Six daily briefings, one small team, 730,000 inboxes.
Dupple publishes newsletters, tool reviews and training for professionals who would rather read five minutes of signal than an hour of feeds. Independent, founder-run, and built to be read, not scrolled past.
Audience figures match our media kit, updated September 2026.
How it started
Dupple started as one newsletter in 2023. The problem was obvious to anyone working in tech: the news was everywhere, the signal was nowhere. Launches, funding rounds, security advisories and model releases landed all at once, and nobody had the time to sort them.
Techpresso was the answer: a daily briefing you could finish with your coffee. Readers forwarded it to their teams, their teams subscribed, and one newsletter became six. The same recipe now runs for developers, security teams, finance, marketing and AI.
Along the way we started reviewing the tools our readers kept asking about, then built two directories to rank them properly, then an academy to teach people how to use them. Every product on this page exists because readers asked for it first.
The newsletters
Every edition is written the same way: primary sources first, the number the wires missed, and a last line that tells you what to do about it. Free, daily, unsubscribe in one click.
Techpresso
FlagshipTech and AI. The daily briefing that started it all.
MarketingShot
Growth, brand, and the tools marketers actually ship with.
Finpresso
Markets, fintech and the money behind the headlines.

Devshot

AIpresso
Models, agents and the companies building them.
Beyond the inbox
Reviews and directories that rank on evidence, and training for people who learn by doing.
Tool reviews
425+ hands-on reviews of AI and business software, with pricing checked against the vendor and the limitations written down, not just the strengths.
Toolradar
A software directory that ranks tools on real usage data, verified reviews and pricing, so teams can compare before they buy.
FinanceRadar
Rankings of credit cards, savings accounts and investing products, scored on published terms and dated rates. Scores are not for sale.
AI Academy
Practical courses on using AI at work, built around real tasks rather than theory. Short, hands-on, and updated as the models change.
How we work
Three rules that decide what gets published and what gets cut.
Primary sources first
The filing, the advisory, the company release. Aggregators are a second cite, never the only one. If we could not read the document, we say who did.
Rankings are not for sale
Sponsors buy placements, clearly labelled. They cannot buy a score, a rank or a review. Our affiliate disclosure spells out how we make money.
Small team, every day
No content farm, no middle layer. A handful of people own their verticals end to end and ship six editions before most readers wake up.
