Huge milestone here. Firecrawl is making something agents want.

Postman is launching one of the most significant updates to our product - the AI Engineer.

In a recent batch talk, YC General Partner @t_blom broke down how to build a self-improving, AI-native company. He walks through how to create recursive, self-improving AI loops, and why founders who get this right will run companies that improve while they sleep. 00:00 — Companies Are Roman Legions 00:54 — Copilots Are the Wrong Mental Model 01:55 — Extract the Domain Knowledge 02:24 — The Recursive Self-Improving Loop 04:12 — The Holy Shit Moment at YC 05:50 — Self-Optimizing Product and Support Loops 06:29 — Burn Tokens, Not Headcount 07:23 — Middle Management Is Over 08:05 — Make Everything Legible to AI 09:40 — Regenerating the YC User Manual 11:19 — Software Is Ephemeral, Context Is Valuable 12:18 — Where Humans Still Matter

Huge congrats to @apurvas96 , @thetysonchen , and @getavoca! They've worked alongside home services operators to understand how the work actually gets done, then built what the trades needed. Today, 1,000+ businesses rely on Avoca to run their entire front office 24/7. @b_jishnu | Arjun Gandhi

Using Lean 4 to identify contradictions in laws. Very exciting work by Pramaana Labs pramaanalabs.ai. They have build a DSL called LegalLean to formalise US tax codes.

gumloop raised a $50m series b led by benchmark here's a video we had fun making about the journey back to work.

I have been blown away by the response from customers and developers about the new Postman launch! The new Postman is AI-native and it is reflecting in adoption. We just crossed more than 3 million developers now using AI and Agent Mode in Postman. Not just in terms of usage, the rate of new customers buying our paid plans has grown by more than 500% since launch. More than 2/3rds of our new customer cohorts are using AI features in Postman and the rate is only growing. While we are excited about this, we are working on many exciting capabilities: 1️⃣ Long-running and autonomous modes for agents in Postman 2️⃣ Bringing the right context across thousands of APIs and services and millions of datapoints for the agent to access. 3️⃣ Execution sandboxes for agents to do their work securely. 4️⃣ Simulations to allow agents to know the outside world without touching real APIs. All of this is possible with the work we have done over the last few months with v12 and the new Postman. If you missed the announcement, you can read it here: blog.postman.com/new-postman-is…

Not just a platform update; it's a blueprint for the agentic future. @getpostman is building the world's most comprehensive AI-native API platform, making APIs reliable, governed & agent-ready at scale for 40M+ developers. Proud to have backed this journey from day one. Congrats @a85 @sobtiankit , @abhijit_kane & the entire Postman team! @b_jishnu

“agent-native infrastructure teams can trust in production”. 🚀 @nexusvp

Huge study from Google. 👏 Builds a single leaderboard that checks how often chat models say true things in real use cases. Even the best model scores about 69% overall, so factuality is still far from solved. A large language model is a text generator that can sound confident while being wrong, so the paper treats factuality as a measurable skill. FACTS breaks that skill into 4 settings, answering questions about images, answering fact questions from memory, answering with web search, and answering using only a provided document. The authors use other language models as judges that mark answers correct only when they cover key facts and avoid contradictions. For image questions, humans write a checklist of essential facts, and the judge checks if the model covered them without making up wrong details. For the provided document setting, the judge also rejects vague replies that dodge the request, so models cannot score well by saying too little. The final FACTS score is the average of the 4 parts, with public and private tests so models cannot practice on the answers. ---- Paper Link – arxiv. org/abs/2512.10791 Paper Title: "The FACTS Leaderboard: A Comprehensive Benchmark for LLM Factuality"

🚀 Great partnerships are built over decades. We are incredibly proud to continue our 15-year journey with @shengjia_zhao and @smw355, the visionary team behind two category-defining companies: Cloud .com (acq. by Citrix) and @Rancher_Labs (acq. by @SUSE). Now, they're tackling their most ambitious challenge yet: solving the fragmentation and security risks of enterprise AI. Their new company, Obot AI (@acornlabs), is building the open-source Enterprise MCP Gateway—a single control plane for IT teams to safely adopt and manage AI assistants. We are thrilled to co-lead their $35M seed round. When a team with this calibre of execution sets out to build the standard foundation for enterprise AI, we are all-in. Congratulations to the entire Obot AI team! @b_jishnu Read more here: obot.ai/obot-ai-secure… #EnterpriseAI #OpenSource #MCP #Cybersecurity #AIInfrastructure

Congratulations, @tensorwave , on their $100M Series A! By fueling a massive AMD Instinct MI325X deployment, they're tackling the critical AI infrastructure bottleneck head-on. TensorWave isn't just scaling capacity; they're creating an entirely new category of enterprise AI infrastructure built for next-generation models and empowering developers across the ecosystem. Proud to partner with the TensorWave team! reuters.com/business/ai-in… @DarrickHorton | @jtatarchuk | @piotrstomasik | @b_jishnu | @Utkarshm42

The world is undergoing a fundamental transformation in software development through the power of AI and APIs. We aim to lead the way with support for building at the bleeding edge for AI. Is your organization keeping up the pace with best-in-class developer tooling or are you working with last decade's tech? Move fast or get left behind.

Model Context Protocol (MCP) has quickly emerged as the preferred way for agents to connect to the outside world. Excited to announce that MCP support is coming to Postman! What does this mean: 1. Work with MCP requests natively in Postman. 2. Support for SSE and stdio transports 3. Seamless, optimized UI to reduce friction in working with tools. Reply to this post for early access!
