Lightspeed International Inc. was a software company founded in 1995 that developed voice control software for data communications networks, an early entrant in the mid-1990s effort to carry voice traffic over packet-switched data infrastructure. It was co-founded and led by CEO Lev Volftsun and backed at the early stage by Lightspeed Venture Partners. Cisco Systems, Inc. acquired the company in 1997, absorbing its voice-over-data-networks technology and team. The company has not operated as an independent entity since that acquisition, predates the public web API era entirely, and never published an API, developer portal, SDK, or machine-readable interface. Its legacy domain lightspeedinternational.com is now a parked HugeDomains for-sale listing with no live web surface. This profile is retained as a historical record of the Lightspeed Venture Partners portfolio and is not an active API provider. NOTE: unrelated to Lightspeed Commerce (the retail and restaurant POS company profiled at all/lightspeed and all/lightspeed-pos), to Lightspeed Trading at lightspeed.com, and — despite the shared name — a portfolio company of rather than an affiliate of Lightspeed Venture Partners (see x-disambiguation).
Lightspeed International is profiled on the APIs.io network. Tagged areas include Company, Telecommunications, Voice over IP, Networking, and Data Communications.
Regulatory Posture applies to this provider. Its tags matched the
Telecommunications regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

rationale: Entity is defunct (acquired by Cisco Systems in 1997) and published no API, developer portal, SDK, or specification.
It predates the public web API era, and no live web surface, documentation host, or base URL exists to probe or enrich.
No artifacts were generated; fabricating any would be unfaithful to the enrichment contract.
