Vanta for carbon compliance
Offstream is the de facto dMRV and compliance platform for biochar project developers in the US. We are backed by Y Combinator, FundersClub, Collab Fund, Ponderosa VC, and strategic angels across the carbon markets ecosystem. Unlike tools that only engage once a project is operating, Offstream supports developers across the full project lifecycle: feasibility and opportunity assessment, credit origination, and maintaining ongoing credit flow. We work with 50+ projects under development or in operation today, and are a trusted partner of major registries, such as Isometric, Puro.earth, and Rainbow.
Offstream was founded by Varsha Walsh and Zach Janicki.
Varsha (CEO) has spent her career at the intersection of carbon markets and project development, working as a developer, broker, and buyer before founding Offstream. Prior to Offstream, she held roles at Indigo Ag and Patch, where she built deep expertise in voluntary carbon markets, biochar and biomass crediting methodologies, dMRV infrastructure, and lifecycle assessment. She experienced the compliance and MRV pain point firsthand across every seat at the table, and built Offstream to solve it. Varsha holds an MBA from Harvard Business School.
Zach (CTO) has spent his career building software at early-stage startups, most recently as the first engineer at Repool (YC S21), where he built a product from the ground up that reached $1M in ARR. He has deep experience in regulatory-heavy spaces including finance and insurance, and knows how to build greenfield products that scale with a rapidly growing company.
At Offstream we care deeply about the impact we are making on the planet and want our work to encapsulate a successful business and make a meaningful dent in the climate crisis. We work at the intersection of climate x capitalism.
Our culture is anchored around:
This is Offstream's first dedicated sales hire. You will own the full revenue cycle from first outreach to signed contract, working directly alongside the CEO to scale a motion that is already generating inbound interest, warm referrals, and channel-driven pipeline. The first segment of customers you’ll be responsible for is prospective and current biochar producers globally, but as we scale, this will evolve.
You will not be handed a polished playbook. You will help write it. The right person thrives on figuring out what works, iterating fast, and closing deals in a technical market where credibility matters as much as charisma.
This is the first sales hire at Offstream. The person who takes this role will have real influence over how we sell, who we sell to, and what the commercial motion looks like as the team scales. You will work directly alongside the CEO from day one, with full visibility into pipeline, strategy, and product direction.
As Offstream grows, there is a clear path to a revenue leadership role for the right person. This is not a role where you execute someone else's playbook; it is where you help write the one the next ten people will use.
Compensation includes a competitive base salary, uncapped commission, and a meaningful equity stake — as the company's first commercial hire, you will be compensated like one. We are hybrid in Denver and San Francisco, with travel to conferences and site visits throughout the year.
Denver, CO or San Francisco, CA preferred

We’re live today with 10+ clean tech developers, helping them simplify the complex web of compliance across tax credit requirements, voluntary carbon market standards, and local, state, and federal regulations. The market for clean tech projects is rapidly growing fueled by $500B+ IRA incentives from the US, purchase commitments made by large corporate buyers, compliance market mechanisms, and the climate crisis. Offstream enables the launch and scale-up of projects that are critical to net zero.
