Your minimal viable product (MVP) has proven that your solution works. Now it’s time for the growth phase — the decisive phase in which you make the solution marketable, win new customers and take your startup to the next level.
You’ve come to the right place if …
- you have founded an impact startup.
- your target group, the problem and the impact of your solution are clearly defined.
- your MVP has been tested and validated.
- the impact and market potential as well as the financing model.
- the necessary resources are available.

Making your MVP marketable
Now it’s all about turning your MVP into a convincing offer for the market.
1. optimize your solution
- Complete the functions: Ensure that all core functions of your solution also work perfectly outside the test environment.
- Increase efficiency: Make the provision of your solution or the cost of your service more efficient. Bear in mind that this is not always possible, especially with labor-intensive offerings.
- Check scalability: Your technical infrastructure should be robust enough to grow with increasing demand.
2. further develop the MVP
Based on the feedback and usage behavior of the MVP testers (see chapter “Minimal Viable Product on the test bench: Testing the impact of an impact startup”), you can now further optimize the user experience. Carry out regular user tests to ensure that new features meet expectations. This will minimize the risk of misdevelopment.
Tip
Create a release plan that prioritizes the most important functions for future versions of the solution. Focus on the elements that offer the greatest added value for your target group.
3. expand your team
Expand your product development team and involve experts from areas such as UX/UI design, product management and marketing (see chapter “Sustainable growth for impact start-ups: team, structure and culture”).
From early adopters to a broad customer base
Growing means tapping into a larger share of your target and customer groups and requires a well thought-out strategy. These 5 steps will help you:
Target group vs. customers
In the Lean Impact Journey we differentiate between the target group when we deal with the impact model and the product and customers when it comes to the business model.
How you use these two terms for your project depends on what your solution consists of. In this playbook, the target group is defined as people who use the solution and those who benefit from the solution.
Depending on the solution, the target group can combine both.
1. prioritize certain functions of your solution
For the time being, limit yourself to developing elements that offer the greatest added value for your target and customer group. Expand the scope only gradually around the core of the solution.
2. improves user-friendliness
Continuously improve the usability, design and layout of your solution. Use user-centered design methods to optimize your target and customer group’s experience with the solution.
3. increase your customer base
Expand your customer base beyond the early adopters. We recommend the following distribution to start with:
- Innovators (3%): Innovation enthusiasts who are the first to try out new solutions.
- Early adopters (13%): Visionaries who recognize the value of your solution early on.
- Early Majority (34%): Pragmatists who are looking for proven solutions.
- Late Majority (34%): Conservatives who only get on board when there is broad acceptance.
- Latecomers (16%): Skeptics who are reluctant to accept new solutions

4. develops target and customer-specific strategies
Adapt your approach depending on the target and customer group. For example, you can emphasize the power of innovation and your vision for the solution when communicating with innovators and early adopters. If you are addressing the early majority, focus on practicality and proven use cases. The best way to convince the late majority is to demonstrate the broad market acceptance of your solution and minimize risks. Present your solution to the latecomers as an established standard.
5. uses success stories
Tell stories about early adopters to convince other customers with these references.
Establish marketing and sales channels
Nothing works without visibility and a solid sales system. This is how you expand both in a targeted manner:
1. analyzes the initial situation
First of all, you should collect as much data as possible about your potential customers: Gather market data, do a competitive analysis find out which channels other startups in your industry are using successfully and analyze your performance data. Use tools such as Google Analytics, social media dashboards or customer surveys to evaluate your activities to date.
A SWOT analysis then helps you to strategically evaluate your existing marketing and sales channels:
- Identify strengths: What makes your marketing and sales channels already successful (e.g. high visibility through social media and SEO, high conversion rates)?
- Identify weaknesses (Weaknesses): Finds out where there is a need for optimization (e.g. unclear target or customer group approach, no capacity for campaigns).
- Identify opportunities: Think about external factors that you can use for your growth (e.g. new trends such as sustainable marketing, cooperations).
- Recognize risks (threats): Recognizes which challenges or risks could jeopardize the solution. These could be competing solutions, a lack of resources or negative trends that make implementation more difficult.
Then define goals for your marketing and sales strategy using the S.M.A.R.T. method. The indicators should
- Specific: clearly defined and unambiguous
- Measurable: Quantifiable
- Attractive: relevant for your goal
- Realistic: achievable with available resources
- Scheduled: limited in time
be.
2. determine your customer group
Create detailed profiles of your customers that include their pain points and needs. You have already created the basis for this in the chapter “Problem and target group analysis: how to validate for impact start-ups”. You can use personas or the leaner version of the value proposition canvas for this.
Target group vs. customers
In the Lean Impact Journey we differentiate between the target group when we deal with the impact model and the product and customers when it comes to the business model.
