# GTM Fuel

> Fractional GTM engineering for B2B software teams. GTM Fuel joins a team a few days a week and builds the data, signals and internal tools that tell reps who to call and why. Based in Helsinki, working with teams across the Nordics and Europe.

GTM Fuel is a small GTM engineering studio run by Mikhail Kaltyshev through Justvibing Oy (Helsinki, Finland). The site is a single page at https://gtmfuel.com. This file is the plain-text version of it for language models and agents.

## What GTM Fuel does

Applied systems thinking for go-to-market, wherever the pipeline needs it. Four areas of work; a client may need one of them or the whole chain:

1. **Market**: TAM research and account sourcing. The segment mapped end to end, including companies no database lists. Not a purchased list; a picture of the market the client sells into.
2. **Signals**: Signal monitoring. Job changes, funding rounds, hiring spikes and stack changes, caught the week they happen, not a quarter later. Every signal is a reason to call and the line to open with.
3. **Data**: CRM hygiene, automation and scoring. Duplicates merged, gaps filled, stale records retired; then scoring that ranks who is worth a call, and workflows that route them to the right rep. No spreadsheet in between.
4. **Apps**: Custom internal apps that fit the team's workflow, built on the client's own data or external data. Examples: a sourcing pipeline with a review screen, a pricing calculator, a one-click enrichment run.

Not offered: outbound campaign execution. If someone only needs outbound campaigns run, GTM Fuel will point them to an agency that does it well.

## Who it is for

Good fit:
- B2B SaaS and tech-led consultancies past product-market fit, roughly €1M+ ARR. Nordics and Europe.
- GTM and RevOps teams that own pipeline and are tired of duct-taping tools together.
- Teams that have figured out their market (a strong hunch or actual product-market fit) and now need extra hands for the projects piling up.

Not a fit:
- Pre-product-market-fit companies or under €1M ARR. They still need to test angles and find their ICP, which is a different job.
- Anyone looking purely for outbound campaigns.
- Teams that want a hands-off vendor. Someone on the client side has to own what gets built.

## How engagements work (draft terms)

Three ways in. These terms are a working draft and may change.

**Hands-on: embedded GTM engineer**
- 2-3 days a week, inside the client's team. GTM Fuel builds the market map, the signals, the CRM and the tools the reps work in.
- Term: three months to start, then rolling.
- You get: shipped systems, documented, handed over running.

**Advisory**
- 1-2 working sessions a week. The client's team builds; GTM Fuel sets direction, reviews the work and unblocks it.
- Term: month to month, stop any time.
- You get: decisions, reviews, playbooks, and someone to call when it breaks.

**Enablement: team enablement**
- 2-4 working sessions a month for teams feeling behind on new tooling. Brings the team up to speed and clears the specific problems in the way.
- Term: booked as a block of sessions; extend or stop after each block.
- You get: a team that runs the new tools itself, with the blockers solved along the way.

All three start with a fifteen-minute call, then a scoped first month or block.

Everything is built in the client's own tools, so it stays theirs after the engagement. All that is needed to begin is a CRM and an enrichment layer. If the client does not have them yet, GTM Fuel helps pick and set them up together with the team.
