Lecture 19 - Sales and Marketing; How to Talk to Investors (Tyler Bosmeny; YC Partners)

Sales: Getting from Zero to the First Customers

Tyler Bosmeny’s central point: founders—not just future sales hires—need to sell. In the early stage, founder passion and knowledge of the customer’s problem can outweigh formal sales experience. Sales is also a way to learn from users and improve the product.

Founder-Led Sales Funnel

• Prospecting: Find people willing to consider a startup’s product.
  • Early adopters are a small share of the market: Bosmeny cited Everett Rogers’s estimate of 2.5% innovators. Treat early prospecting as a numbers game.
  • During the first two months of YC, he contacted more than 400 companies.
  • Use personal networks, targeted conferences, and concise cold emails. For conferences, get the attendee list in advance and schedule meetings before traveling; go where target customers gather.
• Customer conversations: Listen more than you pitch.
  • Ask why the prospect took the meeting, how they solve the problem today, and what an ideal solution would look like.
  • Bosmeny’s rule of thumb from observing top salespeople: aim to speak about 30% of the call and let the customer speak about 70%.
• Follow-up: Keep pursuing a clear outcome.
  • A deal may require many emails, calls, and other steps—even when the customer is interested. Follow up persistently, but prioritize getting to a yes or a no; an indefinite “maybe” consumes time.
• Closing: Negotiate and sign without letting process overwhelm progress.
  • Redline agreements as needed, but avoid prolonged disputes over minor clauses. Early deals can provide revenue, validation, and reference customers.

Common Sales Traps and Recommendations

• Building a requested feature on a single prospect’s promise: Treat “we’d buy if you built this” cautiously. Ask for a signed agreement tied to delivering the feature, or wait until multiple customers request it before building.
• Free trials without commitment: A free trial may create activity without revenue or validation, and can mean having to sell the customer all over again afterward. Bosmeny suggested annual agreements with a 30- or 60-day opt-out as an alternative.
• Over-investing in high-touch sales for a low-priced product: Match sales effort to price and customer volume. A high-value enterprise product can support a more intensive sales cycle; a low-priced product sold to many businesses needs a repeatable, scalable process.

The early goal is to win customers, even through unscalable founder effort. Then identify which parts of the process can be repeated and scaled. Price and sales model must fit the kind of business the company aims to build.

Talking to Investors

Michael Seibel emphasized that a stronger company makes the pitch easier: traction and a good product matter more than presentation polish. His advice was to explain the business simply and briefly.

Pitch Framework

• 30-second pitch: three sentences
  1. What the company does, in plain language (the “mom test”: could your parent understand it?).
  2. The size of the market.
  3. Traction—such as growth, sales, revenue, or users. If pre-launch, show how quickly the team is building and shipping.
• Two-minute pitch: add four points
  • Unique insight: Explain the “aha” or competitive advantage in about two clear sentences.
  • Business model: State plainly how the company expects to make money. Avoid listing several speculative monetization options.
  • Team: Highlight relevant accomplishments; otherwise, be concise about founders’ roles, technical capacity, commitment, and how they know each other.
  • Ask: Know the fundraising instrument, terms, amount, and minimum check size. Be prepared to state these directly.

Seibel advised against rehearsing long pitches: the more a founder talks, the more chances there are to confuse or alienate an investor. Give the concise pitch, then let the conversation develop.

Fundraising Process

• Raise when possible with more traction rather than less. If the company is early, show momentum through a committed, full-time team and rapid progress.
• Avoid making the business dependent on an investor’s money before it can move forward. Seibel said most startups can get a product to market with relatively little money.
• Seek warm introductions, preferably from entrepreneurs or existing investors.
• Run fundraising as a sprint: arrange investor meetings in parallel and, where practical, cluster them in the same week. One suggested scheduling tactic was to propose meeting a few weeks out while the team focuses on building.
• Have one team member lead fundraising so it does not distract the entire company.
• After meetings, follow up. Dalton Caldwell’s closing rule was that anything short of a check or wired funds should be treated as not yet a commitment.
• Do due diligence on prospective investors, just as you would when hiring someone or choosing a business partner.
• Do not confuse fundraising with company success. Keep building the company rather than raising continuously.

Investor Role-Play: Lessons from the Examples

The first mock pitch was vague about the product, market, traction, business model, and team. It relied on comparisons to large messaging companies, withheld specifics, and did not make a clear ask. The lesson: if founders cannot clearly discuss their numbers or explain the business, they may not be ready for the meeting.

The second mock pitch was more effective because it grounded the product in real customer situations, shared what the team had learned, explained traction and potential distribution, described the team, and made a specific fundraising ask. Caldwell highlighted the value of a coherent narrative, concrete customer insights, and a clear close.

The role-play startup reported:

• 350 business locations across the San Jose–San Francisco area after about three months.
• 11% weekly growth in businesses acquired.
• An average of 1.5 messages per location per day.
• More than half of messages were practical questions (such as hours or availability), rather than feedback—an unexpected product insight.
• Small businesses had shown willingness to pay about $50 per month; the team cited large-enterprise feedback tools at $3–4 million per year as a separate potential market.
• The founders said small-business customer acquisition economics were difficult, and discussed either moving upmarket or partnering with consumer platforms for distribution.
• The mock ask was $500,000 on an $8.5 million convertible note, with $250,000 committed; the team said it was closing the round that Friday.

These figures were presented in a mock investor meeting, not as independently verified company results.
