    AI Native Startups Boost PR Output Tenfold

    In a detailed essay, software engineer Neil Kakkar compares his productivity across three companies: Bloomberg, PostHog, and Tano. At Bloomberg and PostHog, he shipped 8-20 pull requests per month, while at Tano, an AI-native startup, he now ships over 200 PRs monthly, an 11x increase. This surge is attributed to AI coding agents like Claude Code, which handle end-to-end feature development, automated code reviews, and continuous integration. Key trade-offs include loss of human code reviews, increased context switching, and 'thrashing' from multitasking. Tano operates without human PR reviews, relying instead on an automated reviewer agent. The author notes that AI is a speed multiplier, but requires culture shifts and guardrails to prevent burnout. The essay highlights that AI-native startups can iterate much faster, but pre-AI companies can catch up by adopting similar practices.

    • Neil Kakkar's PR output increased 11x at AI-native startup Tano compared to PostHog.
    • Tano uses Claude Code agents to build features end-to-end and an automated code review agent.
    • At Tano, PR merge time is less than one hour, and the revert rate is 6x lower than at PostHog.

    Build vs Buy: Cookie Banner for React/Next.js

    This technical guide compares building a custom cookie banner versus using a consent management platform (CMP) for React and Next.js applications. It argues teams should build their own banner only when requirements are narrow and the engineering team is prepared to maintain consent infrastructure over time. The article highlights key responsibilities of production consent systems — script gating, preference storage, withdrawal support, regional behaviour, and durable records — and presents c15t as a developer-first CMP that supports hosted, self-hosted, and browser-only deployments. Inth is named as a managed hosting provider for c15t. The guide stresses that script gating and backend persistence are critical when auditability and regulatory accountability (e.g., GDPR/UK rules) matter.

    • The article recommends building a custom cookie banner only if requirements are narrow and the team is prepared to maintain the logic over time.
    • c15t is described as a developer-first consent management platform that supports hosted, self-hosted, and browser-only deployments.
    • Inth provides a managed hosted deployment option for c15t teams that do not want to operate the backend themselves.
