The First 100 Days of PMI Have Changed Forever in the Age of Agentic AI

The monumental compression of time frames across all SOPs and workflows is in full motion globally. Private equity and mid-market acquisitions are no exception here.

➡️ It’s been 3.5 years since ChatGPT was introduced.

➡️ Just two months to reach 100,000,000 users.

➡️ The Internet took a decade to reach 100M users. Instagram needed 2.5 years. TikTok – 9 months.

Of course, ChatGPT alone is way past 1 billion monthly active users by now.

And that entirely excludes the full set of other LLM interfaces like Gemini, Claude, X, all of the APIs and MCP integrations, and core LLM-driven pieces of software already representing decacorns or higher: Cursor, Mistral, Perplexity, Harvey and Legora, Replit and Lovable, Runway, ElevenLabs, Synthesia.

Or AI-adopters in the enterprise – from Salesforce and HubSpot to Asana, Monday and Notion, to virtually every business trying to survive that peak. SaaS markets have been brutal and punishing the late adoption of outdated business models over the past 18-24 months, for a good reason. 📉

SaaS was disrupted.
Media was punished due to the lack of organic search.
Social is affected by zombie accounts and AI replies.
Service companies take a hit with compressed delivery times.
Recruitment is stalled as jobs look differently and juniors can’t be billed.

This week’s edition of GSI reviews the first 100 days post-merger, previously occupied by discovery, meetings, code reviews, documentation, mindmapping, journey planning.

This cycle is far more actionable, agentic, autonomous, practical – and requires work done in the first few weeks alone.
