In 2026, the conversation is more nuanced. Higher interest rates, tougher fundraising conditions and rising acquisition costs have exposed what many founders and investors already suspected: a SaaS business is not automatically a good business.\n\nIn this article, I take a step back and analyse, in a pragmatic way, whether SaaS models are still viable in 2026\u2014and under what conditions. I focus on the underlying economics: ARR, MRR, ARPU, churn, CAC, LTV and CAC payback. Without these basics under control, adding AI or any other buzzword on top of your product simply amplifies the problem.\n\nThe goal is not to repeat textbook definitions, but to show how these metrics interact in a realistic P&amp;L, using a simple numerical example that any founder or investor can adapt to their own context.\n<div class=\"saas-toc\">\n<h3>\ud83d\udcd8 Article index<\/h3>\n<ul>\n\t<li><a href=\"#sec1\">1.

The challenge is that this stability is the result of a fairly delicate balance of variables.\n<h3>1.1 <strong>From MRR to ARR: more than just multiplying by 12<\/strong><\/h3>\nTwo metrics dominate most SaaS dashboards:\n<ul>\n\t<li><strong>MRR (Monthly Recurring Revenue)<\/strong>: recurring revenue in a given month.<\/li>\n\t<li><strong>ARR (Annual Recurring Revenue)<\/strong>: often approximated as MRR \u00d7 12.<\/li>\n<\/ul>\nOn paper, ARR is just MRR multiplied by 12. In practice, ARR is more than a number; it is a proxy for:\n<ul>\n\t<li>The <strong>size<\/strong> of the business in recurring terms.<\/li>\n\t<li>The <strong>future revenue base<\/strong> you can reasonably expect, assuming churn is under control.<\/li>\n\t<li>The scale on which you can start to amortise fixed costs (product, sales, marketing, support).<\/li>\n<\/ul>\nWhen I speak to founders they still treat ARR as a vanity metric, something to present in a pitch deck, rather than as a starting point to ask: <em>\u201cCan this ARR sustain the cost structure we are building?\u201d <\/em>I\u2019m afraid this is often a hard truth that many don\u2019t want to face.\n<h3>1.2 <strong>ARPU, churn and expansion: three levers that define your trajectory<\/strong><\/h3>\nThree concepts shape the trajectory of a SaaS business:\n<ul>\n\t<li><strong>ARPU (Average Revenue Per User\/Account)<\/strong>: how much you earn, on average, per paying customer.<\/li>\n\t<li><strong>Churn<\/strong>: the rate at which customers cancel or significantly downgrade.<\/li>\n\t<li><strong>Expansion (or Net Revenue Retention, NRR)<\/strong>: the extent to which existing customers expand their spend via upsells, cross-sells or seat growth.<\/li>\n<\/ul>\nA high ARR driven by <strong>low ARPU and high churn<\/strong> is fundamentally fragile. A smaller ARR with <strong>higher ARPU and positive net expansion<\/strong> can be far more resilient and attractive, even if the absolute revenue is lower.\n<h3>1.3 <strong>LTV and CAC: the sanity check<\/strong><\/h3>\nTwo additional concepts close the loop:\n<ul>\n\t<li><strong>CAC (Customer Acquisition Cost)<\/strong>: how much you spend to acquire a new paying customer, across all channels (ads, SDRs, content, events, etc.).<\/li>\n\t<li><strong>LTV (Customer Lifetime Value)<\/strong>: the total value a customer is expected to generate over their relationship with you, usually after costs.<\/li>\n<\/ul>\nIf <strong>LTV is not significantly higher than CAC<\/strong>, the SaaS model is simply not viable. A common rule of thumb in the industry is:\n<ul>\n\t<li><strong>LTV\/CAC \u2265 3<\/strong>: healthy<\/li>\n\t<li><strong>LTV\/CAC \u2248 2<\/strong>: borderline<\/li>\n\t<li><strong>LTV\/CAC &lt; 1.5<\/strong>: you are burning money to grow<\/li>\n<\/ul>\nWe will come back to these ratios with a concrete example.