So, you want to build your MVP, launch it, and get users and feedback so you can start iterating. But you don't have the skills to build it yourself. So all you need is a developer to help you build it, right? Not quite. Building a good product, even an MVP, requires multiple skillsets. Here we list out some of the experts you need and why.

Finding the Right People

Here are the main roles you may need to successfully shape your MVP:

Product Manager

The Product Manager asks the why and how. They understand your customers, and the company's overall strategy and goals. They bring cross-functional experience, handle product planning and marketing, and know how to define a solid roadmap. You can find one through recruiters, hire one as a contractor, or lure them in as a permanent employee.

Chief Technology Officer (CTO)

The CTO is your token "tech guy" and then some. They are either your co-founder or your hired right-hand person. They might be a front-end developer, back-end developer, mobile developer, or part-time dev ops person. Either way, they have hands-on technical experience plus the vision and drive to lead the charge for your perfect MVP. Find a fitting one through recruiters, on AngelList, Founders Nation, or via trusted peers.

UX Designer/Researcher

The UX Designer, or Researcher, uncovers user behaviors and needs to better guide a product's user experience and design. They collect data, present insights, and impact strategy to improve product definition and drive business goals. Browse through Dribbble or Behance to find one that fits your needs.

UI Designer

The UI Designer takes into account the UX Researcher's findings to determine user requirements and design graphic elements, such as wireframes, storyboards, and user flows. They work with Product Managers and Engineers to create a visually-pleasing and user-friendly product. Dribbble and Behance are great resources for filling this role too.

Software Engineers

The Software Engineer is responsible for building the technical architecture of the product. They bring in-depth knowledge of programming languages, software development frameworks, and tools. They work closely with the CTO and other team members to ensure the technical feasibility of the product.

QA Testers

To ensure your product is fit for release, you'll need to hire a Software Tester. Their mission is to click on every button, perform every task, and test every process to ensure your MVP works flawlessly. They are your one-person Quality Control team, and the final line to mitigating your implementation risk.

Project Manager

The Project Manager asks the what and the when. They ensure tasks are optimally assigned so that everyone is kept busy and motivated, and things are delivered on time and on budget. They are a jack-of-all-trades and exhibit great creativity when finding solutions. Similarly to the Product Manager, you can hire a Project Manager through recruiters, either as contractors or full-time employees.

Ideal resourcing

When it comes to the ideal composition of the team, different roles require different levels of involvement:

  • UX/UI Designer: Needed for a short period at the start of the project, 2-4 weeks.
  • QA Tester: Needed for the last month of the project.
  • Project Manager: Needed part-time throughout the project.
  • Software Engineer: Needed throughout the project.
  • CTO: Needed part-time overlooking the project and more time at the beginning to make architectural decisions.
  • Product Manager: Needed throughout the project.

1 - Prioritise new features / Address User Drop-Off

When you're running a SaaS company, deciding which features to roll out next can make or break your product's appeal. Additionally, understanding why users leave your SaaS platform can be as important as attracting them in the first place. By keeping an eye on KPIs like Churn Rate and Engagement Rate, you gain invaluable insights into what keeps users satisfied and what might be pushing them away. Let's look into some crucial KPIs which can guide you in making well-informed decisions about your next big feature update:

1. Feature Conversion Funnel:

This KPI measures how effectively users move from initial engagement to full use of a feature. It helps SaaS companies identify where users drop off, guiding improvements to enhance feature adoption and prioritising development efforts.

You can use the following formula to calculate this KPI:

Formula for calculating the conversion rate from Stage A to Stage B, defined as the number of users moving from Stage A to Stage B divided by the total users as Stage A.

2. User Engagement Rate:

For SaaS companies, engagement rate measures how actively users are interacting with the application. High engagement rates are often indicative of a valuable and sticky product, reducing the likelihood of user drop-off.

The calculation for this KPI can be done using this formula:

Formula for calculating user retention of a feature, based on the ratio of users still engaged with the feature after a specific period.

3. Customer Satisfaction:

This KPI measures how satisfied customers are with a product or feature, typically through surveys. High satisfaction rates correlate with lower churn and higher loyalty, making it essential for evaluating user experience and identifying areas for improvement in SaaS offerings.

The calculation for this KPI can be done using this formula:

Calculation of Net Promoter Score, subtracting the percentage of detractors from the percentage of promoters among surveyed customers.

2 - Accelerate User Growth

Growing a user base is one of the most exciting challenges in the SaaS world. It's not just about bringing in new sign-ups but ensuring they stick around and find real value in your product. We'll delve into effective SaaS KPIs like Monthly Active Users and the Growth Rate of New Signups that can help you craft strategies to not only attract more users but also engage them deeply:

1. Customer Acquisition Cost (CAC)

The CAC is a crucial KPI for SaaS companies, as it quantifies the cost involved in acquiring new customers. Understanding this metric is essential for evaluating the effectiveness of your marketing strategies and ensuring sustainable growth by maintaining a balance between expenditure and incoming revenue.

