Celebrating startups innovation and connection at re:Invent 2025

Startups, experts, and innovators from across the world gathered in Las Vegas earlier this month for the 14th annual AWS re:Invent. Through workshops, keynotes, demos, and discussions, the global cloud community built connections, made discoveries, and shared successes.

Dr. Swami Sivasubramanian, Vice President of Agentic AI at AWS, invited attendees to reflect on such successes, opening his keynote by asking his audience to look back in time and recall “that exhilarating feeling that you just unlocked a whole new world of possibilities.” Today, he continued “builders around the world are experiencing that same sense of freedom with the help of AI agents.” Jason Bennett, Vice President, Worldwide Startups and Venture Capital at AWS, echoed Sivasubramanian’s sentiment. Speaking at re:Invent, he described how agents “are set to transform the way that we both work and live and the impact it will have for many of our companies,” and shared his excitement “for how we’re going to engage with some of our customers going forward.”

The development of agentic AI is broadening the scope of who can create and how, helping to level the playing field for the startup community. Describing what we want to build through natural language and leveraging AI agents to achieve this is making innovators of us all, providing “the freedom to build without limits” and “accelerating how quickly you can go from idea to impact,” said Sivasubramanian.

 

Conversation is critical but re:Invent also demonstrated innovation in action, showcasing new technologies that enable creators and developers to think bigger and build better. AWS CEO Matt Garman revealed a number of key announcements when he addressed re:Invent’s 60,000+ attendees (plus millions watching online). Before talking technology, Garman opened by thanking the people behind the technology and included a shout-out to one community in particular: “I have a special affinity for our startup customers,” he said. “More unicorn startups have been built on AWS than anywhere else, and it isn't even close.” 85 percent of the Forbes 2025 AI 50 and 85 percent of the CNBC Disruptor 50 are all running on AWS, he continued.

To support these pioneers, Garman unveiled what AWS has been working on, with new releases promising to help more builders develop their ideas and realize returns faster and easier. “Today is a big leap forward in the journey unlocking the value of AI,” he said, with AWS “bringing you powerful innovations at every single layer of the stack.” These innovations included the launch of AWS AI Factories, enabling customers to deploy dedicated AI infrastructure for AWS in their own data centers. Plus, the general availability of Amazon S3 Vectors, allowing users to store trillions of vectors in a single S3 bucket and reduce the cost of storing and querying them by 90 percent. Deap Ubhi, Global Director of Technology for Startups at AWS described this as “a huge enabler for agentic and gen AI workloads in AWS.” 

Enhancements of existing solutions were also announced, including the expansion of the Amazon Nova portfolio with the addition of four new models. Garman also offered “a sneak peek as to what's coming around the corner,” with an update on the development of Trainium 4, which promises “six times the FP4 compute performance, four times more memory bandwidth, and two times more high memory bandwidth capacity to support the very largest models that you have in the world.”

 

This is a mere snapshot of the significant breadth of new and enhanced solutions unveiled over the course of week; check out the Top announcements of AWS re:Invent 2025. The event is not just a cornerstone of the tech calendar, it's first and foremost about people: the builders, creators, founders, and pioneers. As Garman said during his keynote, “At Amazon, everything starts with the customer.” It was a celebration of the millions of businesses running every imaginable use case, across every single industry and vertical, which have “transformed industries like financial services, healthcare, media entertainment, telecommunication, even government agencies all around the world,” he continued.

These include startups like data security specialist, DataMasque, which returned to AWS re:Invent this year. “It gets bigger and brighter every time,” said CEO and Co-founder, Grant de Leeuw. Speaking at the event, he shared his excitement to be working with government, financial services, and healthcare, helping these regulated organizations “leverage their customer data for AI and ML use cases safely and securely.” re:Invent offered the ideal opportunity to connect with key stakeholders in these sectors, as well as creating an environment which fostered peer-to-peer learning.  Shubhii Agarawal, Co-founder of Locobuzz, attended the event in order to “learn what other startups are doing in the same direction.” She continued, “There is a lot of work in agentic AI that is happening in both AWS as well as at Locobuzz, so learning from the entire ecosystem, meeting with some interesting people and of course my friends, that’s what I’m here for.”

Bob West, Data and AI Security Officer at Cyera also prioritized meeting with prospects and peers, making the most of the “spark environment” at re:Invent. “Thanks to you we’re paired up with a number of good meetings and it’s just tremendously helpful,” he said.

The combination of technical innovation and technical innovators similarly benefitted Gabriel Musso, Chief Scientific Officer at Lunai Bioworks, who was attending re:Invent for the first time this year. The event allowed Musso to experience “what’s on the cutting edge; seeing the newest technologies, what we include in our own work, and how we can leverage them.” Crucially, it’s also provided a “wonderful opportunity” to “plug in and see all the other startups, to compare stories, to talk about what we’ve done and what they’ve done, and to try to forge new partnerships.”
