Workbook for learning financial modeling and excel techniques

Giff Constablelean, startups

I’ve written about financial modeling for startups on here a few times, and included a few sample models. More recently, I led an after-work class internal at Neo for those interested in improving their skills. For those into lean, doing a thoughtful financial model from scratch is one of the best ways to spot hidden but critical assumptions, risks and …

Slack’s Success and Silos vs Teams

Giff Constabledesign

(Note: I’m going to leave the original post as-is, but I don’t think I wrote it very well, so see the addendums to prevent misunderstandings. Maybe. This is the Internet after all.) I read a blog post today that shocked me. A design agency taking credit for their client’s success. Which was surprising unto itself but what was more surprising …

The challenge of a hedging model

Giff Constablestartups

A couple days ago, I wrote about entrepreneurship and some level of partial hedging. Actually solving that challenge is, of course, enormously difficult. So much so, that I think it might only really be doable when companies are just starting out, and the equity is worthless. I can see it working in a startup studio that creates its own companies …

The Stupidity of Entrepreneurs

Giff Constablestartups

I was hanging out tonight with a bright young man who said, “A great entrepreneur always bets on themselves.” Context: we were talking about hedging. I asked the question: what if founders could hedge themselves against other startups so that if your company failed, you still had a chance for upside? He disagreed. He felt that a great founder would …

Why You Don’t Split Your Innovation Teams By Stage

Giff Constableinnovation

(this post originally appeared on the Neo blog) Andy Weissman of Union Square Ventures wrote a piece the other day on chaos theory and startups. His conclusion was that making decisions, and deciding how you make decisions, is of the utmost importance. There are many approaches to making decisions. My current thinking can roughly be described as “lead with vision, …

Do Market Sizing Early, Before You Jump Into “Lean”

Giff Constableinnovation, startups

Powerful new ideas often start with a spark insight: “Carpooling sucks! How can we fix it?” Or “Wow, these new smartphones might allow me to disrupt the entire taxi industry in a way never before possible!” Lean is great, but before you jump ahead with customer development, experiments and MVPs, it is worth taking two preliminary steps: 1. examine the …

Custdev – Everyone Does It. Full Stop.

Giff Constableresearch

I see a lot of product teams try out customer development at the beginning of their product journey. But quickly the team gets so busy shipping features and they outsource customer learning to customer support, research or usability specialists, or the sales force. Those are all valuable touch points, but custdev is not a task that product teams should ignore. …

The Value Behind Faster Horses

Giff Constabledesign, lean

David Bland has a funny, and painful, graphic called the Product Death Cycle. It clearly illustrates one of the more dangerous parts of customer development: taking customer ideas literally. The famous line attributed to Henry Ford goes, “If I had asked my customers what they wanted, they would have asked for a faster horse.” Some people take that as an …

Lean Startup Doesn’t Need Tools

Giff Constablelean

In 2012, we were testing a bunch of new business ideas for Amex and I thought, “what if we had a tool that let us capture our assumptions, our experiments, and our progress?” So over a couple weeks, we hacked something out and tried it out on a few projects. It was a complete waste of time. Here’s what lean …

Death to Clickbait

Giff Constablemisc

I’ve decided I’ve had it with blogger clickbait, in particular the tendency to toss a highly controversial title in front of a non-controversial post. The ones I fall for usually claim that something I believe is wrong (or “dead”). Then they proceed to explain how the idea was right after all, albeit in need of “tweaking.” I click because I …
