B2B SaaS Market Dynamics in 2024: Growth, Consolidation, and the AI Inflection
The B2B SaaS market in 2024 does not resemble the B2B SaaS market of 2021. The differences are not merely cyclical — they are structural. The financing environment has changed, the buyer behaviour has changed, and the competitive dynamics at nearly every layer of the stack have changed. What has not changed is the scale of the opportunity: enterprise software remains one of the largest and most durable categories in technology, and the companies being built today in the most defensible parts of this market will be among the most consequential technology businesses of the next decade.
This piece is our attempt to characterise where the B2B SaaS market actually stands in 2024, drawing on publicly available data, the operating metrics of the companies we follow most closely, and our own experience as investors in the category. We focus primarily on the segments most relevant to our investment thesis — the infrastructure layer, developer tools, enterprise workflow automation, and applied AI — and on what the dynamics in these segments mean for founders building today.
The Correction and What Came After
The 2021 peak of B2B SaaS valuations was, in retrospect, a period of extraordinary multiple expansion driven by a combination of low interest rates, accelerated enterprise digital adoption during the pandemic, and investor enthusiasm that outpaced underlying fundamental performance. The correction that followed between 2022 and 2023 was severe. Public SaaS multiples compressed from a median of 15–20x forward revenue to 5–8x. Private market valuations followed with a lag, and many companies that had raised at 2021 valuations found themselves facing down rounds, flat rounds, or the prospect of raising significantly less capital than they had anticipated.
What is important to understand about the 2024 environment is that the correction is now largely complete. The companies that survived it — and many did not — are operating in a market that has reset to a healthier baseline. The median Series A in B2B SaaS in 2024 was raised at approximately 8–12x ARR, compared to 25–40x in 2021. This is not a depressed market; it is a rational one. The companies raising at these multiples are doing so on the basis of real revenue, real growth, and increasingly real proof of enterprise retention. The speculative excess has been wrung out, and what remains is a market where capital allocation is more likely to track fundamental performance.
For seed-stage founders, the implication is important: the path from seed to Series A is longer and more evidence-intensive than it was in 2021. Investors at the Series A are expecting to see meaningful ARR — typically $1–2M minimum, and ideally $2–3M with good net revenue retention — before committing. This means that seed capital needs to be deployed against a clear plan for reaching those metrics, and that the eighteen-month sprint to product-market fit that characterised the 2021 environment has been replaced by a more deliberate two- to three-year construction process.
Ramp and the Fintech-SaaS Convergence
Among the most instructive growth stories in B2B SaaS in recent years is Ramp, the corporate card and spend management platform that raised a $750M funding round in 2024 at a valuation of approximately $7.65 billion. Ramp's trajectory is interesting for several reasons that go beyond the headline numbers.
First, Ramp demonstrates the power of building a product that is genuinely better by measurable criteria rather than merely different. The company was founded in 2019 with an explicit thesis that corporate cards and expense management were categories defined by incumbents whose incentives were misaligned with their customers' interests. Ramp's product was designed from the ground up to save companies money — by flagging duplicate subscriptions, identifying cost reduction opportunities, and automating compliance tasks that were previously manual. The value proposition was specific and falsifiable: Ramp would save its customers, on average, 3.3% of their total spend annually. That claim was backed by data, communicated with specificity, and used as the primary proof point in sales conversations.
The result was one of the fastest revenue growth trajectories in B2B SaaS history. Ramp grew from $0 to $300M in annualised revenue in approximately four years — a pace that placed it among the fastest-growing enterprise software companies ever documented. More importantly, it maintained this growth while achieving unit economics that were positive at the customer level from very early in its history, a rarity in a category where high customer acquisition costs and long sales cycles typically produce negative payback periods well into a company's growth phase.
The second reason Ramp is instructive is that it represents the convergence of fintech and SaaS that has become one of the most important structural trends in enterprise software. The most valuable enterprise software companies of the next decade will not merely charge subscription fees; they will embed financial services — payments, credit, insurance, lending — directly into their workflows. Ramp does this with corporate credit. Rippling is doing it with employer-of-record and payroll. The pattern will repeat across every major category of enterprise workflow where financial transactions are embedded in the underlying process.
Retool and the Low-Code Plateau
Retool's $45M Series C, raised in 2021 at a valuation that established it as one of the most valuable developer tools companies of its generation, was followed by a period of more measured growth that reflects the dynamics of the low-code and internal tooling category more broadly. Retool had identified a genuinely important problem — the disproportionate engineering time spent building internal dashboards, admin panels, and operational tools rather than customer-facing product — and had built a product that addressed it with enough sophistication to earn adoption in some of the most demanding engineering organisations in the world.
