leadstreet review
CRM implementation, Onboarding, Migration · Ghent, Belgium · Since 2013
leadstreet has worked on HubSpot since 2013 and puts the line 100% HubSpot focus directly under its headline, which is HubSpot. Done right. It is run by three managing partners, Johan Vandecasteele, Johan Vantomme and Michel Antonise, and registered as leadstreet BV at Dok-Noord 5/1 in Ghent.
The service list covers setup and onboarding, marketing and sales strategy, service portals, web design, migrations and synchronisation, reporting, paid search and analytics, marketplace themes and modules, and custom app development. It also sells its own HubSpot add-on, PocketKnife, and publishes documentation for its themes and modules on a separate help site.
The benefits page is written against the objections a buyer hears internally, including we can handle it internally, it is too expensive, and another agency manages our marketing. On that last one it says it frequently collaborates with existing agencies, taking the technical implementation while they keep the marketing strategy.
Who leadstreet is for
Belgian and European companies that want the technical side of HubSpot handled by one supplier while an existing marketing agency stays in place. The site says that arrangement is common for it, which is a useful thing to know before the first call.
Migration buyers are well served: there are dedicated pages for Salesforce, Microsoft Dynamics, Pipedrive and Teamleader moves, and the reviews on its listing name a Salesforce migration specifically. The Dutch, English and Spanish versions of the site carry the same service structure.
Strengths and limits
Strengths
- Publishes a full set of terms and conditions, which is where the subcontracting, intellectual property and fee indexation clauses can actually be read
- States a single focus on HubSpot and backs it with dedicated migration pages for Salesforce, Dynamics, Pipedrive and Teamleader
- Says plainly that it works alongside a client's existing marketing agency, taking the technical implementation only
- Sells and documents its own themes, modules and the PocketKnife add-on, with a separate help site for each
Limits
- Its terms keep intellectual property in the deliverables with leadstreet, so what the client can reuse afterwards is a contract question, not a given
- The same terms let it appoint subcontractors of its own choosing, and add a non-circumvention clause with a fixed EUR 50,000 penalty per breach plus EUR 500 a day
- Client counts disagree across the site, with 700+ on the homepage and elite partner page and 650+ on the contact page
- No price, rate or minimum engagement is published, and the terms allow an annual fee adjustment indexed to a wage cost formula
leadstreet pricing
There is no rate card. The nearest thing to a price statement is on the benefits page, which argues that partner implementation typically costs the same as HubSpot's own standard onboarding while including the hands-on setup HubSpot's version leaves to your team.
The terms fill in the commercial mechanics instead. Additional work is quoted as a fixed amount or run on a pre-agreed hourly rate. Quotations stay valid two weeks. Invoices fall due in thirty days, late payment carries 1% a month plus a 10% indemnity, and fees may be adjusted once a year using a formula tied to Agoria Digital reference wage costs.
No rate or package price is published. The benefits page states that partner implementation typically costs the same as HubSpot's standard onboarding while including hands-on setup. The terms allow additional work on a fixed amount or on a pre-agreed hourly rate, and permit an annual fee adjustment indexed to Agoria Digital reference wage costs.
Licences, the build, and whose hands
Does it earn on your licences
Does not say whether it earns on your licences
We found nothing on its site or in its terms about whether it resells HubSpot licences or is paid on the software it recommends. That is recorded as silence, not as a finding against the firm. Ask before the first invoice.
Who owns the build
Says it keeps rights in the work
“All Intellectual Property Rights in the Product, including all trademarks, signs and logos used in the Product, shall remain vested in leadstreet at all times.”
Who does the work
Reserves the right to use third parties
“The Customer acknowledges and accepts that leadstreet may engage subcontractors of its own choosing to perform its obligations under the Agreement.”
This records what leadstreet publishes about itself, read in September 2026. It is not an assessment of what the firm does in practice.
Verdict
A European company that wants a technical HubSpot supplier and already has a marketing agency will find this one is set up for exactly that split, and says so. Publishing the full terms is genuinely useful, because most of the questions a buyer should ask are answered there rather than left to a first call.
Read clause 24 before signing. Intellectual property in the deliverables stays with leadstreet unless something else is agreed, subcontracting is reserved at its own discretion, and the non-circumvention penalty is EUR 50,000 per breach. None of that is unusual in Belgian agency terms, but it does need negotiating rather than assuming.
