En Serio

What En Serio does

En Serio is a privately held, Amsterdam-based public relations and inbound marketing agency founded in 2009 by Eric Dragt. The firm specializes in technology communications for the Benelux market, serving B2B tech innovators across infrastructure (Juniper Networks, Colt, Leaseweb, Ciena), business applications (Tableau, SAS, Freshworks, Commvault), fintech (Stripe, iZettle), consumer technology (Netatmo, Prezi, OKI), and the broader tech ecosystem (Ironhack, rb2). Its core services combine earned-media PR with content marketing, social media management, and — since 2019 — HubSpot-powered inbound marketing delivered through publicly priced tiered packages (Inbound Start at €2,500/month, Next at €3,500/month, Growth at €5,000/month, plus custom engagements).

The agency's operating model is relationship-led rather than pitch-led: over its first seven years it acquired 45+ clients through referrals and existing relationships without competitive pitches. The team is small (~6 active consultants, with tenures of 15–25 years in tech PR) and is based at a single Amsterdam office. Differentiators cited in the firm's own materials are deep, long-standing journalist relationships in the Dutch/Belux media landscape, a combined PR + inbound offering, and B Corp-certified operating practices including a commitment of at least 5% of team time to pro-bono work.

En Serio monetizes exclusively through professional services fees: monthly retainers for inbound marketing packages and project- or retainer-based PR engagements for enterprise and startup tech clients. There are no disclosed funding rounds, parent companies, or external investors; the firm is founder-owned and privately held under Dutch law. Strategic priorities evidenced in the record include service expansion via the HubSpot partnership (2019), vertical extension into greentech/sustainability (2015 Investment Ready Program partnership; 2023 B Corp certification), and selective geographic expansion into Belgium and select Nordic/UK accounts.
