Product/Market Fit is not the Holy Grail
It all begins with an idea.

Product<>Market fit is not the holy grail.
We often obsess over Product <> Market Fit (PMF), but it’s only one piece of a larger puzzle.
PMF doesn’t guarantee a successful monetization model or channels fitting your unit economics.
The 4-Fits Framework, introduced by Brian Balfour in 2017, gives a more complete view of what a company needs to solve to scale to $100M+ 👇
1️⃣ 𝗠𝗮𝗿𝗸𝗲𝘁 < > 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗙𝗶𝘁
Your product must solve a real problem for a specific market.
Instead of talking about Product<>Market Fit, Brian describes it the other way around: Market first, product then.
○ Identify the needs of your target audience: Research your potential customers’ pain points and behaviors.
○ Hypothesize: Align your product with market needs to solve your audience's problems. Formulate hypotheses around core value propositions, hooks, and retention mechanisms.
○ Validate: Measure engagement and retention rates. Flattening retention curves indicate consistent value delivering, a key Market-Product Fit indicator.
2️⃣ 𝗠𝗼𝗱𝗲𝗹 < > 𝗠𝗮𝗿𝗸𝗲𝘁 𝗙𝗶𝘁
Align your business model with the market’s willingness to pay and size.
○ Understand Economics: Calculate your Average Revenue Per User (ARPU) to ensure it aligns with market willingness to pay.
○ Design Revenue Streams: Develop a pricing strategy that fits market purchasing behavior. This could include subscriptions, freemium, or tiered pricing.
○ Monitor Unit Economics: Track CAC, Payback Period, and LTV to ensure a healthy balance. Aim for a CAC that is recoverable within a reasonable timeframe relative to the LTV.
3️⃣ 𝗖𝗵𝗮𝗻𝗻𝗲𝗹 < > 𝗠𝗼𝗱𝗲𝗹 𝗙𝗶𝘁
Find scalable channels, adapted to your model, to reach your target customers.
○ Identify Channels fitting your model: A high ARPU allows high CAC channels like Events. A low ARPU suggests channels like Social Media or Ads.
○ Optimize Channels Efficiency: Ensure chosen channels provide sustainable CAC. Evaluate the scalability of each channel to handle increasing volumes.
○ Align with your audience behaviors: Different industries use different channels. Go where your audience spends time.
4️⃣ 𝗣𝗿𝗼𝗱𝘂𝗰𝘁 < > 𝗖𝗵𝗮𝗻𝗻𝗲𝗹 𝗙𝗶𝘁
One or two channels generally drive >70% of your Growth (sometimes even more in the early days). Your product should fit important distribution channels.
○ Build Channel-Specific Features: For virality for example, include features like collaboration, a low-friction sign-up flow, and a referral program.
○ Prioritize channels based on your product: Channels should not have to adapt to your product.
○ Ensure a seamless technical integration: Compatibility with platform APIs or having a mobile-responsive flow might be crucial in some cases.
Each of these fits addresses a part of a large Growth Equation. This goes beyond the focus on Product <> Market Fit alone.

Due diligence is more than just a formality—it’s the key to making informed startup investments that protect your capital and future returns.
Many investors dive into exciting startup opportunities without fully evaluating the risks.
But neglecting a thorough review of key areas can expose you to unforeseen legal and business pitfalls.
What often happens is that investors overlook crucial elements in the due diligence process, focusing too much on the product and less on underlying risks.
This can lead to missteps that affect both their investment and the startup's future.
The truth is, conducting proper due diligence helps you uncover potential issues early on, providing clarity on the risks and helping you make better investment decisions.
Are you conducting thorough due diligence before making startup investments?
Here’s a checklist of key areas investors should focus on when evaluating a potential startup investment:
