Series A investors make very few investments that are time consuming and capital consuming. Often, a specific partner will make just 1 investment per year, and stick with that company for 7+ years. They'll also allocate ~$15m in capital to it (the $5m for the Everpix raise, plus another $10m for follow-on investments in future rounds). So they're not willing to take risks like this, it doesn't make sense with the model.
