YC STARTUPS ARE SKIPPING THE API AND SHIPPING AN MCP SERVER

36.1% of YC companies with an MCP server have no public API. 36.2% in the 2025 and 2026 batches served an llms.txt. The public API share has barely moved across batches. 81 of the 5,635 reachable YC domains are listed in the official MCP directory.

THERE ARE NO MORE MOATS. YOU NEVER HAD ONE

Companies are buying more software than ever, but there's no loyalty anymore. They leave the moment something better ships. Migrations are now free, and contracts are monthly. Companies need to have the best product for the week, and then do it again next week. It's no longer about protecting a moat, but going out on the attack.

INTRODUCING FAST SEARCH IN THE PERPLEXITY SEARCH API

Fast Search runs on a Rust-based retrieval and ranking service called Photon that Perplexity built with a small team of engineers and hundreds of agents. It returns 95% of search results in 230 milliseconds or less. Fast Search has a median latency of 160 milliseconds, and it spends less on compute on ranking than Perplexity's default preset. Photon now handles all of the retrieval and ranking across Perplexity, replacing the open-source engine the company was using before.

INTRODUCING THE IMAGE & VIDEO API

ElevenLabs' Image & Video API allows users to generate images and videos with the same ElevenLabs API used for speech. It supports 18 models, including Veo 3.1, Seedance 2.5, GPT Image 2.5, and Nano Banana Pro. The API is available today on Pro plans and above. Generations cost the same credits as in the ElevenLabs app, and failed generations aren't charged.

WHY VENTURE DUE DILIGENCE GOT WORSE FOR DEEP TECH

Venture due diligence for deep tech has worsened, driven by deployment pressure, herding behavior, reliance on lead investors' reputations, and the removal of independent expert review layers. Deals in frontier tech sectors like AI and quantum often close rapidly without thorough technical vetting, exposing investors to unverified risks. Limited partners are advised to mandate independent technical feasibility reviews before deep-tech investments to enhance diligence and protect their capital.

WHAT IT TAKES TO BUILD GREAT PRODUCTS NOW

Getting there fast doesn't mean you've built something great. Teams need to decide whether a direction is the best, whether the product fits the team, and whether the product is worth building. The teams answering those questions well are strong in speed, direction, and differentiation. They'll keep moving through the final stretch, weigh many directions before betting on one, and shape the result into something only they would make.
