Building a startup is a learn-as-you-go endeavor, but that doesn't mean you have to learn everything the hard way. We've compiled the resources that our most successful portfolio founders have found valuable.
Fundraising
- Know your story before the deck — investors fund narratives, not slides
- Target 18-24 months of runway per round
- Talk to 50+ investors; expect a 5-10% conversion rate
- Get your data room ready before starting conversations
Hiring Your First Engineers
Your first five engineers set the technical culture for the next hundred. Prioritize:
- Generalists over specialists — they need to wear many hats
- Builders over architects — you need code shipped, not diagrams drawn
- Pragmatists over perfectionists — done is better than perfect at this stage
The Technical Interview We Recommend
Skip the whiteboard algorithm puzzles. Instead:
# Give candidates a real (small) problem from your codebase
# Time-box to 2 hours, async, their environment
# Evaluate:
# - How they decompose the problem
# - Code clarity and naming
# - What they test vs. skip
# - How they handle ambiguity in the spec
Product-Market Fit Signals
You have product-market fit when:
- Customers are pulling the product from you (not being pushed)
- Word-of-mouth drives >30% of new signups
- Usage increases organically without marketing spend
- Customers would be genuinely upset if you shut down
If you have to ask whether you have product-market fit, you don't. When you have it, you'll know — you'll feel like you're barely keeping up with demand.
