In 2003, Sam Michelson was not trying to invent an industry. He was trying to sell internet phone service. Vonage had made home VoIP feel viable, and the web had supplied two wonderfully blunt instruments for finding customers: Yahoo’s Overture and Google AdWords. Michelson bought attention, built landing pages and kept a phone line open six days a week for people who wanted help placing an order. The work was commercial, direct and measurable. A click either became a customer or it did not.
The experiment expanded to mobile-phone plans from T-Mobile, Verizon, Cingular, Nextel and Sprint. Then, in 2004, curiosity pulled him sideways. Michelson searched for the most expensive keyword on Google and found “mesothelioma,” with clicks that he remembers costing more than $60. He and a friend built a small tool called KeywordsFinder, which generated misspellings that advertising platforms did not yet correct automatically. They sold a few dozen copies, tested the overlooked spellings themselves and found traffic at a fraction of the standard price.
A lawyer needed those leads. The relationship lasted years. An e-commerce operation gradually became a consultancy, and the useful thing hiding behind the original product revealed itself: Michelson was less interested in what people bought than in how the screen shaped what they believed.
A company name left over from the family
Five Blocks sounds as if it ought to contain a theory. It does not. Michelson and his siblings had used the domain for online projects in the late 1990s and early 2000s. When he established the company, he took over the name. No acronym, no pentagonal brand mythology, no origin story polished by committee. The name was available and already belonged to the family’s digital past, so it stayed.
The business did acquire a theory. Search was becoming the lobby through which everyone entered a company. A journalist, investor, recruit or customer might know the official web address and still begin with Google. The results page arranged corporate history without asking permission. An old controversy could sit beside a new product; a thin Wikipedia page could outrank years of careful work; a stranger’s description could become the first paragraph of an introduction.
“Your reputation is what Google says it is.”Sam Michelson, writing in 2010
That sentence is deliberately provocative, but the operating idea is subtler. Search does not contain the whole truth about a person or business. It contains what has been published, indexed, weighted and retrieved. Yet the incomplete version can still govern the next decision. Five Blocks built services and software around that gap, working with communications teams on search results, corporate sites, earned coverage, profiles and Wikipedia.
Psychology with a patent drawer
Michelson studied psychology at Yeshiva University, then management at Boston University. That pairing feels almost suspiciously tidy in retrospect. Reputation sits where systems meet judgment: software arranges the evidence, but a human being decides what the arrangement means. His own career kept both sides in view.
He is named as an inventor on two U.S. patents. One concerns tools for training and testing a knowledge base through text categorization. The other covers advertising in an end-user-controlled playback system. Neither patent makes him a laboratory technologist in the popular founder mold. They do show a recurring interest in organizing information, measuring how a system behaves and improving the machinery behind an experience.
The company’s growth was not a single rocket-shaped event. Its Inc. 5000 appearances came in two runs: 2014 through 2016, then 2020 through 2023. By the last of those listings, the firm was described as having 51 to 200 employees. The pattern suggests an operator prepared to revisit the work after the novelty has left the room, which is where most businesses actually live.

Sailing lessons for constrained companies
Michelson’s explanations tend to begin somewhere away from a conference table. In eighth grade, while living in Brookline, Massachusetts, he and his brother spent a summer at Community Boating. One exercise taught students to steer without a rudder. Shift the passengers. Tighten the main sail and jib. Learn the forces well enough to change direction after losing the obvious control.
Years later, he used the lesson to describe reputation work for banks, insurers, pharmaceutical companies and other regulated businesses. Such clients cannot always publish freely or respond in the style a consultant might prefer. The missing rudder requires better use of the remaining system. Constraints, in Michelson’s telling, are not romantic. They simply make lazy technique unavailable.
“And we keep sailing, with or without a rudder!”Sam Michelson
The same pattern appears throughout his personal writing. He watched children scramble for sweets after a bar mitzvah and sorted their choices into miniature business strategies: arrive early, choose the crowded center, work the less competitive edge, invent a better catching device, share the winnings. He took a week-long scuba course in Eilat because it was an adventure his teenage sons would accept. On his about page, he catalogued ideas he had not built, including mirrored sunglass contact lenses, glow-in-the-dark plants and an ambient information display for the shower.
There is play in all of this, but also method. Michelson notices how people act inside a system. His public persona is less oracle than inveterate noticer, the person at the edge of the room quietly turning a candy scramble into a market map. It helps explain why a psychology graduate was drawn to search data. Algorithms are interesting; behavior under their influence is better.
When the list became a paragraph
For most of Five Blocks’ life, the visible object was a ranked page of links. The communications task was to understand which results appeared, why they appeared and what a searcher would infer from the mix. Generative AI changed the shape of that object. The list became a paragraph. The searcher no longer needed to assemble a narrative because the machine volunteered one.
How a scattered footprint becomes a single answer
Michelson argues that public relations now has a fifth category beside paid, earned, shared and owned media: synthesized narrative. It is not written by a company, purchased as placement, passed through one journalist or distributed by a social graph. An AI assembles it in real time from material that may have been created for entirely different purposes.
His concern is often not a spectacular hallucination. It is a vacuum. Companies publish their strengths but leave difficult subjects to everyone else. They maintain a sparse executive biography, an old conference page or a neglected corporate history, then discover that an AI has confidently knitted those scraps together. In a 2025 interview, Michelson’s advice was to create rich, authoritative material that addresses what users genuinely ask, including awkward questions. Silence does not keep a subject out of the answer. It merely surrenders the source selection.
Five Blocks tested its response internally for about a year, then publicly launched AIQ in March 2026. The platform monitors how eight systems, including ChatGPT, Gemini, Claude, Perplexity, Grok and Google’s AI products, describe a brand. It looks beyond mention counts to themes, sentiment and the sources influencing each model. For Michelson, visibility without context is a misleading comfort. A company can appear often and still dislike the sentence in which it appears.

The founder becomes his own test query
There is a pleasing circularity to Michelson’s latest experiment. In September 2026, he typed “Tell me about Sam Michelson” into Google’s AI Mode and examined the result. The consultant who asks organizations to inspect their machine-made reflection had turned the glass toward himself.
His career had begun with a very different search box. In 2004, he asked which keyword cost the most because he wanted to find an opportunity hiding at the edge of an advertising market. Now he asks what an AI knows about him because the answer itself has become the market, the reputation and sometimes the introduction.
The interesting continuity is not that Michelson predicted every turn. He did not need to. He followed a durable curiosity from one interface to the next. What do people see? Why do they see it? What will they believe after they do? The internet grew from a list of links into a machine that speaks in complete sentences. Michelson is still reading the screen closely, watching for the part everyone else forgot to type.
