Hands-on advisory · pre-seed → seed · CEE

[In the trenches]
with founders.

We get in the trenches and run the workstreams alongside you — from narrative to capital — so the company can scale without losing its plot.

// the principlefounding belief · 2014→

We replace market theory with behavioural reality and ruthless focus on the real human behind the segment.

Most early-stage failure is a narrative problem dressed up as a product, sales, or capital problem. We start at the source — who this is for and why — and work outward through every system that depends on getting that answer right. No hand-offs, no decks left behind, no advice without execution.

Experience forged across enterprise and early-stage.

What we do.

narrative first → customer intel feeds everything → product + capital run parallel

Six workstreams covering every move from idea to seed. Not sequential — they run in parallel with a strict priority hierarchy. We embed across all of them, in founder voice, with the depth of a fractional C-level and the speed of an operator.

01 · narrative foundation
1ST · UPSTREAM

Narrative Foundation & Positioning.

The thinking everything else is built on. Before pitching, selling, hiring or posting — there's a working answer to who this is for, what the problem is, why now, why this team.

  • ICP definition
  • Problem framing in customer language
  • Category design — enter or define
  • Validated value proposition
  • Master narrative arc, deck-feeding
Outcomea story the founder owns under fire.
02 · customer intelligence
2ND · ALWAYS-ON

Customer Intelligence — a system, not a phase.

Validation is binary; intelligence is ongoing. We build the discovery rhythm that surfaces signal from interviews, deals, and churn — and routes it back into product, narrative, and sales.

  • Discovery architecture & respondent map
  • 15–30 structured interviews
  • Pattern recognition · affinity diagrams
  • Continuous loop · win/loss · churn autopsy
  • Cross-workstream insight brief
Outcomesignal that compounds, never dries up.
03 · product + revenue
3RD · PARALLEL

Product + Revenue Track.

Two tracks that stress-test each other. Product stays honest only when revenue says "yes" — and the sales motion only sharpens when product hears the objections live.

  • Problem-solution fit memo · MVP scoping
  • Build, kill, iterate
  • ICP-aligned prospecting · founder-led
  • Pilot-to-paid · first 10 deals debriefed
Outcomeretention curves and signed contracts.
04 · capital track
4TH · PARALLEL

Capital Track — a process, not an event.

Fundraising as continuous relationship-building. The deck is a leave-behind; the pitch is a conversation. We sequence outreach like a sales funnel and read between the no's.

  • Tiered investor mapping · A/B/C lists
  • Pitch from master narrative
  • Warm outreach sequencing & CRM
  • Live objection library · iterate per round
  • Term sheet → due diligence → close
Outcomecapital, on terms that don't haunt you.
05 · team & ops
ONGOING · TABLE-STAKES

Team & Org · Ops & Finance.

The risk floor. Just-enough structure to de-risk the business and support fundraising — without burning founder attention on infrastructure that doesn't matter yet.

  • Founder gap mapping · constraint-based hiring
  • Role scorecards · Topgrading-style interviews
  • Operating principles · decision rights (RACI)
  • Driver-based 18-month financial model
  • Clean books · cap table · data room ready
Outcomeinfrastructure that disappears into the work.
06 · marketing & visibility
LAST · NARRATIVE-GATED

Marketing & Visibility — earliest in temptation, last in priority.

Founder-led, narrative-gated. From credibility, point of view, and being findable by the right people to brand building, channel strategy and campaigns planning.

  • Narrative gate-check before any public output
  • Founder POV / category thesis
  • 1–2 channels
  • Repeatable content system + repurposing
  • Category awareness · speaking
Outcomepost less, say more — own the conversation.

How we work together.

We align the commercial model with what the startup actually needs. Three paths — pick the one that matches your runway and conviction. Numbers happen in conversation.

/ path 01

Cash

100% cash

A full monthly fee for companies prioritising a clean, cash-based engagement. Fastest to start, no dilution, no small-print.

Best whenRunway is healthy and the team wants pure service.
/ path 02

Hybrid

cash + equity

A split — typically 50/50, flexible from 20/80 to 80/20. Aligns incentives without stressing the burn. The most common path.

Best whenYou want skin in the game on both sides.
/ path 03

Equity

100% equity

Full equity. Reserved for companies we'd otherwise want to invest in ourselves — we're betting on the outcome alongside you.

Best whenCash is tight and conviction on both sides is high.

Who we are.
