Sabrina Horn and the trouble with making it up

Sabrina Horn took a vacation day to find out whether she had a business. She was 29, had a four-page plan and wanted to build a communications firm serving business software companies. She pitched a startup. By the time she got home, a message was waiting: she had won the account. There are worse ways to spend a day off.

Then she told her parents. They were unconvinced. Without formal business training, they thought, her chances were poor. These were German immigrants whose example had helped give her the appetite to control her own destiny. Now that she proposed doing precisely that, they had reservations. Family encouragement can arrive with some unusually rigorous terms and conditions.

Horn paused, reconsidered the risks and went ahead. In 1991, she founded Horn Group in San Francisco. Her starting money was $500. The company would remain hers to run until its sale to Finn Partners in 2015. Between those dates lay the less photogenic business of becoming an employer, keeping clients, changing services and learning what a CEO actually owes the people listening to her.

A plan can be short. The education takes longer.

Horn had studied American studies at William Smith, graduating in 1983, with a minor in dance. A master’s degree in public relations at Boston University followed. Her work before Horn Group included positions at Edelman and Blanc & Otus in San Francisco. She understood communications. Running an entire company required a considerably broader syllabus.

In a 2025 interview, she recalled the adjustment: “I knew how to write and build a brand,” while the financial and operational work proved challenging. She learned to try people as contractors before committing to full-time hires. An agency founder can know exactly how to explain a client’s company and still have plenty to learn about operating her own.

Her advice to prospective owners consequently includes a household calculation: how much money must come in to keep life going, and where will it come from? It is practical arithmetic for a decision often described in romantic language. Horn had secured a customer before leaving salaried employment. The leap came with a landing place, however small.

That detail matters to her later argument about confidence. Starting something requires acting before every uncertainty has disappeared. It also requires admitting which uncertainties remain. A paying client establishes something a stirring personal manifesto cannot. Horn’s first piece of evidence was already in hand.

The business beyond the press release

The agency grew around technology companies whose products needed explaining. Its work included enterprise software and, over time, a wider range of technology and media businesses. PeopleSoft, Cognos, Novell and Forbes Media appeared among its clients. These were different businesses with different audiences; a single attractive sentence would hardly do all the work.

Horn Group opened its New York office in 2002 and created a digital practice in 2004. Public relations, interactive work and social capabilities could then sit within the same agency. For Horn, building the firm meant paying attention to the channels through which a company actually met its customers, investors, employees and business partners.

The human side of that work remained important to her. In a 2005 interview, she argued that technology should preserve personal contact. Blogging was opening a new route to audiences, but it also created obligations: choosing subjects, maintaining quality and finding time to respond. Even a new publishing tool needed an actual person willing to do the publishing.

Her hiring preferences were similarly concrete. She liked applicants with experience across several forms of communication, rather than a narrow collection of PR credentials. She also looked for humor. Anyone who has endured a meeting about the wording of a sentence can appreciate why this might belong in an employment specification.

Twenty-four years, then a different chair

By September 2015, Horn was ready for a change in ownership. Finn Partners acquired Horn Group, bringing its San Francisco and New York teams into a larger independent agency. Horn became managing partner and U.S. technology practice leader. Her digital team joined Finn’s digital operation; the offices joined its existing regional teams.

The arrangement gave clients access to broader services and gave employees room to develop inside a larger organization. Horn had spent more than two decades attaching her name to a company. The sale required thinking about what would happen to the business after that name stopped being the whole organizational chart.

She moved into a senior adviser role at Finn in 2018. The dates provide a useful corrective to the compressed version of entrepreneurial success, in which a launch is followed almost immediately by an exit. Horn’s independent agency occupied 24 years. The acquisition was a major event within a much longer working life.

Her next work would use the experience differently. At HORN Strategy, she advises founders and executives on early business decisions, leadership, positioning and growth. The services include difficult conversations, board relationships, investor communications and preparing for pivots. These are recognizable founder problems, usually requiring more judgment than ceremony.

