Announcing @LeadbayAI $4.3M to kill everything you're doing with sales.

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.

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."

Today, introducing @LeadbayAI MCP.
My bet after building it: the SaaS interface won't exist in 6 months.
The future of sales & marketing teams is one prompt away:

It might be time to stop doing sales the way teams have in 2026 and start new initiatives - self-improving agents are now available and can 10x reps’ lives.
