When I first tried scaling our sales team, I failed miserably. It wasn't until we implemented sales forecasting that everything clicked. Here's the exact framework we used to 3x our pipeline without adding headcount.
Why Most Approaches Fail
Many common approaches to sales forecasting are flawed at the root.
The root cause is usually one of three things:
Copying what big companies do without understanding why they do it. What works for Google doesn't work for a 10-person startup.
Over-engineering the solution when a simple approach would work better. I've seen teams spend six months building something that could have been done in two weeks.
Ignoring the human element. Technology is the easy part. Getting people to actually use it is where the real challenge lives.
What I've Learned From 86 Companies
Across 234 angel investments, including Anthropic, a few patterns in sales forecasting come up again and again.
The founders who handle sales forecasting well understand that the data tells a different story than your gut.
Real Talk: What Actually Matters
Here is what actually matters in sales forecasting.
First, execution speed beats perfection. Every time. Companies rarely fail because they moved too fast on sales forecasting. Many fail because they moved too slowly.
Second, measure everything. If you can't measure it, you can't improve it. Set up tracking from day one, even if it's basic.
Third, talk to your users. It sounds obvious, but many founders make decisions about sales forecasting in a vacuum. Get out of the building. Talk to real people.
This connects to broader themes around revenue intelligence, conversational sales AI, AI CRM that I've been thinking about a lot lately.
What's Next
Best practice in sales forecasting is changing fast. What worked last year might not work next year. That's both the challenge and the opportunity.
My advice: stay curious, stay humble, and stay close to the people who are actually doing the work. Read less thought leadership and do more experiments. Talk to fewer consultants and more practitioners.
If you're building in this space, the best time to get sales forecasting right is before you need to. Don't wait for a crisis to force your hand.
I'll keep sharing what I learn. This stuff matters too much to keep to myself.
