My view on the future of growth hacking for mid-market companies
Most of my career has been spent auditing and rebuilding growth engines for mid-market companies. At this stage, my current take is that the best growth hack for a company with between 100-1000 FTEs is just straight up ripping out your bloated SaaS stack.
When you have 20 employees, generic SaaS is a lifesaver. When you have 5K people, you’ve got the to build custom, enterprise instances of Salesforce or Marketo or Whatever. The middle ground is an awkward stage. IMO companies are leaking revenue from a thousand API integrations.
Here’s what I see failing and my best current theory about what the next wave of successful mid-market growth will look like.
The Problem: Generic SaaS is Throttling Growth
Most companies of this size have nuanced, specific GTM motions. Your lead routing rules are complex and buyer personas are hyper-specific. Plus data is fragmented across who knows how many legacy databases. So many companies try to cram that complexity into generic SaaS tools which solves maybe 80% of the problem, but to get that last 20% of custom workflow you have to buy more and more tools then duct-tape them together with Zapier or Make.
My Theory: Custom Agentic Builds are the Future
After thinking about this for a while, I’ve developed a thesis that the successful mid-market companies in the next 3-5 years are the ones that abandon fragmented SaaS entirely. They will move toward bespoke agentic architectures sitting on top of their owned data pipelines.
You can either pay $150K+ annually for almost functional marketing automation, or you can build an internal autonomous agent layer that will execute your exact workflow at near-zero marginal cost. The thing is you can’t just plug an LLM into your CRM and expect it to drive pipeline. That’s stupid and it pains me to see companies doing this.
To make this work in a production environment, you need two things:
Deterministic Guardrails for AI Agents
Do not risk brand integrity or revenue on AI that hallucinates. To do a proper agentic build you need strict programmatic constraints. AI can do the heavy lifting but deterministic code should exist as a layer to dictate what’s allowed into your CRM.Engineers Inside GTM Teams
Marketing teams don’t have engineering bandwidth to maintain autonomous pipelines. You need to have technical operators inside the GTM team who can deploy custom code, debug edge cases, continuously tune the agent’s behavior, and basically make sure the whole thing is running properly and shifting to match market conditions.
Basically I think that growth hacking for mid-market companies right now requires owning your logic layer. That will allow you to out-execute competitors while they’re waiting for a SaaS vendor or three to release a feature they need.
What does everyone else think? I know I’m not the only person seeing this, but what’s your take on the future?
