Are you talking to other funds? You need to talk to as many funds as possible in a 2-3 week period to create leverage. Do not talk to a single or small number of funds in a process[0].

When I finished raising my pre-seed round I had a big list of investors that I had talked to, some a warm, some said no, some said yes. I always asked them if I could put them on my cool updated list, and then shared fun things with them (short emails - 4 sentences and a screenshot, hey look what we did!)
By the time it came to raise seed we were 2.5x oversubscribed in 2 weeks - because I had spent the previous year relationship building with all of them.
Remember VCs are reviewing a bunch of companies all at once, you are not the only thing they have to think about today.
Follow up in a few days, and send a short (20 seconds max) video attached in case they don’t have time to organise to see the demo.
VCs are busy so “do the work” for them, don’t ask a question - ask a question, anticipate the answer and then send the answer too.
These are long term relationships you are building so treat them as such.
