What Offstream does
Offstream is Vanta for carbon compliance. Today, every new infrastructure project, from data centers to biomass power plants has a complicated mess of local, state, federal, and private sector standards that they must understand and comply with to make their projects profitable. Offstream solves this by using LLMs to parse regulations, generate technical reports for customers, and manage 100,000+ operational data points on project’s lifecycles. We cut the time customers spend on compliance by 90% and at 1/5th of the cost of alternatives.

What the role involves
About Offstream 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. The Team 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. Our Culture 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: Transparency - Work should never be a place where you have to wonder about the success of the company, or the value of the contributions of you as an employee Positivity - We believe that Offstream is making a positive difference on the world, and so we come to work each day excited about the mission. We assume positive intent and solve for “what needs to be true” to tackle hard problems. We maintain a friendly and positive work culture so that all of our team members know that their contributions are valued, and people can do their best work. High Ownership - We are a team of highly motivated self-starters who enjoy responsibility and accountability for our specific focus areas. We operate with a shared sense of ownership for Offstream’s success, and support each other to achieve personal and company goals. The role 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. What you will own Building your own pipeline; you write your own prospecting sequences, build your own target lists, and do not wait for leads to be handed to you Working warm inbound and CEO-sourced opportunities quickly and to close, treating them as a supplement to your outbound motion, not a substitute for it Full-cycle ownership from first outreach through signed contract, including qualification, demo, negotiation, and close Documenting what works as you go; talk tracks, objection handling, and sequencing that become Offstream's repeatable playbook Accountability for your pipeline health; owning your numbers transparently Representing
