Title: Product/market fit
Content:  Product/market fit, also known as product-market fit, is the degree to which a product satisfies a strong market demand. Product/market fit has been identified as a first step to building a successful venture in which the company meets early adopters, gathers feedback and gauges interest in its product(s).
Title: Product/market fit
Content:  Product/market fit might be interpreted in terms of Alexander Osterwalder's Business Model Canvas paradigm as comprising value proposition, customer segment, relationship, and channel. Achieving Product/market fit implies these are set without requiring additional changes or pivots.
Title: Product/market fit
Content:  According to Benchmark Capital co-founder Andy Rachleff, Sequoia Capital founder Don Valentine created the concept of product-market fit. Venture capitalist Marc Andreessen of Andreessen Horowitz would later popularize the term in the mid-2000's. Andreesen credits Rachleff for the concept, referring to the idea as Rachleff's Corollary of Startup Success: "The only thing that matters is getting to product/market fit." Marc Andreessen defined the term as follows: “Product/market fit means being in a good market with a product that can satisfy that market.” Many people interpret product/market fit as creating a so called minimum viable product that addresses and solves a problem or need that exists. Steve Blank referred to the concept of product/market fit as a step in between customer validation (step #2 in his book The Four Steps to the Epiphany) and customer creation (step #3).
Title: Product/market fit
Content:  It is important to differentiate between product/market fit and problem/solution fit when measuring a company's customer base. More specifically, when gauging a customer's desire, companies need to be sure they are measuring desire for the product or service—not just for a solution. Misinterpreting customers' desire for a solution as desire for a company's product or service will end up being a false positive for product/market fit. Product/market fit is not binary. For a fledgling startup, a minimum degree of product/market fit will not be adequate in order to achieve market traction and success. Rather, what is actually required is a high degree of product/market fit, or extreme product/market fit.
Title: Product/market fit
Content:  There are five metrics any online business can measure to empirically verify if they achieved Product / Market fit. They are 1. Bounce Rate, 2. Time on Site, 3. Pages per Visit, 4. Returning Visitors, 5. Customer Lifetime Value. Low bounce rates means a visitor's expectation is being met. High Time on Site and Pages per Visit indicate that the experience of the user is satisfactory. High Returning Visitor reflects the lasting impact a product has on their customers, causing them to come back, and Customer Lifetime Value measures the profitability each customer brings to the company. If these 5 metrics are above average and your 40% rule is met, you'll know you have a Product / Market Fit company.
Title: Product/market fit
Content:  One metric for product/market fit is if at least 40% percent of surveyed customers indicate that they would be "very disappointed" if they no longer have access to a particular product or service. Alternatively, it could be measured by having at least 40% of surveyed customers considering the product or service as "must have". Sean Ellis is noted for popularizing this heuristic after examining many startups. Rahul Vohra of Superhuman has developed a survey-based model based on the 40% Rule to help post-launch startups test and optimize for this metric.
Title: Niche market
Content:  A niche market is the subset of the market on which a specific product is focused. The market niche defines the product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that it is intended to target. It is also a small market segment. Sometimes, a product or service can be entirely designed to satisfy a niche market. Not every product can be defined by its market niche. The niche market is highly specialized, and aiming to survive among the competition from numerous super companies. Even established companies create products for different niches; Hewlett-Packard has all-in-one machines for printing, scanning and faxing targeted for the home office niche, while at the same time having separate machines with one of these functions for big businesses.

How will customers view your product in the marketplace? "The organisation's marketing task is to determine the needs, wants and interests of target markets and to achieve the desired results more effectively and efficiently than competitors, in a way that preserves or enhances the consumer's or society's well-being." ; Positioning - How does the company plan to position its product in the market? Different factors will need to be considered when you position your product in the marketplace as it will impact on consumer's perceptions about your product and brand. For example, how you will price the product and the quality of it. 
Title: Product marketing
Content:  Product marketing is a strategic marketing function that bridges the gap between product management and marketing communications. The primary role of a product marketing manager is to define and size target markets and value propositions. Other critical responsibilities include positioning and sales enablement. Product management deals with the basics of product development within a firm, whereas product marketing deals with marketing the product to prospects, customers, and others. Product marketing, as a job function within a firm, also differs from other marketing jobs such as social media marketing, marketing communications ("marcom"), online marketing, advertising, marketing strategy, and public relations, although product marketers may use channels such as online for outbound marketing for their product. A product market is something that is referred to when pitching a new product to the general public. Product market definition focuses on a narrow statement: the product type, customer needs (functional needs), customer type, and geographic area.
Title: Core product
Content:  Product marketing is the process of promoting and selling a product to an audience. It further includes defining the scope of the product line, identifying potential markets for a product and determining optimal pricing. Product Marketers also act as a bridge between Sales, Marketing and Product, reporting on the market's response to product launches and updates in order to refine messaging and features. As mentioned, the core product directly affects customers' interest level.
