The research half of outbound, done properly
OppStream is an AI growth intelligence platform for B2B business development. It finds the accounts worth contacting, explains why now is the right moment, identifies who to talk to, and writes outreach grounded in evidence you can check.
Outbound fails in the same place almost every time. Not at sending — sending is easy, and there are a hundred tools for it. It fails at knowing which companies are worth the effort this month, what has changed inside them, who actually decides, and what to say that is true. That work is slow, it is the first thing dropped when a quarter gets tight, and it is the reason most sequences read like they were written for nobody in particular.
OppStream does that half. It researches continuously rather than in bursts, shows the evidence behind everything it concludes, and hands you drafts you can argue with before anyone receives them.
Lena Siegel
Founder, OppStream
Lena Siegel founded OppStream after seeing how much time B2B sales teams spend searching for opportunities instead of having conversations with the right buyers. Built by salespeople for salespeople, OppStream reverse-engineers over a decade of proven business development expertise into AI-powered workflows that find the right companies, stakeholders, and opportunities, and turn them into real conversations.

The rules it works by
These are constraints rather than features. Each one costs something to keep, which is why they are worth stating.
Every claim carries its evidence
Scores come with the reasoning behind them and the source they rest on. You can disagree with a score and see exactly what it was built from, rather than being handed one number nobody can argue with.
It says when it does not know
An uncertain finding is labelled uncertain. A guessed email address is marked as a guess. A field it could not fill stays empty rather than being filled with something plausible. A confident wrong answer costs more than an honest gap.
It sends as you, not as us
Outreach goes from your own mailbox, your own domain and your own threads. Nothing is sent from a shared sending domain, so your deliverability is never pooled with anyone else's.
Nothing is synthesised that should be real
Personalised video uses your own face and your own voice. No cloned voices, no synthetic presenters, no avatar standing in for a person who never recorded anything.
You keep the last word
Research, drafts and video are yours to edit, override or discard. Automation runs only for the goals you switch on, inside limits you set, with a stop that halts everything at once.
Removal means removed
Somebody who asks not to be contacted is suppressed permanently across the whole workspace, and no colleague can undo it by tidying up a list.
Who it is for
And, as usefully, who it is not for.
Founders selling their own product
You are the first salesperson and the research is the part you never have time for.
First business-development hires
You are building the motion from nothing and need a list worth working before you need a bigger CRM.
Small outbound teams
Two to ten people who need more qualified accounts than they can research by hand.
Teams selling into considered purchases
Long cycles, several stakeholders, and a reason to call that has to be real.
It is a poor fit for high-volume transactional sending, for buying a contact list, and for anyone who wants a tool that will contact people without being asked. None of those is what it is built to do.
Questions people ask about us
Short answers, each one complete on its own.
- What is OppStream?
- OppStream is an AI growth intelligence platform for B2B business development. It researches companies that fit what you sell, explains why each one is worth contacting now, identifies the buying committee inside them, writes personalised outreach and video, and keeps following up until something happens.
- Who is OppStream for?
- Founders, first business-development hires and small outbound teams selling considered B2B purchases — typically one to ten people doing outbound, who need more qualified accounts than they can research by hand.
- How is OppStream different from a contact database or lead list?
- A list is a snapshot of who exists. OppStream researches why a specific company is worth calling this week — a funding round, a hiring pattern, an expansion, a leadership change — then finds who to speak to and writes what to say. It is the reasoning rather than the rows.
- Where does OppStream get its information?
- Public professional sources and published company material, the same places a researcher on your team would look. Every finding carries the evidence behind it, so you can check where something came from before acting on it.
- Does OppStream send email on my behalf?
- Only if you switch that on. Messages send from your own connected mailbox and domain, for the goals you choose, inside limits you set — a daily cap, which action types are allowed, and a stop that halts everything at once. It is off by default.
- Is my data used to train AI models?
- No. Your company data, your pipeline and your prospects are never used to train anything. They are used to answer your questions and nothing else.
- Is there a free plan?
- Yes, and it is a plan rather than a trial. It gives you one seat and ten opportunities in total, with no credit card and no countdown.
