The company that keeps asking the same question - how do you keep people engaged? - and keeps changing its answer.
Somewhere right now, a caller dials an auto dealership, a government office, or a university help line, and a voice picks up. It is calm, it is fast, and it does not need a coffee break. It is built by Web Spiders. The company that wrote that voice has been in business since the year the dot-com bubble burst, which makes it older than most of the AI startups currently promising to replace it.
Web Spiders - WS Group on the paperwork - is an enterprise AI and digital engineering firm. It builds voice agents, chatbots, event platforms and data products for Fortune 2000 enterprises and government agencies. Roughly 290 people, spread across the United States, United Kingdom, Singapore and India. The pitch fits on a business card: the AI company for customer experience. The history does not fit so neatly.
In 2000, "user engagement" was not yet a metric on anyone's dashboard. Most businesses thought a website was a brochure that happened to glow. Web Spiders disagreed. The interesting problem, they decided, was not putting a company online - it was getting anyone to stick around once they arrived.
That bet looks obvious now. It was not obvious then. Attention is the one resource that has only gotten scarcer over 25 years, and every wave of technology since - mobile, social, conversational AI - has been, underneath, a new front in the same war for it. Web Spiders kept following engagement wherever it migrated. When attention moved to phones, they built rich mobile apps. When it moved to conversations, they built bots. When it moved to voice, they built SpiderX.
Siddharth Jhunjhunwala started Web Spiders while he was still in college, in Kolkata, with two computers and the unfashionable conviction that a services company from India could build products the world would pay for. He had run a software company before this one. His brother Vijay Jhunjhunwala came in as co-founder and now serves as CFO and Chairman. There is no venture-capital origin myth here, no Series A to celebrate - the company grew the slow way, on revenue.
The slow way has its advantages. Twenty-five years of compounding turned two computers into a co-located headquarters in Singapore, a US base in San Jose, and offices in the UK and India. Bootstrapping also bought them something money usually cannot: the freedom to reinvent the business three times without asking a board for permission.
Founded in Kolkata with two computers. The web is the frontier; engagement is the obsession.
Builds an enterprise content management and digital services practice. Becomes a Drupal-Acquia and Microsoft partner.
Pivots into enterprise mobility - rich mobile apps, event technology (e2m.live) and marketing tech. Expands to the UK, Singapore and the US.
Adds AI-led chatbots, data labeling and the Gecko AI video interview bot. Engagement goes conversational.
Repositions around SpiderX AI - voice agents, private enterprise LLMs and data products. Wins Best CX Team of the Year and an Agentic AI Voice Analytics award.
Today the work runs on a small menagerie of products, which is fitting for a company named after an animal. SpiderX is the headline act: generative voice AI agents for websites, apps and actual phone lines, sold pre-built for the least futuristic-looking places imaginable - government offices, hotels, auto dealerships, university admissions. Underneath it sits a private LLM and a data-ingestion stack, so the enterprise's data stays the enterprise's.
Generative voice agents for web, apps and phone lines, with a private LLM and data-ingestion stack to build enterprise data products. Deployed in weeks, not months.
Enterprise event and engagement platform for in-person, hybrid and virtual conferences, webinars and experiences.
AI-based video interview and screening bot that handles first-round candidate conversations.
Developer platform exposing Voice AI APIs and SDKs for teams who would rather build than buy.
Around the products is the services arm that paid for all of it: product engineering, AI-first web portals, data engineering, conversational analytics, and - quietly important in the AI era - data labeling and annotation. The unglamorous work of teaching machines what they are looking at.
Skeptics ask for evidence, and Web Spiders has a client list that reads like a stock index. Mitsubishi Motors. Accenture. Amazon. Ogilvy. Cognizant. The American Society of Mechanical Engineers. Johns Hopkins University. Add Fortune 2000 enterprises and government agencies across education, law, finance, retail and insurance, and you have north of 500 clients served.
Then there are the partner badges, the kind that only get handed out after audits: Microsoft Gold Certified Partner, Google Cloud Partner, AWS Technology Partner, Adobe Solution Partner, Acquia-Drupal Partner, Zoom ISV Partner. Not glamorous. Very load-bearing.
And the trophies are recent, not vintage: SpiderX AI took Best Customer Experience Team of the Year at the 2025 Smart CX Summit Awards, and an Agentic AI Voice Analytics award at Future of Finance 2025. A 25-year-old company is not supposed to be winning the AI prizes. This one is.
Strip away the product names and the mission is plain: combine AI, data and design so that every customer interaction turns into a growth opportunity. Or, less politely - stop wasting people's attention, because they will not give it back. The vision points one step further out, toward a voice-first, AI-driven era where the conversation, not the click, is the interface.
It is a tidy theory. The honest version is messier, because none of this is settled. Enterprises are nervous about handing their data and their customers' voices to a model. Web Spiders' answer - private LLMs, data that never leaves the building - is a bet that trust, not raw capability, becomes the constraint that matters. They may be right. They have been right about engagement for 25 years, which is a longer track record than most of the field has been alive.
Return to that caller from the start - the one dialing a dealership or a government line. For most of the last century, that call meant a wait, a queue, a recording that apologized for unusually high call volume. The interaction was something to survive, not something that earned its keep.
Web Spiders is trying to change the texture of that moment. Not by replacing people with a gimmick, but by handling the dull half of the conversation so the humans can field the hard half. Whether voice AI delivers on that or just relocates the frustration is the open question of the decade. What is not in question is that a company started with two computers in Kolkata has earned a seat at that table - by staying obsessed with one problem long enough to watch the technology catch up to it.
The voice that picks up has gotten smarter. The question behind it - how do you keep someone on the line? - is exactly the one Web Spiders has been answering since 2000.
