kalkoAbout Kalko
Kalko finds what each company is working on internally but has not announced, using public sources like job posts and filings. It tells outbound teams which accounts need them now, who to contact and what to say. Every claim carries its source and date.
Key takeaways
- Kalko has three co-founders: Konstantinos Tsetsos, Aristogiannis Filippis and Dimitris Kaselouris.
- Kalko was selected for the first OpenAI Greek Startup Accelerator, run with Endeavor Greece, as 1 of 21 startups from more than 240 applicants.
- Plans start at $99 per month. The trial gives 200 credits and needs no card.
What does Kalko do?
- Ranks accounts by urgency of need, not only by fit.
- Reads signals most tools do not: public buyer complaints, roles written around the problem you solve, and reasons not to approach an account.
- Puts the source and the date on every claim.
- Re-scores accounts every week and proposes a few plays. Nothing sends until someone approves it.
- Works in Slack and in any agent that speaks MCP. API and MCP access come on every plan.