\n\n<img decoding=\"async\" class=\"saas-img\" src=\"https:\/\/the-marketinghub.com\/blog\/wp-content\/uploads\/2025\/11\/The-SaaS-market-is-booming.jpg\" alt=\"The-SaaS-market-is-booming\" \/>\n\n<span id=\"sec2\" style=\"color: #333333; font-family: Raleway, Helvetica, Arial, Lucida, sans-serif; font-size: 1.65rem; font-weight: 900;\">2. <strong>A Simple Numerical Example: A Mid-Size B2B SaaS<\/strong><\/span>\n<div class=\"saas-article\">\n\nLet us build a very simple (but realistic) model for a mid-size B2B SaaS company.\n<h3>2.1 <strong>Base assumptions<\/strong><\/h3>\nImagine a product that sells for <strong>100 \u20ac per month<\/strong> on average per account, and the company ends Year 0 with <strong>500 paying customers<\/strong>.\n\nWe assume:\n<ul>\n\t<li>ARPU: 100 \u20ac\/month<\/li>\n\t<li>Paying customers at the end of Year 0: 500<\/li>\n\t<li>Net new customers per year: +300 (Year 1), +400 (Year 2), +500 (Year 3)<\/li>\n\t<li>Churn: 3% monthly (kept implicit in the net growth for simplicity)<\/li>\n<\/ul>\nThis is deliberately simplified, but enough to reason about orders of magnitude.\n<h3>2.2 <strong>Revenue projection<\/strong><\/h3>\nFrom these assumptions, we can create a basic revenue projection:\n\n<strong>Table 1 \u2013 Revenue projection for a hypothetical SaaS<\/strong>\n<table class=\"saas-table\">\n<thead>\n<tr>\n<th><strong>Year<\/strong><\/th>\n<th><strong>Paying customers (average)<\/strong><\/th>\n<th>ARPU (\u20ac\/month)<\/th>\n<th>MRR (\u20ac\/month)<\/th>\n<th>ARR (\u20ac\/year)<\/th>\n<th><strong>YoY ARR growth<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>650<\/td>\n<td>100<\/td>\n<td>65,000<\/td>\n<td>780,000<\/td>\n<td>\u2013<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>950<\/td>\n<td>105*<\/td>\n<td>99,750<\/td>\n<td>1,197,000<\/td>\n<td>+53 %<\/td>\n<\/tr>\n<tr>\n<td>3<\/td>\n<td>1,350<\/td>\n<td>110*<\/td>\n<td>148,500<\/td>\n<td>1,782,000<\/td>\n<td>+49 %<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n*Here I assume a modest ARPU increase driven by seat expansion or plan upgrades, not just price hikes.\n\nEven with numbers that are not spectacular, this business would move from:\n<ul>\n\t<li><strong>~0.8M \u20ac ARR in Year 1<\/strong>,<\/li>\n\t<li>to <strong>~1.8M \u20ac ARR in Year 3<\/strong>.<\/li>\n<\/ul>\nFor many founders, this already \u201csounds good\u201d. The question is: <strong>does this support the cost structure and growth ambitions of the company?<\/strong>\n<h2 id=\"sec3\">3. <strong>From Top Line to Viability: Gross Margin and Cost Structure<\/strong><\/h2>\nRevenue alone does not tell us much. We need to look at costs.\n<h3>3.1 <strong>COGS and gross margin in a \u201cclassic\u201d SaaS<\/strong><\/h3>\nIn a pure software model (without heavy AI usage yet), <strong>COGS (Cost of Goods Sold)<\/strong> typically includes:\n<ul>\n\t<li>Infrastructure (cloud, storage, bandwidth)<\/li>\n\t<li>Third-party services tightly coupled to the product<\/li>\n\t<li>Support costs (sometimes included here, sometimes treated as Opex)<\/li>\n<\/ul>\nA healthy B2B SaaS often aims for a <strong>gross margin above 70\u201375%<\/strong>. Many of the best-in-class operate in the <strong>80\u201385%<\/strong> range.