Merge CEO Shensi Ding on why most agent tools fail

Shensi Ding (Co-Founder & CEO of Merge) started building integrations six years ago, before AI was the market. Now OpenAI, Perplexity, and Factory run on Merge’s connectivity layer. In this episode of Navigators, Paul sits down with her to talk about what it actually takes to connect agents to the systems they need. When Merge benchmarked its tools against public MCP servers, it found a 99.999% success rate compared with roughly 60% for public servers. Shensi says most of those public servers are side projects and marketing that nobody maintains. That is also why AI security hasn’t had its big incident yet: the tools fail before any PII can leave. She explains why that is about to change, why it’s irresponsible to run AI without a DLP layer, and why you can’t vibe code critical infrastructure. Chapters: 0:00 Intro 1:19 What Merge builds: the connectivity layer for AI 4:02 The agentic-tooling gap MCP opened 5:14 Why thousands of tools is a security risk 6:13 "They only see what's on the menu" 6:55 Why it's irresponsible to run AI without a DLP layer 7:39 Merge for Workforce: governance for IT 12:40 99.999% vs 60%: benchmarking tool reliability 12:59 Is MCP the right protocol? 18:30 Why the founder sets the AI ceiling 21:05 996, barrels and ammo, and hiring for AI 37:57 Why humans become the blocker to the singularity Browserbase gives AI agents a browser to operate in.

The $1B founder of Fireflies on why he gives his software away for free and what he charges for

Fireflies gives away unlimited meeting recordings and transcriptions. Krish Ramineni (Co-Founder & CEO of Fireflies) says that was the plan from day one: commoditize yourself before someone else does it for you. In this episode of Navigators, Paul sits down with Krish to talk about what happens to software when models drive most of the interaction. Krish thinks most SaaS will be given away for free and that companies will charge for the agentic work instead. If you don't become agentic, you become a data source or a connector inside someone else's model, and all the value goes to them. He explains why you can't vibe code a CRM, why seat-based pricing breaks when companies run with fewer people, and why Salesforce had to decide whether to go headless. They also cover how Fireflies hit unicorn status on $19M raised, how open weight models made the free tier possible, and why Fireflies routes across seven to 10 model providers. 00:00 Intro 01:48 Years of failed products before the tech caught up 04:25 Why meetings were the data nobody could capture 07:21 Running Fireflies on Fireflies with 130 people 08:41 The support agent that handles more tickets than any human 10:37 Why Fireflies won't train on customer data 11:55 Open weight models and an unlimited free tier 13:19 Why app companies need a model router 16:05 You can't vibe code a CRM 17:32 SaaS goes free, agentic work gets paid 19:47 Become infrastructure or become a connector 23:20 A unicorn on $19M raised 25:17 The second act: email, Slack, and a context graph Browserbase gives AI agents a browser to operate in.

LangChain CEO Harrison Chase on the infrastructure bet he got wrong

Harrison Chase (Co-Founder & CEO of LangChain) has rebuilt his product stack four times since 2022, chasing models that kept changing underneath him. In this episode of Navigators, Paul sits down with him to talk about what LangChain got right, and the one piece of infrastructure it built years too late. Harrison admits the team underestimated how massive the demand for raw inference would become, and how big general-purpose coding agents would get. He walks through the shift from LangChain to LangGraph to DeepAgents, why sub-agents rarely work the way people expect, and why LangChain now runs its own hiring, content, and coding work through internal agents exposed in Slack. Topics covered: The gateway LangChain should have built a year earlier Why agent capability converging on human capability changes the tools debate Code mode: why agents writing code beats agents using human-style tools Running GTM, content, and coding agents entirely inside Slack Why sub-agents need to own whole tasks, not small pieces The agent identity problem: delegated access vs. service accounts Why LangChain's own AI slop problem got bad enough to need a Slack emoji Navigators is a series by Browserbase where we sit down with AI leaders navigating the future of what's happening in AI today.

A $5 Billion Fintech company CEO on the framework behind every product decision

Immad Akhund (Co-Founder & CEO of Mercury) uses what he calls the cosmic cube to decide what Mercury builds next: one axis for customer type, one for product, one for compliance and infrastructure. In this episode of Navigators, Paul sits down with him to talk about why that space is functionally infinite, and why trying to expand into all of it at once is how companies lose. Immad also explains the two-year mistake of waiting to launch a corporate credit card, why he treats every new product like a fresh seed-stage startup inside Mercury, and why talent, not capital, is the real limit on how many bets the company can run at once. CHAPTERS: 00:00 Why 1-on-1s stopped working once he was managing execs 07:34 Agentic cards: letting AI spend on your behalf 11:09 Why fintech is three times harder than software 13:50 Chewing glass: getting bank-charter ready 16:08 Reaching the edge of knowledge in six months 28:26 Killing 1-on-1s and what Jensen Huang has to do with it 36:39 The "cosmic cube": how Mercury picks its next bet --- Navigators is a series by Browserbase where we sit down with AI leaders navigating the future of what's happening in AI today.

