Poland's largest B2B sales agency
When an agency this size picks a vendor, that vendor has to scale to enterprise content workflows by default.
InStream Group runs lead generation, social selling, sales transformation and CRM for over 1,500 clients, and has done for more than 10 years, from offices in Poznań, Warsaw, Pleszew, London, Madrid, Rome and Bogotá. A tool that works for one founder is not the same as a tool that works across a whole sales floor, let alone dozens of client brands at once.
The client roster sets the bar. A sample of the 1,500+ portfolio includes Shell, EY, BMW, T-Mobile, Dell and Sage. So when InStream evaluated a content platform, the question was never whether it could produce one good post, it was whether it could run content operations at agency scale.
“InStream Group turned out to be a competent partner in building business relations and expanding our sales operations.”
— Hubert Paczkowski · Sage
A 4-tool stack with a ceiling
Before CaptureFlow, every piece of content passed through four disconnected tools.
Each tool did one job well, and the seams between them did all the damage. Advocacy distribution lived in one place, drafting in another, graphics in a third, scheduling in a fourth. Nothing carried a person's voice from one step to the next.
- Capture, draft, format and schedule in one place
- A voice model per person, so advocacy sounds human
- A dedicated workspace per client
- One login for the whole agency
- Sharebee for employee advocacy distribution
- ChatGPT for draft generation
- Canva for carousels and graphics
- A separate scheduler for publishing
That four-tool workflow created three compounding problems, and each one got worse as the agency grew.
Each tool solved one piece. Moving content between them took hours per week per person.
Templates and prompts produced corporate copy. The whole point of advocacy was getting diluted.
Running content across 1,500 clients through a 4-tool workflow meant every new client added tool-hopping hours.
20 minutes from demo to yes
The decision did not take a procurement cycle. It took one demo.
InStream was already paying for a content tool. Filip Duszczak, the Group CEO, saw a CaptureFlow demo and made the call on the spot.
“I will jump from our content tool to you in 20 minutes. You're much more advanced than they are.”
— Filip Duszczak · Group CEO, InStream Group · first reaction to the demo
CaptureFlow demoed in February 2026. The first 28 paid seats were live by the beginning of March, and the whole sales and marketing team was rolling out advocacy in parallel.
Two use cases on one platform
InStream did not run a cautious pilot. It put the platform to work in two directions at once.
The full sales and marketing team records short voice or video captures. CaptureFlow generates a month of multi-format LinkedIn content matched to each person's voice. Not a pilot, not a subset, the entire team rolling out advocacy in parallel.
The marketing team captures client founder and executive voice in 10-minute sessions and repurposes it into 15+ assets across LinkedIn, TikTok and Instagram. What used to take a full writer per client now runs from one platform.
Both use cases run on the same engine. CaptureFlow is an AI content agent that turns your expertise into weeks of on-brand content for every platform: you capture one idea in five minutes, and the agent, trained on each person's voice, reshapes it into native content for every channel. It is the same move as turning one video into ten LinkedIn posts, run across a whole agency.
35+ client brands, one account, zero new tools per client
After going live, InStream operationalized the agency model: 35+ client brands, each a dedicated workspace inside one account.
Each client gets its own workspace: a distinct voice, its own content calendar, and its own publishing flow. Every new client adds a workspace, not a tool. That is what makes CaptureFlow work for agencies running many brands rather than a single account. The numbers below are live counts from those workspaces.

That is what capture-first content looks like at agency scale. If you run an agency or a sales team that posts, see CaptureFlow pricing and set up the same multi-workspace model.
