Transforming the job of sales rep today with a $4.3M funding 👇🏽
Announcing @LeadbayAI $4.3M to kill everything you're doing with sales. Corgi, Deel, L'Oréal recently told us: "We found in 10 min on Leadbay what we couldn't in 6 months with Clay and a GTM agency." Leadbay qualifies the millions of data-signal-scarce companies nobody could find before. This is how it works:

Announcing the death of people interfaces. We’ve reached the tipping point where people trust AI enough to stop checking lead quality, so they can just let agents do the work.
Most sales teams are competing for the same companies. Not necessarily because they're the best customers, but because they're the easiest to find. They have LinkedIn profiles, public hiring activity, and enough online signals to show up in every prospecting database. But plenty of good businesses don't leave that kind of trail. @ludogranger kept noticing this when visiting customers. He'd look at their prospect databases and find that he could sometimes identify roughly three times as much additional market opportunity. The companies were there. The sales tools just weren't finding them. A hotel, a restaurant, or an early-stage startup might be a perfect customer. But if it's not generating the right online signals, it can be almost invisible to traditional prospecting software. That became the problem Ludo wanted to solve with @LeadbayAI Instead of relying only on the signals everyone else is tracking, Leadbay tries to learn how a good salesperson evaluates a company. It looks at your business, identifies what a promising customer might look like, and uses feedback from the leads you pursue to get better over time. But Ludo isn't trying to build another database with more companies in it. He thinks the way salespeople use databases is changing altogether. During SF Tech Week, he used Claude from his car to work with five highly qualified prospects rather than sorting through thousands of accounts. Then he told the agent how to handle outreach and follow-ups. That's the distinction he's betting on. Finding more companies matters, but knowing which ones are worth pursuing matters more. Especially when the person making that first decision isn't a person anymore. It's an agent. 🎙️ @ludogranger, CEO & Co-Founder, @LeadbayAI on Fondo @thestartpod with Guest Host: @kmkaric, COO & Co-Founder, @ploid_ai (YC F26) 01:42 Why everyone is chasing the same companies 02:08 The untapped market traditional sales databases overlook 02:34 How Leadbay can expand a company's addressable market 02:51 Why startups should build something agents want 03:17 The shift from human interfaces to AI agents 03:48 How AI identifies promising businesses with limited online data 04:19 Teaching AI to recognize and improve lead quality 05:01 Finding five highly qualified prospects instead of 5,000 05:29 Trusting AI agents to coordinate outreach and follow-ups 07:04 Why qualified data is the fuel for AI-powered sales

Kicked off SF Tech Week with @BrightData Here’s what I shared: 1. Death of the user interface. Birth of the agent interface. 2. Every app becomes an agent. 3. Trust is the missing piece for the interface to disappear. 4. Build for agents - a much bigger market is coming. Your next users might not be humans.

Best opportunities are most of the time counterintuitive: - People will sleep in a stranger’s home instead of a hotel: @Airbnb, - People will ride in a stranger’s car instead of a taxi: @Uber, - People will buy products online instead of in stores: @amazon, - Sales is a blue ocean, @LeadbayAI You just need to see what others can’t. Some people see AI prospecting as a highly competitive market. We, ou investors, and - our partner Garry Tan - believe it’s a blue ocean opportunity. Many thanks for this piece of content @insart.

Until today, CEOs bought many AI tools without transforming the daily work of their teams. It resulted in more costs, no growth. Time for CEOs to deeply transform the way their teams work to bring a new type of growth that wasn’t possible before.
To get macro productivity gains, managers and CEOs have to greenlight radically different staffing and workflow plans To date I don’t think they’ve done it Be prepared for this to take 10 years not 2

We’ve been the first in the world to develop a self-improving MCP. Now is your opportunity to join as an early employee at what will become the first $B MCP-native company.
Hi all 🤘🏻 - we are hiring 3 Forward Deployed Engineers = technical & socially skilled. In 2026, there is a rare skill that only a few people have - even if they don't fully realize it yet. Our current FDE is 19. He's technical, a builder - and highly socially skilled without knowing it. It turns out to be a formidable enabler: listening to our customers, showing them how to build their specific workflows, and ensuring they grow at a speed that wasn't possible before. The more customers he visits, the more skilled he becomes, and the more CEOs he saves from "growth inefficiency." You'll see in the comments that this job post has the power to be life-changing. I also believe this job is your best gate to learn everything you need in the field to later become a formidable YC founder. So if you have a friend, a cousin, a daughter/son, a nephew, your boss's daughter/son - or anyone you believe must take this opportunity - please SHARE the job post. APPLY.

What is @claudeai, @OpenAI and @Copilot without qualified leads ?
A customer described @LeadbayAI better than I ever could: "Leadbay qualifies leads for my Claude." Death of the software interface, birth of software MCP. Here is our fresh new look.

Customer stories on the ground.
5:37am today in Lille. Our taxi driver explains me what he built with Claude to take over the back office of his 5-driver company. Under a single prompt, I plugged in @LeadbayAI MCP and agents are now prospecting any CEOs traveling early in the morning. Time for every creative and entrepreneur to grow and thrive with AI. 🇫🇷🇫🇷🇫🇷

It's already version 21 of our MCP. We gave it to our users early and they tell us… "I qualified thousands of companies in under 5 minutes. It would have taken my team a year." A new world is being built. And this new world is now just one prompt away — simply type npx -y -p @leadbay/mcp@latest installer in your Claude.

It's not just another MCP on Claude. 4 reasons it's life-changing: 1. Qualifies the most data-scarce markets with human-like intuition - beyond filters, beyond signals. 2. Adapts to your context from something as simple as a domain. 3. Self-improving: learns from your wins, losses, and even your prompt frustrations. 4. The first UI component library that makes Claude's HTML artifacts actually interactive.

Last week, @Microsoft and @nvidia asked me to give an avant-première on the @VivaTech stage. I promise your daily life as a sales rep or marketer won't be the same after the 20-min "Mastering Claude + Leadbay MCP."
