Emailing without

decision makers respond to an email we sent

Tell us about your customer. We will do the rest.

You know your business best. We know how to deliver its story, product and value to the right audience.

Handcrafted copy

ChatGPT is nice. But we still prefer our brains and 10+ years of experience in copywriting.

Targeted audience

The right message, to the right person, at the right time. The good thing is: We know all three.

Automated sending

Imagine trying to email 1,500 people manually. Or, better yet, don’t imagine it.

What it's like
to work with us


We have been using LeadsOS for several months now. During the first month we booked twelve calls with partners at relevant VC funds. It worked so well with investors that we added sales outreach to the mix.

Martin Studencan

CEO, NextRetreat

We were struggling to gain traction and were running out of leads. LeadsOS not only provided us with a large contact list, but also helped us develop an ideal customer profile to target the audience. We're now seeing rapid growth in our business.

Oldrich Muller

COO, Korkuma

We have greatly benefitted from LeadsOS in our lead generation efforts. They were able to generate sales by connecting us with new partners. Having Filip manage your account in a proactive and dynamic manner is also a big advantage. Highly recommended!

GP, SportsGamer

Our services

We plug ourselves into your existing processes, not the other way around.

Sounds great! But...

Can I trust you?

100%. We have skin in the game, and the reputation of LeadsOS equals our personal reputation. You can see our respective backgrounds on LinkedIn: Filip Malypetr, Robert Tarabcak.

What guarantees do you offer?

We start each cooperation with confidence, but we remain humble. If we don’t generate a positive response to your outreach within the first month, the next month is on us.

What is the source of your contacts?

All data points in your contact list, including email addresses, are publicly available and verified. The main sources are company websites, LinkedIn, and industry-oriented media outlets.

Can I see some of the emails you send?

We’d love to show off, but – all emails we write are crafted from scratch for a specific client, so we treat them as confidential. That said, rest assured that your emails will be unique too.

How about GDPR and other regulations?

We are up to date with the CAN-SPAM Act in the US, CASL in Canada, GDPR in the EU and The Data Protection Act in the UK. In a nutshell: You’re in good hands.

When will I see the first results?

The current record is two days after we launched the outreach for a client. However, this may vary, and it depends primarily on your targeted prospects.

What's your approach to cold outreach?

We send emails we would read. To people who will read them. We treat each and every one of your prospects with respect. No hard sales push, no salesy sleaziness.

Am I commiting for life?

No. Regardless of the service you subscribe for, you can cancel it anytime. There are no strings attached, and all the assets we’ve created as part of our cooperation are yours.

Met locally, work remotely, deliver globally

We’ve been building and growing businesses for over a decade, the last three years together. If there’s one thing we learned on our journey, it’s that no matter how amazing a product or a service is, it will hardly ever sell itself.

And while some people say emailing is dead, we know it isn’t – it helped us gain traction like no other sales channel. Now we’re ready to make it work for you, too
