The honest framing
The big consultancies — Slalom, Accenture Song, Avanade, ICF, Coherent, and the rest of that tier — exist because certain engagements genuinely require their shape. They employ thousands of consultants. They have global delivery centers. They've done your industry's exact transformation thirty times. When the engagement matches what they're built for, they're the right call.
We're a 7-person senior core based in Charlotte. We don't do what they do. We do what they don't.
Pick the big consultancy when:
- The work touches 100+ systems. A multi- year cloud migration, an ERP rollout, a global identity consolidation. These engagements live or die on coordination, not on engineering speed. The headcount math is the value
- You need a single throat for $50M+ over multiple years.Big consultancies carry the contractual risk that comes with engagements at that scale. We're not the right counterparty for those numbers
- The deliverable is change management. Training 5,000 employees on a new platform. Running organizational design workshops. Building governance frameworks. Big firms have purpose-built practices for this. We don't
- You need 200 hands on the keyboard simultaneously. Some launches just require raw headcount. If you're replatforming a Fortune 100 retailer in six months, you need an army. Hire one
- The procurement requirement is “Tier 1 Microsoft Partner” or similar gates.Some buyers — federal, large healthcare, certain finance — can't legally engage outside of approved vendor lists. That's a real constraint
Pick ACM when:
- The work is one or two product surfaces, not fifty. A new SaaS product, a SharePoint estate cleanup, a mobile app for members, a brand platform rebuild. Scope that fits a small senior team in 4–12 weeks
- You want the person you talked to on the call to also be the person typing. No partner-to- associate-to-consultant relay. A named senior engineer on the call, the same named senior engineer in your repo
- The price needs to be the price.Fixed fees, no scope-creep games, no surprise change orders. Published numbers, signed SOW, that's the bill
- You need AI-accelerated delivery in the actual workflow, not in the marketing copy. The senior engineer pairs with Claude Code and Cursor every hour of every day. The compression is real
- You're mid-market, not Fortune-500. The $7,500–$100k Sprint range and $20–$50k/mo retainer are calibrated for 50–500 employee businesses, not for the kind of engagements that start with an eight-figure budget
The crossover case
Sometimes the engagement starts as one shape and turns into the other. A big-consultancy program runs into a custom build that's too small for them to staff cleanly — they bring us in as a subcontractor. Or a small ACM build expands into a multi-team rollout and we honestly recommend that the next phase go to a bigger partner. Both happen. Neither is a failure mode. The honest answer is whoever ships the next thing best.
The fit-call question
When you're evaluating any consultancy — us or anyone else — ask:
“Who, by name, will be writing the code? How many years of senior-engineering experience do they have? What's their day-one start date?”
At ACM the answers are: a named senior engineer, 10–18 years, Monday of week one. At a big consultancy the answers are often: “we'll assign the right team,” “ramping team will join in week three, steady-state in week six.” Neither answer is wrong for the right engagement. Both are useful signals.
Pick the shape that matches the work. If you're still not sure which side of the line your project falls on, that's exactly what the Fit Call is for.
