Merge Gateway enables the best AI teams to attribute every single dollar as granularly as possible. That’s why we’re excited about supporting the launch of AUDR from the @chargebee team, an open specification for recording agent usage and costs. A much needed standard for the space. An AUDR adapter for the Merge Gateway will be out soon. Check it out here: openaudr.dev/

The economics under most agent products are still hard to see. Teams ship an AI workflow without a firm cost-per-outcome understanding, reconcile the model bill against an average, and then quarter end arrives. A feature priced one way turns out far more costly to serve than expected. Why? A single run extends across a harness, one or more routers, and the tools it calls, and each one sees only its own slice. The harness knows the customer and features. The router knows the tokens. A tool can hold a sandbox open for four minutes or wrap a paid API, but those costs never reach the router. Every layer can be fully instrumented, and we’ll still have no single record of what the run actually cost, end to end. Today, we're proud to introduce AUDR (Agent Usage Detail Record), an open standard for that agent run cost record. The standard borrows from the telecom industry's Call Detail Record: meter usage now, price it later. Three rules make that possible: one run ID across every layer, one authoritative source per field, and strict merging with no silent overwrites. We're building AUDR alongside some of the best teams in the ecosystem, as spec reviewers, early adopters, or advocates, including @merge_api, @mastra, and @tinyhumansai, among others. For developers to get started easily, the spec plan includes adapters for key platforms and frameworks, including @nvidia NeMo Relay, Merge Gateway, Mastra, @vercel eve, @LangChain, @LiteLLM, and @OpenRouter Granular cost instrumentation is becoming foundational infrastructure for anyone building or monetizing agents. We think it should be open, neutral, and community owned. Read the spec, write an adapter, and help us improve it: openaudr.dev/

A good test for custom/domain-specific harnesses is that their agentic output should get better with more capable models in the mix. Our team has been shaping the context, data, and environment(s) for ours with great deliberation. More here, in case you’re looking to compare notes/learn more: docs.google.com/document/d/1…
Either you die a system of record or you live long enough to become a domain-specific harness

Beelieve is back on the road in four more cities this fall. Beelieve 2026 kicked off with incredible energy in San Francisco and London earlier this year, bringing together founders and leaders in product, finance, and ops for candid conversations on the front lines of modern revenue. Together, we dove deep into what's truly reshaping our industry: transforming pricing from an afterthought into a core product driver, navigating a new landscape where agents handle purchasing autonomously, and building robust revenue recognition practices that hold up under scrutiny—far beyond the usual end-of-quarter scramble. Building on the incredible momentum from SF and London, the journey continues in: 📍 Sydney on September 15th 📍 New York on September 22nd 📍 Berlin on October 6th 📍 Paris on October 14th What makes these rooms special is the dynamic blend of perspectives—where visionary AI-native founders collaborate alongside seasoned SaaS veterans to navigate today's shifting landscape. Every company, no matter its size, scale, or stage, is navigating the strategy and operations required to do business in the AI era. At Chargebee, we're proud to host these conversations as we build the core infrastructure powering that future. Snag your spot and catch us in your city here: events.chargebee.com/ #Chargebee #Beelieve2026

India’s IT services industry is worth $264 billion, decades-old, outsourced to, giants in the arena. @realfastai is upending it with an ai-native approach. @ponnappa, co-founder of realfast, ex-Gojek, shared that they hit $3M in revenue just in the first half of 2026, with margins close to 60%, and a very lean but mighty team. We dig into the how, Sidu's vision, pricing services at a neofirm, thoughts on moat, building a team, and more. My favorite was the story of Exo, what Sidu calls their alpha. How it is the result of a new kind of productization, why they don't sell it, and what it enables internally. Read the full chat here: pmfevals.substack.com/p/the-… Thanks to Sidu for taking the time to chat!

Good cause. So I am going to be shameless to share it. I got an opportunity to witness and be part of something meaningful today. Some of these organizations are doing genuinely important work could use more support. Chargebee, along with Madras Round Table-1 (MRT-1) has been working towards contributing to a school infrastructure - specifically, a government school in Pallavaram, Chennai. I had a chance to speak with the headmaster to understand the constraints these schools operate under. Last year, we helped build two floors of the school - 8 new classrooms. Today, the school has 1,400 enrolled students. These are kids who need the system to work for them, and this school is trying hard to make it do exactly that. What's already happening here in the last few years is remarkable. HCL has built a center of excellence on campus with a state-of-the-art science lab. They continue to maintain it too. It's become a source of pride for the school, and more than 1,000 students from neighbouring government schools visit it regularly. By all accounts, it's one of the best science facilities in the area, visually demonstrating science fundamentals. Hyundai is now building another school wing, including an auditorium. These are facilities that private school students take for granted and government school students deserve too. In five years, the school has improved a lot with the help of public-private partnerships like these. Another challenge is that better infrastructure has driven enrollment, and a strong open-door policy means no student from the neighborhood is turned away. That's the right thing to do and it comes with real challenges. The school currently has 29 classrooms. Last year, they needed 33. Today, the need is 35. Some classes now have 85–90 students. They could use more support. Why I'm sharing this? Organizations like MRT-1 have been exceptional at identifying these opportunities through fundraising and community services, and working with reliable contractors who deliver projects within a shorter turnaround time - responsibly and without waste. Also, MRT-1 itself is a run by entrepreneurs and this is one of the many social impact projects taken up by the members. I'm sharing this so more entrepreneurs and companies with CSR funds become aware of schools like this one, and the organizations that support them. Infrastructure like this changes the everyday reality for thousands of students. Many of you do this work quietly. We'd love that too. If sharing this story results in one more school getting the timely help it needs then it's worth being shameless to spread it. Reply if you want the contacts and someone from our team (@chargebee) can share them with you, to explore this on your own. Thank you! 🙏

Many companies treat pricing as something that happens after the product is built. @MiroHQ and Fin treat it as part of the product itself. Here's what they shared at Beelieve London. chargebee.com/blog/what-miro… #Chargebee #Beelieve2026

We built an admin browser. Every engineer uses it to debug. New hires also learn to ship here. Now we're doing the same with "backstage" for agents. It's the tooling no customer sees. But it's the scaffolding that is necessary to move fast with confidence.

Every day someone decorates this statue in our building. Different flowers. Different arrangements each time. I don’t know who. But you notice the intention in their choice of flowers and the design they seem to choose everyday.

like money? ✅ like agents? ✅ like meetups? ✅ luma link: luma.com/5nqllmul?tk=KaEUsU
I can wait on AGI, but can our agents get some money awareness... ASAP? 💸 Most agents are financially reckless by default. Add any complexity and you could one-shot your entire token budget. 🤯 Excited to co-host an evening in SF with @mastra_ai where we dig into the principles behind scaling radically efficient agents with some of the best minds in the arena. On the agenda: → a workshop with @bookercodes 🛠️ → a lightning talk ft. @swyx ⚡ → a fireside chat with @NotionHQ's @sarahmsachs and our co-founder Rajaraman Santhanam 🔥 Followed by food, drinks, and conversations. April 15 | Fort Mason | 5 PM | 100 spots RSVP → luma.com/5nqllmul
