Trengo is a serious European unified-inbox platform. The question for HubSpot teams is whether you want WhatsApp to live inside HubSpot, or inside a second product at app.trengo.com.

✓
Yes. A completed WhatsApp Flow lands in HubSpot as a native form submission event, so existing form-submission Workflows fire automatically. |
✕
No. A Trengo Flowbot or Journey collects answers into Trengo's contact record and, optionally, logs a "contact moment" to HubSpot CRM. No documented path treats a WhatsApp interaction as a HubSpot form submission. |

✓
Yes. Structured replies map to HubSpot properties and can be branched on with standard HubSpot Workflow branches. |
✕
Branching happens inside the Trengo Journey, not inside HubSpot. HubSpot only sees the eventual outcome. |
| Bi-directional contact syncCompanies, Contacts and Deals stay in sync between HubSpot and the platform. |

Trengo is a credible Dutch unified-inbox platform with a real Meta WhatsApp BSP licence, 10+ channels and 3,000+ customers. Flowella takes the opposite architectural approach: WhatsApp lives inside HubSpot, with no parallel inbox or workflow engine to maintain.
Built in Reading, UK by Discover Digital, a HubSpot Solutions Partner. Flowella converts HubSpot Forms into WhatsApp Flows and writes answers back as native form submissions.
About Trengo
Founded 2017 in Utrecht by Patrick Meutzner, Marcel van de Weerd and Igo Trampe. $37.9m raised in total, including a $36m Series A in September 2021 led by Insight Partners and Peak Capital.1
Trengo's product is the inbox. WhatsApp conversations live at app.trengo.com, automations run inside Trengo Flowbots and AI Journeys (Beta), and HubSpot appears as a sidebar that shows Contacts and Opportunities inside the Trengo inbox. The Marketplace listing is labelled BETA.2 Flowella reverses the design: HubSpot is the system of record, WhatsApp Flows are built from HubSpot Forms in one click and submissions return as native form submission events.
If your operation is HubSpot-centred, Flowella keeps WhatsApp native to HubSpot. If your team wants Trengo to become the primary multi-channel workspace across email, WhatsApp, social and live chat, Trengo is a serious option.
You already use HubSpot Forms and Workflows. You want WhatsApp to capture clean, structured answers that trigger the workflows you've already built.
Choose Trengo if…
You have a team that lives in a shared WhatsApp inbox, runs broadcast campaigns, builds rule-based chatbots, and handles Instagram and Messenger too.
You want shared inbox replies and outbound templates from your HubSpot record, and don't need WhatsApp Flows, branching automation, or coexistence with the Business App.4
Four questions HubSpot teams ask when comparing a HubSpot-native WhatsApp layer with a separate Dutch unified inbox.
Yes, natively. A completed WhatsApp Flow appears in HubSpot as a native form submission event and can enrol the contact in any standard HubSpot Workflow with no glue code.
The equivalent path runs the other way round: the customer completes a Trengo Flowbot or AI Journey, Trengo writes the data to its own contact record, and then Zapier, Make.com or a custom webhook pushes the result into HubSpot. That works, but it leaves HubSpot's automation engine downstream of a second product.2
Yes. Flowella is designed around HubSpot's Conversations Inbox — where you need a shared WhatsApp inbox, connect HubSpot's native Conversations channel and Flowella handles the structured-form side.
No. Trengo's entire product premise is its own unified inbox at app.trengo.com. The HubSpot integration adds a sidebar inside the Trengo inbox that shows HubSpot Contacts and Opportunities; it does not push WhatsApp threads back into HubSpot's native Conversations Inbox as first-class engagements. Your agents work in Trengo, not in HubSpot.2
No. Flowella supports WhatsApp Coexistence via Meta Embedded Signup, so the existing WhatsApp Business App keeps running on the same number.3
Yes in practice. Once you migrate the number to Trengo as your BSP (per Trengo's own help-centre migration guide), the number is bound to Trengo's API and removes Business App access on that number. That is standard BSP behaviour, but it is a one-way door Flowella does not require.
Flowella Pro is $159/mo flat. No per-user fees. Meta delivery passed through your own Meta account at Meta's published rates. Predictable.
On Trengo you cannot buy 7 seats. Boost starts at 10 seats for €299/mo (annual, €349 month-to-month) but does not include the HubSpot integration. To unlock HubSpot you move to Pro at €499/mo (annual, €599 month-to-month), sized for 20 seats. You pay for 20 to use 7, plus Meta WhatsApp fees, plus AI Journeys and HelpMate at €0.25–€0.30 per AI conversation once the free tier is exhausted.7
Both products publish pricing. The difference is the model: Flowella is a flat HubSpot app subscription with no per-user fees; Trengo is conversation-based with fixed 10- or 20-seat packages, AI surcharges, and the HubSpot integration gated to the Pro plan and above.

Flowella Pro is $159/month flat, with no per-user charge and Meta delivery billed directly through the customer's own Meta Business Account.
Only the recurring base subscription is shown. Meta delivery is paid on top, and that's where the markup matters.

"Constant price increases, retiring critical features… I am disappointed by the inability to export my data, except through a complicated process involving the API; this feels somewhat like being held hostage."
"Our decision to transition away from Trengo stems from a staggering 270% price hike this month, escalating from €66 to €244, without any added value or enhanced features."
Quoted reviews are public customer feedback retrieved 16 May 2026. Trengo's overall ratings remain positive on G2 and Trustpilot; the quotes shown are representative of the pricing-transition friction recurring across 2024 reviews, not the only voice in the dataset.
Exceptional engagement platform that transformed our student conversion with a 160% increase in same-day applications and 90% WhatsApp response rates.

