What makes Dupple different

Six things we can show, not just claim.

01

Every story cites its source

Each edition links the primary source behind its stories and ends with what to do about it, so readers can check the facts and skip the feeds.

02

Scores only when there is a basis

A review shows our editorial score only when it rests on our five criteria. A review site's rating names the site, links it and gives its review count, and with neither, the page shows no score. How we rate explains the rules.

03

Prices from the vendor's own page

Where we have checked a vendor's pricing, the review links its pricing page with the date we checked. That share grows as reviews are refreshed.

04

Directories with dated data

Toolradar lists verified pricing and real reviews for software. FinanceRadar puts the verification date on every rate it publishes.

05

Audiences measured weekly

Subscriber counts and open rates on this page are pulled from our email platforms every week and rounded, not typed into a media kit once a year. Techpresso averages a 37% open rate.

06

Advertising is capped and labelled

Each newsletter carries at most three sponsors, at a fixed price known before booking, and campaign reports name the companies that clicked. Every paid placement is disclosed: see our affiliate disclosure.

In their words

The teams advertising with us tend to come back. Here's why.

1,499 unique clicks from one Primary ad
“Sponsoring Techpresso has been one of the smoothest partnerships we've run - and one of the best performing. From the first campaign onward, the team made every step easy and convenient, and the results consistently justified coming back. Top-notch to work with.”

Bartek MarmolowskiCustomer Success Director at SerpApi
3,700 clicks across the campaign
“We ran a time-sensitive campaign for a very specific audience, and Techpresso delivered above their expected ranges across every placement. They were also incredibly responsive and got us live quickly, which was critical for the timeline we were working on.”

The team behind Dupple

Dupple started as one newsletter in 2023. The news was everywhere and the signal was nowhere, so Techpresso became a daily briefing you could finish with your coffee. Readers forwarded it to their teams, and one newsletter became six.

Dupple is still a small, founder-led team. Each newsletter has its own editor and its own sources, and no content farm sits in the middle.
