Twilio

The 30-Second Summary

What is Twilio? A Plain English Definition

Imagine you've just summoned an Uber. A moment later, your phone buzzes with a text: “Your driver, David, is arriving in a blue Toyota.” Or perhaps you're logging into your bank account and receive a text with a verification code. Maybe you've scheduled a telehealth appointment and join a video call directly within the provider's app. In all these scenarios, there's a good chance Twilio is the invisible engine making it happen. Most of us think of companies like AT&T or Verizon when we think about telecommunications. They own the giant towers and physical infrastructure. Twilio, on the other hand, is a new kind of telecom company built for the internet age. It doesn't own cell towers; it owns a massive, global software network that connects to the traditional telecom world. Instead of selling phone plans to you and me, Twilio sells communication building blocks to developers. These building blocks are called APIs (Application Programming Interfaces). Think of an API as a pre-built Lego brick. If a developer at Airbnb wants to let hosts and guests call each other without revealing their real phone numbers, they don't have to build that complex system from scratch. They just use Twilio's “voice call” Lego brick, write a few lines of code, and it works. This makes Twilio the ultimate “B2B” (Business-to-Business) company. It's the ultimate “picks and shovels” play on the digital economy. While other companies are trying to build the next hit app, Twilio is selling them the essential tools they need to communicate with their customers. They provide the plumbing for modern digital interaction, covering:

For an investor, the key is to look past the technical jargon. Twilio is simply a utility company for the app economy. It provides a mission-critical service that is deeply integrated into its customers' products.

Why It Matters to a Value Investor

A value investor's job is to find wonderful businesses at fair prices. The story of Twilio presents a fascinating, and cautionary, tale that touches upon the most critical principles of value investing. 1. The Economic Moat: High Switching Costs This is the most compelling aspect of Twilio from a value perspective. Once a company, large or small, has built Twilio's APIs into the core of its application, it is incredibly difficult and costly to switch to a competitor. It's not like changing your office coffee supplier. It would require a team of expensive software engineers to spend months, or even years, rewriting and testing fundamental parts of their product. This operational headache creates immense “stickiness.” This stickiness, or high switching cost, is a powerful economic_moat. It allows Twilio to retain customers and grow with them over time. As Uber expands to more cities or your telehealth provider serves more patients, their usage of Twilio's services—and the revenue they generate for Twilio—naturally increases. This is measured by a metric called the Dollar-Based Net Expansion Rate, which historically has been very strong for Twilio. 2. The Profitability Puzzle: The Growth-at-All-Costs Hangover Here lies the central conflict for a value investor. For most of its life as a public company, Twilio has been unprofitable on a GAAP basis (Generally Accepted Accounting Principles). 2) During the era of near-zero interest rates, the market cheered for companies that pursued “growth at all costs.” The story was simple: capture market share now, and worry about profits later. Twilio spent aggressively on sales, marketing, and acquisitions, and it paid its employees generously with company stock. For a disciplined investor, this is a sea of red flags:

The investing landscape has now changed. With higher interest rates, Wall Street is no longer patient. It is demanding profit. The key question for a potential Twilio investor is: can this company pivot from its growth-obsessed culture to one of operational discipline and sustainable profitability? 3. Mr. Market and Valuation: From Darling to Discarded In 2021, Twilio's stock was a Wall Street darling, trading at astronomical multiples of its revenue. Then, as the tech bubble burst, the stock price collapsed by over 90%. This is a perfect illustration of Benjamin Graham's “Mr. Market” parable. The manic-depressive Mr. Market was euphoric about Twilio's growth story in 2021, offering to buy shares at any price. Today, he is despondent, focusing only on the lack of profits and offering to sell his shares for a pittance. A value investor's task is not to get swept up in either emotion. The task is to coldly and rationally calculate the business's intrinsic_value. The dramatic price drop doesn't automatically make Twilio a bargain. But it does create the possibility of a bargain. It means the company is now worth a serious look, to see if Mr. Market's pessimism has become so extreme that the stock price is now significantly below the company's long-term value, creating a margin_of_safety.

A Value Investor's Analytical Framework for Twilio

Because Twilio is a company, not a simple ratio, we apply a framework for analysis rather than a formula. This is how a value investor would systematically approach the decision of whether to invest.

