SaaS is dead. Long live SaaS. These are @virioai's hypotheses for how AI-native services must look act to win in 2026

Today Reactor is coming out of stealth. We’ve raised $59M in Seed and Series A funding, led by @lightspeedvp, with participation from @AmplifyPartners, @wndrco, @Sky9Capital, and @FPVventures. Reactor is the platform for building in the World Model era: the infrastructure that lets developers build with them at global scale for the first time. Stream from a frontier World Model to your app, in real time, all in under 10 lines of code. World Models represent the next major shift in AI: pixels, audio and actions are generated on the fly, in real-time, in response to user inputs, and to the environment. Every time computing has made a shift from passive to interactive, entire industries appeared that didn't exist before. We're standing in front of such moment again. Over the last 6 months, we’ve assembled an all-star team with alumni from Apple, Meta, Google, Luma AI, Netflix, and Replicate. We're already partnering with some of the biggest names and labs in the world, and hundreds of developers are already building on Reactor. The World Model era starts now.

building great product is a lot like being a magician one has to dance around the limits of expectation and heighten experiences for the viewer such that it feels like magic

I met Sean at a GC event a few months ago, then my co added $1M ARR in 30 days
Yesterday I interviewed @SeanZCai about AI data. This is essentially a guide for founders on how to sell data and RL envs to AI labs. "I've never seen a data contract get turned down by a top lab, if it's good quality data, for budget reasons." 00:00 What areas of data are underserved? 02:10 For bio data, is it real-world or purely digital? 04:21 For cyber data, which subsets are most underserved? 05:50 What is the sales process like? 07:04 Why would a lab not renew or increase their purchase volume? 10:13 When a researcher is exploring a new direction, what's the first step? 11:35 In robotics data, what do you view as underserved? 13:12 What does the initial data delivery look like, what format? 13:53 Do labs have more sophisticated internal setups for running environments? 14:32 Are the non-frontier labs buying off-the-shelf data from Anthropic / OpenAI vendors? 16:11 Do Anthropic data vendors put expiry timeframes on the exclusivity? 16:42 Are purchase decisions researcher-led? 17:41 Decagon, Sierra, Ramp: what kinds of data are they buying? 19:06 Long-term, when do labs still need to buy external data vs train on user traces? 21:15 Will end-vendor benchmarks shift to performance per dollar? 22:04 How many labs are spending at the 1B /yr data level? 23:53 Delta between Anthropic's stated $1B and your 10-20B/lab number? 26:05 What makes inference providers / neoclouds a good fit to acquire RL env cos?

working ai-native means planning for 99% of the time and then one-shotting the whole thing with your god-tier plan in the last 1%

sydney sweeney reveals in an interview that she is churning off modal and switching her compute provider to newbird AI (formerly allbirds) “modal has been my go-to for a while but the pricing just doesn’t make sense anymore and cold starts have been killing me. When I heard about the allbirds pivot, I was bullish. I’m expecting the pricing to be aggressive, the infra clean, and honestly modal has been coasting. newbird AI is going to sweep”

Hello. We recently hired Jude Law to be the face of our brand. So, moving forward, we would prefer that you associate him with precise drafting, seamless collaboration and the ability to analyze thousands of legal documents simultaneously. In line with his contract, something like, “Oh, wow, he makes me think of that collaborative AI platform for exceptional lawyers!” would be an ideal ask. But we don’t want to push it.

funnily enough, even meeting notetakers were 1. one of the earliest mainstream use cases for AI software and 2. got memed to death they'll probably be one of the only durable use cases for AI software bc only software that supports/enhances human-to-human interactions will stay

Interesting how over time, OAI’s human-agent thesis has become less like n8n/zapier (OAI agent builder) and more like Sierra (OAI Frontier) Agent builder assumed more upskilling of the everyman working in the weeds with agentic workflows Frontier assumes more upfront cost of a few very technical implementers and then meeting the end users where they’re at

The hard reality is that this is just going to be a mental shift humans need to adapt to as the nature of knowledge work moves up the abstraction ladder Pros: everyone becomes more high-agency and better at making decisions quickly Cons: attention spans will def not improve
New Harvard Business Review research reveals that excessive interaction with AI is causing a specific type of mental exhaustion ( or AI brain fry), which is particularly hitting high performers who use the tech to push past their normal limits. A survey of 1,500 workers reveals that AI is intensifying workloads rather than reducing them, leading to a new form of mental fog. While AI is generally supposed to lighten the load, it often forces users into constant task-switching and intense oversight that actually clutters the mind. This mental static happens because you aren't just doing your job anymore; you are managing multiple digital agents and double-checking their work, which creates a massive cognitive burden. The study found that 14% of full-time workers already feel this fog, with the highest impact seen in technical fields like software development, IT, and finance. High oversight is the biggest culprit, as supervising multiple AI outputs leads to a 12% increase in mental fatigue and a 33% jump in decision fatigue. This isn't just a personal health issue; it directly impacts companies because exhausted employees are 10% more likely to quit. For massive firms worth many B, this decision paralysis can lead to millions of dollars in lost value due to poor choices or total inaction. Essentially, we are working harder to manage our tools than we are to solve the actual problems they were meant to fix. --- hbr .org/2026/03/when-using-ai-leads-to-brain-fry

Our engineers are the youngest in the company and our salespeople are the most senior career people in the company ✔️
never been a better time to build a tech company with 20 year old engineers and 40 year old salespeople very spooky time to build a tech company with 40 year old engineers and 20 year old salespeople
