Nutanix and ThoughtSpot Founder Ajeet Singh Launches AI Marketing Startup Different With a $48 Million Seed Round

Ajeet Singh, one of the most successful Indian-origin founders in Silicon Valley, has launched his third company, betting that artificial intelligence can do much of the work of a modern marketing department.

Singh, who co-founded cloud computing company Nutanix and founded analytics firm ThoughtSpot, has unveiled Different, an AI marketing startup that emerged from stealth with $48 million (about ₹453 crore) in seed funding, Inc42 reported on Thursday, October 22. The round was led by General Catalyst, with participation from Lightspeed Venture Partners.

The size of the round is notable. A $48 million seed round is unusually large, even by Silicon Valley standards, and reflects both investor confidence in Singh's track record and the intense interest in AI applications for business.

What Different does

In a LinkedIn post, Singh described the company's purpose: "Different is an AI marketing system that runs demand generation end-to-end for lean B2B marketing teams."

The platform plans, creates, executes and scales personalised content across channels, based on a company's business context, strategy, audience and other parameters set by users. It learns from campaign results and adjusts to improve performance.

Different is targeting problems that many business-to-business companies face: the difficulty of hiring specialised marketing talent, the cost and complexity of working with multiple outside agencies, and the challenge of managing a scattered set of marketing software tools. By automating much of this work, the company aims to let small marketing teams achieve the output of much larger ones.

Before its public launch, Different tested its service with early corporate customers, including software companies Descope and Motif.

The founding team

Singh's co-founders are Abhishek Pani, a former executive at work management company Asana, and Abhinav Yajurvedi, previously the chief technology and product officer at PharmEasy. The company has teams in San Francisco and Bengaluru, according to its website, a structure common among Indian-origin founders building global software companies.

A founder with two big wins

Singh's career is one of the most celebrated among Indian technology entrepreneurs abroad. An alumnus of IIT Kanpur and IIM Calcutta, he worked at Oracle, Honeywell and PwC before co-founding Nutanix in 2009. Nutanix, which pioneered hyperconverged infrastructure that combines computing and storage, listed on the Nasdaq in 2016 and became one of the leading enterprise cloud companies.

Singh stepped down from Nutanix in 2012 and launched ThoughtSpot the same year. ThoughtSpot, which offers AI-powered analytics that let business users search their data in natural language, has raised more than $670 million and was last valued at nearly $4.5 billion.

Different is his third venture, and it moves him from data infrastructure and analytics into marketing applications.

The AI marketing opportunity

Marketing is one of the business functions most directly affected by generative AI. AI models can now write copy, create images and video, personalise messages for different audiences, and analyse campaign performance. Companies across the marketing technology industry are racing to incorporate these capabilities.

The shift is particularly significant for B2B marketing, where companies need to produce large volumes of content, from blog posts and white papers to emails and social media updates, to generate leads. Many smaller companies struggle to maintain consistent, high-quality output.

“Different is an AI marketing system that runs demand generation end-to-end for lean B2B marketing teams.”
— Ajeet Singh, Co-founder, Different

Different's pitch goes beyond content generation. By running "demand generation end-to-end," it aims to act as an autonomous marketing system that handles planning, execution and optimisation, rather than a tool that assists human marketers with individual tasks. That fits a broader trend towards AI agents that can carry out multi-step work with limited supervision.

A crowded and fast-moving market

The AI marketing space is highly competitive. Large software companies such as Salesforce, Adobe and HubSpot are building AI into their marketing platforms, while numerous startups offer AI tools for content creation, advertising and campaign management. Salesforce's agreement this month to acquire customer engagement platform Braze for $5.66 billion underlined the strategic importance of marketing technology.

Different will need to show that its system delivers measurably better results than combining existing tools with human teams. Customers will want evidence that AI-generated campaigns maintain brand quality and produce real pipeline and revenue.

Why it matters for India

Different's structure, with teams in both San Francisco and Bengaluru, reflects a common model among Indian-origin founders who build global software products with engineering talent in India. Nutanix and ThoughtSpot both developed significant operations in India, and Singh's track record has helped shape the ecosystem of enterprise software talent in the country.

The launch also highlights the growing role of India-linked founders in the global AI industry. Indian engineers and entrepreneurs are prominent in AI startups in the United States, and many are building companies that combine Silicon Valley market access with Indian development capabilities.

The Indian-origin founder network

Singh is part of a generation of Indian-origin founders who have built major technology companies in the United States, a group that includes the founders of companies such as Sun Microsystems, Hotmail, Juniper Networks and many enterprise software firms. Their success has created a network of experienced entrepreneurs, executives and investors who support new ventures.

That network has become a significant source of capital and mentorship for Indian startups as well. Successful founders often invest in or advise companies in India, and some, like Singh, build companies with significant teams in the country. The flow of talent and ideas between Silicon Valley and Bengaluru has been one of the defining features of India's technology industry.

Why seed rounds are getting bigger

Different's $48 million seed round reflects a broader trend of unusually large early rounds for AI startups led by proven founders. Investors are willing to commit significant capital early to secure stakes in companies they believe could become category leaders, and AI startups often need substantial resources for computing, talent and go-to-market efforts. Experienced founders with track records of building large companies command particular premiums.

What comes next

With $48 million in seed capital, Different has ample resources to build its product and acquire customers. Its early progress will be closely watched as a test of whether AI agents can take over core business functions such as marketing.

For Singh, the challenge is to repeat his earlier successes in a new and crowded market. Given his record, investors are clearly willing to bet that he can. Different's progress will be followed closely by founders and investors in both Silicon Valley and Bengaluru.
