HubSpot-first, no RevOps
“I've hired for GTM, but there's no system”
The one feature you need sits a HubSpot tier up, or in a tool you would be paying for that feature alone, and the rest of your stack already does the job.
Full-stack product engineering
When the GTM system needs a feature your tools don't have.
Sometimes the system needs a feature none of your tools has: a custom action on your own HubSpot app, an adapter for a vendor the templates don't support yet, a tracking schema nobody wrote down, a tool that puts a post into a queue with one click. A GTM engineer builds it as a custom module, from the template and modules we have already run in production, the same ones every other line is built from. Scoped per project after the Stack Audit, with a fixed fee and a timeline.
Who this is for
The feature you need is one tier up, one vendor over, or not for sale.
Ecosystem sellers and agencies
“We run this for others”
Your buyer is an agency plus a brand plus an event, or a franchisor plus a group plus a location, and no CRM object models that. The relationship lives in a spreadsheet, and “who do we know there” is a research project.
Product-led SaaS
“We have signups, not pipeline”
Your product, your website and your CRM each key people differently, and which events exist and what they mean lives in people's heads and an event list that grew by accident.
What we build
The same system, one more piece.
One system, cut from the template
Every line's work lands in one system in your accounts, cut from a template and assembled from modules, and a feature we build for you goes in beside them with the same config, tests and conventions.
Instrumentation and the tracking schema
Which events exist, what they carry, how people and accounts are identified and what each name means becomes one file in your repo, rendered as the tracking plan your engineers install from and as typed helpers that fail the build on a misspelled event.
An adapter for the vendor your stack needs
When your stack needs a vendor the Stack Audit's plan lists as an add-on, we build the adapter as part of your project, probed on a live key before it is promised, and you keep the keys and the account.
A capture tool
A capture tool puts a post a rep is already reading into the listening queue with one click and does nothing else: it never scrolls, searches or fetches, and your people do the posting.
An internal UI when a registry outgrows a spreadsheet
Anything your team maintains by hand starts as a spreadsheet or a doc that code compiles and checks, and when one outgrows that it gets a small internal tool of its own, in the same app, with the same checks.
What you're left with
One repo. Any TypeScript engineer can maintain it.
In your repo
The system and the feature are one repo in your name, with the version of the template it was cut from recorded, so an improvement to the template arrives as a pull request you can read, merge or decline. Every key and token in it is yours; nothing of GrowFlex's is in your environment.
In your CRM
Whatever the feature writes to a record follows the convention every module keeps: what it decided, why, the evidence and when, on fields your lists and workflows can use, and it starts as a dry run your team reads before anything is written.
GrowFlex-operated, on this line
Warehouse
Involved only if you have no warehouse of your own and the build writes reports or history you want kept in one.
What you receive at exit
pg_dump and CSVsA full export, or the warehouse re-pointed at your own database and backfilled.
Where judgement sits
Scope on paper. Code you can read.
- Scope. A scoped build has a written scope, a fixed fee and a timeline before work starts. What is not in it is a second proposal, not a surprise.
- Changes. Every change lands in your repo as a pull request with tests, so you can read what changed and why, and roll it back.
- The same every run. If a tool should be deterministic code, it is. Agents are used only where reasoning is required. Where a feature needs one, its output is typed and its input is stored, so the decision can be audited.
- Maintaining it. The repo is written for any TypeScript engineer to maintain. You can keep us embedded as your GTM engineer, hire your own, or hire a team to run it.
Scoped build
Start with the Stack Audit.
This line has no fixed entry offer. The work is scoped per project, estimated after a Stack Audit.
Typical timeline: 1 week
Stack Audit
For the team that has three tools doing a third of the job each and nobody who owns the whole.
- What we do
- We map every job each of your current tools does and where they overlap, sample your CRM's health, recommend the split, and propose one first offer in a scoped plan.
- Day-one deliverable
- The written audit, a one-hour readout, a fixed-fee proposal for the next step.
Questions
Questions we hear first.
Why not an agency, or a freelancer?
Either can write the feature. What they start from is a blank repo, and what you get is a one-off that sits beside nothing. A scoped build here starts from the template and modules we have already run in production, the ones every other line is built from, so the feature sits beside the suppression gate, the field convention and the reports, and the next piece composes with it. The HubSpot Tier Bypass is the small case: a custom action on your own HubSpot app instead of a tier upgrade, and the same action is how every later piece gets triggered from your CRM.
What do we own when it's done?
Repos, accounts, config and data are yours; three GrowFlex-operated tools, listed with their exit terms. All three, with what each holds and what you receive at exit, are listed on How it works, linked from the section above. The one this line may involve is the warehouse, listed above under how it runs after we leave, and a scoped build involves it only where its proposal says so, up front. Every vendor account is in your name, so the keys and the spend stay yours, and if we vanished tomorrow the system would still run.
How is it priced?
As a fixed scope with a fixed fee and a timeline, in the proposal that follows the Stack Audit. There is no menu: the audit's readout recommends one first piece for your stack, and the proposal prices it. Vendor spend stays yours and is reported, never marked up.
