❞
When we signed up for AetherX, we knew our product was strong, but our pitch deck and GTM strategy weren’t investor-ready. We needed a long-run practical advice. Aethermark became our co-pilots and were game-changers, helping us structure and close our Seed round seamlessly in
three months.

As a company in the AquaCulture space, finding investors who understood our unique market dynamics was a challenge. Aethermark’s sector mapping and investor outreach were incredibly targeted and effective. They didn’t rely on generic lists, every introduction was tailored outreach from their network.

❞
Before Aethermark, fundraising felt like a full-time job diverting us from operations. Their value lies in their ability to handle the entire process end-to-end till funds hit the account. Their financial model development was extremely helpful, and we highly recommend their result-oriented engagement model.