An inconvenient position for a publicist

In June 2021, Berrett-Koehler published her book, Make It, Don’t Fake It: Leading with Authenticity for Real Business Success. Geoffrey Moore wrote the foreword. Horn was addressing the little instruction that has enjoyed such a long career in business: fake it till you make it. Its brevity certainly helps it travel.

Her objection is grounded in the obligations of leadership. A founder exaggerating a product’s capabilities creates expectations that somebody must eventually meet. Leaving out material information can distort a decision even when each sentence, taken separately, is true. Reassuring people becomes an expensive habit when the reassurance depends on things that have not happened.

Horn developed a Fake-o-Meter to describe a range of behavior, from practicing confidence to deception and fraud. The distinctions leave room for ordinary human nerves. Rehearsing a presentation does not require inventing the company’s results. A leader can prepare to look composed while being exact about what the business can deliver.

She brings a publicist’s understanding of what happens after a claim leaves the room. Journalists ask questions. Customers try the product. Investors examine the numbers. The audience has activities other than admiring the pitch. For someone whose career involved getting companies heard, she has devoted considerable energy to deciding what they can responsibly say.

The expert who still needs to ask

Horn’s view of thought leadership is demanding in a rather unfashionable way. She expects the executive to believe the argument, understand its purpose and know whom it helps. Producing an article is only part of the job. The company must have something worth contributing, and it must be able to support the claim.

She has described the temptation to turn a promising argument into a committee document containing every available message. Focus disappears. Her response is to return to the point and the intended reader. The usefulness of a piece of writing depends on what another person can do with it, beyond discovering that its author has a job title.

That approach also places a burden on agencies. Specialist technology work requires people who understand the technology and its market. Horn has discussed investing in a cybersecurity writer with that knowledge. Expertise costs money; it also needs enough work to sustain it. A proposal can promise depth rather cheaply. Delivering it requires staffing decisions.

Her shorter advice is easier to carry into a meeting: “Know what you don’t know.” It applies to building a team as much as answering a question. People with complementary abilities expand a leader’s capacity. Hiring a roomful of replicas offers fewer opportunities to discover what the original has missed.

The publicity expert sells one book

Becoming an author supplied an entertaining change of scale. Horn had spent years pursuing agency business. Now she was asking people to buy a book, often one copy at a time. She described learning to appreciate the effort involved in reaching an individual reader. A large professional network does not automatically become a stack of orders.

She also worried about exhausting people with promotion before publication. For the author, a launch can occupy almost every working thought. For someone scrolling past, it might occupy half a minute. Recognizing that difference is an audience lesson with a distinctly personal sting when your own name is on the cover.

In preparing the launch, she described writing individual messages to hundreds of contacts and reconnecting with people she had not spoken to in years. Strategy still required its small errands: sending a biography, supplying a photograph, checking whether a reader had received a review copy. The publicist had become the client, with the accompanying paperwork.

There is more to her than the management argument. She has two daughters, Grace and Christina. Her official biography mentions two large goldendoodles. She has also spoken about enjoying painting. The dance minor, the art and the dogs add some welcome texture to a career that could otherwise be mistaken for an extended sequence of business meetings.

Back where the questions begin

Horn’s relationship with Hobart and William Smith continued after graduation. During a 2016 residency, she visited classes, discussed entrepreneurship and met students individually. The setting suited someone who had learned to manage by doing it. Students could ask about the distance between having an idea and having responsibility for the people executing it.

That connection now includes governance. The colleges’ trustee listing records a term ending in 2029 and committee responsibilities including enrollment management and human resources. In January 2026, the colleges listed Horn among trustees scheduled to offer students career conversations the following month, identifying her as CEO of Horn Strategy and a communications expert, coach, adviser and author.

Teaching and advising give her original experience another use. She wants leaders to make better decisions while building businesses that last. The work includes preparing for trouble before it arrives, seeking experienced counsel and being willing to examine a loss. None of these activities looks especially impressive in a victory photograph. They are easier to appreciate when the victory is delayed.

Return to the vacation day. Horn had a plan, limited money, an account and parents who were asking uncomfortable questions. She proceeded with the information she had. Years later, her advice still leaves room for that decision: investigate the risk, do the work and keep learning. Even a four-page plan can accommodate an honest answer.
