Are You Currently Struggling With...

Unpredictable Pipeline

You never know where your next qualified lead is coming from, so revenue swings month to month instead of growing steadily.

Agencies That Overpromise

Tired of paying a flat retainer for 'brand awareness' instead of an actual number of qualified calls on your calendar.

Hi, I'm Diego.

I founded Upstart Labs with one mission: take the guesswork out of B2B pipeline generation.

Every domain, every mailbox, every sequence is something I set up and monitor myself, because deliverability is the difference between a system that books calls and one that quietly lands in spam while you keep paying for it. That's why we work on pure performance. You only pay for the qualified calls we actually book.

Let's Talk!

FAQs: Everything you need to know.

How fast can we expect results?
Setup takes about 48 hours, followed by roughly 2 weeks of mailbox warmup before we send at full volume. Most clients start seeing qualified replies within 3-4 weeks of kickoff, with call bookings following shortly after.
Do you work with any industry?
We work with B2B service businesses that have a clear, provable ROI story for their ideal client. If your offer converts well on a straightforward pitch, our system can turn that into consistent, qualified pipeline.
What is the guarantee exactly?
You only pay for qualified sales calls that actually show up. If a call doesn't show, you don't pay for it. No contract lock-in, no risk on your end.
How much of my time is required?
Very little. We just need one 30-60 minute onboarding call to get started. After that, you simply show up for the qualified calls we book you.