Straight answers for HubSpot teams comparing Flowella and Trengo.
Honest. Trengo is a serious, well-funded Dutch platform with a real Meta BSP licence, a mature unified inbox and a strong European customer base. There are three feature rows on this page (team inbox, multi-channel breadth, EU data residency) where we openly say Trengo is stronger. The page is structured to help HubSpot-anchored teams decide whether to keep WhatsApp inside HubSpot via Flowella or rebuild around Trengo's inbox; it is not designed to claim Flowella is better in absolute terms.
No. Trengo has Flowbots (its own chatbot construct) and AI Journeys (its own no-code journey builder, currently in Beta). Neither imports a HubSpot Form and neither is a Meta WhatsApp Flow. To trigger a WhatsApp template from HubSpot data, Trengo's documented path is HubSpot → Zapier or Make.com → Trengo Journey webhook → "Send WhatsApp template" block.5
Effectively yes. Trengo's product is the unified inbox at app.trengo.com. The HubSpot integration adds a sidebar inside the Trengo inbox showing HubSpot Contacts and Opportunities. WhatsApp threads do not flow back into HubSpot's native Conversations Inbox as first-class engagements. Your team works inside Trengo, not HubSpot.2
With Trengo, yes once you migrate the number; Trengo becomes the BSP for that number per its migration guide. With Flowella, no — Flowella supports WhatsApp Coexistence via Meta Embedded Signup.3
For a 7-agent HubSpot team running WhatsApp lead capture, Trengo's HubSpot integration is gated to the Pro plan at €499/mo annual (20 seats baked in, 18,000 conversations/yr), plus pass-through Meta fees, plus AI Journeys and HelpMate surcharges after the free tier. Flowella Pro is $159/mo flat, no per-user fees, with Meta fees paid directly into the customer's WhatsApp Business Account.7
Trengo's EU story is genuinely strong: Dutch HQ, AWS hosting, explicit GDPR commitments, Standard Contractual Clauses and a UK Addendum in the DPA. Flowella's story for European buyers is different but defensible: a UK parent (Discover Digital, Reading) and HubSpot's own EU data hosting option for HubSpot data, plus the customer's own Meta account for WhatsApp data. Neither is a deal-breaker; if EU data residency is the single most important criterion above all else, Trengo has the simpler story.1
A mature, multi-channel team inbox replacing email-plus-WhatsApp-plus-social with a single product, with Flowbots and AI Journeys for repetitive workflows. It is a good fit for B2C support teams in retail, hospitality, travel and automotive that are not already deep inside HubSpot.
Technically yes, since they operate on different planes: Flowella is a HubSpot Marketplace app for HubSpot-native WhatsApp Flows and workflow actions; Trengo is a separate unified inbox. In practice, customers tend to choose one path because the WhatsApp Business Account binds to a single BSP per number.

Founded 2017 in Utrecht, Netherlands by Patrick Meutzner, Marcel van de Weerd and Igo Trampe. $36M Series A on 1 September 2021 led by Insight Partners and Peak Capital; total raised $37.9M per Tracxn and Crunchbase. AWS hosting in Europe, GDPR commitments with Standard Contractual Clauses and a UK Addendum in the DPA. 3,000+ customers per trengo.com.
Trengo, Help Desk category, 100+ installs and 0 customer reviews as of 16 May 2026. Shared Data covers Companies, Contacts and Deals. No HubSpot workflow custom actions exposed in the listing. The marketplace plan-gating text references legacy Grow, Scale, or Enterprise plans while Trengo's current pricing page lists Boost, Pro and Enterprise; treat the listing as out of date.
Meta launched WhatsApp Coexistence in May 2025 via Embedded Signup, allowing a number to continue using the WhatsApp Business App while a BSP integration is live. Flowella supports Coexistence by design. Trengo's documented number-migration flow is a full BSP migration to Trengo, not Coexistence.
HubSpot's native Conversations Inbox has known limits around WhatsApp template management, structured replies and Flow handling. Flowella augments HubSpot rather than replacing it. Trengo replaces HubSpot's inbox with its own.
Trengo Flowbots are Trengo's own chatbot builder. AI Journeys is Trengo's no-code journey builder, described in the Trengo help centre as "Trengo's no-code customer journey builder that creates full-funnel conversation flows in 70+ languages in minutes" and currently in Beta. AI HelpMate is the AI agent. Chatimize records that "Trengo doesn't have conditions, so you cannot personalize conversations based on custom fields in Trengo" and Prospeo's 2026 analysis records that "AI HelpMate doesn't seem integrated with flows either". No native Meta WhatsApp Flows builder is documented.

Trengo's help-centre pricing pages and the Chatarmin pricing deep-dive both state that Trengo passes Meta's WhatsApp conversation costs through 1:1 with no markup. AI conversations carry a Trengo-side surcharge of €0.25 (annual) or €0.30 (monthly) per AI conversation once the free allowance is exhausted.
Boost €299/mo annual or €349 month-to-month (10 users, 6,000 conversations/yr). Pro €499/mo annual or €599 month-to-month (20 users, 18,000 conversations/yr). Enterprise custom. HubSpot integration gated to Pro plan and above. Additional seats €25–€30/user/month. Trengo migrated from per-seat to conversations-based pricing in 2024; this transition is the subject of multiple negative Trustpilot reviews in 2024 documenting price increases ranging from approximately 178% to 270%.
Claims have been written to comply with the UK Business Protection from Misleading Marketing Regulations 2008 and the CAP Code: each comparison is verifiable, sourced and dated. Trengo's marks are referenced descriptively and three rows where Trengo is genuinely stronger (team inbox, multi-channel breadth, EU data residency) are conceded openly.
