Close the deals.
Open the markets.
Fractional sales leadership for consulting firms and B2B SaaS scaling past the original sales motion. Embedded with your team — done with them, not for them.
B2B sales engines

Powering my workflows
Three ways
to grow.
Every Sprint focuses on one of three areas. We pick the right one in the Diagnostic.
Commercial Development
Build the sales engine
When a handful of people still close every deal and the pipeline lives in their heads. We build the outbound motion, qualification, and weekly cadence your team can run themselves.
- ICP & named target accounts
- Multi-touch sequences your reps send
- Qualification framework & pipeline stages
- Documented sales motion the team runs
Partnership Program
Channel as a second engine
When direct sales caps your reach and partners are the next lever. We design the program, agree the terms, and ship the first co-selling deals.
- Partner profile & value proposition
- Commercial terms & deal registration
- Recruitment & onboarding motion
- Co-selling enablement materials
Market or Vertical Entry
Open the next geography or segment
When the offer works at home and you need to land it somewhere new. I run the entry end to end — mapping, positioning, and the first qualified targets through the door.
- Market landscape & competitor mapping
- Localised positioning & offer fit
- Entry channel & sales-model design
- First qualified targets in seat
Tooling and AI, not as buzzwords.
Two things every Sprint installs, regardless of the focus area — because the lever doesn't hold without them.
Custom sales tooling
Engineered, not bought. The CRM, dashboards, and sequencers your team opens every morning.
- Notion or HubSpot CRM with stage definitions your team agrees on
- Pipeline scorecard auto-built weekly — Healthy / At Risk / Stuck rubric
- Outbound sequencer wired to your CRM (Smartlead, Apollo, or homegrown)
Applied AI for sales
AI where it earns its keep — research, prep, and personalisation. Not first drafts shipped raw.
- Pre-call dossier prompt that pulls LinkedIn + news in 30 seconds
- First-touch email drafts scored against your last winning outbound
- Discovery scoring and objection-handling library refreshed per ICP
Three phases. One focus.
Every Sprint moves through three phases — setup, operate, optimize. Embedded with your team on one focus, in the loop start to finish.
Setup
Get oriented, ship the first motion
Re-scope from the Diagnostic output, agree on the focus, set the operating cadence with your team. First version of the motion shipped early.
Operate
In the trenches with your team
Embedded with your people, running the motion alongside them. Sequences shipped, pipeline rituals live, deals moving. I'm joining calls, writing copy, coaching daily — not advising from the side.
Optimize & decide
Iterate what works, decide what's next
Refine on the strongest signals, kill what isn't compounding. We close the engagement with a clear call on what's next — handoff to your team, or a Continued Engagement to keep operating together.
20+ engagements across Europe and Southeast Asia.
A detailed look at six — consulting firms and B2B SaaS that opened new markets and built the channels behind their growth.
A repeatable way to win new projects
An established Singapore consulting firm was winning work almost entirely through the partners' existing relationships and referrals — no system to source new projects, no pipeline visibility beyond the next few weeks.
Built the commercial engine from the ground up: defined a sharp ICP and target-account list, designed a multi-touch outbound motion, set qualification criteria and a staged pipeline so opportunities could be tracked and forecast — then documented it so it runs without a partner driving every deal.
Project pipeline now visible 90 days out and sourced through a documented motion — partners no longer chasing every lead personally.
Expansion into the Singapore market
A Bangkok-based consulting firm was strong on home turf but had no route into neighbouring markets — and no read on how its offer would land with Singapore buyers.
Ran the market-entry work end to end: mapped the Singapore competitive landscape and buyer segments, adapted the positioning and offer to local buying behaviour, built the target-account list and outreach sequences, and set up the sales motion to land and service the first clients.
Servicing the first Singapore clients, with a localised offer and an outreach the team runs without me.
Opening Southeast Asia for an Italian manufacturer
An Italian company in the steel industry had a solid European business but no foothold, network or channel anywhere in Southeast Asia.
Built the regional go-to-market: analysed market dynamics and demand across the target SEA countries, defined the entry channel and sales model for the product and deal size, identified and qualified the first distributor and direct-account targets, and laid the commercial groundwork to start winning business.
First qualified distributor and direct-account targets engaged across the target SEA countries — commercial groundwork in place to start winning business.
A partnership program for a payments platform
A Bangkok payments SaaS was growing through direct sales alone — leaving channel leverage untapped and capping how fast it could reach new merchant segments.
Designed and stood up a channel partnership program from scratch: defined the ideal partner profile, built the partner value proposition and commercial terms, created the recruitment and onboarding motion with enablement materials, and set up deal registration and performance tracking so the channel could scale without conflict.
Channel program live and signing partners — distribution no longer capped by direct-sales bandwidth.
An integration partnership program
A Paris SaaS company needed distribution by embedding its service inside other applications — but had no partnership motion, no target-platform list, and no framework to structure the deals.
Built the integration partnership program: prioritised target platforms by user-base fit and strategic value, shaped the technical and commercial offer for integration partners, and built the process to pitch, sign and onboard them — turning integrations into a repeatable distribution channel.
Integration partnerships now a repeatable distribution channel — first platforms shipped, the process for adding the next ones documented.
Full-cycle sales leadership
A B2B SaaS backed by a major European banking group needed hands-on sales leadership across the full cycle.
Currently running the end-to-end sales motion: pipeline generation and qualification, multi-stakeholder deal navigation, and closing.
Ongoing — running the end-to-end motion alongside the founders and helping them decide the right time to bring it in-house.
