Training Example: 37signals – Review the Data, Give Your Score & Compare to the Real AI Evaluation

Industry Context — Common BS Fingerprints in Software, SaaS & Tech Products
Generic Claims: the all-in-one platform, trusted by thousands of companies, increase productivity by X percent, save hours every week…
Red Flags: AI claims without explaining what the AI does, customer logos without case study or testimonial evidence, no live product access or demo, SOC 2 claims without audit period or report availability…
Semantic Drift Patterns: homepage claims AI-powered but product is rules-based, claims enterprise-grade but pricing page shows startup tiers only, homepage shows Fortune 500 logos but case studies are small businesses, claims all-in-one but integration page shows critical missing pieces…
Proof Expectations: live product demo or free trial access, specific feature documentation with screenshots, verified customer logos with published case studies, third-party review scores on G2, Capterra, or TrustRadius…

On top of making Basecamp and HEY, we write books about what we’ve learned running our own business. They’re filled with practical advice you won’t find elsewhere.

[IMG: Shape Up]

[H3] Shape Up
Shape Up is for product development teams who struggle to ship. Written by the innovators behind Basecamp — one of the biggest and longest-running software as a service apps — the book gives teams the tools to address the risks and unknowns at each stage of the product development process. Full of eye-opening insights, Shape Up will help you break free of “best practices” that aren’t really working, think deeper about the right problems, and start shipping meaningful projects your team can celebrate.

[IMG: It Doesn’t Have to Be Crazy at Work]

[H3] It Doesn’t Have to Be Crazy at Work
Chaos shouldn’t be the natural state at work. Anxiety isn’t a prerequisite for progress. Sitting in meetings all day isn’t required for success. These are all perversions of work — side effects of broken models and “best” practices. This book treats the patient, calls out false cures, and pushes back against ritualistic time-sucks that have infected the way people work these days.

[IMG: REWORK]

[H3] REWORK
New York Times bestseller! Most business books give you the same old advice: write a business plan, study the competition, seek investors, yadda yadda. If you’re looking for a book like that, put this one back on the shelf. REWORK is the perfect playbook for anyone who’s ever dreamed of doing it on their own. Entrepreneurs, small-business owners, and artists who don’t want to starve will all find valuable guidance in these pages.

[IMG: REMOTE]

[H3] REMOTE
Office not required. As an employer, restricting hiring to your local region means you’re not getting the best people you can. As an employee, restricting your job search to companies within a reasonable commute means you’re not working for the best company you can. REMOTE shows both employers and employees how they can work together, remotely, from any desk, in any space, in any place, anytime, anywhere.

[H3] Getting Real
The smarter, faster, easier way to build a successful web application. Getting Real is packed with keep-it-simple insights, contrarian points of view, and unconventional approaches to software design. This isn’t a technical book or a design tutorial, it’s a book of ideas. Anyone working on a web app — including entrepreneurs, designers, programmers, executives, or marketers — will find value and inspiration in this book.

[H3] Seven Shipping Principles
Core fundamentals that inform how we go about building — and shipping — great software at a sustainable pace.

[H3] The 37signals Guide to Making Decisions
A company is essentially two things: a group of people and a collection of decisions. How those people make these decisions is the art of running a business. This guide shows how we do it.

[H3] Why We Choose Profit at 37signals
For over two decades, we’ve been outspoken about running a profitable, financially responsible company in an industry that has become incredibly proficient at losing buckets of money. While everyone else was celebrating burning cash, we chose profit instead. We still do. Here’s are some reasons why.

[H3] What Influenced Us
If you want to learn the 37signals view of the world, it helps to know the influences that helped form it. We’ve been around since 1999. Since then there’s been a number of key influencers that have marked the company culture.

[H3] The 37signals Guide to Internal Communication
The how, where, why, and when we communicate. Long form asynchronous? Real-time chat? In-person? Video? Verbal? Written? Via email? In Basecamp? How do we keep everyone in the loop without everyone getting tangled in everyone else’s business? It’s all in here.

[H3] Group Chat: The Best Way to Totally Stress Out Your Team
The perils of the modern communications conveyor belt that never ends, divides your attention, fractures your time, and chains you to FOMO.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

https://37signals.com 📍 Industry: Software, SaaS & Tech Products
9 BS / 100

A rare example of a high-substance, low-BS digital presence that prioritizes intellectual clarity over marketing conversion. It loses points only for technical schema omissions and a refusal to link its boldest historical claims to external verification sources. This is a manifest, not a sales pitch.

Integrate Person schema into the JSON-LD to explicitly name and link the founders to their external digital footprints. Add direct outbound links to the New York Times bestseller list and other third-party accolades mentioned in the book descriptions. Replace the anonymous review on the thoughts page with a verified, linked testimonial to eliminate trust theatre flags. Provide a high-level summary or link to a profitability report to substantiate the outspoken profit claims.

The site aligns perfectly with the Software, SaaS & Tech Products category, though it functions more as a philosophical hub and catalog for its primary products, Basecamp and HEY. The content explicitly discusses software architecture frameworks like Ruby on Rails and the operational realities of running a long-term SaaS business.

“The score of 9 is driven primarily by technical gaps in Identity and Authority and missing Proof Paths for performance claims. The site is nearly flawless in terms of Information Density and Semantic Coherence, avoiding almost all industry clichés. The trust theatre flag for the unverified review count is a minor technical penalty that does not overshadow the high overall substance.”
