disruption of entrenched industrial giants by agile, tech-first companies. It’s a geopolitical and technological wager rolled into one.
What to Watch For: Defense companies have a different path to the public markets. Anduril will likely wait until it has secured a few more massive, multi-year contracts to demonstrate predictable long-term revenue. The political and regulatory environment will also play a significant role in its timing.
Conclusion: The Common Threads of a Future IPO Leader
While these five companies operate in vastly different sectors—fintech, data, consumer banking, and defense—they share common DNA that signals their readiness for the public stage:
- Foundational Technology: Each company provides a critical, foundational layer for its industry. They are not selling a trendy app; they are selling the engine, the pipes, or the security system.
- Product-Led Growth: They have achieved scale primarily through the undeniable utility of their product, creating strong network effects or deeply embedded ecosystems.
- Proven Business Models: They have moved beyond user growth to demonstrate clear, scalable, and defensible revenue models.
- Massive Total Addressable Markets (TAM): They are not niche players in small ponds. They are attacking multi-billion dollar markets with global scope.
- Experienced Leadership: Each is led by founders and executives with a proven track record of execution and vision.
For investors, the lesson is to look beyond the headlines. The next generation of public market giants is being built today, not on the front pages of tech blogs, but in the quiet, relentless work of solving fundamental problems. Plaid, Stripe, Databricks, Chime, and Anduril represent this vanguard, and their journey to the public markets will be one of the most compelling stories in business over the coming years.

FAQ: Understanding IPOs and Quiet Contenders
Q1: What exactly is an IPO?
An IPO, or Initial Public Offering, is the process by which a privately held company offers its shares to the public for the first time on a stock exchange. This transition from private to public allows the company to raise significant capital from a wide pool of investors, provides liquidity for early investors and employees, and increases its public profile.
Q2: Why is it so hard to invest in companies before they IPO?
Pre-IPO investing is typically restricted to “accredited investors”—individuals or institutions that meet specific wealth and income thresholds set by securities regulators like the SEC. This is because private company investments are considered high-risk, illiquid, and lack the disclosure requirements of public companies, making them unsuitable for the general public.
Q3: What are the biggest risks of investing in a company at its IPO?
- Volatility: IPO stocks are often highly volatile in their first days and months of trading.
- Hype vs. Fundamentals: The price can be driven by media hype rather than the company’s underlying financial performance.
- Lock-Up Periods: Early investors and insiders are typically subject to a “lock-up” period (e.g., 180 days) where they cannot sell their shares. When this period expires, a wave of selling can depress the stock price.
- Limited Historical Data: While companies provide prospectuses, there is less public trading history to analyze compared to established public companies.
Q4: How can I, as a retail investor, research potential future IPOs?
- Follow the Tech Press: Websites like TechCrunch, The Information, and Wall Street Journal’s tech section often report on large funding rounds and private company valuations.
- Monitor SEC Filings: The EDGAR database on the SEC website is where companies must file their S-1 registration statement when they confidentially or publicly decide to go public. This document is the primary source of truth about a company’s financials and risks before an IPO.
- Industry Analysis: Understand the broader market trends. Companies in high-growth sectors like AI, fintech, and climate tech are more likely to pursue IPOs.
Q5: Besides these five, what other sectors are ripe for future IPOs?
Several sectors are buzzing with potential IPO candidates:
- Climate Tech & Renewable Energy: Companies focused on carbon capture, grid storage, and sustainable agriculture.
- Biotech & Life Sciences: Particularly those using AI for drug discovery (e.g., Recursion Pharmaceuticals, which has already filed).
- Blockchain & Web3 Infrastructure: While the consumer-facing crypto market is volatile, the underlying infrastructure companies (wallets, security, enterprise blockchain) are building steadily.
- The Future of Work: Platforms focused on remote work collaboration, HR tech, and professional upskilling.
