Can I promote my fintech or investing tool here?
No, the rules ban promoting products, services, or anything you monetize, so direct promotion will be removed.

Rule summary
- No spam or self-promotion: We don't allow promoting products/services or content made by the poster, or advertising anything monetized by the poster.
- No incivility: Guidelines: be civil to others; presume good faith We don't allow: * Personal attacks or insults * Negative descriptions of groups * Slurs or vulgar language * Public discussion of whether content is AI generated. Concerns about rule breaking justify using Reddit’s reporting system or messaging the mod team, not breaking sub rules yourself.
- No off-topic content: Guidelines: stick to finance topics relevant to the Bogleheads passive investment philosophy We don't allow: * Discussion of topics with no clear connection to passive investing * Promotion of non-Bogleheads-related investment strategies such as stock-picking, market-timing, or cryptocurrencies) * Overly-political content: more political than financial, more partisan than necessary, or framing political opinions as facts * Joke/meme comments.
- No non-substantive content: Guidelines: make a relevant contribution, explain your reasoning, support your claims. For example, we don't allow: * Content that isn’t principally your own creation (including AI-generated responses) or that fails to give attribution to its source * Yes/no answers, ticker symbols, emojis, or short answers without explanation * Milestone or progress posts, except for effortposts with extensive background/context * Low quality/effort content such as jokes, memes, or comment chains * Trolling
- No Misinformation: Guidelines: this sub should be a place for high quality information from reputable sources. We don’t allow: * False or misleading information including recommending the use of large language models for answers to financial questions. * Conspiracy theories * Overly certain forecasting of the uncertain future * Extreme alarmism not supported by equally strong evidence
Works well
- A detailed, original analysis of how expense ratios affect long-term returns, with sources cited and no mention of your own product.
- A well-reasoned comparison of two-fund, three-fund, and four-fund portfolios, written in your own words with clear attribution.
- An effortpost explaining a Bogleheads concept like tax-loss harvesting, with extensive background and context and no links to monetized content.
- A thoughtful question about fixed income allocation in retirement, framed around the Bogleheads philosophy and supported by your own reasoning.
Avoid
- Promoting your own product, service, or monetized content, which the rules call spam or self-promotion.
- Posting about stock-picking, market-timing, or cryptocurrencies, since the community only welcomes passive investing topics.
- Dropping a short answer, ticker symbol, or emoji without explanation, because the rules require substantive contributions.
- Using AI-generated text for posts or financial answers, which the rules explicitly ban.
- Posting milestone or progress updates unless they include extensive background and context, since plain milestone posts are not allowed.
What r/Bogleheads Is For
This community is for passive investors who follow Jack Bogle's philosophy of diversifying with low-cost index funds and letting compounding do the work over the long term. People post here to discuss broad-market low-cost indexes, split between equities and fixed income, and to encourage each other to buy, hold, pay low fees, and stay the course. The conversation stays tightly focused on finance topics that connect to the Bogleheads passive investment approach, and the rules push back hard against anything that drifts into active management, speculation, or politics.
Rules That Matter Before Posting
The rule called 'No spam or self-promotion' is the first and most important one for anyone doing marketing-adjacent work, because it bans promoting products, services, or anything monetized by the poster. The rule named 'No off-topic content' will catch you if you drift into active trading, stock-picking, market-timing, or cryptocurrencies, since the community only wants discussion tied to the Bogleheads passive investment philosophy. The rule called 'No non-substantive content' matters because it requires you to explain your reasoning and support your claims, and it bans AI-generated responses outright. The rule named 'No Misinformation' adds another layer, banning overly certain forecasting and any recommendation to use large language models for financial questions.
What To Post
A good post here is a genuinely useful contribution to passive investing discussion, written in your own words, with clear reasoning and attribution for any sources you cite. If you are a founder or marketer, the only way to participate is to add value without linking to or naming your own product, because the self-promotion rule leaves no room for even soft promotion. You could share a detailed analysis of fund expense ratios, a comparison of asset allocation approaches, or a well-sourced explanation of a Bogleheads concept, as long as the content is principally your own creation and not AI-generated. The community rewards effortposts with extensive background and context, so depth and honesty matter more than reach.
What To Avoid
You will get removed or banned if you promote a product, service, or anything you monetize, because the first rule bans all spam and self-promotion. You will also get removed if you post about stock-picking, market-timing, cryptocurrencies, or any strategy that is not Bogleheads passive investing. Short answers, ticker symbols, emojis, and milestone posts without deep context are treated as non-substantive and are not allowed. AI-generated content is banned, and so is recommending large language models for financial answers. Misinformation, conspiracy theories, overly certain predictions about the future, and extreme alarmism without strong evidence will also get pulled.
