We're Explee. We send 10M+ emails a month and we need an engineer to take over deliverability. Explee is an AI SDR: you give it a URL and it does the whole SDR job itself, down to writing the emails. Getting into the inbox is the hard part. We burn a ton of money on it and nobody's on it full-time. THINGS WE CAN'T EXPLAIN ----------------------- 1. Unwarmed boxes from one vendor keep doing better than boxes another vendor warmed for a month. 2. Gmail → Outlook has a lower spam rate than Outlook → Outlook. 3. Warmup does almost nothing for Microsoft. We've thrown a lot at that one, no dice yet. Something breaks or surprises us every week: mailbox wear-out, 30 vs 35 sends a day, weekends, warmup schedules, you get the idea. You'll have to figure out what to test yourself. WHO FITS -------- - you like to experiment with things rather than just trust “common sense” - ~20% of the job is vendors: finding them and negotiating. twice already we've caught vendors selling cold mailboxes as "warmed". you'll spend $30-40k a week with them - you code with AI agents daily WHAT WE OFFER ------------- - $10-12k/month + equity - your metric is the P&L, directly. infra is what caps revenue today - $2M ARR, going for 20x this year, just closed a round. early days - small team: 9 people, everyone codes, we deploy on average every 24 minutes. a big part of the business runs on agents - we run our own GPUs and models - remote, full-time, UTC -3..+7 HOW TO JOIN ----------- 1. Write to [email protected], subject "250 OK". Plain text is fine. 2. Call with Alex (CEO), 30 min 3. Technical deep-dive, 90 min 4. Paid experiment with mailboxes 5. Offer -- Alex Kataev CEO, Explee
