Runpod Reaches $120M ARR Milestone, Originating from a Reddit Post

According to founders Zhen Lu and Pardeep Singh in an exclusive with TechCrunch, Runpod—an AI application hosting platform launched four years ago—has reached a $120 million annual revenue run rate.

Their startup journey vividly illustrates how building a solid product, combined with fortunate timing, can attract significant success.

The founders shared with TechCrunch how they bootstrapped their way past $1 million in revenue, secured a $20 million seed round after Dell Technologies Capital partner Radhika Malik discovered their Reddit posts, and gained Hugging Face co-founder Julien Chaumond as a key angel investor—after he reached out via support chat while using their product.

It all started in late 2021 when the two friends, who had worked together as corporate developers at Comcast, realized their side project was no longer enjoyable.

They had built specialized computer setups in their New Jersey basements to mine Ethereum. While they successfully generated some cryptocurrency, they admitted it wasn't enough to recoup their investment. Plus, mining was set to end following the highly anticipated network upgrade known as "The Merge."

On top of that, Lu said the process became "boring" after just a few months.

They estimated they had persuaded their wives to let them spend around $50,000 combined on the venture. Lu and Singh knew maintaining domestic harmony meant finding a productive use for those GPUs.

Having worked on machine learning projects professionally, the developers decided to convert their mining rigs into AI servers. This was before ChatGPT—even before DALL-E 2.

While repurposing the equipment, Lu recalled, "We saw how incredibly poor the software stack was for managing these GPUs." As developers, they identified a problem worth solving.

Runpod emerged, as Lu explained, "because we believed the actual experience of developing software on GPUs was completely subpar."

By early 2022, they were ready to launch their creation. Runpod is a platform for hosting AI applications, prioritizing speed, easily configurable hardware—including a serverless option that handles configuration automatically—and developer tools like APIs, command-line interfaces, and other integrations.

In 2021, they only offered a few integrations, such as support for Jupyter notebooks. Their next challenge was finding beta testers.

"As first-time founders, we had no experience with marketing or promotion," Lu remembered. "So I thought, let's just try posting on Reddit."

They posted in several AI-focused subreddits with a simple offer: free access to their AI servers in exchange for feedback. The strategy worked, attracting beta users who later became paying customers. Within nine months, they had left their jobs and reached $1 million in revenue.

Bootstrapping growth

Success brought new challenges. "Six months in, business users started saying, 'We want to run actual business applications on your platform, but we can't rely on servers located in people's basements,'" Lu explained.

The New Jersey-based founders hadn't considered VC funding initially. Instead, they formed revenue-sharing partnerships with data centers to expand capacity—a stressful process that required constant foresight.

"If we don't have enough GPUs, market and user sentiment shifts. When users don't see available capacity, they look elsewhere," Singh noted.

Meanwhile, their user base continued growing on Reddit and Discord, especially after ChatGPT's launch.

VCs were actively seeking investment opportunities. Malik discovered them through Reddit and made contact—their first VC meeting. Lu admitted he didn't know how to pitch to investors. "Radhika was incredibly helpful, even in that first conversation," he said. She explained how VCs evaluate opportunities and promised to stay in touch.

Meanwhile, Lu focused on building a self-sustaining business. "We operated without funding for nearly two years," he recalled. Consequently, Runpod never offered a free tier—every service had to cover its costs, even if profits were minimal. Unlike other AI cloud services that began as crypto mining operations, these founders avoided taking on debt.

By May 2024, as AI application development surged, their early decision to launch AI hosting for developers began paying off. Their platform had attracted 100,000 developers, and they closed a $20 million seed round co-led by Dell and Intel's venture arms, with participation from notable investors including Nat Friedman and Julien Chaumond.

They haven't raised additional capital since but are now preparing for their next round, confident that their business merits a strong Series A valuation.

Today, Runpod serves 500,000 developers—from individual users to Fortune 500 enterprise teams with annual spending in the millions.

Their cloud infrastructure spans 31 global regions and counts companies like Replit, Cursor, OpenAI, Perplexity, Wix, and Zillow among their users.

Competition remains intense. Developers can choose from major cloud providers (AWS, Microsoft, Google) plus industry-specific options like CoreWeave and Core Scientific.

However, Runpod positions itself differently—as a developer-centric platform. They believe coding will evolve rather than disappear, with programmers transitioning into AI agent creators and operators.

"Our vision is to become the foundation for this new generation of software developers," Lu stated.
