Unfortunately, it doesn't look like they have plans to use ACME. They do have a public API (StartAPI) for issuance, which is better than nothing, but they definitely missed an opportunity with ACME, IMO. Mainly, being the first CA with OV/EV support that would also benefit from the existing ACME ecosystem (i.e. server auto-configuration). StartEncrypt, the equivalent of an ACME client for their API, appears to be a closed-source binary blob with no documentation whatsoever (based on what's visible on their product landing page and what's inside the downloaded files).
