I help founders build a sales engine they own, with AI built in.
Interim and fractional Head of Sales for founder-led B2B SaaS. I fix the pipeline, install the process, and put AI to work on research, call analysis, forecasting and team training. Then I hand it over and step back.
I've watched a lot of great products and companies fail.
The products were good. What went wrong sat around them, and the same four gaps kept coming up.
No CRM
The pipeline lived in a spreadsheet or in the founder's head, so nobody could see it.
No process
Every deal was handled differently, and every new rep started from zero.
Low conversion
Deals stalled and nobody could say where or why.
No growth goals
The team was busy, with no number to hit and no plan to hit it.
All four can be fixed, and fixing them early costs far less than fixing them late. That is what I do. I step in, build the system with your team, and leave it with them.
Sound familiar?
Maybe you're still the best salesperson in the building, and running sales yourself is taking a toll on product and marketing. Maybe your first AEs are in seat but not producing, and you can't tell whether it's the people or the system. Maybe a team lead is running the day to day and needs senior backup, or a sales leader just left and the gap is wide open.
Not sure which gap is yours? That is what the AI-GTM Diagnostic is for.
Two ways to work together
Interim Head of Sales
Your commercial function, run and rebuilt at near full-time intensity, then handed to your team. The fastest way out of founder-led selling and into a revenue engine that runs without you.
Fractional Head of Sales
Senior Sales leadership at lower intensity, ongoing, for teams that can't yet justify a full-time hire and aren't ready to commit to an interim. Light-touch ownership that keeps the engine improving, week after week.
AI that does a job in your funnel.
I spent a year studying AI at university in 1994, ran markets for a predictive-AI company from 2012 to 2020, and I build with it every day. In your sales engine it does four jobs.
Research
Account and market research that used to take weeks takes days, so your reps spend their time on the buyers who matter.
Call analysis
Your recorded calls are read for what actually loses deals: weak qualification, unhandled objections, vague next steps. The findings feed coaching.
Forecasting
Pipeline data and deal signals give you a forecast you can defend to a board, and flag the deals that are slipping before they slip.
Enablement and training
Playbooks, call scorecards and onboarding material built from your real calls, kept current, and usable by reps on day one.
Your team keeps the decisions. AI does the reading, the drafting and the counting.
HermitCRM
A free, local CRM for one person, for Mac and Linux. Pipeline board, calendar, contacts and timelines are kept as plain Markdown files on your own machine, and an MCP server lets Claude, ChatGPT or Cursor answer questions about your pipeline and log activity for you. I built it to run my own pipeline. It is alpha software, made for founders and solo sellers who have no CRM at all.
See HermitCRMThe Method
Hands on your live deals from day one. CRM and pipeline set up or cleaned up, qualification installed, deal stages rebuilt around real exit criteria. Growth goals set with you: a number, a plan, and the pipeline needed to hit it. AI reads your recorded calls and your market, so we see where deals actually leak.
Forecasting you can take to a board, with AI-assisted deal signals. A repeatable qualification and handoff. Coaching for the reps you have, driven by call analysis, and a partner channel where it fits your market.
A documented playbook, a forecastable pipeline, AI-built training and onboarding material, and a team that runs the engine without me in the room. Renew on a lighter footing, or exit clean.
The AI-GTM Diagnostic
One to two weeks, fixed scope, fixed fee, quoted after a first call. I go through your CRM and pipeline, your sales process, your conversion at each stage and your growth goals. I use AI to read your calls and your data for what the dashboard hides.
What you get
- Where your deals leak, with evidence from your own calls and numbers
- A forecast baseline and a growth target that fit your actual capacity
- A written 90-day plan you can run yourself, or run with me
What happens next. You decide. Run the plan with your team, bring me in as interim or fractional Head of Sales, or use it to brief a hire. If you bring me in, the diagnostic fee is credited against that engagement.
Your data stays under NDA and in your own tools. I tell you up front what is processed where, and I'll sign a DPA if you need one.
The results
I've taken revenue from early or zero to scale five times, across regulated SaaS, fintech, cybersecurity and recruitment tech.
People who've worked with me
“I worked with Gijs in the early days of Now Interact, when we were selling AI in 2014. Back then every AI deal was a Challenger sale. Gijs reads a situation, a tool or a process faster than anyone I have worked with, and he closed our first reference customers himself before he built the team that took it from there. If you need a Sales Leader productive in weeks instead of quarters, that is him.”
“I joined Now Interact with zero SaaS experience and Gijs took a chance on me. What followed was the best on-the-job training I’ve ever had: the customer lifecycle, what good deliverables actually look like at each stage, and above all a sense of commercial ownership that has stayed with me since. Any SaaS business that brings Gijs in, even on an interim basis, is getting someone who builds systems and people at the same time.”
“Gijs built the foundations of TryHackMe’s B2B sales function during the stage where we scaled fastest. He brought in the qualification, opportunity management and forecasting discipline the team needed to grow without breaking, and shaped how we sold rather than just what we tracked. I was an AE when he arrived. The process he put in is the reason people like me could step up.”
Gijs Bos
I'm not a consultant who ships slides. I run the function: I carry deals, sit in the forecast, manage the reps. You get an operator, not a deck. I've taken revenue from early or zero to scale five times across regulated SaaS, fintech, cybersecurity and recruitment tech, then handed each one over. Underneath it all sits an unusually long view on AI: studied in the mid-90s, eight years selling it before the current wave, building with it today, including HermitCRM, an open-source CRM of my own.
If your sales engine is the thing standing between this round and the next, let's talk.