The Method

  1. Step 1: Confirm Your Circle of Competence
    • Before anything else, ask yourself: Do I truly understand how Twilio makes money? Can I explain its competitive advantages (the moat) and its risks in simple terms? If the answer is no, the analysis should stop here. Investing outside your circle_of_competence is pure speculation.
  2. Step 2: Scrutinize the Financials for Profitability Clues
    • Ignore the Hype, Follow the Cash: Look past the headline revenue growth number. The key is free_cash_flow (FCF). Is the company generating more cash than it's spending to run and grow the business? In recent years, Twilio has started to generate positive FCF, which is a crucial first step.
    • Gross Margins: Look at the gross margin of the core Communications business. Is it stable or eroding? A stable, high gross margin (typically 50%+) suggests the company has pricing power and isn't in a race-to-the-bottom commodity business.
    • GAAP vs. Non-GAAP: Always be skeptical of “Non-GAAP” or “Adjusted” profits. Find the reconciliation table in their investor reports and see what costs they are excluding. The biggest culprit is usually SBC. A value investor must mentally (or literally) add back the cost of SBC to get a truer picture of profitability.
  3. Step 3: Assess Management & Capital Allocation
    • The Activist Influence: In late 2023, activist investors took a stake in Twilio, pushing for changes to improve profitability. Shortly after, the founder CEO, Jeff Lawson, stepped down. This is a pivotal moment. The new CEO, Khozema Shipchandler, has a background as the company's CFO and is signaling a much stronger focus on operational efficiency.
    • Watch Their Actions, Not Their Words: Is the new management team making smart capital_allocation decisions? Are they cutting unnecessary costs? Are they considering selling non-core assets like the underperforming Segment business? Are they reducing SBC as a percentage of revenue? These actions will speak louder than any press release.
  4. Step 4: Attempt a Conservative Valuation
    • Discounted Cash Flow (DCF): For a business like Twilio, a dcf_analysis is the most appropriate valuation tool. However, it's fraught with uncertainty. The main inputs are future free cash flow growth and the terminal growth rate.
    • Be Conservative: Given the risks, a value investor would use very conservative assumptions. What if growth is only 5-10% per year, not 30%? What if profit margins never reach the levels of more mature software companies? By running a DCF with pessimistic assumptions, you can arrive at a value for the business that gives you a higher probability of being right. If the current stock price is well below that conservative valuation, a margin of safety may exist.

Interpreting the Result

Your analysis will lead you to one of three conclusions:

  1. 1. A Wonderful Business at a Fair Price: You believe the moat is strong, the path to profitability is clear, new management is on the right track, and the current price offers a reasonable return.
  2. 2. A Troubled Business, Even at a Cheap Price: You believe the competition is too fierce, the path to profitability is a mirage, and management cannot execute the turnaround. The business is a “value trap.”
  3. 3. Too Hard Pile: You conclude that the range of possible outcomes is simply too wide to make a rational decision. The uncertainties around competition, AI disruption, and future margins are too great. For a value investor, putting a company in the “too hard pile” is not an admission of defeat; it is a victory of discipline.

A Practical Example: A Tale of Two Segments

To see the principles of capital allocation in action, we can look at the internal struggle within Twilio between its two main businesses.

Business Unit Description Value Investor's Perspective
Twilio Communications The core business: APIs for messaging, voice, video. It is the “plumbing” we've discussed. This is the crown jewel. It has a relatively strong moat, decent gross margins, and is the engine of the company's cash flow. The focus here should be on optimizing for profitable growth.
Twilio Segment The customer data platform acquired for $3.2 billion. It's meant to help companies manage customer data. This was a major bet on moving “up the stack” to offer more value. However, it's a highly competitive market, growth has been disappointing, and it has been a drag on overall profitability. It's a classic example of a potentially poor capital allocation decision.

In early 2024, under pressure from activist investors, Twilio's new management announced they were exploring a sale of the Segment business.

Advantages and Limitations (The Bull vs. Bear Case)

A rational investor must be able to argue both sides of the case before making a decision.

Strengths (The Bull Case)

Weaknesses & Common Pitfalls (The Bear Case)

1)
While Twilio is a technology company, its fundamental business model—providing essential, usage-based services to other businesses—is a concept that value investors can and should be able to grasp before investing.
