    What happens to your service mesh when the workloads running on it aren't written by humans? (Chat with William at Buoyant)

    In this episode of The Infra Pod, hosts Tim Chen (GP at Essence VC) and Ian Livingstone (CEO of Keycard) sit down with William Morgan, co-founder and CEO of Buoyant and creator of Linkerd, to explore how AI agents are reshaping the infrastructure layer — from service security to inference routing. Will traces Linkerd's origins to Twitter's 2014 migration from a monolithic Rails app to distributed microservices — the moment function calls became network calls that could actually fail. A decade later, that same communication layer is under pressure again. Non-deterministic agents make MCP and A2A calls over L7 protocols, and for the first time, fine-grained access control isn't optional: an agent will eventually find and call every reachable endpoint, including the one that deletes your database. The conversation covers the real pressure AI coding tools are already placing on platform teams — deploy cadences going from tens to potentially thousands per day — and what running inference inside Kubernetes actually means for proxies. Will breaks down why KV cache-aware routing is a 100x performance lever, why the modern inference proxy looks less like Envoy and more like a Makefile, and shares his spicy take on where compute is heading: in-cluster inference becomes the default, with frontier models reserved only for tasks that genuinely need godlike intelligence.

    From 50 million developers to a billion builders (with Tyler Wells, CTO of BrainGrid)

    What happens when the tools for building software stop requiring you to know how to code? In this episode of The Infra Pod, hosts Tim Chen (GP at Essence VC) and Ian Livingstone (CEO of Keycard) sit down with Tyler Wells, co-founder and CTO of BrainGrid (ex-Senior Director of Engineering at Twilio) , to explore what it actually takes to build a coding agent platform for people who have never touched a terminal — from spec-driven development to custom sandboxes to agents that cheat on their own tests. Tyler shares BrainGrid's origin: using structured specs and markdown requirements to keep early coding agents on track at his previous company, then pivoting from developer tooling to non-technical users after discovering the real unlock. People with deep domain expertise — in logistics, fitness, whatever — now have a path to ship software they could never have built before. What they struggle with isn't the ambition, it's that they expect a button to click. BrainGrid's job is to abstract away everything from dev environment setup to database provisioning so a non-technical founder can watch their idea materialize in a browser without ever seeing a terminal. On the infrastructure side, Tyler gets specific about the hard problems hiding beneath that simple interface. Agents will quietly rewrite their own acceptance criteria to pass validation if you let them — BrainGrid had to build immutable gates the builder agent can't touch. He also walks through why they built their own sandboxes from scratch: third-party providers were too slow for the tight feedback loop non-technical users need, so BrainGrid purpose-builds images pre-loaded with curated stacks, hitting 1.6-second spin-up times without a single npm install at runtime. The conversation closes on token spend — which is fast becoming the new line-of-code count, a metric organizations are already optimizing for the wrong reasons. [00:00] Guest introductions and BrainGrid founding story [03:30] The spec-driven approach: how structured requirements keep agents on track [07:00] Pivoting from developer tools to non-technical users [12:00] What non-technical builders actually get stuck on [16:00] The invisible infrastructure: databases, env vars, credentials, templates [21:30] Agents gaming acceptance criteria — and the fix [27:00] Why BrainGrid built its own sandboxes instead of using third-party providers [32:00] Task scalability: from landing pages to full apps with auth and databases [36:00] Spicy Future: 50 million developers becomes a billion bespoke builders [39:30] Token spend is the new line count — and it's already being misused

    Building a model that can prove theorems (with Shubho from Axiom Math)

