Frederik Jakobsen's Story

1) Can you introduce yourself?
I'm Frederik Jakobsen, founder of Danish Lead Co (danishleadco.io), aB2B outbound agency that builds and runs cold email systems that booksales meetings for B2B companies in the US and Europe. We send around500,000 emails a month for our clients. I also run DealSource Systems (dealsourcesystems.com), which does proprietary deal sourcing for private equity and M&A firms, and SourceRank AI.

2) How do you use Icypeas in your business activity?
Icypeas is the first email finder in the waterfall behind every DanishLead Co campaign. When we build a list, every contact without averified email goes to Icypeas first, through the API, before anyother provider is touched. We have been on the 200K credit plan sincelate 2025.

3) What is the impact on your business since you integrated Icypeas in your waterfall?
The numbers from our own pipeline since we started logging every call in May 2026:

- 89,806 Icypeas lookups across our client campaigns

- 12,674 verified email addresses in our database came from Icypeas,more than from any other paid finder in our waterfall

- Only 66 of roughly 62,000 live API calls failed, so it just runs inthe background without anyone babysitting it

- No charge for misses, which matters when you run tens of thousands of lookups a month: we only pay for emails that are actually found.

For an agency where deliverability and cost per lead decide everything, putting Icypeas first in the waterfall gives us more verified contacts per dollar and fewer leads that ever need a second,more expensive provider.

Danish Lead Co. is a fully managed B2B outbound agency that builds automated lead generation systems to book qualified sales meetings with key decision-makers.
