03STRATEGIES & TACTICS

HOW TO MAKE FRIENDS BEFORE FUNDRAISING

Most founders start meeting investors the week they start raising, so every coffee turns into a pitch. A former YC partner explains how to build those relationships months ahead so the eventual raise is fast and competitive. The list is bigger than founders think, since more than 4,700 Series A rounds since 2023 were led by about 2,400 different funds. One tactic is to script every intro ("we're not raising, and I want to meet you because of the company you backed") so the meeting doesn't accidentally start a process.

ANALYTICS HAS CHANGED. HERE'S WHAT TO DO ABOUT IT

Software stopped having near-zero marginal costs once AI features started showing up on the bill. Analytics has to change now that agents both run the analysis and use the product. Agents now create about half of PostHog's dashboards and feature flags, so the team tags every event with whether a human or an agent did it. The same tagging shows a third of orgs query PostHog through agents, and 1 in 5 new orgs signs up through one.

PRESENTING AN ANNUAL PLAN (AI-ERA EDITION)

AI can make an annual plan look leaner before any of the savings show up. The fix is to put AI spend right beside the headcount plan and show when avoided hires or extra output will hit the numbers. Revenue needs the same split, because usage-based AI products can carry very different margins from the subscriptions next to them. Give the AI cost of free trials and proofs of concept its own line too.

THE SAAS APOCALYPSE STARTED IN OCTOBER

AI-built competitors are the easy explanation for any SaaS slowdown this fall. Stripe benchmarks covering about 181,000 subscription businesses show 29 of 48 groups above $100,000 ARR shrinking in October, up from four in September. Customer churn went down over the same stretch, leading the writer to suspect weaker new sales. Only companies above $5 million ARR were still growing in October.

WHO OWNS THE INTELLIGENCE ECONOMY?

An AI that learns from your best salesperson can keep using their methods after they leave. Companies need to decide who owns that expertise before model providers end up controlling it. Keep workflows portable between providers so switching models doesn't wipe out what the company's AI has learned.
