How we picked and ordered this list

We selected a founder-focused newsletter and an AI newsletter with public advertising pages, plus Dupple's technology newsletter as a broader context. Entries are alphabetized by publication name, not ranked by audience size or campaign performance. The list is not exhaustive. Confirm current availability and the audience evidence relevant to each proposed placement.

Sources were checked on 5 November 2026: Dupple's Techpresso page, advertising page and audience data; The Rundown AI advertiser page; and TLDR's founders audience page. Publisher descriptions and figures are self-reported unless an independent audit is identified.

Founder newsletter options at a glance

Table: publisher descriptions and buying questions, sources checked 5 November 2026.

The publishers' figures describe different populations and are not independently verified ad views. Techpresso's count is a Dupple platform subscriber figure. TLDR's subscriber count is its own statement. The Rundown uses different audience scopes on its advertiser page, so ask which one covers the proposed newsletter. A founder-related context does not prove that every recipient owns a company or will buy a product.

Techpresso: Dupple's broader technology context

Dupple describes Techpresso as a technology and AI newsletter and offers sponsorships. The Techpresso page states 790,000+ subscribers as of November 1, 2026. That platform count is not the number of founders in an issue or a count of people who see an ad. Ask which issue, format and reporting are available for the offer.

Our data, verified November 2026: In Dupple's voluntary post-signup quiz, 7,590 founder and senior executive respondents answered an AI-tools question between 5 August and 3 November 2026; 70.4% reported paying for at least one AI tool. The AI-tools CSV records the sample and the data page explains the method. The group includes founders and senior executives; it is not a founder-only count, a Techpresso-only sample, all subscribers or a guaranteed issue audience. Answers are self-reported and Dupple's quiz and platform figures are not independently audited.

Dupple describes an in-issue Primary Ad and a separate dedicated send. Ask for the available format, creative requirements and a sample report. The founders audience page offers additional context but does not make the quiz result a guaranteed placement audience.

The Rundown AI: AI editorial context

The Rundown AI's advertiser page describes an AI-focused publication and invites sponsorship inquiries. Its page uses audience figures with different scopes, so ask which figure applies to the specific newsletter and issue before comparing it with a subscriber count. The page's claims are publisher statements, not an independent audit or a guarantee of ad views.

An AI-focused context may be relevant to a startup product that helps teams use or build AI tools. Define whether the offer is intended for a founder, an engineer or a business user; these roles can overlap but have different tasks. Ask for a recent issue, placement preview and current reporting definitions. Editorial context alone does not establish an individual reader's role or purchasing intent.

TLDR Founders: founder-focused context

TLDR's founders audience page describes a founder-focused newsletter and states 380,000 subscribers. TLDR describes newsletter ad placements on its advertiser pages. Ask which issue and format are available and how the subscriber figure was collected. Its figure is a publisher claim checked on 5 November 2026, not a verified count of ad viewers.

A publication explicitly focused on founders may fit an offer for startup operators. Ask the publisher about the roles represented in the proposed newsletter and whether any audience breakdown is descriptive or selectable for a placement. Do not assume that a founder-related newsletter contains only founders or that all readers are in the same stage of company building.

Define the startup task

Founders may evaluate products for hiring, fundraising, customer development, engineering, finance or marketing. A workflow for a newly formed company may differ from one for an established team. Describe the task, intended user, organizational prerequisites and next action before selecting a publication. A generic claim that a product helps startups is less informative than an explanation of the work it supports.

Separate the person using a tool from the people involved in a purchase. A founder can delegate evaluation, while a finance or security team may need to approve a deployment. Dupple's AI-tools quiz result records a self-reported behavior among respondents; it does not establish that a reader needs your product or can approve its purchase. Define the use cases and roles that make an inquiry relevant to your team.

Choose an offer appropriate to the reader's likely need for context. A technical guide can explain a workflow; a product tour can show it; a demonstration request requires a clearer commitment. Tell readers what happens after the click and state material conditions. Test the destination, any form and the confirmation on mobile and desktop.

Compare actual proposals

Request the publication, issue date, placement, creative specifications and an example report. Ask how each audience number is defined and when it was measured. Subscribers, active readers, survey respondents and ad impressions are distinct units. A figure covering several channels should not be silently treated as a newsletter-only count.

For a founder or executive breakdown, request the question, sample and method. A voluntary survey describes the people who answered without establishing the characteristics of nonrespondents. Ask whether a breakdown is descriptive or an available selection for the proposed booking. Dupple's quiz does not establish a purchasable founder-only segment.

The newsletter buying guide provides a practical checklist. The Primary Ad guide and dedicated-send guide explain two formats. Other publishers may use different names and positions, so ask for a preview and clarify what the proposed report measures.

Prepare and review the creative

Provide the publisher with the product, intended user, approved claims, destination and a named approver. Include material prerequisites and evidence for factual statements. If describing a customer result, establish permission and explain the relevant period and circumstances. One result is not a guaranteed outcome for other customers.

Request a preview showing how the paid placement is identified. The US Federal Trade Commission's native advertising guide, checked 5 November 2026, discusses disclosures when advertising resembles editorial content. Requirements depend on the placement and jurisdiction. Keep the approved creative, issue date and tracking link together for the team reviewing results.

If the offer collects contact details, explain what happens next and route submissions to the right person. Agree on the information needed for follow-up without treating every completed form as a qualified opportunity. A founder reading a newsletter can have a different use case from a sales team, developer or investor reading the same issue.

Measure the result with defined units

Define the desired action and qualified outcome before launch. A documentation visit, event registration and sales inquiry are different events. Use consistent campaign tags and compare the publisher's report with your own analytics while allowing for consent, redirects and filtering. Review later outcomes after a defined follow-up period.

Dupple says its reports include opens, clicks, click-through rate, benchmarks and corporate domains that engaged. Ask each publisher for the definitions that apply to the format. Reported email opens do not establish that someone saw the ad. Apple's Mail privacy guidance, checked 5 November 2026, describes background downloading of remote content under privacy settings. The CPM guide explains why those units differ.

The sponsorship ROI guide describes connecting activity to a business objective. Preserve the offer, creative, timing and placement with the result. When several factors differ across campaigns, the difference cannot be attributed to the publisher alone.

What we could not verify

Publisher figures are self-reported; Dupple's platform and quiz data is not independently audited. The Rundown's cited page uses audience figures with different scopes, and Dupple's quiz does not establish the number of founders in a particular issue. We cannot verify audience overlap, individual purchasing authority or a campaign outcome. Open rates are not directly comparable across platforms without understanding their definitions and filtering.
