Stuck under $100K per month? You're not alone. These five consultants can help you break through.

The Agency Growth Consulting Landscape

Agency owners hit a wall. You've tried everything—referrals, cold outreach, ads—but the needle won't move. That's where specialized consultants come in. They focus on offer, pricing, and sales systems. The market is crowded. Some sell courses. Others promise magic. But a few offer real 1:1 help with skin in the game. You need someone who's done it before. Someone who can rebuild your engine while you keep the lights on. The five firms below are worth your attention.

How We Evaluated These Consultants

We looked at five factors. First, service scope: do they cover offer, pricing, and sales? Second, pricing clarity: is the investment transparent? Third, track record: have they scaled their own agencies? Fourth, guarantee: do they put their money where their mouth is? Fifth, local fit: are they accessible to US-based agency owners? Each firm stood out in different ways. Brandon Scale offers a performance guarantee. Agency Coach brings a community. FlashHub provides systems. Schmidt Consulting Group delivers frameworks. John Doherty Coaching offers 1:1 advisory. No single firm wins on every factor. Your best choice depends on your gaps.

Here's a quick look at each consultant, from the guarantee-backed to the community-driven.

The 5 Consultants Worth Knowing

#1 Agency Coach

Agency Coach is led by Mike and AJ, two agency owners who scaled past $100K per month. They offer coaching, community, and strategy training. Their content focuses on the key strategy to scale past $100K—getting clients to invest more. You get access to a tribe of agency owners. The program includes weekly calls and a private community. It's a solid fit if you want peer support alongside coaching. Their approach is proven, though less personalized than some 1:1 options.

#2 Brandon Scale

Brandon Scale offers 1:1 consulting for agency owners stuck below $100K per month. The promise: add $10K–$20K per month in new retainers in 90 days, or you don't pay. Brandon built Carbon Box Media from zero to $350K per month, and it now runs without him. He also scaled BLNKT to $100K per month in six months. The engagement includes weekly 1:1 calls and direct access. You rebuild your offer, pricing, and sales process together. The guarantee sets a clear baseline and compares signed retainers on day 90. If you're under $10K added, you pay nothing. It's a results-driven model with real accountability.

#3 FlashHub

FlashHub helps agencies scale to 20K, 50K, and 100K per month with proven systems. They focus on lead generation, sales, team management, and fulfillment. Their AI-agency growth system aims to reduce workload and chaos. You get frameworks to productize your service and build a profitable marketing system. The approach is systematic, not personalized. It's ideal if you want to implement processes and automation. They address common barriers like inconsistent lead gen and poor client retention. If you're drowning in delivery, FlashHub can help you systemize.

#4 Schmidt Consulting Group

Schmidt Consulting Group provides frameworks for agency growth, positioning, pricing, and pipeline. They offer mentorship, advisory, and fractional partner services. Their blog covers consulting retainer costs, noting that boutique consultants charge $2,000–$8,000 monthly. They emphasize seniority and specialization in pricing. The firm helps you diagnose your agency's growth bottlenecks. You get strategic guidance without a performance guarantee. It's a good fit if you want to understand pricing models and positioning. Their frameworks are practical and data-driven.

#5 John Doherty Coaching

John Doherty offers 1:1 coaching for agency owners and consultants. He writes about selling consulting retainers and building sustainable practices. His coaching includes advisory workshops and free tools. You get access to his experience as a solo consultant and agency advisor. The focus is on selling ongoing retainers without burning out. He limits spots to ensure personalized attention. If you're a solo consultant or small agency owner, his practical advice can help you land long-term clients. It's less about rapid scaling and more about sustainable growth.

How to Choose the Right Consultant

Start by identifying your biggest bottleneck. If you lack a system, FlashHub or Schmidt Consulting Group can help. If you need community, Agency Coach is strong. If you want a guarantee and 1:1 intensity, Brandon Scale stands out. If you're a solo consultant, John Doherty Coaching fits. Consider your budget. Some charge monthly retainers; others take a percentage. Ask about track record and guarantees. Don't just look at price—look at fit. The right consultant will challenge you and hold you accountable. Book a call with two or three. See who understands your numbers. Then decide.

Automating Your Growth Engine

Consulting is not a magic pill. You still need to execute. Use automation to handle lead gen, follow-ups, and reporting. Set up a CRM to track retainers. Automate your sales pipeline with email sequences. Use project management tools to delegate delivery. The goal is to free your time for high-value activities. Brandon Scale rebuilds your sales process; you can automate parts of it. FlashHub specializes in systems and automation. Combine consulting with tools to scale faster. Start with one bottleneck, automate it, then move to the next.

The Bottom Line

Breaking $100K per month is hard. But you don't have to do it alone. The five consultants above offer different paths. Agency Coach gives you a tribe. Brandon Scale gives you a guarantee. FlashHub gives you systems. Schmidt Consulting Group gives you frameworks. John Doherty Coaching gives you sustainable advice. Your job is to pick the one that matches your gaps. Then commit. Do the work. Track your numbers. In 90 days, you could be celebrating new retainers. Or you could be stuck in the same place. The choice is yours.