\n\nFor our example, let us assume:\n<ul>\n\t<li>Gross margin: 80% (COGS = 20% of revenue)<\/li>\n<\/ul>\nIn Year 2, with <strong>ARR \u2248 1.2M \u20ac<\/strong>, this would mean:\n<ul>\n\t<li>Revenue: 1,197,000 \u20ac<\/li>\n\t<li>COGS (20%): 239,400 \u20ac<\/li>\n\t<li><strong>Gross profit<\/strong>: 957,600 \u20ac<\/li>\n<\/ul>\nThat gross profit is what you have left to fund:\n<ul>\n\t<li>Product &amp; engineering<\/li>\n\t<li>Sales &amp; marketing<\/li>\n\t<li>General &amp; administrative (G&amp;A)<\/li>\n\t<li>And, ideally, some profit at the end.<\/li>\n<\/ul>\n<h3>3.2 <strong>Opex and operating leverage<\/strong><\/h3>\nSuppose this company has the following <strong>annual operating expenses<\/strong>:\n<ul>\n\t<li>Product &amp; engineering (R&amp;D): 500,000 \u20ac<\/li>\n\t<li>Sales &amp; marketing: 600,000 \u20ac<\/li>\n\t<li>G&amp;A: 300,000 \u20ac<\/li>\n<\/ul>\nTotal Opex: <strong>1.4M \u20ac<\/strong> per year.\n\nIn that scenario:\n<ul>\n\t<li><strong>Year 1<\/strong> \u2013 ARR 780k; gross profit 624k; Opex 1.4M \u2192 negative EBITDA<\/li>\n\t<li><strong>Year 2<\/strong> \u2013 ARR 1.197M; gross profit ~958k; Opex 1.4M \u2192 still negative<\/li>\n\t<li><strong>Year 3<\/strong> \u2013 ARR 1.782M; gross profit ~1.425M; Opex 1.4M \u2192 around break-even<\/li>\n<\/ul>\nThis is very typical: <strong>a SaaS business can show healthy growth in ARR and still be structurally unprofitable for several years<\/strong>. The key question is whether the unit economics justify that path.\n\n<img decoding=\"async\" class=\"saas-img\" src=\"https:\/\/the-marketinghub.com\/blog\/wp-content\/uploads\/2025\/12\/imagen-01-en.jpg\" alt=\"Models SaaS\" \/>\n\n<span id=\"sec4\" style=\"color: #333333; font-family: Raleway, Helvetica, Arial, Lucida, sans-serif; font-size: 1.65rem; font-weight: 900;\">4. <strong>CAC, LTV and CAC Payback: the Core Test of Viability<\/strong><\/span>\n\nLet us now introduce acquisition cost and customer lifetime\n<h3>4.1 <strong>Estimating CAC and LTV<\/strong><\/h3>\nAssume the company uses a mix of:\n<ul>\n\t<li>Paid media<\/li>\n\t<li>Content &amp; SEO<\/li>\n\t<li>SDRs doing outbound<\/li>\n\t<li>Events and partnerships<\/li>\n<\/ul>\nThe fully loaded <strong>CAC per new paying customer<\/strong> ends up around <strong>1,200 \u20ac<\/strong> (which is not unusual in B2B if ARPU and retention are strong).\n\nOn the revenue side:\n<ul>\n\t<li>ARPU: 100\u2013110 \u20ac\/month<\/li>\n\t<li>Gross margin: 80%<\/li>\n\t<li>Churn: 3% monthly \u2192 expected average lifetime \u2248 1 \/ 0.03 \u2248 33 months<\/li>\n<\/ul>\nA simple LTV estimate:\n<ul>\n\t<li>Gross profit per month per customer (Year 2\u20133): around 80\u201390 \u20ac<\/li>\n\t<li>Lifetime months: ~33<\/li>\n<\/ul>\nSo:\n<ul>\n\t<li><strong>LTV \u2248 80 \u20ac \u00d7 33 = 2,640 \u20ac<\/strong> (using a conservative 80 \u20ac figure)<\/li>\n<\/ul>\nThe LTV\/CAC ratio would be:\n<ul>\n\t<li><strong>LTV\/CAC \u2248 2.2<\/strong><\/li>\n<\/ul>\nThis is <strong>not terrible<\/strong>, but it is not particularly comfortable either. It leaves limited room for error (in churn, pricing or CAC).\n<h3>4.2 <strong>CAC payback: how long until you recover the acquisition cost?<\/strong><\/h3>\nAnother way of looking at it is <strong>CAC payback<\/strong>: how many months of gross profit you need to recover the cost of acquiring a customer.\n\nWith the same assumptions:\n<ul>\n\t<li>CAC = 1,200 \u20ac<\/li>\n\t<li>Monthly gross profit per customer \u2248 80 \u20ac<\/li>\n<\/ul>\nThen:\n<ul>\n\t<li><strong>CAC payback = 1,200 \/ 80 = 15 months<\/strong><\/li>\n<\/ul>\nFifteen months is on the upper edge of what many investors and operators consider acceptable for a B2B SaaS.

