Probably more context needed, but, the ones I played in my career thus far, likely ranked by NPV:
• Solo Engineer / Small Agency - CEO/CTO, has direct spending authority
but also is price sensitive, the product must be net productive at 5x-25x the cost, otherwise fee comes out of pocket. Values his/her time, but has an acute awareness when products don't pay for themselves. Example products I use(d):
Toggl.com,
Youtrack.com,
Gitlab.com
• Senior Dev - typically a W2 full-time-employee somewhere, codes in spare time to keep sharp on technology stacks that are going to help him in his career. Very little time, but typically paid well thanks to FAANG effect. Tools need to be polished, he/she is spending his money, but can recommend products to his employer (but they would likely ignore him). Example products: JetBrains (Kotlin), LeetCode
• Staff Engineer / Engineering Manager / Engineering Director at Fortune500: Comes in two variants, can be an excellent internal ally, but.. you need to know which variant you're dealing with.
◦ Variant A: Jumper/Fast Riser. Product needs to be sexy and pay off quickly (before his bosses forget about this), long-term value to business and liabilities are someone else's problem: Github Copilot, VR/AR modeling..
◦ Variant B: Retire-In-Place. Product needs to
not get him fired, and make his job easier. Typically buys IBM/Oracle/Microsoft, but will evaluate new products
if they are recommended by business/accounting, even if the products aren't great.
• Capitalizable Startup Founder (different than the Solo/Agency above): Not default alive, so every hour counts a lot more than money. He will buy products and services that save him time, even if they are not great - templates, landing pages..
