Twilio Headquarters & Office Locations: Full 2026 Directory

Twilio is headquartered at 101 Spear Street, San Francisco, CA 94105 — but the company's real operational footprint is spread across six countries, with engineering, sales, and support hubs on three continents. If you're trying to reach the right Twilio team, understand their corporate structure, or benchmark a communications platform competitor, this directory covers every confirmed location as of 2026.

Where is Twilio headquartered?

Twilio's headquarters is at 101 Spear Street, Suite 500, San Francisco, California 94105. The building sits in San Francisco's Financial District, near the Embarcadero waterfront. Twilio has been based in San Francisco since its founding in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis.

The San Francisco office serves as Twilio's legal registered address and houses executive leadership, investor relations, and core go-to-market functions. It is not, however, Twilio's largest office by headcount — that distinction belongs to Bengaluru, which hosts a significant share of the company's global engineering and customer support workforce.

Twilio went public on the New York Stock Exchange in June 2016 under the ticker TWLO, and its SEC filings consistently list the Spear Street address as the principal executive office. For any formal business correspondence, legal notices, or vendor registration, this is the address to use.

What are Twilio's offices in North America?

Beyond San Francisco, Twilio maintains several North American locations that serve distinct functional roles. After the 2022 restructuring that cut approximately 17% of its workforce, Twilio consolidated a number of smaller satellite offices — but the core hubs remain active.

San Francisco, CA — Global HQ

Address: 101 Spear Street, Suite 500, San Francisco, CA 94105
Function: Executive leadership, legal, finance, investor relations, go-to-market strategy
Notable: Primary registered address for SEC filings and corporate legal correspondence.

New York, NY

Address: 375 Park Avenue (Park Avenue Tower), New York, NY 10152
Function: Enterprise sales, partnerships, East Coast customer success
Notable: Twilio's New York presence is heavily sales-focused, serving its large financial services and media customer base concentrated in the Northeast.

Denver, CO

Function: Engineering, product, and Segment (Twilio's customer data platform) teams
Notable: Denver became a significant engineering hub following Twilio's $3.2 billion acquisition of Segment in 2020. Many former Segment employees are based here.

Irvine, CA

Function: Engineering and product development
Notable: The Irvine office houses teams working on Twilio's core communications APIs, including Voice, SMS, and WhatsApp Business integrations.

Austin, TX

Function: Sales, customer success, and support
Notable: Austin has grown as a secondary sales hub as Twilio expanded its mid-market and SMB coverage in the South and Southwest US.

Where are Twilio's international offices?

Twilio's international footprint reflects its position as a global communications infrastructure provider. The company has concentrated its non-US presence in three regions: Western Europe (for EMEA sales and compliance), Ireland (for EMEA legal entity and engineering), and Asia-Pacific (for engineering scale and regional sales).

London, United Kingdom

Address: 25 Canada Square, Canary Wharf, London E14 5LQ
Function: EMEA headquarters, enterprise sales, partnerships, government affairs
Notable: London is Twilio's most important non-US commercial office. The EMEA sales leadership team is based here, and the office handles strategic accounts across Europe, the Middle East, and Africa.

Dublin, Ireland

Function: EMEA legal entity, engineering, finance, and compliance
Notable: Like many US tech companies, Twilio uses Dublin as its European legal and tax headquarters. The Dublin office also houses engineering teams and is a key site for GDPR compliance operations.

Tallinn, Estonia

Function: Engineering
Notable: Twilio maintains a smaller engineering presence in Tallinn, part of a broader strategy to access European engineering talent outside major hub cities.

Singapore

Function: APAC headquarters, sales, partnerships, customer success
Notable: Singapore serves as Twilio's Asia-Pacific commercial hub. The office covers strategic accounts across Southeast Asia, Australia, and Japan.

Bengaluru, India

Function: Engineering, product, customer support, and operations
Notable: Bengaluru is one of Twilio's largest offices globally by headcount. The office houses significant engineering capacity across core platform, infrastructure, and Segment product lines, as well as a large 24/7 customer support operation.

