6 sales lessons from closing $100K startups to $1B+ enterprises

Founders who stay close to deals build better products and sharper positioning.

But most stop selling the moment they hire a sales team. That’s exactly when they should stay in.

Running sales personally across Europe, the United States, and even in Japan and Australia has meant occasional 12 am calls, 3 am contract negotiations, and 9 am–7:30 pm demo blocks. This gave me something no amount of pipeline reporting could: a real-time feedback loop on what closes, what doesn’t, and what customers want. 

Here are 6 lessons that came out of it.

Lesson 1: Know your competitors as well as your own product

Buyers are talking to 3–5 vendors at once. 

If you can’t say exactly why you’re different from the alternatives they’re evaluating, you’re leaving that comparison up to them. And they’ll fill in the gaps with whatever your competitor told them. 

I’ve had some demos where the person asks me if it’s true that AiSDR is less than 5 people set up in a backroom somewhere (fyi, our team currently has over 35 people). 

Study the competition the way you study your own product. Make sure you’re ready to pounce on any openings that pop up.

Know their pricing structures, their weak spots, and the objections their customers raise on G2. When a prospect names a competitor, respond with specifics. Generalities don’t close deals.

Lesson 2: Speed wins at every stage

Speed signals confidence. A fast follow-up after a demo says you’re organized and you want the business. A slow one says the opposite, regardless of your intent.

What “fast” looks like shifts based on who you’re talking to. 

In SMB, it’s a same-day follow-up with next steps and a calendar link. In enterprise, it’s a same-day recap email so that stakeholders can brief each other internally, and your written summary is often what gets forwarded. 

The mechanism is different, but the principle is the same: If you let time pass between touchpoints, you’re letting doubt grow. 

Move fast and keep moving.

Lesson 3: Add value every time you follow up

Speed is about timing, but what you say matters just as much.

“Just checking in” is a waste of everyone’s time. If you have nothing new to say, wait until you do.

Every touchpoint should give the prospect a reason to re-engage: a relevant case study, a stat tied to a pain point they mentioned, an insight from a call with a similar company. 

One sentence of genuine value beats a hollow nudge. The goal is to be the person they’re glad to hear from.

Lesson 4: Direct 3-option break-up emails can revive ~35% of ghosted deals

Prospects go quiet for a hundred reasons. And most of them have nothing to do with you. 

Sending more polite follow-ups won’t fix this. It’ll just slowly erode your credibility.

What works is a direct break-up email with 3 clear options: still interested, check back in N months, or not moving forward.

This gets a response because it removes the social awkwardness of saying no. In my experience, about 35% of ghosted opportunities come back when you make it that easy for them to reply.

Lesson 5: Find the methodology that fits you, then adapt it to the deal

MEDDIC, Challenger, SPIN, Sandler… These lead scoring frameworks all work in the right context. 

The mistake is picking one and applying it rigidly across every deal type.

SMB moves fast and needs low-friction closing. Too much time on discovery and you lose them.

Enterprise needs multi-threaded relationships and a longer discovery process. Deals can take weeks just to get qualified.

The best approach is to understand multiple frameworks well enough to blend them based on who you’re talking to and where you are in the cycle. Adaptability is a closing skill.

Lesson 6: Learn from the people around you, including your own team

The obvious move is learning from people above you. The less obvious move is learning from people at your own level or below, and it’s often more valuable.

As a founder running sales alongside my own AEs, some of my sharpest observations came from watching how they handled objections and navigated late-stage hesitation. 

They’re working deals every day. They see patterns before the playbook catches up. They’ll do what you’re sometimes hesitant to do.

If you’re leading a sales team, pay attention to what your best closers are actually doing, and not just if they’re doing what you told them to do.

Result

A 33–35% conversion rate across deal sizes doesn’t come from working harder. 

It comes from making sharper decisions at each step: knowing the competitive landscape cold, moving fast, making every touchpoint count, giving ghosted prospects a clear way back in, matching your methodology to the deal, and staying curious about the people around you.

Saving money on headcount isn’t why founders should stay close to sales. It gives you a free, irreplaceable feedback loop. Every deal carries a takeaway about your product, positioning, or market.
