It’s still popular these days for startup founders to operate in stealth mode, meaning no details about the idea or progress are shared with anyone until the big reveal and rollout. The common reason given is that this prevents any competitor from stealing their idea and beating them to market. In my view, this paranoid approach costs them much more than the risk of being open.

I’m not suggesting that a startup should ever disclose patent details to others before filing, but I can’t imagine why a startup would not seek visibility and feedback for their idea and solution while they could still make changes with minimal cost. Pivots and corrections are inevitable for startups in this age of rapid change, and the earlier you make them, the quicker you get to success.

Being open is the new business culture around the world. Entrepreneurs talk to customers and competitors talk to each other about the new trends and technologies they see. Coopetition is the new mantra for growing your business faster. Here are seven key reasons that being open is better for your startup than trying to fly under the radar:

1. Visibility generates interest. You can’t get any word-of-mouth or media activity by hiding. Before you finalize the product is the best time to talk about it and see if you can get some buzz started. This will do more for your first mover advantage than more time in the lab. Most people agree that even negative media attention is better than none.

2. Evaluate customer response prior to development. It’s never too early to get real feedback from the people who count. No matter how passionate and certain you are that your idea is perfect, the reality is that you will likely need to pivot at least once. Why not make the change before you have wasted significant time and money?

3. Get competitors to surface early. You may be convinced that no competitors exist, which is very unlikely. If there really are no competitors, then there is likely no market opportunity, or you haven’t looked yet. If your position is so tentative that knowledge of your idea puts you in jeopardy, you need to know it sooner, rather than later.

4. Demonstrate a minimum viable product (MVP). Surface your prototype, get customer feedback, make corrections, and iterate until you get it right. Startups in stealth mode often have a false sense of security that they can take extra time to do the job right the first time. Customer feedback is required to get it right, and hidden time is wasted time.

5. Meet investors before asking for money. The time to build investor relationships is before you need the investment. It gives you credibility to mention your idea in general terms, without immediately asking for money. This can help you get in the door when you are ready, and asking questions early will give you insights on investor priorities.

6. Pivots can be done gracefully at this point. Customer credibility actually improves when they see you making changes based on their input, and the cost of correcting mistakes early is lower. Operating in stealth mode for an extended period tends to convince entrepreneurs to believe their own biases, and visibly fight the need to change.

7. Optimize your web history and presence. Stealth mode normally means no time for search engine optimization prior to product launch, not to mention relevant blogging activity, and link building. This means your whole startup effort will appear as very early stage for investors, and will likely not be adequately tuned for customers.

On the other hand, stealth mode does make sense for large companies, like Apple and IBM, who will likely be sued for pre-announcing a future product, since other companies have used this ploy in the past to freeze the market and lock out new competitors. Of course, even startups can get into serious trouble by talking about products and direction with no intent or ability to deliver.

I also realize that there are a limited set of startups, facing particularly entrenched and unscrupulous competitors, where early stealth mode is necessary. With most other classes of startups today, including smartphone apps, web services, and social media applications, early customer feedback is critical, and time to market is of the essence, so secrecy is more of an excuse than an advantage. Who are you fooling by not allowing your startup to be found?
