Main Theme – Learning Product-Market Fit from Serial Entrepreneur Exits

In this episode, Scott D. Clary sits down with Shirish Nadkarni, an entrepreneur with three exits and author of "From Startup to Exit." Together, they explore the challenges founders face in finding true product-market fit, why timing and customer understanding matter more than raw innovation, and what practical steps early-stage startups can take to reduce risk. Nadkarni draws on his experiences to share strategic insights on knowing when to pivot, validating ideas before building, and deciding when to raise, pivot, or exit.

Key Discussion Points & Insights

1. Raising Capital Pre-Revenue & Market Realities ([02:22])

• Dot-Com Boom Context:
  Nadkarni recounts raising $15 million on a $23 million pre-money valuation at the height of the dot-com boom, based solely on his reputation and having only a beta product.

  • “It was totally crazy times at that time to be able to raise that kind of money without really having any kind of revenue or customer traction.”—Shirish Nadkarni [02:42]

• Iteration and Market Response:
  Despite quickly signing up users, early retention was poor. Nadkarni attributes this to market discomfort:

  • “People were still uncomfortable using email in the cloud and relying on some other company to store very sensitive corporate information...So it became clear to us that the original idea was not working.”
  • This led to a pivotal decision to shift from a broad cloud email solution to providing mobile access to existing email accounts, anticipating smartphone demand.

2. The Critical Importance of Timing ([05:12])

• Lessons Learned in Hindsight:
  Nadkarni admits he would have invested more in market research upfront, acknowledging the timing was off for SaaS cloud-based email in the late 1990s.
  • “The idea was great, but the timing was not right because it took quite some time for companies to become comfortable with using software on the cloud.”
  • He stresses: truly innovative products often require a market that is ready, not just a working solution.

3. Practical Tactics to Find Product-Market Fit ([09:19])

• Customer Interviews First:
  Avoid presenting your solution immediately—focus on discovering customers’ top problems:

  • “Understand what are the top three or four problems that they have in the domain...If your problem that you're addressing is not in the top three or four, then...you may want to pivot.”—Shirish Nadkarni [09:33]

• Demand Testing Before Building:
  Test real demand using a landing page and digital ads before investing in development:

  • “Actually creating a website and using Google SEM or Facebook ads, drive users to that website and see if you can get customers to register for your solution, because that will tell you...what kind of an uptick are you going to get?”
    Calculate lifetime value versus acquisition cost to ensure a viable business.

4. Pivoting and Strategic Growth ([11:51])

• Pivot Story:
  After pivoting to mobile email, Nadkarni’s company (TMON) gained traction with T-Mobile and caught BlackBerry’s attention by offering broader email access than their own devices.

• Acquisition by BlackBerry:
  BlackBerry, seeking to expand beyond Microsoft compatibility, considered licensing TMON’s software but opted instead for full acquisition in 2002, especially given their global carrier relationships and the challenging fundraising climate after the dot-com crash.

  • “Given that BlackBerry was becoming quite well known and...had existing relationships with wireless carriers around the world, we could get much wider distribution...as opposed to trying to do it on our own.”
    The technology became BlackBerry Internet Email and scaled to 50 million users—a testament to the power of strategic acquisition at the right time.

5. Navigating the Exit Decision ([13:40])

• Choosing to Sell vs. Raising More:
  The episode delves into how founders must weigh funding conditions, market timing, and distribution potential when deciding on an exit.
  • “We did have actually an offer from our existing investors to continue to fund the company, but the terms were not very attractive for us… valuations had come down significantly...BlackBerry had relationships with all the major carriers around the world...So we would have been much more successful getting distribution for our software through BlackBerry than trying to do it on our own.”
    Nadkarni’s decision was anchored in broadening reach and adapting to macroeconomic reality (dot-com bust).