Tokyo, Japan

Function: Sales and customer success for Japan market
Notable: A smaller office serving Twilio's Japanese enterprise customers, where local language support and relationship-based sales are essential.

"The geographic distribution of Twilio's workforce — with major engineering centres in Bengaluru and Dublin alongside its US hubs — reflects a broader industry shift toward distributed R&D models that reduce concentration risk and access global talent pools simultaneously."

— Gartner, Market Guide for Communications Platform as a Service, 2024

Is Twilio remote-first or office-based?

Twilio is explicitly remote-first. The company announced its "Remote-First" policy in 2020, well before the broader tech industry debate about return-to-office, and has maintained that stance through multiple restructuring cycles.

In practice, this means the majority of Twilio's global workforce is distributed and not tied to any specific office location. Offices function as collaboration hubs for team offsites, customer meetings, and in-person work for employees who prefer it — not as mandatory daily workplaces.

This remote-first posture has real implications for anyone trying to engage Twilio employees or understand its organisational structure. A job posting listed as "San Francisco" may not require physical presence; a sales role listed as "New York" may be covering the entire East Coast from anywhere. LinkedIn's talent research has consistently shown that remote-first companies like Twilio draw from a far wider geographic talent pool than their office locations suggest.

According to Twilio's investor relations filings, the company recognised approximately $1.1 billion in real estate lease impairments and restructuring charges across 2022–2023, partly tied to office footprint reduction as it committed more deeply to distributed work.

What teams are based at Twilio's San Francisco HQ?

The San Francisco headquarters houses Twilio's executive leadership team, including the CEO, CFO, and Chief Legal Officer. Beyond the C-suite, the HQ concentrates functions that benefit from proximity to investors, legal counsel, and the broader San Francisco enterprise tech ecosystem.

Functions concentrated at SF HQ

• Executive leadership: CEO, CFO, CLO, and direct reports
• Investor relations: All SEC filings, earnings calls, and institutional investor engagement
• Legal and compliance: Corporate legal, intellectual property, M&A
• Finance: Corporate finance, treasury, and accounting leadership
• Brand and communications: PR, analyst relations, and corporate marketing leadership
• West Coast enterprise sales: Strategic accounts in the Bay Area and Pacific Northwest

Engineering and product teams at HQ are smaller than they once were — much of that function has migrated to Denver (Segment), Bengaluru, and Dublin over the past four years. The SF office retains product leadership and platform strategy roles, but individual contributor engineering work is largely distributed.

How do sales teams use Twilio's office presence for prospecting?

Knowing where Twilio operates matters less than knowing who is using Twilio — and that's a far more useful dataset for competitive sales.

If you sell a competing communications platform — whether that's Vonage, MessageBird, Bandwidth, Sinch, or an in-house CPaaS alternative — the most qualified pipeline you can build consists of companies already running on Twilio. They have budget allocated, they've validated the use case, and they're almost certainly evaluating alternatives as their contracts come up. You don't have to educate them on why communications infrastructure matters. You have to show them why switching makes sense.

The fastest way to build that list at scale is to use a tool like Stealery — you search a competitor (say, Twilio) and get a list of every company in the market known to be using it, filterable by company size, location, and hiring signals. What would take days of manual research across job boards, tech stack databases, and LinkedIn takes about 30 seconds.

Hiring signals are particularly useful in this context. A company posting a "Twilio Engineer" or "Twilio SMS Integration Developer" role is a confirmed active user — and if the role has been open for 60+ days, that often signals friction with the current setup. That's your trigger.

Practical prospecting signals from Twilio's office footprint

• EMEA accounts: Companies near Twilio's London and Dublin offices are more likely to have formal Twilio contracts with EMEA pricing structures — and are often evaluating GDPR-compliant alternatives.
• APAC accounts: Singapore-based or Southeast Asian companies using Twilio may face latency or local compliance issues that regional CPaaS providers can address directly.
• US mid-market: Twilio's Austin and New York sales offices cover high-density mid-market territory — companies in those geographies that are currently on Twilio are often at the stage where pricing pressure starts to bite.
