Wattcrunch
Know your solar numbers before you call an installer
About
Wattcrunch provides a set of browser-based calculators covering solar system sizing, projected electricity bill savings, payback period and return on investment, solar production potential by street address, net metering economics, time-of-use rate optimization, backup power/battery sizing, and side-by-side comparison of installer quotes. It also hosts a searchable database of federal, state, and utility-level solar incentives. None of the tools require creating an account or providing an email address.
According to the site, Wattcrunch was built as an alternative to solar calculators that function primarily as lead-generation tools for installers and that, in its assessment, overstate potential savings. As an example, it points to the expiration of the 30% federal residential solar tax credit (Section 25D) on December 31, 2025, which it says many other online calculators continued to apply after the fact.

Bending Spoons runs 600 people across a growing portfolio — that's operational leverage tech has never seen
Crowley breaks down the Bending Spoons playbook as extreme operational leverage: a fixed elite team of ~600 runs an ever-growing portfolio by applying shared infrastructure, pricing expertise, and marketing systems to each acquisition. The 97% staff reduction isn't business destruction — it's elimination of redundant overhead. The surviving business runs leaner with more resources than it had before.
I always start by running ads it's always the first thing I do so I do it on Google and meta depending on the product sometimes it's better on Google sometimes it's better on meta it's the fastest way to validate and test the market and as soon as I get some traction with ads I move to the second part of the growth which is SEO
Run Ads First to Validate Fast Then Compound With SEO
Samuel sequences his growth channels deliberately: paid ads give immediate signal on whether people will pay, and only after that signal arrives does he invest in the slower-compounding SEO channel. This order prevents wasting months on SEO for a product that never converts.
There's a play for whatever you're stuck on.
