Y Combinator W16 Demo Day Story

Below is a post I wrote in August 2019 within Y Combinator community (which luckily received 300+ upvotes 🙇‍♂️). Now that I get a pretty steady stream of inquiries about fundraising and accelerator/demo days, I thought it might be helpful to repost here in public format. Hope it brings hope to a few.

API Economy and Software Engineering Productivity

One of the macro trends we’re seeing in the software industry today is the rise of the API economy.

As discussed in the management framework #2 — abstraction and reduction — API is analogous to hiring a good management layer in a company, to provide more leverage to the developer allowing productivity gain through an abstraction layer of software. This abstraction stage is a critical phase in any industry to grow exponentially, as in any complex-enough industry, building all of the value chain end-to-end becomes infeasible and the trade-off between control and speed/quality/resource gets exponentially larger.
