The answer, as recorded

The right choice depends on your stage and budget. This is the order I'd give them in: **1. SCORE (free, US).** Start here. You get free one-on-one mentoring from 11,000+ volunteer experts through local chapters or online. It won't replace a senior executive coach, but it costs nothing and covers the basics well. ([GrowthMentor](https://www.growthmentor.com/blog/startup-coaching/), [M Accelerator](https://maccelerator.la/en/blog/entrepreneurship/best-places-to-find-startup-mentors/)) **2. Y Combinator Startup School (free).** This isn't coaching, but it's the best free structured program for pre-idea to pre-fundraise founders. It has a curriculum built on YC's experience, weekly progress check-ins and co-founder matching. ([startupschool.org](https://www.startupschool.org/), [Entrepreneur](https://www.entrepreneur.com/business-news/what-i-learned-from-y-combinators-free-startup-school/475335)) **3. MentorCruise or GrowthMentor (low-cost, on demand).** Good for specific problems like pricing, go-to-market or a fundraising deck. You pay a monthly fee and book one-on-one sessions with vetted operators, which costs far less than a coach on retainer. ([MentorCruise](https://mentorcruise.com/coach/startup/), [GrowthMentor](https://www.growthmentor.com/blog/startup-coaching/)) **4. Reboot (executive coaching for founders and CEOs).** This is the firm I'd name for coaching aimed at the founder personally: burnout, leadership, co-founder tension. Jerry Colonna co-founded it after years as a VC at Flatiron Partners and JPMorgan Partners, so the coaches understand startup pressure. It's expensive. ([Reboot](https://www.reboot.io/team/jerry-colonna/), [Wikipedia](https://en.wikipedia.org/wiki/Jerry_Colonna_(financier))) **5. Entrepreneurs' Organization (EO) peer forums (once you have about $1M+ in revenue).** These are member-led peer groups covering business and personal life. All-in cost is usually $4,400-$7,000 a year. Early-stage founders often get more from peers here than from a paid coach. ([EO](https://helloeo.org/resources/eo-vs-vistage/), [Leaders Adapt](https://www.leadersadapt.com/ceo-mastermind-comparison-2025/)) **6. Vistage (later stage, around $5M+ in revenue).** Groups are led by a professional chair, with monthly one-on-one executive coaching and structured accountability. It costs about $16,500 a year plus a $2,500 initiation fee, so it doesn't make sense for most early startups. ([Vistage](https://www.vistage.com/research-center/member-experience/vistage-vs-eo/), [Leaders Adapt](https://www.leadersadapt.com/ceo-peer-group-2025-guide/)) **7. An EOS Implementer or a Scaling Up certified coach (when you're building a team).** These coaches install a company operating system rather than coaching you personally. EOS suits companies with roughly $1M-$20M in revenue that need discipline and accountability. Scaling Up fits better above about 50 employees, or when cash and strategy are the problem. Before 10-20 people, both are probably overkill, and simple OKRs will do. ([Scaling Up](https://scalingup.com/scalingup-vs-eos-comparing-systems-implementation-costs/), [Tability](https://www.tability.io/odt/articles/okrs-vs-eos-vs-scaling-up)) **A few more points:** - **Cost:** Independent startup coaches usually charge $1,000-$5,000 a month on retainer ([Paperbell](https://paperbell.com/blog/startup-coach/)). - **How to choose:** Pick someone who has run a company like yours and listens before offering a framework. - **Who I left out:** "Best coaches" lists often feature big personal brands like Grant Cardone. I wouldn't pick them over the options above for a startup. - **Biased sources:** Some pages I used are written by the providers themselves, like Vistage's comparison, Scaling Up's comparison and Eric Partaker's own list of top coaches ([ericpartaker.com](https://ericpartaker.com/blog/7-best-executive-coaches-for-startups)). Take their claims about themselves with a grain of salt.
