Caldwell describes investors with finance backgrounds who tend to reach for money-based solutions, such as raising or spending more. He recalls being asked for five-year projections before product-market fit, when his immediate concern was that the company was losing money. Spending can help once a company is ready to scale, but it can also amplify weak unit economics and distract from improving the product.
Why Investors Can’t Fix Your Company
Speakers
Y Combinator partners Dalton Caldwell and Michael Seibel discuss why investors cannot fix a startup and how founders can use their advice.
Caldwell says executives from large tech companies can be strong at refining products and scaling teams, but early startups face a different challenge. Many fail by getting no real customers, and hiring executives before product-market fit may add departments where the actual problem is a poor team fit or unmeasured results. Scaling a product after acquisition requires different skills from finding its first users.
Seibel warns that investors successful in businesses like real estate or franchises may seek control that does not fit a tech startup. Caldwell says junior investors may strongly encourage fundraising and growth because a quick valuation increase helps their career. Influencers may offer promotion for shares, but founders can overestimate how much a post will solve distribution problems.
Caldwell says founder-investors often generalize from their own experience, while very young investors may repeat current trends. He also notes that YC's usual advice to launch an MVP and stay lean does not fit every company; some products need years of development before launch. Seibel and Caldwell say founders must judge what applies and own the work of making the company succeed.
Caldwell recalls an investor helping him by simplifying a confusing set of signals into a clear judgment about what was working or failing. Seibel shares how Gideon Yu congratulated Justin.tv on reaching eight million dollars in annual revenue, then warned that the company still needed major change. Seibel says that direct diagnosis helped, even without a prescribed solution.
Takeaways
- Before spending more, check whether the product is solving a real customer problem.
- Before hiring an executive, identify the specific gap that needs fixing.
- Treat investor advice as input shaped by the investor's experience and incentives.
- Judge fundraising and growth advice against your company's actual stage and evidence.
- Look for advisers who can clarify the problem, then take responsibility for the solution.
