Participant-burst pricing for webinar hosts

A marketing manager at a 20-person company books a quarterly webinar with 150 external attendees. Their video conferencing plan caps at 50 participants — so they either upgrade to a plan priced for daily enterprise use or pay for a one-off webinar service at rates designed for agencies running dozens of webinars a month. Neither fits. The complaint 'pricing plans can get quite high, so it's best for larger teams that need to use it regularly' captures exactly this: occasional high-attendance events are structurally underserved because pricing tiers reward frequency, not occasional spikes.

The reason this gap persists is structural: incumbent vendors want customers on annual committed plans, not buying event-by-event capacity. An event-by-event buyer is expensive to support and hard to forecast, so no major vendor has built a clean pay-per-event product for the mid-market. The webinar tools that do exist are full-featured production environments priced as such — overkill for a quarterly company update or a client demo with 100 people on the line.

Without a per-event option, a small company's actual alternatives are: (a) upgrade their entire plan permanently for a single event, (b) use a consumer tool that looks unprofessional, or (c) cancel the large-format meeting entirely. Option (a) is the one most vendors quietly rely on. The recurring nature of the business is the event calendar — companies run quarterly all-hands, annual client days, monthly partner calls — so even though each purchase looks one-time, the customer relationship is genuinely recurring.

What to build

Build a per-event video conferencing product where hosts pay a flat fee per event based on max attendee count and duration — no subscription, no account required for attendees, with a branded waiting room, one-click recording, and a post-event attendance report exportable to CSV.

Where to start

Target professional associations and alumni networks that run annual or semi-annual member meetings — they have a fixed event calendar, a board that approves the spend, and no appetite for year-round subscriptions they'd use twice.

The hard part

Getting discovered at the moment of need is the core acquisition problem — someone searching for 'host a webinar for 150 people' is already in a buying moment, but SEO in this space is dominated by well-funded incumbents, so paid acquisition costs will be punishing until there's strong word-of-mouth.

How it makes money

Flat fee per event, priced by attendee tier (e.g., up to 100, 250, 500 attendees) and duration bracket — no subscription, with optional add-ons like post-event recording hosting billed monthly.