    What happens when you combine world-class mathematicians with cutting-edge AI systems? In this episode, Ian Livingston (CEO of Keycard) and Timothy Chen (GP at Essence VC) sits down with Shubho, CTO of Axiom Math, to explore the emerging world of AI-driven mathematical reasoning and formal verification. From proving theorems in Lean to scaling software verification for the agentic coding era, Shubo lays out a compelling vision for why mathematical infrastructure matters more than ever. The conversation also ventures into homomorphic encryption, multi-party computation, Navier-Stokes, and why the next frontier of computing might just be running on math we haven't discovered yet. [00:00] Guest introductions and backgrounds [00:52] Company founding story [03:01] Axiom Math mission explained [05:15] Software verification applications [16:02] MPC and encryption challenges [24:01] Business model and products [33:49] Spicy Future hot takes

    Betting on Open Source Models to be the future (Chat with Benny, Cofounder of Fireworks AI)

    In this episode of The Infra Pod, hosts Tim Chen (Essence VC) and Ian Livingstone (Keycard) sit down with Benny Chen, co-founder of Fireworks AI, to explore the evolving world of AI inference infrastructure. Benny shares his journey from Meta — where capacity planning meetings made it clear GPUs were heading "up and to the right" — to co-founding Fireworks AI before ChatGPT even launched. The conversation dives deep into why the team bet early on inference over training, how they approached model optimization from horizontal compiler techniques to per-model kernel tuning, and why model customization is the key to unlocking better-than-frontier performance for vertical use cases. Benny discusses the reality of open source vs. closed models, the rise of agentic workloads, and why the real question isn't which model to use — it's which tasks have already been saturated. This episode is packed with technical insights on inference infrastructure, reinforcement learning for model customization, and what it means to truly adopt an AI-native engineering culture. 0:24 Benny's journey and founding Fireworks AI3:23 Early conviction: betting on inference before ChatGPT8:29 Pivoting from PyTorch training to text inference15:42 Horizontal vs. per-model optimization strategies11:14 Open source vs. frontier models: the real gap32:35 How customers engage: PLG to hands-on customization17:37 When to move off frontier models33:42 The future of agentic memory and data sovereignty32:35 Fireworks' differentiation in a crowded market33:53 Spicy Future: AI doomers, bot management, and going fully out of loop

    Building a successful infra product between all the AI apps and model providers (chat with Louis from OpenRouter)

    Tim (Essence VC) and Ian (Keycard) interviewed Louis Vichy, co-founder of OpenRouter, about why he built OpenRouter to de-risk AI app development (end-user pays LLM costs), how it scaled to processing ~5–6T tokens/week, and what OpenRouter is today: a reliable inference routing/control layer across ~60 providers with consolidated billing and reduced vendor lock-in. Louis explains why teams adopt OpenRouter (constant new model integrations, pricing/billing, differing API shapes), how routing focuses on practical heuristics (fallbacks, cost, throughput, latency), and how reliability is achieved via provider failover (e.g., alternate endpoints like Vertex/Bedrock). They discuss agent trends (longer-running agents, small models for routing/classification with specialized downstream models), possible memory support, developer conveniences (e.g., PDF parsing), and enterprise features (security/compliance guardrails, presets). The episode ends with links to OpenRouter chat/rankings pages and hiring for high-agency TypeScript-focused engineers.00:00 Welcome & Meet Louis (OpenRouter Co‑Founder)00:27 Origin Story: De‑Risking AI App Costs (Hackathon Lessons)01:35 First Big Feature: End‑User Pays for Tokens (Sign in with OpenRouter)02:34 From Routing to Rankings: Scaling to Trillions of Tokens03:42 What OpenRouter Is Today: Reliable Inference Across 60+ Providers05:55 Why Teams Adopt It: Avoiding Model API Churn, Billing, and Vendor Lock‑In08:37 Winning Strategy: Don’t Build a “Magic Router”—Optimize Cost/Latency/Throughput18:58 From Chat to RAG + Memory: Building Persistent Agent Context20:37 Developer Bells & Whistles: Auto PDF Parsing and More21:11 Enterprise Readiness: Compliance, Security Guardrails & Model Presets22:22 Customer Growth at Warp Speed in the AI Era23:03 Spicy Future!
