As a procession of business vendors severed ties with the two-year-old site following the storming of the U.S. Capitol last week, Matze said in an interview with Reuters on Wednesday that he does not know when or if it will return.
"It could be never," he said. "We don't know yet."
The app said in a legal filing it has over 12 million users.
Matze said that Parler was talking to more than one cloud computing service but refused to disclose names, citing the likelihood of harassment for the companies involved. He said the best thing would be if Parler could get back on Amazon.
Parler on Monday filed a lawsuit against the company, which Amazon said has no merit. Matze said the company was considering suing other vendors but declined to say more.
Amazon cut Parler, a platform favored by supporters of U.S. President Donald Trump, off its servers this weekend for failing to effectively moderate violent content. Apple and Alphabet's Google also kicked Parler from their app stores.
"It's hard to keep track of how many people are telling us that we can no longer do business with them," said Matze.
Amazon on Tuesday filed exhibits that showed it had warned Parler late last year about vile and threatening language on its site before cutting off the platform after the attack on the U.S. Capitol.
Matze said Parler had also been booted from online payments service Stripe and from American Express and had lost its Scylla Enterprise database.
Parler could not send SMS messages after being banned by Twilio and could not use Slack to contact its "jury" of paid and volunteer users who make Parler content moderation decisions after being ditched by the workplace messaging app.
The vendors did not immediately respond to Reuters' requests to comment.
JOHN MATZE: Given how, I guess, irregular and how atrocious the attack was on the Capitol and everything that's gone on lately, you know, we feel that we need to go above and beyond that. And I think it's time to explore doing algorithms to flag content in advance. You know, we'll still keep the idea of people are innocent before proven guilty.
But you know, if we could get to a place where algorithms could be able to determine violations that are clear violations most of the time and then mark them as, hey, that can't go out, I'm sorry, you know, it just-- we think it's a violation. So if it's a false positive and you believe you're actually innocent, then you should be able to send it to the jury to make that determination. So we're trying to be more proactive about it, and we want to be very proactive about it because, you know, these things shouldn't happen.
You know, if everything is perfect and we don't lose any more vendors, which won't happen-- you know, you're talking, you know, half a week-- you start losing any more, you know, it could be never. I mean, we don't know yet.
Well, very importantly, we lost Scylla Enterprise. And for those who aren't familiar, you know, Scylla is a database. It's a very, very high-speed database. It's really the backbone of, you know, Parler's feed system and a lot of other components that we have. And so by losing them, that was really a big blow.
Other agreements-- like, we lost access to Stripe. So even if we were online, we can no longer process ads and have revenue. American Express said anybody-- nobody can pay for anything to Parler with American Express anymore. We've had quite a lot of vendors-- you know, Twilio, so we can't send SMS, Slack, so we can no longer talk to the community jury, who enforced our terms of service. So we don't have any communications with our own jurors anymore.
I mean, we're going to fight and do everything possible to come back as soon as possible, and I'd like to think that's viable next week or that's viable tomorrow. But really, in order to come back quickly, the best thing that could happen to us is, you know, we filed a request with the state to-- you know, during the lawsuit that we filed-- that basically says, we have to get back on Amazon because the damage of them taking us off is far beyond financial that we cannot recover unless they put us back.
And so that's the first step for us recovering is to get back there. Now, you know, the rest of it is really about whether or not we can find alternative places to go who will do business with us again. But at least clearing our name of this, youknow, or at least, you know, helping with that could help us find other people who will do business with us.