The challenge Retool faced in 2023 and 2024 was not product quality; it was category definition. The low-code market suffered from a proliferation of vendors — Appsmith, Budibase, Tooljet, and dozens of others — that competed on price (most were open source) rather than functionality, and from a broader enterprise buyer fatigue with tools that promised to democratise development but in practice required significant ongoing engineering involvement. The result was a market that grew more slowly than its 2021 advocates had predicted, and where the most successful companies were those that had earned deep adoption in specific workflows rather than positioning themselves as general-purpose development environments.
The broader lesson from Retool's trajectory is one that we believe applies across the low-code and developer tooling market: horizontal platforms that attempt to abstract over the entire application development lifecycle face the structural problem that their value proposition — "build anything without code" — is too broad to be defensible against vertical competitors who build better tools for specific workflows. The companies that are winning in this market in 2024 are those that have chosen specific verticals and built tool chains that are genuinely better for those verticals than anything else available.
"The most valuable enterprise software categories of the next decade will be defined not by what they replace but by what they make possible. The question is not whether AI will change B2B SaaS — it already has. The question is which changes are structural and which are cosmetic."
Glean and the Enterprise AI Search Race
Glean raised a $200M Series D in 2024 at a valuation of $2.2 billion, making it one of the most valuable pure-play enterprise AI companies in its cohort. Glean's product — a workplace search and knowledge discovery tool that uses large language models to surface relevant information across an organisation's full software stack — addresses a problem that every enterprise knowledge worker experiences daily: the difficulty of finding information that exists somewhere in the organisation's collective memory but is distributed across dozens of applications.
The Glean story is instructive as a case study in what enterprise AI adoption actually looks like in practice, as distinct from what technology journalists and conference presentations suggest it looks like. Glean's adoption is not primarily driven by AI sophistication. It is driven by three much more mundane factors: the quality of its connectors to enterprise software systems (Slack, Confluence, Google Workspace, Salesforce, and dozens of others), the reliability of its permission management (which ensures that employees only see information they are authorised to access), and the quality of its onboarding and change management support.
This observation — that enterprise AI adoption is primarily an integration and change management problem rather than a model capability problem — is one of the most important structural insights about the 2024 enterprise AI market. The companies winning in this market are not necessarily those with the most advanced models; they are those with the best integration layer, the most reliable permission and security architecture, and the most effective processes for managing the organisational change that AI deployment requires. This is a category where the technical moat is smaller than it appears and the go-to-market and integration moat is larger.
Moveworks and the Automation Premium
Moveworks raised $200M at a valuation that positioned it as one of the most well-capitalised enterprise AI companies focused on internal IT and HR automation. The Moveworks story illustrates a dynamic that is increasingly important in the enterprise AI market: the premium that buyers are placing on automation that removes headcount rather than merely augmenting existing workflows.
The enterprise buyer in 2024 has become significantly more sophisticated about AI value propositions. The generic "AI will make your employees more productive" claim that drove significant software purchases in 2022 and 2023 has given way to a more demanding buyer who wants to see specific, measurable reductions in either headcount cost or process cycle time before committing to an enterprise contract. Moveworks has been successful in this environment because its value proposition is expressed in terms that CFOs understand — reduced IT support tickets, lower average handling time, measurable reduction in tier-one support labour costs — rather than in terms of abstract productivity improvement.
The implication for founders building enterprise AI products today is direct: buyers are not buying AI; they are buying outcomes. The founders who will win in this market are those who can translate their product's capabilities into specific, measurable business outcomes that justify a specific line item in an enterprise budget. This is harder than building impressive product demos, and it requires a different kind of go-to-market expertise than the product-led growth motions that drove adoption in the 2019–2021 developer tools era. But it is also more defensible, because outcomes-based selling creates stickier customer relationships and higher switching costs than usage-based pricing alone.
Writer and the Vertical AI Premium
Writer's $100M Series C, raised in 2024, validated the thesis that vertical AI products built for specific enterprise workflows can command significant premiums over generic AI writing tools. Writer is not competing with ChatGPT or Claude as a general-purpose AI assistant; it is competing as the AI layer for brand and content workflows in large enterprises, with specific features for brand voice compliance, content approval workflows, and integration with enterprise content management systems.