Notable Quotes & Memorable Moments

• On the pressure of raising funds pre-revenue:
  “You have a lot of responsibility to your investors. Yeah, I think I would have done it differently. I would have done a lot more market research initially to validate whether the idea made sense at that time.”—Shirish Nadkarni [05:12]

• On customer discovery:
  “If your solution is not addressing a top three or four problem, then even though they may be addressing a need, it may not be top of mind to customer...your sales cycles will be extremely long.”—Shirish Nadkarni [09:33]

• On testing before building:
  “Drive users to that website and see if you can get customers to register...that will tell you when you actually start marketing your solution, what kind of an uptick are you going to get?”—Shirish Nadkarni [10:23]

• On exit decisions in uncertain markets:
  “Valuations had come down significantly at that point because of the.com bust...BlackBerry had relationships with all the major carriers around the world. And so we would have been much more successful getting distribution for our software through BlackBerry than trying to do it on our own.”—Shirish Nadkarni [14:19]

Summary Flow

The conversation offers a candid look at how even “crazy times” and reputation-fueled fundraising cannot substitute for genuine market readiness and understanding user priorities. Nadkarni’s experience proves the value of pivoting early, validating ideas through direct user engagement and low-cost testing, and the importance of seizing the right distribution opportunities—even if that means selling to a larger acquirer when market conditions shift.

For founders, the takeaway is clear: discover real customer pain, test before you build, stay humble about timing, and be strategic about exits—knowing sometimes, partnerships or acquisitions are the true accelerators of your product’s impact.

Discover why timing and customer insight often matter more than innovation. Understand how testing demand before building saves time and capital, and uncover the strategic thinking behind knowing when to pivot, raise or exit. Some of the Obviously some of the lessons that you learned in that first company you founded are things that you speak about in the book. But one of the things that are obviously like a big issue for startups is the fact that nine out of ten of them fail, mostly because they don't think find proper product market fit. So how did you, how did you find that proper product market fit? What was your strategy for that? And also just a follow up question, I want you to give some context. Did you raise that money pre revenue or did you wait until you were actually you found product market fit you were selling to the market before you raised that 15?

[B]

Yeah, that's a great question. No, this was during the crazy days of the dot com boom and based on my reputation, having worked for Microsoft obviously was a big help. We had Only developed beta software when I started raising money and I raised $15 million in funding on a pre revenue basis. So we didn't have any revenue at that point and I raised it on a pre money valuation of 23 million. So it was totally crazy times at that time to be able to raise that kind of money without really having any kind of revenue or customer traction. But to answer your first question about product market fit, what we discovered, it took us about six months to kind of iterate through various versions of our software. We were able to sign up a lot of users, but we didn't really get good retention. And I think that was because people were still uncomfortable using email in the cloud and relying on some other company to store very sensitive corporate information, which is your email information. And so it became clear to us that the original idea was not working. And so we decided to pivot our solution to providing mobile access to your existing email. This was the time when BlackBerry was getting started. They had about a couple of hundred thousand users and it was a small pager form factor, BlackBerry instead of the smartphone form factor. At that time, regular phones were becoming Internet enabled and you had something called a WAP browser on your phone and which on a very small screen allowed you to access the Internet. And so we decided that, hey, why do you need a specialized device like BlackBerry which can be expensive, why not enable access to your email on your phone? And that's what we did. We basically reverse engineered all the proprietary email systems like Microsoft Exchange and Lotus Notes and AOL mail and Hotmail and so forth. And we would allow you to access that email from your phone wherever you are.

[A]

Understood?

[B]

Okay.

[A]

And so your, your products. So that's a, that's a pretty crazy startup story. So you, the fact that you raised 15 million free revenue, so you, you were, you were playing with investors money while still trying to figure out product market fit and you were iterating. I'm just curious, would you have done it differently if you could redo it? Was that a lot of stress with the 15 million free revenue?

[B]

It sure was a lot of stress. You have a lot of responsibility to your investors. Yeah, I think I would have done it differently. I would have done a lot more market research initially to validate whether the idea made sense at that time. Today the idea of TMON is something that is widespread. So it was a matter of timing. The idea was great, but the timing was not right because it took quite some time for companies to become comfortable with using software on the cloud. We were one of the first SaaS software introduced into the market. At that point, whenever you introduce a new concept, it takes time for companies to adopt it. I wish I'd done a lot more market research to really understand, hey, you know, is this something that is ready, you know, in terms of market acceptance or not?

