We build the revenue system your
sales, marketing and service team runs on.

For B2B services firms and SaaS companies: a pipeline your partners trust, every fee earner briefed before the meeting, and AI you can put in front of a board. Governed, and on the HubSpot you already pay for.

Built by an ex-EY change consultant and an ex-HubSpot specialist. Canberra, Australia.

From the system we run our own firm on

If you lead growth at a firm, you've thought one of these.

Three partners are talking to the same client and don't know it.
Cross-practice visibility
The pipeline report takes a week to build and nobody trusts it.
Reporting the board believes
The board wants AI. Our CRM data would poison it.
AI readiness

We build the revenue system your firm runs on.

Seicho is the team that puts a real pipeline under your firm. We clean up the CRM your partners gave up on, shape HubSpot around the way you actually win and deliver work, and add AI that drafts the updates, briefs and follow-ups, so your people spend their hours on clients, not admin. We do the build. Your team owns it. We stay close enough to keep it sharp.

A pipeline you can see

One source of truth your partners actually use, so the next big deal never lands as a surprise.

Briefings, not busywork

Every fee earner walks in prepared, with the AI doing the prep instead of chasing your team for data entry.

AI you can defend

Every change proposed, approved by a person, and logged. The kind of AI you can put in front of a board or a probity adviser.

It's not the models. It's governance and adoption.

Most AI projects fail for ordinary reasons. The data underneath them is wrong, nobody is accountable for what the AI changes, and the team quietly stops using it. 88% of AI pilots never reach production, and almost none of those failures are about the model. The fix is unglamorous: clean data, clear rules about who approves what, and a system your team actually adopts. That's where we work.

The 10-20-70 rule: where AI effort actually goes

10%
The AI itself
20%
Data and technology
70%
Process, people and adoption

Most teams buy the 10% and skip the rest. We build the other 90% around it.

AI with an audit trail.

Nothing touches your client records without a decision and a record of who made it. Every change works the same way.

01 · Suggest

AI proposes

The AI reads your calls, emails and records, then proposes a change: update this deal, brief this partner, fix this contact. It proposes. It doesn't act.

02 · Review

Your team approves

A named person on your team sees the suggestion, the reasoning, and the source. They approve it, edit it, or reject it. The decision is theirs, in one click.

03 · Apply

Change is logged

The approved change is applied and written to a permanent log: what changed, who approved it, when, and why. If anyone ever asks, you can show them.

Start with the Revenue System Audit.

Fixed fee · Two weeks · Under four hours of your team's time

Find out if your CRM can support growth and AI, before you spend another dollar on either.

Two weeks inside your HubSpot. We assess your data, your pipeline process, your stack, and your exposure if AI were switched on tomorrow. You walk away knowing exactly what's broken, what it costs you, and what to fix first.

A scorecard across data, process, stack and AI readiness
A prioritised roadmap with dollar impacts, not a slide deck of ideas
A live readout with your leadership, delivered by Jack

Fixed fee

$4,500

Proceed to a build within 30 days and the full audit fee comes off the price. The audit is the first step, not an extra cost.

Who this is for. And who it isn't.

We do one thing well, and we'd rather tell you upfront than waste your fortnight finding out.

A strong fit if you are

A B2B services firm or SaaS company, roughly 30 to 300 people
Running HubSpot, or committed to moving onto it
Accountable to partners or a board that needs numbers they can trust
Under pressure to "do something with AI" and unwilling to do it carelessly

Not a fit if you want

Whole-of-business automation for a company under about 20 staff. Good operators do that work; we'll point you to one.
AI writing to your CRM unsupervised. We won't build it, on principle and on evidence.
A provider to run your systems for you forever. Your team owns everything we build.

Asked on almost every call.

Yes. We work with B2B services firms and SaaS companies of roughly 30 to 300 people running HubSpot. If you're outside that, or you want whole-of-business automation rather than a revenue system, we'll say so on the first call and point you to someone who fits better. We'd rather lose a sale than take on work we can't do well.
It stays in your HubSpot, in your accounts, under your access controls. We work inside your environment under NDA, we don't copy client records to our systems, and nothing you give us is used to train AI models. When an engagement ends, our access ends with it.
Everything. Workflows, integrations, prompts, configuration and documentation all live in your accounts and belong to you. If you parted ways with us tomorrow, the system keeps running. We're removable by design.
Because you should know the cost before you commit, not after. The Revenue System Audit is $4,500, takes two weeks, and the scope doesn't move. If you proceed to a build within 30 days, the audit fee comes off the build price.
A full build is $30,000: Marketing, Sales and Service, built in parallel over 8 to 12 weeks. The audit confirms that fixed quote before you commit a dollar to it, and the $4,500 audit fee comes off the build. For professional services firms with several practices, we build the first end to end, then template and tune it across the others, so each additional practice costs and takes less than the first.
With numbers, not a pitch. The audit puts dollar impacts against the specific gaps in your pipeline, so the build is sized against the value it unlocks rather than a flat list of features. You go into the decision with a roadmap a CFO can read, the fixed price, and the audit fee already credited. If the impact doesn't justify the build, the audit will tell you that too, and you'll still keep the findings.
Not in anything we build for client records. Every change to a client record is proposed by the AI, reviewed by a named person on your team, approved, and logged. Low-risk housekeeping like formatting can be set to apply automatically, but you decide where that line sits, and it's documented.
The Revenue System Audit. Two weeks, $4,500 fixed fee, under four hours of your team's time. You receive a scorecard, written findings, a live readout with your leadership, and a roadmap with dollar impacts. Whether you build with us or not, you keep all of it.
We build governed AI: a suggestion engine your team approves, not an autonomous agent acting unsupervised on your CRM. If you're comparing the two, we've written about exactly where the line sits.
GTM engineering treats your revenue system as engineered infrastructure, not a CRM you configure and hope. Seicho is a GTM engineering studio: HubSpot, clean data, and governed AI wired together as the system your team runs on.

Growth you can see. AI you can defend.

The Revenue System Audit is two weeks, $4,500 fixed, and yours to keep either way. That's the whole pitch.
