Hiring a GTM engineer
vs. building with Selleris

Compare a 12-month engineering budget. The pre-filled hiring and software figures are editable example assumptions, not market averages. Both routes need people to run sales and customer success.

Hire first

An in-house GTM engineer

Fund a person to design, build and maintain the system internally. Your scope, management and delivery risk remain in-house.

12-month scenario$164,400
Build first

Your selected Revenue Loop

Selleris builds the agreed capabilities in accounts you own. Your team runs the system. Hire into it when you are ready.

The budget difference$95,000 less in this scenario

The selected Build equals 4.4 months of the annual employment budget above, before tools and other costs.

This is a budget comparison, not a claim that a hire and a project deliver identical work. Day-to-day sales and customer-success staffing, taxes and unlisted integrations are not modelled. Provider budgets do not change automatically with module selection. An existing capability is reused only after validation. The hire-start selector is a cost assumption, not a promised delivery date.

[Implementation Cost]

What determines HubSpot implementation cost?

Your budget depends on what already works, data quality, integrations, process complexity, migration scope and team handover. The diagnostic turns those requirements into one fixed Build price. Software, data and future Improve work stay separate.

What already works

Usable CRM foundations, segmentation and workflows are retained after validation instead of rebuilt.

Existing equivalents can reduce the new Build scope.
Data quality

Duplicates, missing fields and inconsistent records change the preparation and validation work needed before automation is reliable.

Cleaner data means less remediation before launch.
Integrations

The systems to connect, their APIs and the direction of data flow determine integration effort and test coverage.

Provider fees stay separate from Selleris engineering.
Process complexity

The selected capabilities, routing rules, permissions and approvals determine how much must be built, tested and documented.

The diagnostic turns this into one fixed Build price.
Migration scope

The records, activities, attachments and historical relationships you need to preserve determine the migration work required.

Move what the new system needs, not every legacy record.
Enablement and handover

Documentation, training and acceptance checks are planned around your users and workflows, so your team can take over the system.

Included in the agreed Build scope, not a surprise add-on.
