Sonu Goswami Why Product/Market Fit Doesn’t Guarantee B2B Success
Achieving Product/Market Fit is just the beginning. Learn why it's not enough and discover the critical steps B2B startups must take to scale successfully.
The Myth of “PMF Solves Everything
A lot of founders believe that once they hit Product/Market Fit, everything else will fall into place. Just pour money into marketing, hire some salespeople, and watch revenue climb.
I wish it worked that way. It doesn’t.
For most B2B startups, this is exactly where things start breaking. You scale too fast, sales don’t close, churn creeps in, and cash burns way quicker than expected.
The Real Challenge After PMF
Product/Market Fit only proves one thing: your product solves a real problem. That’s huge, but it doesn’t mean you’ve figured out how to sell it repeatedly and at scale.
That next part—the sales motion—is just as hard as finding PMF in the first place. And it’s where a lot of teams crash.
The Temptation to Skip Steps
The temptation is to skip steps. But if you hit the gas before you have a repeatable process, you’re basically pouring fuel on a damp log. A lot of smoke, no fire.
Here’s what actually matters:
- You can’t skip stages. Jumping ahead wastes time and money.
- After PMF, your focus shifts from proving the product to proving the growth engine.
- Early sales hires shouldn’t define your playbook—they should run it. Bring them in too early, and they’ll stall you.
- Founders need to lead the early sales motion. Bring in a “pathfinder” rep only once you’ve started seeing a pattern.
- Cash burn should stay low until you’re certain the process works. Then (and only then) is it time to scale.
Remember: your valuation climbs as you de-risk each stage—not just when you raise your burn rate.
Where Founders Slip Up
I’ve seen the same mistakes play out again and again:
- Building too much before talking to real buyers.
- Hiring sales teams before proving the product actually sells.
- Scaling prematurely—chasing “growth” without repeatability.
- Ignoring churn while pushing new acquisition.
- Forgetting unit economics (LTV:CAC, payback period).
Each one of these errors bleeds cash and time.
A Founder’s Roadmap to Predictable Growth
Think of this less as a checklist and more as a natural progression:
- Talk to real buyers. Validate your assumptions.
- Refine your product based on what they tell you.
- Take the first sales calls yourself—this is how you hear the objections firsthand.
- Start noticing patterns in what works and what doesn’t.
- Once you’ve cracked some messaging that lands, bring in 1–2 reps. See if they can repeat it. Watch carefully.
- Track the numbers—revenue consistency, churn, profitability. That’s how you know you’re not just lucky.
- When it stops being a fluke and starts looking like a machine, then scale. Hire, spend, push growth.
The Bottom Line
Product/Market Fit is the starting line, not the finish.
Until you’ve proven a repeatable sales process, your job as a founder is simple: keep cash burn low, stay close to customers, and resist the urge to hit the gas.
Once you’ve nailed it, scaling won’t just feel easier—it will actually be sustainable.
