Fundraising Fundamentals

Geoff Ralston explains how founders can prepare for fundraising: build a clear, credible story about the company’s opportunity, research investors, practice the pitch, and raise when the company is in a strong position. He covers how much to raise, valuation, dilution, SAFEs and equity, and the different roles of angels and venture capitalists. He also offers practical advice for investor meetings and negotiations, including listening, seeking feedback, reading every document, and avoiding over-optimizing the deal. He closes by emphasizing that fundraising is a step toward building a lasting business, not the goal itself.

Startup Investor School Day 4

Ron Conway describes how he moved from founding a computer company into full-time angel investing, and why he chose Internet software as a high-growth sector. He teaches investors to evaluate founders for character, determination, and how co-founders work together, while meeting the whole team and learning the company’s culture. He recommends spreading investments across a portfolio, adding value through hiring and introductions, and accepting that many investments will fail. He also urges investors to act with integrity and transparency, support founders’ execution without taking over their companies, and encourage civic engagement.

Startup Investor School Day 2

Dalton Caldwell explains how investors can build a clear process for evaluating startups, from setting a budget and qualifying companies to deciding when to invest or pass. He argues for independent criteria and personal conviction, and warns against groupthink, indecision, ghosting founders, and making commitments without following through. He recommends founder meetings that begin with basic questions, focus on listening, and assess trust and growing conviction. A mock meeting with Necto illustrates how to understand a complex business, while the Q&A covers practical fundraising and investor situations.

Startup Investor School Day 1

Carolynn Levy and Kirsty Nathoo explain how Y Combinator’s SAFE works as an early-stage investment instrument, including its valuation cap, conversion math, and what happens in acquisitions, failures, or when a company stays private. They walk through a cap table example to show how options pools and later investment affect ownership. They also cover signing and reviewing SAFEs, protecting investor rights, and modeling possible outcomes. Their closing advice is to support founders, tolerate pivots and failure, and be patient.
