Reach startups at the right moment, and their founders.

Oxpium builds the list of startups that fit your offer, finds the founders, tells you when one of them hires, grows or moves, and runs the campaign.

Describe the businesses you're looking for…

  • 50,000tech companies under five years old with employees in the US

[01]The list

The startups at the stage your offer fits.

A six-month-old company with two founders doesn't buy like a 30-person team hiring every month. Tell the agent the age, the city, the industry, the stage: it searches professional databases, public sources and websites, and leaves out the consultancies and freelancers.

  • An age

    Founded in the last year, three years or five: the founding year comes from professional databases and is checked against the website.

  • A team size

    Two founders, or 10 to 50 people: headcount comes from professional databases, so you can split solo founders from growing teams.

  • A product, not services

    The agent reads each company's website and only keeps the ones that sell a product, an app or a platform, not hours of consulting.

  • An industry, a city

    Healthcare, fintech, climate, around Boston or Austin: the agent reads who each startup sells to and puts it in the right group.

[02]Enrichment

The founders, not a hello@ address.

At a ten-person startup, almost everything goes through the founders: benefits, office space, laptops, the accountant. The agent finds them by company, verifies every email before adding it, and fills in the rest of the row from the website.

  • The founders

    The CEO, the cofounders, the CTO: the agent looks them up by company and title, and puts them on the same row as their startup.

  • Verified email and cell

    Every email is verified before it enters the list. The cell phone is added when one exists, which is often the case for founders.

  • Whoever runs operations

    Past 20 people, an ops or people lead often takes over benefits, office and equipment: the agent finds them by title when they exist.

  • What the website says

    The product, the buyers it targets, whether there is a careers page: the agent reads each startup's site and puts each answer in a column.

[03]Signals

Automations that see a startup change size.

A startup buys in steps: the first hires, the move out of the shared desk, the hiring wave. Each automation reruns its search on schedule and adds the startups that just crossed one of those steps to the top of the list.

2 startups posted a role since yesterday.

  • New job postings

    Every morning at 7 am, an automation flags the startups on the list that post a new role, with the title, the city and the date.

  • Headcount crossing a line

    On the 1st of the month, each startup's headcount is compared with last month, and the ones that just passed 10 or 25 people move up.

  • A careers page appears

    Every Wednesday, the sites are reread: a startup publishing its first careers page is about to hire, and will soon need desks and laptops.

  • Your own watch

    Every Friday, the sites are reread for a new office address, or for any other watch you write in one sentence, like a new product page.

[04]The campaign

A campaign that lands when the startup needs it.

Founders skip generic pitches. They read the one that arrives the week they hire, move or start a careers page. Every email starts from the step the startup just took, the agent rereads the site before each follow-up, and the sequence stops on the first reply.

Subject Benefits for the headcount people at startup

Hi first_name, startup just passed headcount people. Congratulations. At this size, the health plan is often what makes a candidate say yes or no. We set up group health, dental and 401(k) for teams under 50, in a week. Shall I send a quote? signature

Each variable is a column of your list, filled in by the agent.

  • Early in the morning

    Founders clear their inbox before the meetings start: Monday to Thursday, 8 to 9:30 am, and never on a Friday afternoon.

  • One step per message

    First hires, a new office, open roles: every email comes from one column of the list, and the agent rereads the site before the follow-up.

  • Calls from the browser

    You call from the browser. Every call is recorded, transcribed and then summarized on the startup's row, so nothing gets lost.

  • Stops on reply

    As soon as a founder replies, the campaign stops for that startup. You take the conversation from there, and the next follow-up never goes out.
