Intercom is headquartered at 55 2nd Street, San Francisco, CA 94105 — with its second operational hub in Dublin, Ireland, where the company was originally founded in 2011. Despite being best known as a San Francisco SaaS company, Intercom runs a genuinely distributed leadership structure across four countries, which matters if you're prospecting into the business or trying to understand how their teams are organised.
- Intercom HQ is at 55 2nd Street, San Francisco, CA 94105 — the commercial address for billing, legal, and enterprise sales contacts.
- Dublin, Ireland is Intercom's co-headquarters and engineering hub, reflecting its Irish founding roots.
- Intercom also maintains offices in London and Sydney, covering EMEA and APAC markets.
- The company operates on a hybrid model — a significant portion of the team works remotely, so physical office headcount is not the same as regional team size.
- If you're targeting companies that use Intercom as a customer support platform, office location is less useful than tech stack signals for building your list.
Where is Intercom headquartered?
Intercom's official headquarters is in San Francisco, California. The registered address is 55 2nd Street, 4th Floor, San Francisco, CA 94105. This is the address used for enterprise contracts, legal correspondence, and SEC-equivalent filings. The San Francisco office houses executive leadership including the CEO and go-to-market functions.
That said, Intercom is an unusual case among San Francisco SaaS companies: it was founded in Dublin in 2011 by Eoghan McCabe, Des Traynor, Ciaran Lee, and David Barrett — all Irish. The Dublin office has never been a satellite; it has always functioned as a co-equal hub for engineering, product, and R&D. When Intercom talks about its engineering culture, they're largely talking about Dublin.
For sales and GTM purposes, the San Francisco address is the primary point of contact. For engineering and product partnerships, Dublin is the more relevant location.
What are all of Intercom's office locations worldwide?
As of 2026, Intercom maintains four primary office locations across three continents:
- San Francisco, CA, USA — Global HQ. 55 2nd Street, 4th Floor, San Francisco, CA 94105. Houses executive leadership, sales, and US go-to-market.
- Dublin, Ireland — Co-headquarters and R&D hub. Located in the city centre. Engineering, product design, and a significant share of customer success.
- London, UK — EMEA sales and marketing office. Supports enterprise customers across the UK and continental Europe.
- Sydney, Australia — APAC office. Covers Australia, New Zealand, and broader Asia-Pacific commercial operations.
Intercom does not currently operate offices in continental Europe (outside Ireland), Southeast Asia, or Latin America, though it serves customers in all those regions through remote teams and channel partners.
A note on Intercom's remote workforce
Following the 2020–2022 period, Intercom — like most SaaS companies — shifted to a hybrid model. A meaningful share of its roughly 900–1,000 employees (as of 2025 headcount estimates) work remotely and are not based near any of the four offices. Regional team size cannot be reliably inferred from office location alone.
What is Intercom's Dublin office address?
Intercom's Dublin office is located at Stephen Court, 18-21 St Stephen's Green, Dublin 2, D02 HH24, Ireland. This is one of the most prominent business addresses in central Dublin, shared with other technology companies that have established Irish operations.
Dublin holds special significance for Intercom beyond geography. The company's founders are Irish, and Intercom was incorporated in Ireland before expanding to the US. The Dublin office has historically housed a large share of the engineering and product teams, and many of Intercom's senior technical leaders are based there.
For European enterprise prospects and customers, the Dublin office is often the relevant commercial contact point, particularly for data processing agreements under GDPR, where Intercom Ireland Limited acts as the data processor entity.
Why does Intercom have both a San Francisco and Dublin headquarters?
Intercom's dual-headquarters structure reflects its founding story more than a deliberate international expansion strategy. The company was built by four Irish engineers in Dublin, raised its first significant funding from US investors, and established a San Francisco presence to be closer to the US venture ecosystem and enterprise customer base. Both locations grew organically into genuine centres of gravity rather than one being a satellite of the other.
This structure is increasingly common among companies founded in strong tech ecosystems outside the US — particularly Ireland, Israel, and the UK — that want access to US capital and enterprise customers without abandoning their founding team and engineering culture.
"We've always been a company that believed location shouldn't limit talent. Dublin gives us access to some of the best engineering talent in Europe, while San Francisco keeps us close to the enterprise customers we serve at scale."
— Eoghan McCabe, Co-founder & CEO, Intercom (as quoted in The Irish Times, 2019)
From a sales prospecting perspective, this matters because Intercom's buying decisions — particularly for enterprise partnerships and integrations — can involve stakeholders in multiple time zones. Deals may start with a US-based champion and require sign-off from technical or legal teams in Dublin.
How big is Intercom and how many employees does it have?
Intercom is a private company and does not publish official headcount figures. Based on LinkedIn data and public reporting, Intercom employed approximately 900–1,100 people as of late 2025, down from a peak of around 1,300 during the 2021–2022 growth period following several rounds of post-COVID rightsizing that affected many SaaS companies.
The company has raised over $240 million in venture funding across multiple rounds, with investors including Bessemer Venture Partners, Index Ventures, and Social Capital. It has been consistently valued above $1 billion, placing it firmly in unicorn territory, though it has not pursued an IPO as of mid-2026.
According to Statista's tracking of Intercom's workforce, the company's headcount grew significantly between 2019 and 2022 before stabilising. Current employee distribution skews toward engineering (Dublin) and sales (San Francisco and London).
Who uses Intercom, and why does this matter for B2B sales?
Intercom is one of the most widely deployed customer messaging platforms in B2B SaaS. According to BuiltWith's technology tracking data, Intercom is installed on over 400,000 websites globally, with the heaviest concentration among Series A–C SaaS companies that have 20–500 employees and a self-serve or product-led growth motion.
If you sell a competing customer support, live chat, or customer success platform — products like Zendesk, Freshdesk, HubSpot Service Hub, Drift, or Help Scout — then Intercom's installed base is your most qualified prospect list. These companies have already demonstrated that they will pay for this category of software. The only question is whether your product solves a problem Intercom doesn't, or solves it better.
The fastest way to build that list at scale is to use a tool like Stealery — you type in "Intercom" and get a filtered list of every company running it, segmented by employee count, geography, and growth signals like active hiring. What would take days of manual research through job boards and tech stack tools takes about 30 seconds.
What types of companies use Intercom most heavily?
Based on public install data and customer case studies, Intercom adoption is concentrated in:
- B2B SaaS companies with a self-serve onboarding flow (where in-app messaging directly drives activation)
- E-commerce and DTC brands that run high-volume customer support
- Financial services and fintech companies that need compliant, auditable customer communication
- Companies using product-led growth (PLG) models, where Intercom's in-product messaging is core to the conversion funnel
If your ICP overlaps with any of these segments, an Intercom-filtered prospect list is worth running before your next outbound sequence.
What is Intercom's headquarters contact information?
Intercom does not publish a general inbound phone number for its San Francisco headquarters. Enterprise sales inquiries are handled through the website at intercom.com/contact. For press and media inquiries, the contact is press@intercom.com. For legal and compliance matters — including GDPR data requests — the relevant entity is Intercom R&D Unlimited Company, registered in Ireland.
