Launch new services in weeks while your OSS/BSS keeps running
Change one domain at a time instead of a multi-year replacement: channels, partner products and AI agents connect through one governed layer, so revenue projects stop waiting for core migrations. Proven at Kyivstar (VEON) and in TM Forum Catalysts.
Shorten integration lead time without another core replacement
Put stable TM Forum contracts in front of legacy systems so channel and partner changes stop rippling through the back end, and replace each domain behind the same API when you decide. Measure it in lead time, not in migration slides.
Let multi-vendor AI agents act in your network — with evidence for every decision
Every agent-to-agent call is authorised for its specific purpose and recorded, so you add agents from different vendors without handing out permanent access. Proven in TM Forum Catalysts 2025 and 2026.
Take a partner product to its first customers in weeks, not quarters
Onboard third-party products, bundle them with connectivity and settle revenue on one repeatable process — no core BSS change for every new partner. At Kyivstar (VEON), a partner's satellite data service went from configuration to its first customers in three weeks.
Qualify the vendor in one review cycle
Check an EU company, published BSL 1.1 licence terms, a TM Forum Catalyst record and a named production reference — Kyivstar (VEON) — what an RFI asks for, in one place.
Check against the documentation how it fits your ODA landscape
Check the component model, deployment, authorization and the TMF Open API layer against exact anchors on platform.mef.dev — start with the architect's reading path.
Win operator projects without building every part yourself
Deliver the piece of an operator solution you do not have on a stack running in production at an operator — or launch your own products on it with our commercial support.

What we solve
What are you trying to solve?
01
Run multi-vendor AI agents under your control
Agents from different vendors start acting in operations, but no one can show which agent did what, on whose authority — and permanent access becomes the default.
Read more → 02
Charge IoT, M2M and network slices in real time
One tariff and one billing cycle for every device make IoT customers overpay or churn, and slices and 5G traffic need their own rating next to legacy.
Read more → 03
Modernize OSS/BSS one domain at a time
Every new channel, product or partner means another change in billing and CRM built decades ago; projects wait for the core, and a full replacement is a multi-year risk.
Read more → 04
Operator transaction processes in BPMN, compiled into a versioned application
The BPMN model is compiled into a versioned application, not interpreted as a script: a process change ships as a new version of compiled code.
Read more → 05
Launch and monetize partner products faster
Each partner deal needs its own integration and commercial setup; launches take quarters, and revenue sharing is reconciled by hand.

How we work
An agile launch: requirements can change as the project runs
The project runs in short releases: analysis, integration, migration, training and cutover repeat in each, so requirement changes during the project go into the next release instead of stopping delivery. Every workstream has an owner on the operator side and on ours.

A2A-T · Secure Passport · evidence
AI agents act in your stack under your control
- Agent Fabric-T
- Multi-vendor AI agents in your operations — under your rules, with evidence for every action.
- Trusted Gateway · Secure Passport
- Authorizes every call between agents for a specific purpose on attested attributes and records it as evidence.
- eTOM · Consent & delegation
- Agents follow the operator's TM Forum eTOM processes, and a sensitive action waits for the operator's consent — validated in TM Forum Catalysts 2025 and 2026.
- Knowledge Graph
- A semantic core over the operator's data: one picture of product, rule, process and owner, with the source and owner behind every chat answer and knowledge for agents such as Product Offering AI — the data stays in place.
