Overview
Instart Logic built an endpoint-aware content delivery and application-acceleration platform using its nanovisor JavaScript virtualization layer to optimize web and mobile performance, ad viewability, and security. The company raised through Series D with backing from Andreessen Horowitz, Greylock, and Kleiner Perkins. Akamai acquired customer contracts and select IP in February 2020 for approximately $36.4M; the standalone company dissolved.
Why Instart is interesting
Instart's nanovisor JavaScript virtualization optimized mobile web performance — Akamai bought the customer contracts for ~$36.4M after $80M+ in venture funding, a cautionary infra exit.

Competitive landscape
Edge: Endpoint-aware optimization via JavaScript virtualization — differentiated from traditional CDN caching at the time of peak mobile web growth.
CDN and edge markets consolidated around Cloudflare, Akamai, and Fastly. Instart's JS virtualization was novel for mobile web but couldn't sustain independent scale against incumbents with broader product suites.
