Video conferencing startup Highfive raises $32M Series B led by Lightspeed Venture Partners, plans to double its workforce by end of 2015
Context & Ripple Effects
In March 2015, Highfive took a $32M Series B led by Lightspeed Venture Partners into a video-conferencing market where hardware-free meeting rooms were still unproven, committing to double headcount by year-end. The round made Lightspeed the startup's anchor backer — a position it kept through later rounds that brought Highfive's total funding to $77.4M.
The competitive backdrop hardened quickly: two years later Zoom pulled in a $100M Series D led by Sequoia at a $1B-plus valuation, leaving sub-scale challengers little room to grow independently. That gap is exactly where Highfive ended up — acquired by VoIP provider Dialpad in September 2020 rather than scaling on its own — making this 2015 round the opening move of an arc that resolved in consolidation.
First-order effects
- Highfive immediately gains the capital to double its workforce through 2015, accelerating engineering and go-to-market hiring against incumbent meeting-room vendors.
- Lightspeed deepens its concentration in collaboration software, a thesis it extended years later with a $12.7M Series A in Theta Lake, which builds compliance tooling for the very platforms Highfive competed on.
Second-order effects
- Sequoia's unicorn-priced bet on Zoom forced every other VC-backed conferencing challenger to either outspend on distribution or find an acquirer — pricing pressure that shaped Highfive's eventual path to Dialpad.
- For buyers, the influx of venture money across Highfive, Zoom, and event-platform plays like Hubilo meant rapidly converging features and aggressive bundling of hardware, software, and services.
Third-order effects
- If the pattern holds — massive rounds crowding the category, one leader breaking out, the rest absorbed by adjacent communications companies — enterprise video becomes a feature of consolidated UCaaS platforms rather than a standalone startup category, with investors like Lightspeed recycling proceeds into the surrounding tooling layer instead of new challengers.
The trend: Enterprise video conferencing is consolidating from a field of VC-funded challengers into a few platform owners, with sub-scale startups exiting via acquisition to communications providers.
