Here's a current list of vendors I think are doing well.

Startups who are accelerating

support -- @plainsupport (sync and push comms to edges - teams/slack/discourse - is next level good)

docs -- @mintlify (Suddenly made all softwares documentation 10x better)

customer analytics -- @tinybirdco (IaC for data work, its fast with an excellentlocal experience.)

auth + subscriptions -- @ClerkDev

Analytics & Product Insights, gating experiments -- @statsig (runner up posthog, but statsig is much more precise on hardcore statistics)

secrets -- @doppler (excellent syncing experience)

mail etc. -- @resend (local email experience)

incidents, ops -- @rootlyhq (slack driven workflows are top tier)

ai agents / code -- @cursor_ai (still winning)

ticket/agent mgmt + triage etc -- @linear (elite quality)

hosting/deploys -- @Railway / @vercel (out-of-your-face infra to stay focussed on customers & product)

integrations marketplace -- @useparagon (iac for integrations, event driven and solid management. even ootb workflow builder canvas)

Incumbents (who cant seem to be beaten)

search -- Algolia

dataw -- BigQuery (gsheets native integration can't be beaten)

payments -- Stripe (too big to beat)

internal docs -- @NotionHQ (sort of incumbent, but cool)

all ops -- @datadoghq (so feature dense it can't be beaten, esp for speed of getting started)

code / cicd / automations -- @github (native gha mean nothing else needs to be used)