Capital is more expensive, and investors are more sceptical of growth that does not rest on solid unit economics. That said, <strong>SaaS as a model is far from dead<\/strong>. It has simply returned to its fundamentals.\n\nFrom my point of view, a viable SaaS in 2026 tends to show four characteristics.\n<h3>5.1 <strong>Clear economic discipline from the beginning<\/strong><\/h3>\nThe company:\n<ul>\n\t<li>Calculates its CAC honestly (including salaries and overhead).<\/li>\n\t<li>Understands churn and does not cherry-pick cohorts to make it look better.<\/li>\n\t<li>Knows what ARPU range it needs for the business to make sense, and shapes the product accordingly.<\/li>\n<\/ul>\nThe opposite, a \u201cgrow at all costs\u201d mentality, is increasingly hard to finance.\n<h3>5.2 <strong>Real value for a well-defined segment<\/strong><\/h3>\nSaaS works best when:\n<ul>\n\t<li>The product solves a <strong>clear, painful and recurring problem<\/strong>.<\/li>\n\t<li>The buyer is identifiable (CIO, CMO, Head of Sales, founder, etc.).<\/li>\n\t<li>The usage is frequent enough to justify a subscription.<\/li>\n<\/ul>\nA generic tool with weak differentiation, aimed at \u201ceveryone\u201d, usually ends up in a race to the bottom on pricing.\n<h3>5.3 <strong>A path to operating leverage<\/strong><\/h3>\nFounders and investors should be able to answer:\n<ul>\n\t<li>At what <strong>ARR level<\/strong> does the company realistically reach break-even?<\/li>\n\t<li>How does the <strong>ratio between sales &amp; marketing spend and ARR<\/strong> evolve over time?<\/li>\n\t<li>What happens if growth slows down for a year?<\/li>\n<\/ul>\nA good SaaS business shows an increasingly favourable relationship between:\n<ul>\n\t<li>Growth in ARR<\/li>\n\t<li>Growth in Opex<\/li>\n<\/ul>\nThat is what creates real value in the long term.\n<h3>5.4 <strong>A mature conversation about risk<\/strong><\/h3>\nFinally, a viable SaaS business in 2026 is one that knows how to discuss risk in a mature way:\n<ul>\n\t<li>Dependence on a few large customers<\/li>\n\t<li>Exposure to platform changes (APIs, app stores, marketplaces)<\/li>\n\t<li>Regulatory and privacy risks (especially in highly regulated sectors)<\/li>\n\t<li>Competitive pressure from incumbents and from AI-driven new entrants<\/li>\n<\/ul>\nIgnoring these elements does not make them go away; it simply moves the problem to the next funding round.\n<h2 id=\"sec6\">6. <strong>A Brief Note on AI Before We Dive Deeper in the Next Article<\/strong><\/h2>\nIn this first article I have deliberately focused on <strong>\u201cclassic\u201d SaaS models<\/strong>, without getting into AI and LLMs beyond a passing reference. There is a reason for that: <strong>if the underlying SaaS economics do not work, adding AI will not fix them<\/strong>. It will very likely make them more complex and more expensive.\n\nIn the next article, I will look specifically at:\n<ul>\n\t<li>How AI-based SaaS products introduce <strong>new cost structures<\/strong> (tokens, inference, context windows).<\/li>\n\t<li>How these costs interact with ARR, ARPU and CAC.<\/li>\n\t<li>And why many apparently successful AI products have unit economics that are more fragile than they look at first sight.<\/li>\n<\/ul>\nFor now, the key message is simple:\n\n<strong>SaaS is still a viable model in 2026, but only for teams that treat it as a real business, not as a label.<\/strong>\n\n<\/div>\n<!-- ===========================        REFERENCIAS \u2014 CAJA COMPLETA   ============================ -->\n<div class=\"ref-box\">\n<h2 id=\"sec_referencias\">References &amp; Further Reading<\/h2>\n<ul class=\"ref-list\">\n\t<li>Bessemer Venture Partners (BVP).
