LIINA LAAS Founder-led sales: A practical guide to discovery calls that win customers

There’s a moment every founder reaches sooner or later. You’ve built the product. You’ve told everyone who’ll listen about it. Your LinkedIn posts are getting likes from people who would never buy your product, your cold outreach is finally generating meetings, and someone has agreed to give you thirty minutes of their time.

Now what?

Most founders assume this is where selling begins. It isn’t. This is where learning begins.

One of the biggest misconceptions in startups is that founder-led sales is about becoming a great salesperson. Spend enough time on LinkedIn and you’ll be convinced your success depends on mastering the latest sales methodology, perfecting your objection handling or learning how to 'close'. Those skills matter eventually, but not at the beginning.

At the beginning, founder-led sales has a completely different purpose.

You’re trying to answer one question: are we building something people genuinely need?

Every customer conversation is an opportunity to test an assumption. Are you talking to the right customer? Have you identified a painful enough problem? Does your messaging resonate? Are people describing the problem in the same way you describe it, or are you solving something they don’t actually care about?

The founders who build successful companies aren’t necessarily the ones who pitch the best. They’re the ones who learn the fastest.

Sales starts long before the first demo

One mistake I see repeatedly is founders believing sales begins when someone books a meeting. It doesn’t. Sales begins when you define who you’re trying to help.

If I asked ten early-stage founders who their ideal customer is, most would answer with something like 'SMBs' or 'B2B companies'. Those aren’t customer profiles. They’re continents.

Your ideal customer profile should be painfully specific. What industry are they in? How large is the company? Who experiences the problem every day? Who signs the contract? What happens inside the business when the problem isn’t solved?

The clearer you become about your customer, the easier every other part of sales becomes. Your outreach becomes more relevant because you’re speaking to people with a shared problem. Your messaging improves because you’re using language that reflects their world instead of yours. Even your product roadmap becomes easier to prioritise because customers begin telling you which problems are worth solving first.

One of the exercises I often ask founders to complete is surprisingly simple. Before writing another cold email or booking another demo, write down the answers to five questions.

Who should we sell to?

What problem do we solve?

Why do customers buy?

How should we run our sales conversations?

What should happen after every call?

It sounds obvious, yet very few early-stage companies have documented answers to these questions. Most founders already have a sales playbook. It simply exists in their heads rather than somewhere the rest of the company can use it.  

Writing those answers down does something interesting. It forces clarity. And clarity is usually the difference between a founder who thinks they have product-market fit and one who actually does.

Stop obsessing over outreach

Founders love talking about outreach.

Should the subject line include the prospect’s first name? Should the email mention a recent funding round? Is it better to send five personalised messages or fifty generic ones? These aren’t unimportant questions, but they receive far more attention than they deserve.

Outreach has one job.

It gets someone to agree to a conversation. And this is what founders have told me repeatedly: If I can just get them to take the call, everything else is smooth sailing! Unfortunately, that is not actually the case. Now, if you don’t get them to talk to you at all, you have an even bigger problem, of course.

But moving on after you actually get them into a conversation. Discovery determines everything that happens afterwards.

I’ve watched founders spend hours rewriting a cold email that increased their reply rate by two percentage points, then spend exactly zero minutes preparing for the meeting itself. They turn up, open a slide deck, talk for half an hour about features, answer a few polite questions and finish the meeting believing it went well.

Two weeks later they’re wondering why the prospect disappeared. The problem wasn’t the outreach. The problem was the conversation.

One of the simplest ways I’ve found to explain this is with a sentence we use in our own founder sales workshop.

Outreach opens doors. Discovery closes deals. If your outreach is good, you’ll get meetings. If your discovery is good, you’ll find customers. If both are good, you’ll build a company.  

It’s remarkable how many founders reverse those priorities.

The biggest discovery mistake founders make

Most founders think discovery means asking lots of questions. It doesn’t.

Discovery means understanding the customer’s world better than they understand it themselves.

Those are very different things.

I’ve listened to founders who proudly worked through twenty discovery questions in forty minutes and still left the meeting without understanding why the customer had booked the call.

The problem is that they were interviewing the customer rather than investigating the problem.

Imagine a prospect tells you, “Our onboarding process is a nightmare.” A surprising number of founders immediately move on.

“Interesting. How many people are in your sales team?” The better response is simply to stay where the pain is.

What makes onboarding difficult?

How long has it been a problem?

What happens because new employees take so long to ramp?

Who feels the impact first?

What have you tried already?

Those follow-up questions are where discovery happens.

Too many founders believe discovery is about collecting information. It isn’t. Buyers don’t need another interview. They need someone who genuinely understands the challenges they’re facing. Your role isn’t to tick boxes in a qualification framework. Your role is to uncover what actually hurts.  

This is also where curiosity becomes one of the most underrated sales skills a founder can develop. Good founders aren’t afraid of silence. They don’t rush to fill every pause by talking about their product. They wait. They ask another question. They encourage the customer to tell another story.

Almost every important insight I’ve uncovered during a sales conversation arrived in the sentence after I thought the customer had finished talking.

And most of the time, the best thing you could do is start a call with, “How can I help you?” And listen.
