The most interesting thing about a consulting firm is rarely its own operations. For Tactical Advisory Group (TAG), a ten-year-old management consultancy based in Leuven, Belgium, that internal operation became the wedge for a product. The firm, which specializes in project management and business analysis for sectors like energy, healthcare, and telecom, built a software platform called Nimbus to manage its own consultants [TAG - Tactical Advisory Group]. Now, it is positioning Nimbus as a standalone system for other secondment and consulting firms, a move that attempts to productize a decade of service delivery into a repeatable software sale [TAG - Tactical Advisory Group]. It is a classic services-to-software pivot, executed from a position of quiet, bootstrapped stability rather than venture-fueled hype.
The wedge is the house
TAG's founding story is a familiar one in the consulting world: a group of consultants from larger firms broke away in 2014 to start their own shop, aiming for a more hands-on, engineering-focused approach from day one [TAG - Tactical Advisory Group]. The firm grew to an estimated 66 employees, with a focus on deploying trained engineers to solve client problems in logistics, planning, and digitalization [RocketReach] [TAG - Tactical Advisory Group]. As the team scaled, the internal friction of managing a growing roster of consultants on client projects,scheduling, skills matching, billing, reporting,presumably grew with it. Nimbus emerged as the answer, combining elements of an ERP, an Applicant Tracking System (ATS), and a CRM into a single platform tailored for the secondment model [TAG - Tactical Advisory Group]. The bet is straightforward: if this system works for us, it will work for other firms like us.
A product built from service scars
The value proposition for Nimbus is rooted in the specific pain points of a people-based services business. It is not a generic project management tool. It is built to handle the lifecycle of a consultant, from recruitment and onboarding through assignment, performance tracking, and client invoicing. TAG's public description of the platform emphasizes this integration, suggesting it eliminates the need to stitch together disparate systems [TAG - Tactical Advisory Group]. For a potential buyer, the appeal is that the software is informed by real, daily use at a firm of meaningful scale. TAG Managing Partner Peter Verboven and his team are essentially selling their own operational playbook, automated.

The realistic competitive set
TAG's ideal customer profile is clear: it is the managing partner or operations lead at a European secondment or technical consultancy firm with between 50 and 250 consultants. These are firms large enough to feel the pain of spreadsheet-based operations but not so large that they are locked into a global SAP or Oracle implementation. The competitive landscape for Nimbus is fragmented.
- Generic HR & Project Tools. Platforms like BambooHR, Monday.com, or Asana can be configured for similar purposes, but they lack the native workflows for consultant placement, rate cards, and client project profitability that are built into Nimbus.
- Industry-Specific PSA Software. Larger professional services automation (PSA) vendors like Kimble or FinancialForce target big consulting arms and system integrators, often carrying a price tag and complexity that overshoots a mid-sized secondment firm.
- Homegrown Systems. Many firms still run on a patchwork of spreadsheets and basic databases, which is precisely the problem Nimbus aims to solve. TAG's advantage is specificity. The risk is that the market for a product this focused may be narrower than the total addressable market for its consulting services.
Where the wheels could come off
The primary challenge for TAG is the classic services-to-SaaS transition: channel conflict and organizational focus. The firm's revenue and reputation are built on billable hours and client outcomes. Selling software requires a different sales motion, support model, and success metric. There is no public data on how many external clients have licensed Nimbus, or what portion of TAG's overall revenue it represents. Furthermore, the platform's success is tied to the continued health and relevance of the secondment business model itself, which faces pressures from remote work and the gig economy. TAG must prove it can sell Nimbus as a product to strangers, not just as a testament to its own internal efficiency.
The next twelve months
The watch points for TAG are concrete. First, the firm needs to start publicly naming reference customers for the Nimbus platform outside its own walls. Second, it must define a clear pricing and packaging model,is it a per-consultant SaaS fee, an implementation project, or a hybrid? Finally, the market will look for signals of investment, either in a dedicated product and engineering team for Nimbus or in external funding to accelerate its growth. A ten-year-old, bootstrapped consultancy has earned the right to move deliberately. But the clock on a pure product bet starts ticking the moment it is offered to the market.