To find this KPI, use this formula:

Calculation of Customer Acquisition Cost, total marketing expenses divided by the number of new customers acquired.

2. Growth Rate of New Signups

This KPI tracks the percentage increase in user signups over a given period. It's particularly useful for SaaS businesses to monitor momentum in market penetration and user interest, helping to direct marketing efforts and product development.

This formula is used to calculate the KPI:

Calculation of Customer Acquisition Cost, total marketing expenses divided by the number of new customers acquired.

3. Monthly Active Users (MAU)

In the SaaS world, the MAU KPI measures the number of unique users who interact with your software within a month. This metric is vital as it indicates the active reach of your product and helps gauge the overall stickiness and appeal of your platform.

The following formula can be used to calculate this KPI:

3 - Provide Product Metrics to Investors

Communicating effectively with investors is crucial for any SaaS business. Clear and precise metrics like Monthly Recurring Revenue (MRR) and Churn Rate not only showcase the financial health of your company but also reassure investors about the scalability and stability of your business model. Let's walk through the vital KPIs that paint a transparent picture of your SaaS company's performance for its stakeholders:

1. Monthly Recurring Revenue (MRR)

MRR is a key financial metric for any SaaS business, reflecting the total predictable revenue generated from customers every month. It's essential for investors as it provides a clear picture of the company’s financial health and growth potential.

Here’s the formula to calculate this KPI:

2. Churn Rate

Churn rate is an indispensable KPI for SaaS companies, indicating the percentage of customers who discontinue their subscriptions within a specific period. A lower churn rate suggests a higher customer satisfaction and product-market fit, which is critical for long-term success.

This is the formula for calculating the KPI:

Formula for calculating churn rate, represented as the percentage of customers lost over a specific time frame.

3. Lifetime Value (LTV)

LTV measures the total revenue a SaaS company can expect from a single customer throughout their relationship. This KPI is crucial for understanding how much a company should invest in acquiring customers and for determining the profitability of long-term business strategies.

Use this formula to find the KPI:

4 - Optimise Revenue Generation / Monetisation

Turning your SaaS platform into a robust revenue-generating machine requires more than just great software; it needs a smart monetisation strategy. By focusing on KPIs like Average Revenue Per User (ARPU) and Conversion Rates from Free to Paid, you can really dial in on what makes your users upgrade and how to boost your overall profitability. Let’s break down these KPIs and explore how you can use them to fine-tune your monetisation efforts for maximum impact:

1. Average Revenue Per User (ARPU)

ARPU is a critical financial KPI for SaaS businesses, measuring the revenue generated per user. It helps in assessing the revenue impact of different operational strategies and in fine-tuning pricing models.

Here's the formula you need to calculate this KPI:

5 - Improve Business Resource Allocation and Strategy

Ensuring sustainable business growth and operational efficiency is paramount for any SaaS business. Key performance indicators (KPIs), such as the LTV:CAC ratio, provide a clear picture into the returns generated and optimal resource distribution. Let's dive into the KPIs that will help you strategically allocate resources, adjust marketing strategies, and effectively balance customer acquisition with retention:

1. Customer Lifetime Value to Customer Acquisition Cost Ratio (LTV:CAC)

The LTV:CAC ratio is a vital KPI in the SaaS industry, providing insight into the relationship between the lifetime value of a customer and the cost to acquire them. A healthy ratio indicates that a company is spending efficiently on customer acquisition while maximising revenue from each customer. The bigger the multiple, the more budget you can put into growing a team and customer growth.

To find the KPI, apply the following formula:

Formula showing the ratio of Lifetime Value (LTV) to Customer Acquisition Cost (CAC), a key indicator of the profitability of acquiring new customers.

2. Customer Acquisition Cost Payback Period

The Customer Acquisition Cost (CAC) Payback Period is a critical metric for SaaS businesses. It measures how long it takes to recover the costs of acquiring new customers, helping companies evaluate the efficiency of their marketing and sales efforts. A shorter payback period means a quicker return on investment, guiding better financial and strategic decisions.

This formula will help you calculate the KPI:

Formula to determine the payback period for customer acquisition costs, calculated by dividing CAC by monthly profits from a customer.

3. Market Penetration Rate

The Market Penetration Rate is essential for understanding a SaaS company's market impact. It measures the percentage of the total addressable market that the company has captured. This metric helps assess competitive position and growth opportunities, indicating how well the product is adopted in the market.

Use this method to calculate the KPI:

In wrapping up, it's clear that understanding and using KPIs effectively is vital for any SaaS business that wants to grow and thrive. By focusing on key metrics like Customer Acquisition Cost (CAC), Annual Recurring Revenue (ARR), and Lifetime Value (LTV), you can get a clear picture of how your business is doing and where you need to go. These KPIs aren't just numbers—they're powerful tools that help you and your team make smart decisions and reach your goals.
