Selling as a science: core principles from 30 years in enterprise sales

Executive overview

Most founders treat selling as persuasion. It's not. It's a structured process of enabling a buyer's decision-making journey.

The job is to understand the business outcome the customer is trying to reach, then help them get there. When a buyer sees you are genuinely invested in solving their problem, the sale follows.

Selling is a science, not an art — and the seller's role is to orchestrate a process, not pitch a product.

Talk less, listen more

• The 30% rule: speak no more than 30% of the time in any sales conversation.
• Buyers will tell you everything you need to know if you stop filling the silence.
• When someone says no, ask why before ending the call — they will engage.
• Rejection is a learning input, not a failure.

Selling as a structured process

• Ask for many small yeses throughout the buying journey, not one big yes at the end.
• Early-stage companies should test multiple decks and messages simultaneously to find what resonates.
• Process discipline separates companies that figure out how to sell from those that don't.
• The goal is never to sell someone something — it's to help them solve a problem.

Selling is a team sport

• No salesperson can win complex deals alone; you lead a virtual team across functions.
• Match the right expertise to the right moment: bring in a systems engineer, data scientist, or executive when the buyer needs it.
• Flooding a buyer with everyone at once is overwhelming; knowing when to plug in each player is a skill.
• Marketing, peer reviews, and reference materials are extended team members — the buyer is self-educating throughout.
• An executive personal commitment ("I will partner with you to make this successful") can unlock a stalled deal.

Product-led growth is still selling

• PLG replaces the salesperson with the product, website, and trial — but it is still a sales motion.
• The best technology does not automatically win; awareness, virality, and alignment to a stated problem matter.
• PLG works best in favourable macro conditions and for SMB or mid-market buyers who can self-serve.
• Enterprises have procurement layers, approval chains, and financial analysts — direct sellers are almost always required at that level.
• Channel partners and system integrators are an extension of the selling motion, not a separate activity.

Choosing where you are on the continuum

• Sales strategy is a continuum from pure PLG to direct enterprise selling.
• Where you sit on that continuum should match your current market, buyer, and stage — and it will shift over time.
• The question is never "great technology, who should buy it?" but "what problem am I solving and how do I expose that to the right buyer?"
