I’ve been in your shoes—as a founder, operator, and investor—and I know getting from initial traction to Series A is harder than most admit. You need clarity, not more noise.

That’s why I built the Founder’s Companyon to Series A, a GPT trained on years of real-world coaching, investor insights, and GTM best practices. It’s designed to help you define PMF, escape hero-led sales, and prep for your raise with focus and confidence.

Let me show you how it works.

The Difference Compared to ChatGPT

So how is this different to just using standalone ChatGPT

Built for B2B Software from Seed to Series A

This GPT isn’t trying to serve everyone. It’s tuned specifically for the zero-to-one journey of B2B  founders navigating product-market fit, GTM repeatability, and raising with conviction.

Trained on real founder coaching — not just content

This isn’t just scraped content. It’s grounded in the firsthand coaching Parthib does with dozens of post-seed startups and the operator-investor lens of Companyon Ventures.

Speaks metrics like a board deck — not a blog post

From CAC payback and Sales Magic Number to retention cohorts and burn multiples, it explains what they mean, when they matter, and how to improve them — without watering it down.

 

Doesn’t bluff or guess — it sharpens your thinking

Generic GPTs often hallucinate. This one doesn’t speculate. If the input is unclear, it’ll ask better questions. If your logic is fuzzy, it’ll challenge you.

Built for dialogue, not just prompts

You don’t need to craft the perfect question. Start where you are — it guides the conversation, step-by-step, like a real coach would.

 

Anti-fluff, anti-hype, pro-conviction

This GPT strips away vanity metrics, aligns your KPIs to investor signals, and helps you tell a story that scales — no buzzwords, no filler.
