Building a GTM Hiring Plan After Series B
By Daniel Bryant · 20 July 2026
Most Series B founders I speak with have the same instinct: raise the round, then flood the top of funnel with account executives. It feels logical. More reps, more pipeline, more revenue. But after placing hundreds of GTM candidates into B2B SaaS companies across Australia and globally, I can tell you this instinct is almost always wrong.
The companies that scale well after Series B don’t just hire — they sequence.
Why Hire Order Matters More Than Headcount
After a Series B raise, B2B SaaS companies should sequence their go-to-market hires carefully: start with a RevOps Manager to build the data foundation, then hire Sales Engineers and an Implementation Specialist to support deal complexity and onboarding, followed by Account Executives to drive pipeline, and a Customer Success Manager to protect net revenue retention. Getting this order wrong leads to churn, wasted quota capacity, and founder burnout.
I’ve watched companies burn through eighteen months of runway hiring six AEs before they had a single process documented in their CRM. No lead scoring. No handoff workflows. No onboarding playbook. Those AEs either churned out or underperformed because the infrastructure wasn’t there to support them.
Your Series B board deck probably has a slide showing planned headcount by quarter. Throw it out and rebuild it based on operational readiness, not investor optics.
The First Five Hires — In Order
Here’s the sequencing I recommend to every founder scaling a GTM function post-Series B. This isn’t theory — it’s pattern-matched from real placements we’ve made at Zionic Group.
Hire 1: RevOps Manager
Before you add a single revenue-generating head, you need someone who owns the operating system. Your RevOps Manager builds the data layer, defines pipeline stages, sets up attribution, and creates the reporting your leadership team will live in for the next two years. Without this person, every subsequent hire operates in the dark. I wrote about the importance of RevOps as a strategic function — it’s not a support role, it’s a force multiplier.
Hire 2: Sales Engineer
If you’re selling technical products (and most B2B SaaS at Series B stage is), your founder or CTO is probably still jumping on demo calls. That doesn’t scale. A strong Sales Engineer unblocks your existing pipeline immediately. They increase win rates on deals already in motion. This is the fastest ROI hire you can make.
Hire 3: Implementation Specialist
The gap between closed-won and time-to-value is where deals go to die. An Implementation Specialist ensures new customers activate properly, which directly protects your net revenue retention. If your onboarding is messy, it doesn’t matter how many deals you close — you’ll leak revenue out the back end.
Hire 4: Account Executive (your first dedicated AE)
Now you hire your first Account Executive. Not before. By this point, you’ve got clean data, technical pre-sales support, and a functioning onboarding process. Your AE can actually sell effectively because the machine around them works. One great AE with infrastructure will outperform three AEs in chaos.
Hire 5: Customer Success Manager
With customers landing and activating properly, you need a Customer Success Manager to own expansion and retention. This person drives upsells, manages renewals, and becomes the voice of the customer back into product. Hiring a CSM before you have a reliable onboarding process means they spend all their time firefighting instead of growing accounts.
The Common Mistakes I See at This Stage
Hiring AEs first. I’ve said it twice and I’ll say it a third time. Quota-carrying reps without infrastructure underneath them is the single most expensive mistake Series B companies make. You’re paying base salaries, ramp periods, and opportunity cost while your RevOps and onboarding functions don’t exist yet.
Treating SDRs as the default entry point. Some founders jump straight to hiring SDR/BDR teams to build pipeline. But if your ICP isn’t clearly defined and your CRM isn’t configured to track conversion properly, you’re generating noise, not signal. SDRs are a scaling hire, not a foundation hire.
Ignoring the mid-funnel. Everyone obsesses over top-of-funnel (lead gen) and bottom-of-funnel (closing). The mid-funnel — technical validation, solution design, proof-of-concept support — is where complex B2B deals are actually won or lost. That’s your SE and your implementation motion. Neglect it at your peril.
Conflating urgency with speed. Your investors want to see ARR growth. That pressure is real. But hiring fast without sequencing correctly means you’ll be restructuring the team in twelve months. I’ve seen it dozens of times. Hire deliberately now so you don’t have to hire twice.
Build the Machine Before You Feed It
The best GTM teams I’ve placed into aren’t the biggest — they’re the most intentional. They sequence hires based on what the business actually needs at each stage, not what looks good on a headcount plan.
