Alternatives
Sigma M&A alternative: Upswitch SaaS + advisory
Sigma M&A delivers classic full-service M&A advisory for Belgian mid-market SMEs (€2m–€50m EV); Upswitch combines SaaS speed with advisor-network distribution at materially lower cost for sellers under €25m EV.
What is it?
Sigma M&A is a Belgian M&A advisory boutique running the classic mandate model: retainer + success fee, dedicated deal team, IM/CIM authoring, buyer search, full process management from kick-off to closing. The practice covers Flanders + Brussels, with cross-border deals via a European network. Their strength: experience with complex family-business structures, union negotiations, and sectors where discretion is critical.
When Sigma M&A is the right choice
Sigma M&A is the right choice for: (a) deals above €15m EV where an experienced lead advisor with a dedicated team justifies the process cost, (b) businesses with legal, tax, or union complexity that requires more than tooling, (c) sellers who want exclusively one advisor carrying the full dossier — no Upswitch self-service step. For competitive auctions in the €15m+ band, an established firm like Sigma is often the right call.
When Upswitch is the right choice
Upswitch is the right choice for: (a) deals below €15m EV where a €25k retainer is disproportionate, (b) sellers who want to orient themselves first before engaging an advisor, (c) owners who want to validate the valuation with an independent engine before mandate negotiation, and (d) advisors who want to scale their practice with SaaS tooling — many Belgian M&A boutiques use Upswitch under the hood. The two models can coexist: Upswitch for valuation and initial listing, Sigma (or comparable firm) for the executive mandate above €15m.

Frequently asked
- Does Upswitch compete with M&A boutiques like Sigma?
- Not directly — many Belgian M&A boutiques use Upswitch under the hood for valuation and data ingestion. We make the mandate work more efficient; they do the work a tool can't: negotiating, reading signals, building trust with buyers.
- Above what deal size does a boutique like Sigma become unavoidable?
- From ~€15m EV onwards a dedicated deal team becomes hard to avoid. Below €5m, advisor + SaaS stack can fully suffice. Between €5m-€15m it's a process choice: how much bilateral effort + competitive tension do you want to orchestrate yourself.
- What if I'm torn between self-service Upswitch and a mandate?
- Always start with an Upswitch valuation. It costs nothing, gives you a defensible price anchor, and if you decide to mandate a boutique you negotiate from better information. Sigma's lead advisors will appreciate the preparation.
- Can an M&A boutique reuse my Upswitch run?
- Yes — the white-label PDF + audit trail is designed exactly to be co-signed by an advisor and used as an IM/CIM appendix. Many boutiques kick off a mandate by running an Upswitch valuation first.