The Writer story illustrates a pattern that we expect to repeat across many enterprise software categories in the next several years: the commoditisation of foundation model capabilities will drive buyers to evaluate AI products less on the sophistication of the underlying model and more on the quality of the workflow integration, the reliability of the compliance and governance features, and the depth of the enterprise content stack integrations. In this environment, the companies that have built deep vertical expertise — in legal, in compliance, in brand management, in financial services — will command significant premiums over generic tools that position themselves as appropriate for all use cases.
The Developer Tools Renaissance
One of the most striking features of the 2024 B2B SaaS market is the sustained strength of developer tools despite the broader market correction. Vercel, the deployment and hosting platform for frontend developers, raised $150M in 2023 at a valuation of $3.25 billion. Linear, the engineering project management tool that has become the default choice for product and engineering teams at a significant proportion of well-run technology companies, raised a $35M Series B. Clerk, the authentication infrastructure product, raised $15M in a Series A that demonstrated robust demand for best-in-class authentication tooling at the startup and scale-up tier.
These outcomes reflect a structural feature of the developer tools market that has remained consistent across market cycles: developers make buying decisions differently from other enterprise buyers. They evaluate products through direct use, they share their findings within professional communities with high transparency, and they are willing to pay meaningful amounts for products that make them measurably more productive at the specific tasks they perform most frequently. This combination — direct evaluation, community-driven word of mouth, and willingness to pay for quality — produces go-to-market dynamics that are more efficient than enterprise sales-led motions and more defensible than pure consumer viral growth.
The developer tools companies that have performed best in the 2024 environment share a common characteristic: they have built products that are genuinely better by the criteria that developers use to evaluate tools — API quality, documentation quality, integration breadth, performance — rather than products that win on price or marketing. Vercel's success is built on the quality of its deployment experience and its integration with Next.js, the React framework that has become the dominant approach for building modern web applications. Linear's success is built on the quality of its interface and its adherence to a design philosophy that treats issue tracking as something that should be fast and pleasant to use, not merely functional. These are craft-driven companies in the most literal sense: they are winning because they built things that are better than the alternatives.
Seed-Stage Signals in a Changed Market
What does all of this mean for seed-stage B2B SaaS companies in 2024? Several things, in our view.
First, the AI infrastructure opportunity is real but crowded. The number of companies positioning themselves as the AI layer for enterprise workflows has increased by an order of magnitude in the past two years. The companies that will succeed in this category are those that have a specific, defensible insight into a particular workflow or vertical that generic AI infrastructure providers cannot replicate. Founders who are building in enterprise AI without a specific vertical or workflow conviction are building in a market where differentiation is increasingly difficult.
Second, developer tools remain one of the best seed-stage markets in B2B SaaS because the go-to-market efficiency of the developer community continues to provide outsized returns on product investment. Companies like Inngest, which raised a $6.5M seed round to build background job infrastructure for modern web applications, or Depot, which raised $6M to build a faster Docker build service, are addressing specific, well-defined problems for a buyer who evaluates products with high sophistication and converts with high efficiency. These are not glamorous markets. But they are markets where the best product wins, and where seed capital is sufficient to reach meaningful traction.
Third, the enterprise SaaS buying environment in 2024 rewards specificity over breadth. The horizontal platform play — the company that wants to be the OS for its category — is more difficult to execute in the current environment because buyers are more cautious about vendor consolidation risk and more demanding about proof of value in specific workflows before committing to broader platform adoption. The companies that are winning new enterprise contracts are those that enter through a specific workflow with a specific value proposition and expand from that beachhead with demonstrated ROI.
Fourth, net revenue retention remains the single most important metric in B2B SaaS for distinguishing great businesses from merely good ones. The companies in our portfolio with the highest NRR — consistently above 120% — are the ones that are growing through expansion within existing accounts in addition to new customer acquisition. This is the characteristic that separates true platform businesses from point solutions, and it is what we look for most carefully in evaluating the commercial health of a seed-stage company at the point of Series A preparation.
The 2024 B2B SaaS market is not the exuberant market of 2021. It is a more disciplined, more evidence-intensive, and arguably more interesting market — one where the best companies are winning on merit rather than on narrative, and where the fundamentals of building great software for specific enterprise buyers have reasserted themselves as the primary determinants of value. For seed-stage founders with a clear thesis, a specific workflow insight, and the patience to build methodically toward product-market fit, the opportunity is as large as it has ever been.
