What we read, and what we recommend you read.

Warrillow's eight value drivers framework, the most-cited operator-facing reference on what buyers pay for in lower-middle-market businesses. Register is pop-business-book and oriented toward sub-$10M operators, which limits depth on the $5M+ EBITDA founder, but the framework remains the right starting point for any founder who has not yet thought systematically about buyer-side value drivers.

The buy-side perspective on lower-middle-market acquisitions, useful for understanding what the other side of the table is thinking. Deibel writes for searchers and self-funded buyers, which makes the book unusually clear on the diligence process and the decision criteria a buyer actually applies.

What lower-middle-market private equity actually feels like from inside a long-hold operator's seat. Beshore's Permanent Equity is one of the longer-duration buyers in the lower middle market, and the book is written from inside the work, not from inside the marketing.

The reference text on private-company valuation. Academic in register. Damodaran's chapters on private-company illiquidity discounts, key-person discounts, and growth-rate sensitivities are the empirical anchor most other operator-facing books reference without naming.

Read for register and discipline, not for direct applicability. Marks writes about risk and judgment in markets, but the underlying intellectual habits, second-level thinking, the asymmetry between conviction and certainty, the patience required to wait for a good price, are the habits the founder needs to bring to a transition decision.

Eight operator-CEOs framed as capital allocators. Thorndike's argument is that the discipline of capital allocation, which buyers spend most of their time on, is also the discipline that produces the businesses buyers are most willing to pay for.

The most-cited reference for plain-language institutional writing on markets, risk, and the discipline of independent thinking. Free, published roughly monthly, archived back to 1990.

Paid subscription. Single-voice analysis of technology and media strategy at a sustained level. The reference for what disciplined publication economics look like when a single editor controls the editorial calendar.

Long-form business deconstruction at a sustained editorial level. Gabriele's strength is in connecting specific company decisions to broader strategic patterns; the pattern recognition is useful for founders thinking about market timing and buyer behavior.

The most-referenced empirical database on lower-middle-market private-company transaction multiples and discounts. Subscription. The reference for any quantitative claim about transaction multiples or discount stacks in the lower middle market.

Quarterly read on lower-middle-market private equity activity. Free, published by Capstone Partners. The reference for current-state buyer activity in the lower middle market.

The publisher of Pratt's Stats and a wider library of valuation methodology and case data. Subscription. The reference for methodology questions on private-company valuation and the discount stack.

The research arm of the Cordis Group family. Publishes white papers, position papers, and sector reads on lower-middle-market preparation, discount-stack discipline, and the five risk axes. Frequent source in Foundry citations because the citation pattern reflects where the most-referenced research in this space actually is.

Deal-flow news and commentary on lower-middle-market M&A. Free with registration. Useful for founders who want a regular read of current-state deal activity in their sector.

Institutional deal coverage across global M&A. Subscription, expensive. Most lower-middle-market founders will not need it; advisors and bankers serving the segment usually do.

M&A news with a meaningful focus on private-company transactions in the U.S. lower middle market. Subscription. Useful for founders who want sector-specific deal coverage without an academic register.

Practitioner association content for lower-middle-market M&A advisors. The conference programming and the published guidance documents are the most useful items for founders who want to understand the advisor side of the market.

Founder of Permanent Equity, a long-hold PE firm operating in the lower middle market. Writes and speaks publicly with a register most operator-CEOs find immediately useful. Author of The Messy Marketplace.

Buy-side educator with a large audience of aspiring acquirers. Useful counter-perspective for founders who want to understand how the buy-side teaches itself to buy.

Founder of Hampton, a paid peer forum for founders. Writes and podcasts on founder loneliness as a product category, which is structurally adjacent to Foundry's audience even though the product positioning is different.

Interview format done at a sustained level. The Invest Like the Best podcast covers institutional investors, operators, and founders, and the editorial discipline of the show is the closest podcast analog to what Foundry attempts in long-form writing.

Author of Buy Then Build. Educates the search-fund and self-funded acquirer audience. Useful for founders who want a sustained read of buy-side thinking from someone who is not pitching them anything.
