Work with me
Your WebRTC is misbehaving, and you need someone who has already seen this fail
Dropped calls you cannot explain. A voice-AI bet you cannot cost. A roadmap decision with no one senior to pressure-test it. I am not selling you a platform and I am not here to write your code. I help you make the call.
You are probably here because
Calls drop and no one can say why. Your team is guessing at getStats(), TURN, and packet loss. You need a read from someone who has debugged this a hundred times.
You are betting the roadmap on voice-AI. Latency budget, pipeline choices, guardrail gaps. Get it wrong and the demo works but production does not.
You need a senior RTC brain, not a hire. You are not ready to add a VP of real-time. You need one in the room for the decisions that matter.
A vendor is telling you what to buy. You want an independent read from someone with no platform to sell and no vendor's roadmap to push.
Ways to work together
From a fixed two-week read to having me in your corner every month. Pick the depth that matches the decision in front of you.
The four productized rungs carry public prices, so you know the number before the call. Deeper custom work is scoped together, so a large engagement is never anchored to a small number.
The fixed-scope services
Second opinion / health check
A fixed, two-week read on your real-time stack
For: a nagging feeling something is wrong, and no senior person to confirm it.
$7,000 · fixed · 2 weeks
A bounded read of your architecture, observability, and cost, with the risk ranked so you know what to fix first.
- Architecture, observability, and cost read
- Where the risk actually sits, ranked
- Written findings plus a live walkthrough
Transport & media audit
A deep teardown of your real-time transport
For: calls drop, media quality is inconsistent, or you cannot prove it holds up at scale.
from $12,000 · 3 weeks
A focused teardown of the layer your product lives or dies on: how media moves, where it breaks, and what it costs at scale.
- ICE / TURN / transport path teardown
- Media pipeline and quality analysis
- Scale, failure modes, and cost
- Includes the transport layer under voice-AI / LLM calling
Fractional RTC leadership 1 slot left
Senior real-time judgment, in the room every week
For: you need a senior RTC brain in your decisions, not a full-time hire.
$10,000 / month · capped at 2 clients
Standing product and tech leadership for real-time: in your decisions, reviews, and hiring, week to week.
- Standing product and tech leadership
- In your decisions, reviews, and hiring
- Capped at 2 clients at a time
Standing advisory and deeper work
Good fit, bad fit
Honest about what works. Honest about what doesn't.
Good fit
- You lead engineering on a real-time product, with a team of 5+ engineers past the prototype stage.
- You are weighing a build-vs-buy decision on WebRTC infrastructure.
- You want honest, independent guidance, not a vendor pitch.
Not a good fit
- You need someone to write the code for you. I advise, I don't build.
- Your product is pre-MVP and you need a general-purpose developer.
What consulting clients say
15 years of WebRTC. 5,000+ students across the courses, the WebRTC Insights newsletter, and hands-on work with the teams building this stack.
As we set out to build a mission-critical real-time voice and video platform for public safety, we needed clarity on architecture, scale, reliability, and behavior under real-world conditions. Tsahi gave us a clear strategic framework for how WebRTC should be deployed, managed, and scaled in a high-stakes environment. His guidance helped us refine our architecture, avoid costly mistakes, and move faster.
We had the challenge of building a generative AI application with WebRTC video and audio broadcast. Thanks to our collaboration, we were able to reach the maintainer of the open-source repository and define an in-depth, sustainable solution. What I appreciated most about working with Tsahi is his proactive and informative approach.
Tsahi is like our WebRTC GPS. He doesn't just tell us where to go, he also warns us about the potholes along the way. He's guided us on how to implement things directly in our code - not just high level advice, but actual practical 'this is how you should build it' recommendations. That has saved us from a bunch of debugging marathons.
I have worked with hundreds of consultants across my Wall Street and startup career. I can categorically say that none have provided as much value as Tsahi Levent-Levi. He takes a very direct approach with his clients and is quick to let you know what falls inside and outside of his wheelhouse. Tsahi is also incredibly efficient with his time.
I met Tsahi when I just started out my company. Within a few days I realized he saved me weeks of work thanks to his expertise. It's now been 3 years and we continued to work together even though my team is much bigger.
Questions people ask
How much does WebRTC consulting cost?
A fixed second-opinion health check is $7,000. A transport and media audit starts at $12,000. Standing advisory (Tsahi In Your Corner) is $3,500 per month, and fractional leadership is $10,000 per month. Larger custom engagements are scoped individually.
Can I get a one-time review instead of a long engagement?
Yes. The $7,000 two-week health check is built exactly for that: a fixed, bounded read of your real-time stack with no commitment beyond it.
Are you independent, or tied to a vendor?
Independent. I have no platform to sell and no vendor's roadmap to push. That independence is the reason clients bring me in.
Do you work with voice-AI and LLM-based calling?
Yes, from the real-time transport and media side, which is included in the audit. For a deeper standalone voice-AI readiness review, get in touch and we will scope it together.
How do we start?
Schedule a call and tell me the decision you are facing. We will figure out which rung fits, and you leave the first call with a direction whether or not we work together.
Tell me the decision you are facing
One call. I come prepared, you leave with a direction. We decide together if there is a fit.
