In an era where artificial intelligence is redefining every aspect of sales and marketing, Go-To-Market (GTM) has become a key survival tool for B2B startups. Data from the report ICONIQ Analytics: The State of GTM in 2025 show that while overall ARR (annual recurring revenue) growth remained stable year-on-year, companies with revenues between $25 million and $100 million saw growth of a whopping 93% compared to 78% in 2023.
For young startups, this means one thing: market entry is no longer about rapid product launches, but about continuous testing and adapting to changing dynamics. The iterative GTM model, based on MVP (minimum viable product) and customer feedback, remains the best starting point.
Slack, which grew based on a freemium model and user snowball effect, remains an example of how to scale through genuine value and organic adoption. The key was understanding that the product's first advocates weren't IT departments, but rather operational teams, who naturally shared the tool within the organization.
The modern GTM landscape requires founders to think systems-wise. It's no longer enough to just have a good product.You need to understand how a customer makes a purchasing decision, who influences that process, and what barriers stand in the way of closing a deal. It's this knowledge, gained through iterative testing, that distinguishes startups that scale quickly from those that plateau.
The foundation of an effective B2B GTM strategy is a clear definition of the ideal customer profile (ICP), tailoring communication to the segment, and consistently iterating the offer (ICONIQ). 57% of B2B companies declare that precise segmentation and personalization of the message are the greatest success factor in lead conversion.
In practice, this means that startups that can describe "why their customer buys," not just "who buys," have a much greater chance of gaining market traction. For sales teams, it also means a change in mindset: GTM is not a sales department, but a system that encompasses marketing, product, and customer success.
The indicators that best signal the health of GTM in 2025 are:
This shows that the foundation of GTM is not magic, but consistent data analysis and operational discipline.
It's also crucial to understand that each market segment requires a different approach. A startup selling a tool to small businesses (SMEs) will operate completely differently than one targeting enterprises. In the former, a simple onboarding path and a self-service model are key, while in the latter, decision-making processes lasting several months, proof of concept, and dedicated implementation support are key.
Many founders make the mistake of trying to serve both segments at the same time, which results in message confusion, inefficient use of resources, and team frustration. Therefore, the most important decision in the early-stage phase is the choice of one segment and deep entry into it.
The most successful startups in 2025 combine data, strategy, and people into a single system. At the tactical level, this includes:
Precisely identifying which companies constitute a real target market. Well-defined ICP is not only about the industry and the size of the company, but also understanding the problems, budgets, purchasing processes and alternative solutions that the customer uses today.
A message based on results, not product features. The customer isn't buying a "report automation tool," but "3 hours of time saved per week for every manager." It's the difference between talking about yourself and talking about the customer.
Matching channels to the growth stage. Outbound and direct sales often work best initially, followed by content marketing and SEO, and in the expansion phase, partnerships and indirect channels.
Tools and processes supporting the GTM team: CRM (such as HubSpot or Salesforce), sales engagement platforms (Lemlist, Apollo), analytical tools and increasingly AI assistants supporting research, personalization and follow-up.
Report ICONIQ indicates that the importance of hybrid models combining direct sales, partner channels and the so-called "land & expand" by end users is growing. Interestingly, as much as 20% of revenues of medium-sized SaaS companies in 2025 come from partner channels. This is a signal that the success of GTM requires diversification of ways to reach the customer.
This is also worth noting that companies who build a lead in one channel early on and then gradually add others perform better than those that try to operate everywhere at once. This is a classic case of "focus before scale," a principle that's easy to understand but difficult to consistently implement.
Many startups start their GTM journey with outbound.That is reaching potential customers directly. The reason? Full control over the message, rapid hypothesis validation, and immediate feedback.
SaaS companies are using outbound not only for sales but primarily as a research tool. Metrics such as open rate, reply rate, and demo-to-deal conversion are becoming real market test metrics. However, from a 2025 perspective, outbound is undergoing a transformation: 70% of GTM teams now use AI in prospecting and communication personalization processes.

As a result, outbound becomes the startup's first laboratory. A place where benefits language, targeting, and value proposition are tested. It's no coincidence that AI-native companies achieve a 24 percentage point higher conversion rate from a free trial to a paid plan than traditional SaaS (56% vs. 32%).
A well-designed outbound campaign allows you to find answers to key questions within a few weeks: Does our message resonate? Are we speaking to the right people? Is the timing right? Does the offer address a real pain point?
For example, a startup offering a compliance tool might discover that its best ICP isn't large corporations (where processes are too complex), but rather pre-IPO companies that need to quickly get their processes in order before an audit. This knowledge changes everything from targeting, to messaging, to roadmap products.

From a startup's perspective, GTM is not just about sales, it's about a validation process Product-Market Fit Every outbound campaign, every customer conversation, and every unsuccessful pitch is data. This data shows which messages work, which product features evoke emotions, and where the barriers to purchase lie.
In this sense, PMF is a learning tool. A product that has gone through hundreds of message iterations has a much greater chance of scalability than one that was immediately "perfect on paper."
The so-called "momentum of learning" plays a key role here, i.e., the speed at which a startup collects and processes market feedback. Companies that can analyze campaign results, modify the message, and launch the next iteration within a week learn four times faster than those that make decisions quarterly.
It's also worth remembering that PMF is not a binary state (there is/there isn't), but a continuum. You can have an "early PMF" in a narrow segment and gradually expand it. Often, this strategy of deep niche penetration before entering a broader market yields the best long-term results.

In 2025, effective GTM is not a plan, this is a process. The best teams connect an agile mindset with hard data and AI that supports analysis and personalization of activities. This shows that GTM is no longer a "marketing project," but an infrastructure for company growth.
It begins with a precise ICP, progresses through communication (outbound) testing, and culminates in achieving PMF and setting the stage for scaling. Each of these stages requires different competencies, tools, and metrics, but they all share one common thread: customer focus and a willingness to learn.
In short:
It's in this process that competitive advantage is born, not in the product, not in the team, but in the ability to adapt and engage with the market in real time. Startups that understand this don't just build products; they build a learning machine that operates faster and more effectively with each passing quarter.
The key is to remember that GTM doesn't end with your first sales successes. It's a living organism that requires constant optimization, experimentation, and most importantly - listening to the market Because ultimately, it's the customer, not the founder's vision, that determines whether a startup survives.
