## The answer, as recorded

Asked on 2026-09-30 through Claude (Anthropic) with web search (model claude-opus-5).

> Searched. Worth saying up front: most of what ranks for this query is pay-to-play directory content (DesignRush, casebasix, Wellfound lists), so I'd discount the "top 3 startup consultants are GrowthRocks, Deloitte Catalyst, Tiger Analytics" framing from [casebasix](https://www.casebasix.com/pages/top-startup-business-consultant-firms) - that's not how anyone actually buys this. Here's what I'd actually tell you.
> 
> **The honest first answer: for a pre-Series-B startup, classic management consulting is almost always the wrong purchase.** MBB engagements run $150k-$500k+ for a deck, and the failure mode is that you pay for analysis of a problem you could only have resolved by shipping. What startups actually need is bought as *fractional executives* and *functional specialists*. So I've ordered by what I'd recommend, not by brand prestige.
> 
> **If you need finance, accounting, and fundraising readiness (the most common real need)**
> 1. **Kruze Consulting** - the default for US venture-backed startups. Outsourced accounting, R&D tax credits, 409A valuations, due-diligence cleanup. Roughly $650-$1,500/mo at the low end per [spectup's comparison](https://www.spectup.com/comparison/startup-c