Latent Space's Swyx on why 80% of GDP isn't automated yet

Shawn Wang, aka Swyx, has spent the last several years narrating the AI boom through his podcast Latent Space and the AI Engineer conference. In this episode of Navigators, Paul sits down with him to talk about how far agents have actually come, and why most of the economy hasn't caught up yet. Swyx points to OpenAI's own research showing that roughly 80% of US GDP could be automated by agents today. The holdup isn't the models, he argues, it's everything downstream: cost, reliability, and a hardware shortage severe enough that people are scavenging memory out of old MacBooks to keep up with demand. He also unpacks the split between "agent labs" chasing domain specificity and "model labs" chasing AGI, and where he thinks the next wave of AI begins. Topics covered: Why 80% of GDP could be automated by agents right now The real reason adoption is lagging behind capability Agent labs vs model labs: Cursor, Sierra, and domain-specific bets Pre-training, mid-training, and post-training, explained simply The chip and memory shortage nobody's talking about Why "diffusion is cope" divided the AI industry The self-driving car tradeoff coming for agents Follow Navigators: https://x.com/pk_iv https://x.com/browserbase Follow Swyx: https://x.com/swyx Latent Space podcast: https://www.latent.space

Hightouch's founder on why AI marketing lags behind coding

This data turned AI marketing founder, Kashish Gupta, thinks the reason AI hasn't taken over marketing the way it's taken over coding comes down to one word: taste. In this episode of Navigators, Paul talks with him about what it actually takes to teach a model a brand's aesthetic, and why most companies trying to do this are being lazy about it. He explains why marketing lacks the verifiable feedback loop that made AI adoption easy in customer support, and how his team spent over a year building the context layer needed to translate a creative director's unspoken instincts into something a model can act on. He also talks about the subagent whose only job is finding ideas a brand's competitors haven't tried yet, and why he believes the next leap in AI marketing depends less on smarter agents and better prompts, and more on models that generate images and video without inventing details that were never there. Topics covered: Why marketing lags coding: no verifiable loop, and taste is subjective Turning a creative director's unspoken instincts into something a model can query The subagent built to find whitespace competitors haven't touched Why enterprise customers, not SMBs, were the only ones who could adopt this Going from access to insights to content: how one problem led to the next Where the next inflection point comes from: instruction-following and image generation How coding agents changed the day-to-day of running the company itself Navigators is a series from Browserbase where we speak with AI leaders navigating the future of building with AI.

The CEO of an auth company on agent sign up, auth, and MCP

Michael Grinich (CEO & Co-Founder of WorkOS) has spent seven years making software enterprise ready, and the last two watching AI companies become his biggest customers. In this episode of Navigators, Paul sits down with him to talk about what's still broken at the front door of every AI product. Michael makes the case that coding agents already choose your vendors for you, they just can't finish the job: signup forms are built to block automated traffic, so a human still has to step in and register the account. He also gets into why MCP is still growing despite the hype cycle moving on, why he thinks SDKs are becoming unnecessary as agents write their own, and why the next wave of growth will come from agents, not people, filling out your forms. Topics covered: "Stripe for enterprise features": what WorkOS actually sells How an SSO and SAML company ended up as AI infrastructure The biggest mistake founders make: staying in the pre-PMF experimentation mindset Why nothing works unless the management team is AI pilled first auth.md, the missing front door for agents Is MCP dead? The higher-intent signal hiding in MCP connections Why SDKs are going away and coding agents write their own

A $4B founder on the one thing holding back every AI agent

Aaron Levie (Co-Founder & CEO of Box) has run Box through three platform shifts: cloud, mobile, and now AI. In this episode of Navigator, Paul sits down with him in Redwood City to talk about what's actually changing as agents take over knowledge work. Aaron makes the case that most "AI problems" are actually context problems. Agents need access to the 90%+ of enterprise data that's unstructured, and giving them the right information in a tiny window of time and space is the real unsolved challenge. He also breaks down why there's a growing gap between model capability and real-world adoption, why the applied layer will stay valuable even as frontier models get more powerful, and why founders building today need to treat go-to-market as the new scarce resource now that building software is cheap. Topics covered: Why agents use data more like people do than computers ever did The "model overhang": why capability is outpacing adoption Why Silicon Valley will always move faster than the real economy, and why that's fine How Box is rebuilding its own ops around agents internally Headless SaaS, agent-native pricing, and what happens when agents outnumber humans 100 to 1 Why the applied layer wins even in a bitter lesson world Aaron's advice for founders starting companies from scratch today