How you use these two terms for your project depends on what your solution consists of. In this playbook, the target group is defined as people who use the solution and those who benefit from the solution.
Depending on the solution, the target group can combine both.
3. further develop your Unique Selling Proposition (USP)
The USP shows what makes your solution unique and why customers should choose your offer. The tool Lean Canvas tool helps you to formulate clear sales arguments. For early phases, you should emphasize revolutionary aspects and visions; for later phases, focus on reliability and broad acceptance.
How to use the Lean Canvas to sharpen your USP:
- Problem: What is the customer’s main problem? Your USP should answer this directly.
- Customer segments: Who are your customers and why is your offer tailored to their needs?
- Unique value proposition (UVP): Formulate concisely why your solution is special. For example: “Faster, more sustainable, more efficient.”
- Channels: How and where do you communicate your USP most effectively (e.g. through content marketing, social media or testimonials)?
- Unfair advantage: What makes your USP difficult to copy? For example, an exclusive technology, special expertise or a strong network?
4. selects suitable marketing channels and methods
In the next step, it is important to optimize existing marketing processes. Creating a SIPOC diagram can help you do this. We explain how to do this in the previous chapter “Sustainable growth for impact start-ups: team, structure and culture”.
Marketing methods that you can use:
- Content marketing to provide valuable content
- Social selling through social networks for reach and engagement
- SEO to improve online visibility
- Referral marketing by motivating satisfied customers to recommend your solution to others
5. select suitable distribution channels
You can then develop a multichannel strategy consisting of different sales channels — both online and offline. You should also optimize existing sales processes. Once again, creating a SIPOC diagram can help with this (see previous chapter “Sustainable growth for impact start-ups: team, structure and culture”).
Typical distribution channels are:
- Direct sales channels such as physical retail (stationary sales), e‑mail marketing, e‑commerce
- Indirect sales channels such as partnerships with other companies, wholesale, franchise
- Modern digital sales channels such as mobile apps, webinars and online training, content marketing (blogs, videos, podcasts)
6. train your marketing and sales team
All strategies are useless if you don’t get the relevant team on board. Therefore, conduct regular marketing and sales training sessions. You can find out how to identify existing knowledge gaps and develop further development measures in the chapter “Sustainable growth for impact start-ups: team, structure and culture”.
Develop different growth scenarios
Future viability means not only planning the ideal case, but also thinking through all possible developments with foresight. This is how you develop well-founded growth scenarios:
1. analyze the historical growth of your startup
In order to create realistic forecasts, you should first analyze your previous growth rates. To do this, look at your turnover in recent years and compare the development with relevant industry benchmarks and competitors. Also consider whether your growth has had a greater impact at the same time.
Example: A technology start-up has had an annual growth rate of 20 percent over the last three years. This historical trend forms the basis for the forecasts.
You can also use key figures such as the compound annual growth rate (CAGR), the sales growth rate or the customer growth rate to get a clear picture. The formula for the sales growth rate is:
(Turnover of the current year — turnover of the previous year) / turnover of the previous year × 100.
2. consider external factors that can influence your growth
In addition to internal data, it is important to take external influences into account. With a top-down approach, you can analyze macroeconomic factors such as industry trends, GDP growth or regulatory requirements. The bottom-up approach, on the other hand, starts with specific company data, such as your market share or turnover, and builds on this.
Expert opinions, management strategies and market sentiment can help you to assess opportunities and risks.
By analyzing market and impact trends and untapped markets, you can identify expansion opportunities.
3. develops concrete growth scenarios
You can use the collected data to run through various scenarios for the future:
- Best-case scenario: Imagine that everything goes perfectly. Your solution is quickly accepted, financing rounds are successful, the actual impact exceeds your expectations and your growth reaches a new level. Assume, for example, that turnover exceeds expectations by 50% or that you gain significantly more customers than planned.
- Base case scenario: Base your plans on average developments and historical data. Accordingly, you plan for steady growth, stable income and controlled expenses — your projects run as planned and most customers pay on time.
- Worst-case scenario: Here you assume the worst possible case. This could include a slow product launch, delays in financing rounds, a lack of impact or an unfavorable market development. The result would be a slump in business.
Examples: Assume that payments from customers are severely delayed, projects cannot be fully invoiced or sales efforts fail.
4. derives measures from the scenarios
You can then develop strategies to maximize the opportunities in the best-case scenario, secure the base-case scenario as a solid foundation and minimize the risks in the worst-case scenario. This allows you to remain flexible, react at an early stage and manage your growth in a targeted manner.
Next step: Measure KPIs
An important step has been taken: you have started to make your startup economically fit for the growth phase!
Before you move on to measuring KPIs and creating a reference scenario, you should also prepare your team, your structures and your organizational culture for the growth phase (chapter “Sustainable growth for impact start-ups: team, processes and culture”) and optimize your impact management (LINK 2).