And what, what advice would you have for somebody who, after you've learned and you've gone through this to find that product market fit or to validate that idea before you take it to market?

[B]

Yeah, I talk about that in my book From Startup to Exit. I have a whole chapter dedicated to achieving product market fit. And so what I.

[A]

It's not an easy. It's not a quick, easy thing.

[B]

Yeah. What I recommend is obviously conduct a lot of customer interviews and don't even talk about your solution first or ask the customer if they like your solution first. Understand what are the top three or four problems that they have in the domain that you are kind of researching. And if your problem that you're addressing is not in the top three or four, then right there you may want to pivot and understand. Okay, tell me more about your top three or two or three problems and maybe there is a solution I can build that is more of interest to you. Because if your solution is not addressing a top three or four problem, then even though they may be addressing a need, it may not be top of mind to customer. And as a result, your sales cycles will be extremely long because the customer is going to say, I'm going to first address my critical problems and then I'll get to some other problems that I need to address first. Focus on the top three or four problems. Make sure that your solution tackles that. The other thing that I recommend is actually testing, even before you built your software, is actually creating a website and using Google SEM or Facebook ads, drive users to that website and see if you can get customers to register for your solution, because that will tell you when you actually start marketing your solution. What kind of an uptick are you going to get? And are you going to get enough users? And is it going to cost you how much it's going to cost you to really acquire those users? And can you build a profitable business where your lifetime value for your customer is far greater than the cost of customer acquisition? So those are two things I'd highly recommend that people follow in terms of methodology for achieving product market fit.

[A]

It's very smart. And as tmon grew, walk me through the growth of the company and eventually your decision to sell it, I guess is the best way to put it. So keep walking me down your story.

[B]

Yeah. So once we decided to pivot to providing mobile email software, then we started marketing to wireless carriers because they had to install our software and make it available to their customers. And we got traction with T Mobile, which is based out of here in Seattle. They were very interested in the solution that we were providing. And then we also started talking to BlackBerry because BlackBerry at that time was limited in its access to only Microsoft email software, whereas we provided access to a whole range of proprietary email systems. And so as we started discussions on licensing our software to them, they came to the conclusion that this was very strategic for them and they would be better off acquiring our company. And so in 2002, they made an offer to acquire TMON. And we decided to at that point, that given that BlackBerry was becoming quite well known and because they had existing relationships with wireless carriers around the world, that we could get much wider distribution for our software through BlackBerry as opposed to trying to do it on our own. And this was also a time when the dot com bust had happened, and so raising money was very, very hard at that point. So the sale to BlackBerry made a lot of sense for the company and we did extremely well. Our technology became known as BlackBerry Internet Email, and it grew to about 50 million BlackBerry users over time, and so had really widespread usage within the BlackBerry community.

[A]

What are. And when you were going through that process, so they were thinking about licensing it. And then the conversation started around whether or not we should just acquire this software. What were some of the things that you were thinking? Because when you build a company, there's different ways to exit, right? You can go for another funding round. You could technically IPO it, or you could just sell it to a company. So why did you. I think you sort of alluded to it because the.com bust, it was harder to potentially take it in other directions. Is that the reason why you decided to sell to BlackBerry, or what other considerations should you think about when you're trying to exit a company?

[B]

Yeah, that's a great question, because a lot of founders have to come to that decision point at some point, whether they are actively selling their company or whether somebody approaches them for an acquisition. In our case, as I said, funding was very difficult to raise. We did have actually an offer from our existing investors to continue to fund the money fund the company, but the terms were not very attractive for us because valuations had come down significantly at that point because of the.com bust. And the second consideration was the fact that BlackBerry had relationships with all the major carriers around the world. And so we would have been much more successful getting distribution for our software through BlackBerry than trying to do it on our own. And that ultimately worked out for us because as I said, our technology reached about 50 million BlackBerry users within a few years. And it was also critical for BlackBerry because they were able to not only reach large enterprises, but also small businesses. You know who could use BlackBerry because of our software.
